Harmit Singh’s research is focused on the promotion of more acceptable natural food ingredients and bio-friendly food processing technologies such as membrane and enzyme technologies. His recent projects include purification and concentration of natural food colors using membrane technology and evaluation of antioxidant properties and stability of these colors during application. His research is also focused on application of enzymes as processing aid to affect protein solubilization, allergen degradation and other food industry processes.

Abstract:

Statement of Problem: Membrane technology has become a potential technique to remove unwanted molecules and concentrate the natural colors without thermal treatment. However, this technology needs to be investigated for the efficiency and changes in ACNs quality throughout the process. The Purpose of this was to purify and concentrate ACN extract from red cabbage using membrane filtration; and to compare the color intensity, aroma, the antioxidant capacity, phenolic content and chemical composition of the purified anthocyanins.

Methodology: ACNs were extracted from red cabbage by constant agitation using a 0.5% HCl solution. The extracted suspension was centrifuged and clarified using Microfiltration (MF) membrane to remove any unwanted particles. The resulting permeate with color was collected and concentrated using Nanofiltration (NF). The final permeate and retentate were analyzed for composition and other characteristics. Reverse Phase High Performance Liquid Chromatography (RP-HPLC), colorimeter, antioxidant capacity and total phenolic content were used to evaluate any changes.

Findings: There was a 42% decrease in total phenolic content from raw sample to concentrated sample, while the antioxidant capacity remained the same at 16 mg/L throughout the whole process. No change in RP-HPLC was observed throughout the purification process indicating the concentration process did not affect ACNs composition. The NF membrane proved to have a good anthocyanin retention since no anthocyanin content was found in the permeate. Interestingly, the undesirable aroma from red cabbage was less intense in the concentrated sample as compared to the raw sample and will need further study.

Abstract:

Mushrooms have long been part of the human nutrition. In recent years, mushrooms have attracted much research attention due to being important natural resources of bioactive compounds, antibacterial, antioxidant, and anticancer agents. Tricholoma terreum (Schaeff.) P.Kumm. is an edible mushroom growing in many districts of Europe; however, the fruiting bodies of this wild mushroom was suspected as toxic and should be consumed after cooked [1]. In the present study, T. terreum were collected from MuÄŸla, Turkey. The influence of baking on the fatty acid profile and antioxidant activity of the extracts of T. terreum obtained by traditional, Soxhlet and ultrasonic assisted extraction technique was investigated. The fatty acid profile and antioxidant properties based on free radical scavenging activity was studied using GC-MS and spectrophotometer, respectively. The fatty acid content and radical scavenning activity of mushroom extracts were varied by using on the bases of different solvent extractions and several extraction techniques. The linoleic and palmitic  acid found to be the main fatty acids in baked samples while linoleic, linolenic and oleic acid in unbaked ones. When mushroom was baked, palmitic acid and linoleic acid percentages of all extracts increased, whilst linolenic acid decreased. Among the all extracts, the water extract of unbaked and baked mushroom obtained by Soxhlet extraction was found to be the most active on DPPH^• assay. It was observed that the baked mushroom extracts exhibited less activity than those of raw extracts

Monira Pervin has completed her PhD studies in Nutritional Biochemistry at Graduate School of Nutritional and Environmental Sciences, Department of Food and Nutritional Sciences, University of Shizuoka, Japan with thesis entitled: “Studies on biological effects of plant lectins on animal cells and tissues”.  At present, she is working as postdoctoral research assistant in Tea Science Center, Graduate School of Integrated Pharmaceutical and Nutritional Sciences, University of Shizuoka, Japan on prevention of brain aging by green tea catechin using human neuroblastoma SH-SY5Y cells and mouse brain tissues. Her work has been reported in fifteen published paper in peer-reviewed Journals

Abstract:

The consumption of green tea catechins (GTCs) suppresses age-related cognitive dysfunction in mice. GTCs are composed of several catechins, of which epigallocatechin gallate (EGCG) is the most abundant, followed by epigallocatechin (EGC). Orally ingested EGCG is hydrolyzed by intestinal biota to EGC and gallic acid (GA). To understand the mechanism of action of GTCs on the brain, their permeability of the blood brain barrier (BBB) as well as their effects on cognitive function in mice and on nerve cell proliferation in vitro were examined. The in vitro BBB permeability (%, in 30 min) of EGCG, EGC and GA was 2.8±0.1, 3.4±0.3 and 6.5±0.6, respectively. The permeability of EGCG into the BBB indicates that EGCG reached the brain parenchyma even at a very low concentration. The learning ability of SAMP10 mice (a mouse model of brain senescence) that ingested EGCG (20 mg/kg) was significantly higher than of mice that ingested EGC or GA. However, combined ingestion of EGC and GA showed a significant improvement comparable to EGCG. SH-SY5Y cell growth was significantly enhanced by 0.05 µM EGCG, but this effect was reduced at higher concentrations. Co-administration of EGC and GA increased neurite length more than EGC or GA alone. These results suggested that cognitive dysfunction in mice is suppressed after ingesting GTCs when a low concentration of EGCG is incorporated into the brain parenchyma via the BBB. Furthermore, the additive effect of EGC and GA suggests that EGCG sustains a preventive effect after the hydrolysis to EGC and GA.

I have been working at Osaka Municipal Technical Research Institute since graduating from KONAN University in Kobe, Japan, and have been engaged in research into microbial enzymes, such as glycosidases, glycosyl transferases, oxidases. I received a doctoral degree  on “Levan degrading enzymes”. I have also been interested in enzymatic and microbioal oxidation of saccharides. Productions of Lactobionic acid, D-glucuronic acid and D-glucaric acid are good  examples for effective conversion of aldose to aldonic acid, uronic acid and aldaric acid.

Abstract:

Objective:  Concerned about utilization of lactose and development of high-soluble calcium supplement, with an interest on biological oxidation of oligosaccharide, we examined microbial and enzymatic oxidation of lactose and aimed to establish  effective production systems of calcium lactobionate. Lactobionate, b-1,4-D-galactosyl-D-gluconate, is an oxidized product of lactose. It has been reported to have mineral-absorption-promoting effects, Biffidobacterium-growing activity, moisturizing effect, and high solubility in water. Despite its useful properties, lactobionate has been supplied only in a small scale by chemical oxidation because there is no easy and efficient way to produce it.

Results:  As for fermentation, we isolated a mutant strain of Burkholderia cepacia which has no b-galactosidase activity to avoid hydrolysis of lactose and has sugar-tolerance to react with concentrated lactose. After 4-day cultivation, lactose was completely disappeared and the equivalent molarity of calcium lactobionate was accumulated. In the case of 10-day-fed-batch culture, the final concentration of the product reached 400 g/L in 100% yield. The product was purified from culture supernatant by ethanol precipitation.

 As for microbial conversion, cells were incubated with 100 to 200 g/L of lactose and half mole equivalent calcium carbonate to lactose. The oxidation activity of the cells was defined as the amount of cells which produced 1 mmol of D-gluconate per minute from 0.1M D-glucose under the assay conditions. When 2 U/mL of cells were incubated with 100 , 150 and 200 g/Lof lactose, it took 18, 27 and 48 h for 100% conversion. Reuse of resting cells was available for repeated conversions. Cells of Gluconobacter sp.were also used for microbial conversion. As for enzymatic conversion, we isolated a strain of Paraconiothyrium sp. which secreted a stable oxidase in culture. These biological conversion systems of lactose were effective to produce calcium lactobionate with high yield, no by-product, easy purification, and easy operation in one-pot synthesis.

Dina Keumala Sari has her expertise in vitamin D and polymorphism vitamin D receptor gene. Her interest in vitamin D creates a theory about microevolution in North Sumatera women in Indonesia

Abstract:

Background: A large proportion of women living in tropical regions experience Vitamin D deficiency especially in North Sumatera, Indonesia, and lifestyle being one of the predisposing factors. Other causes may be attributed to the presence of polymorphism in the Vitamin D receptor gene TaqI and BsmI.

Objective: To assess the effect of 1000 IU vitamin D supplementation on 25(OH)D serum and calcium levels in North Sumatera women with vitamin D re ceptor gene polymorphism (TaqI and BsmI).

Design: The study was a parallel clinical trial, thirtysix subjects with vitamin D receptor gene polymorphism (TaqI and BsmI) were selected using certain criterias. The subjects were devided into two groups using block randomization. Nineteen subjects in vitamin D group received 1000 IU vitamin D supplementation per day and dietary counseling (D), while seventeen subjects in counseling group received placebo and dietary counseling (C). Serum 25-hydroxyvitamin D and calcium levels were assessed on day 0 and 28. Before and after treatment, dietary intake were assessed with 2x24 hour recal methods.

Results: Nineteen subjects in D group and seventeen subjects in C group completed the study. There was no significant differences in baseline data both groups. After 28 days treatment, there was no significant differences in nutrients intake in two groups except vitamin D intake in D group. There was significant increase in 25(OH)D serum level in D group while no change was observed in the C group (p=0.04). Serum calcium concentration showed no significant change in both groups. There was significant differences between both group but all subjects did not reach normal value in 25(OH)D serum level (normal value >30 ng/mL).

Conclusions: The result shows that vitamin D deficiency can occur in women with Vitamin D receptor gene polymorphism even already supplemented with 1000 IU vitamin D.

Abstract:

Chemo-radiotherapy (CRT) causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea and vomiting, with consequent worsening of malnutrition. It is well known that radiotherapy is invariably associated with mucositis, xerostomia, dysphagia, haematological toxicities and other acute side effects, whose incidence increases when chemotherapy is also administered, and that oral mucositis incidence leads to higher unplanned breaks and delays in radiotherapy administration. In addition, in many patients such toxicities may be very severe and even life threatening and may lead to treatment interruptions that are invariably associated with poorer outcome. 

This presentation will review best practice in the nutritional management of patients undergoing chemotherapy and radiotherapy

Iris Shai is a professor of Nutrition and Epidemiology at BGU and a visiting Scientist at Harvard School of Public Health in the field of nutrition and chronic diseases. Her focuses are long-term, compressive dietary randomized controlled trials (RCTs), performed in standards of drugs trials, and long-term cohorts. Following her fellowship in Harvard School of Public Health, she performed the 2-year Dietary Intervention Randomized Controlled Trial (DIRECT) and 4-year follow-up, comparing the effects of low-fat, Mediterranean and low-carb diets on cardiometabolic risk and plaque regression. In her next RCT she addressed the 2-year effect of moderate alcohol in type 2 diabetes and her current whole-body MRI RCT focus on dynamic of  human specific fat depots and fuel metabolism across dietary strategies

Abstract:

BACKGROUND: It remains unclear whether specific lifestyle strategies can differentially mobilize fat depots/ectopic-fat-deposits.                                                                                                        

METHODS: During an 18-month trial in an isolated workplace with monitored, provided lunch, we randomly assigned participants with abdominal obesity/dyslipidemia to iso-caloric low-fat(LF) or low-carbohydrate/Mediterranean(LC/MED) diets. After 6 months, we re-randomized half of each arm to moderately-intense physical-activity (PA⁺;80%-aerobic; free gym membership). We performed whole-body magnetic-resonance-imaging (3-Tesla-MRI) at 0,6,18 months

RESULTS: Of 278 randomized participants [age=48yr;88% men; body-mass-index=30.8kg/m²) 86.3% completed the trial. While the caloric deficit was similar, the LF group preferentially decreased saturated/unsaturated fats (p<0.001), and the LC/MED decreased carbohydrates (p<0.001) and trans-fat intake (p=0.029 vs. other diet). The PA⁺ group increased their MET/wk (p=0.009 vs. PA^-). Fat depots/deposits were significantly reduced to different degrees [Hepatic:(-32%);deep-subcutaneous-adipose-tissue(SAT):(-29%);visceral-adipose-tissue(VAT):(-25%);superficial-SAT:(-19%) and intra-pericardial:(-14%(-25mL))], with lesser changes of renal:(-9%);intermuscular:(-2%) and pancreatic-fat:(-1%). Although weight loss was comparable, LC/MED^PA+ favorably reduced waist-circumference (p<0.05), and induced -14% further loss of intra-pericaridal;p=0.003, -4% VAT;p=0.037 and -1.9% pancreatic-fat;p=0.007, compared to LF^PA- changes (reference-group; weight-loss-adjusted for all). LC/MED decreased hepatic fat beyond LF diet by -15%;p=0.044. Conversely, renal-sinus and femoral-intermuscular fat dynamics were similarly altered by lifestyle strategies. VAT and intrahepatic fat loss associated with an improved lipid profile, and deep-SAT loss with improved glycemic control.  

CONCLUSIONS: Human depots/ectopic-fat-deposits are substantially variable in their capacity to respond to different long-term moderate weight-loss strategies. LC/MED diet, particularly with PA, can favorably enhance fat mobilization in several depots. These findings may suggest defined lifestyle protocols for targeting specific fat storage sites.

Abstract:

Aging affects all tissues and organs in humans and animals including dogs and cats. Some senior dogs and cats eventually develop cognitive impairment and dementia called cognitive dysfunction syndrome (CDS), a condition similar to Alzheimer’s disease in people.  Since CDS is not a curable condition, our non-invasive research has been focused on nutritional strategies that promote healthy brain aging in dogs and cats. We have developed two nutritional solutions to enhance cognitive functions in dogs and cats. The first solution is to address the reduced ability of aging brain cells to utilize glucose as energy by feeding medium chain triglycerides (MCTs), and our studies have confirmed that MCTs enhance cognition in aging dogs. The second nutritional solution is to minimize known risk factors associated with brain aging. Since there are multiple risk factors, we have developed a nutrient blend targeting those risk factors and confirmed that the nutrient blend significantly enhances cognitive functions in middle-aged and aging cats. In summary, our research demonstrates that optimal nutrition can enhance cognitive functions in healthy aging dogs and cats. What we have developed for pets will help facilitate the development of similar nutritional solutions for people.

Abstract:

Human studies are essential to obtain evidence of beneficial effects of nutritional interventions on health. Clinical nutritional development plans include a range from small pilot trials to well-designed confirmatory studies, following good clinical practices.

Nutrition interventions are generally safe compared to pharmaceutical compounds. Regulatory guidance limits the benefits of nutrition to the maintenance of normal function or the reduction of accepted risk factors. Therefore, nutritional trials do not necessarily follow the same development process as pharmaceutical products. The objectives focus more on maintaining health and preventing risk factors for disease rather than showing efficacy in disease conditions. Clinical trials in the nutritional field have specific challenges to overcome in terms of population, intervention, design and methodology.  Additional challenges are the lack of learning phases, small beneficial effects, high heterogeneity of the responses and difficulties in finding appropriate endpoints.

In recent years, the use of adaptive design methods in clinical trials has received much attention due to its flexibility and efficiency in clinical development. In practice, adaptive design may provide the opportunity to modify certain aspects of the trial design whilst the study is still ongoing, without violating the quality and the integrity of the data. However, introducing more flexibility may come with many difficulties: major adaptations of on-going trials may result in designs unable to address the original scientific/medical questions. In addition, fundamental differences between pharmaceutical and nutritional research potentially trigger limitations but also opportunities for the application of such innovative design.

The aim of this work is to highlight specificities and challenges in nutritional clinical trials, review the concepts of adaptive design and then address the advantages, limitations, and feasibility of commonly considered adaptive designs. Statistical, clinical, operational and regulatory aspects of implementing adaptive designs will be discussed.

His current focus is on the implementation of healthier dietary practice through improved understanding of self-control

Abstract:

Statement of the Problem: Numerous health problems and cause of death have been attributed to dietary factors. However, further nutritional education alone is insufficient, as APA surveys have shown that although American participant’s most common goal was to improve their diet for better health, 94% of respondents were unable to do so and cited insufficient self-control as the main barrier to success. However, as yet there are no validated models of the relationships between self-control and dietary outcomes or moderating psychological constructs. Further, scales do not yet exist to measure these constructs to measure potential targets for clinical intervention or future research.

Aims: The current study is validating new scales for measurement of psychological-nutritional constructs in self-control for dietary satisfaction.

Methodology & Theoretical Orientation: 3 new scales are under development and validation using factor analysis and convergent/divergent validity with existing scales. Based on previous models of self-control, a new model of self-control for satisfaction with dietary behavior will be tested.

Findings: The scales to be created for model testing are currently being validated, with research scheduled to be completed by March 2017. Conclusion & Significance: The creation of the scales displayed in Figure 1, a proposed model of self-control for satisfaction with dietary behavior, will contribute improved understanding of how self-control and related constructs interact with dietary goals to predict dietary outcomes for better health.

He holds an MSc in Food Economics & Marketing (University of Reading) and BSc in International Marketing & Communications (Hochschule Bremen and University of Valencia).

Abstract:

It is undeniable the fact that the probiotic market is suffering a transition where new trends are coming across. In addition to this, regulation (by means of EFSA in Europe) is extremely relevant. New trends and Health Claim Regulations entail new challenges and impact on innovation.

Furthermore, the industry is moving at a fast-growing pace so that products containing probiotics are attractive to both food and pharma companies.

New indications from different nature -the so called third generation claims- appear more and more as hot topics/niches (atopic dermatitis, psoriasis, stroke, sport nutrition, gut-brain axis), abandoning soft communications such as digestive health or immune system support.

In this sense, new and interesting final product ideas are being developed within the industry, where probiotic producers should acquire a relevant role, going together with pharma and food industry based companies as well as contract manufacturers in order to create outstanding synergies and fulfill new market needs.

Abstract:

Silkworm pupae are good resources of edible oil that is especially rich in unsaturated fatty acids and considered an excellent dietary supplement for hyperlipidemia. In order to investigate the effects of silkworm pupae oil (SPO) on the lipid profile and oxidative stress, dyslipidemic-diabetic Wistar rats (n = 50) were divided into five diet groups of 10: normal control (C); high-fat diet control group (HF); and three other groups fed a high-fat diet with SPO supplementation (1, 2, or 4 mL•kg-1•d-1) orally. Groups fed with SPO had significantly lower concentrations of serum total cholesterol (TC) (P<0.05) and low-density lipoprotein cholesterol (LDL-C) (P<0.05) compared with the HF group. In regard to antioxidant parameters, except for levels of glutathione peroxidase (GSH-Px) in the liver, 2 and 4 mL•kg-1•d-1 of SPO supplementation leaded to higher total antioxidant capacity (T-AOC) (P<0.05), superoxide dismutase (SOD) (P<0.05) and GSH-Px levels (P<0.05) and lower malondialdehyde (MDA) levels (P<0.05) both in serum and liver versus the HF group. The study indicated that supplementation with SPO can improve lipid profiles and alleviate oxidative stress in dyslipidemic-diabetic rats induced by high-fat-diet, which showed great potential in ameliorating disorders of glucose and lipid metabolism.

Abstract:

Mexico has a high prevalence of stunting in children and adolescents, due to poor nutrition. Paradoxically, too many Mexican children and adolescents are currently overweight or obese (OW/OB). The dual-burden of stunting (low height for age) and OW/OB are nutritional conditions that increase the risk of developing chronic degenerative diseases in adulthood. The persistence of high levels of stunting in southern regions of Mexico, such as Yucatan, may be due to diet changes (nutrition transition) that Yucatecan population has experienced in recent years. Vitamins, such as folic acid (FA) and VB12 are micronutrients necessary for normal metabolism and growth. The relationships between the intake of these micronutrients and growth rate were identified. The impact of micronutrient consumption on body composition was also investigated. The sample population comprised 273 adolescents (152 females) aged 10-18 years, from Merida, Mexico. Dietary information was obtained using a food frequency questionnaire (FFQ) covering 106 local foods. Anthropometric and body composition measurements were taken, and socioeconomic data were gathered. Data were collected between September 2011 and July 2012. Over 50% of participants had inadequate consumption of both vitamins: 64% had inadequate intake of FA and 69% of VB12. Almost half (46.9%) were either short or stunted, and 33% were at risk of OW/OB. A higher risk of presenting OW/OB was found for participants with FA intake less than the RDI of 400 μg/day and for those with VB12 intake less than the RDI of 2.4 μg/day. No relationship was found between body fat percentage and the consumption of FA or VB12

Abstract:

Objective: To determine the effects of a diet rich in lycopene, the practice of physical exercise or association between them on levels of blood lipids in adults with dyslipidemia.

Material and Methods: It is an experimental study with duration of 12 weeks. The diet was designed rich in lycopene (50mg / day), the standard diet and exercise program. Before and after the intervention lipid profile of the participants was determined. Involved people between 21 and 64 years old, randomly divided into 4 groups: two standard diet (one did exercise and one not), and the other two with diet rich in lycopene, one did exercise and one not. For each indicator behavior regarding their group arithmetic mean and standard deviation were used. Later ANOVA was used to demonstrate the significance and finally the post hoc Tukey test.

Results: 48 participants completed the study of which 35.4% (17) were male and 64.6% (31) female. The mean differences were significant post-pre cholesterol (p = 0.004) and LDL (p = 0.001). The mean difference between groups was significant for cholesterol between the standard diet with exercise and diet rich in lycopene with exercise and vice versa (p = 0.002). For the LDL was significant difference between the standard diet and exercise group with the other groups.

Conclusions: The lycopene-rich diet (50 mg / day) for 12 weeks significantly reduce LDL cholesterol levels and blood. Exercise training (4 days a week for 60 minutes) for 12 weeks significantly decreased blood levels of LDL when combined with the standard diet and cholesterol levels and LDL to be associated with diet rich in lycopene.

Abstract:

Recently, scientists interested in functional food, especially probiotic food which has many health benefits. Probiotic microorganisms expose to many risks during their presence in food products and after passing through gastrointestinal tract as well. Therefore, the a main goal of this study to try to keep probiotic bacteria alive in date products during storage period and after eating. Free and calcium alginate microencapsulated Bifidobacterium lactis Bb-12 were mixed with date paste and date syrup (Dibs) and exposed to simulated gastrointestinal conditions, to observe its effects on viability of  on B. lactis. The results showed that date paste and Dibs have a protective effect to the free bacteria and increased protection of encapsulated bacteria when compared to free bacteria without mixing with a date paste and Dibs. The viable counts of probiotic bacteria were numerated in date paste and Dibs during storage. At the end of the seventh week from storage period, the numbers of free B. lactis were reduced in both date paste and Dibs for up to 10⁶ cfu/g, while the numbers of encapsulated bacteria remained at 10⁷ cfu/g. The microencapsulated bacteria retained the numbers up to 10⁶ cfu/g until week ten. The changes in pH values, production of organic acid and color of date paste and Dibs were monitored during storage period. The sensory analysis of date products fortified with probiotic bacteria were evaluated. The results showed that the addition of both free and encapsulated probiotic bacteria did not show any significant effect on the sensory properties of date products. This study has  shown the microencapsulation protected Bifidobacterium lactis Bb-12 from the high sugars concentration of date products and simulated gastrointestinal conditions. Such of this product will provide an alternative probiotic food choice for consumers and could be particularly appealing to children.

Abstract:

Natto and tempeh are indigenous Asian soya fermented foods which were originated in Japan and Indonesia, but now also being consumed in all over the world. Importantly these soya based fermented foods are rich in phytoestrogens genistein and daidzein. Phytoestrogens are plant derived isoflavone compound which has similar structure and antagonize human estrogens. While some of previous research indicates that phytoestrogen may act as anti-carcinogenic agents and inhibits tumor growth in patients with breast cancers, some of the other scientific literature says that “they stimulate tumor growth and therefore leading to practical issue for safety of food with phytoestrogen such as soya. Also some of research data say that phytoestogens have increasing attention due to the beneficial effect on glucose, lipid metabolism (protection against cardiovascular diseases), osteoporosis and complications related to menopause. However these health benefits of soya and phytoestrogens are controversial issue as number of research findings has indicated inverse results as well. Moreover contrasting results have been recorded on its cancer protection ability (hormone dependent cancers such as breast and prostrate) and due to these negative findings health authorities of some countries have indicated maximum daily intake level for phytoestrogen. Therefore preparation of indigenous Asian fermented legume foods such as natto and tempeh using other comparable legume is an interesting alternative to avoid overdosing above mentioned compounds. The aim of this study was to determine the amount of genistein and daidzein content of lupin and fermented lupin (lupin natto and tempeh) and whether fermentation time affected the genistein and daidzein content of lupin. Lupin tempeh and lupin natto were prepared using either whole seed (WS) or de-hulled seed (DHS). Analysis for genistein and daidzein content was conducted using HPLC for time points zero, 12 h, 24 h, 36 h, 48 h and 72 h after fermentation. Repeated measures ANOVA with source of lupin as between-subject factor was independently run for lupin tempeh and lupin natto. Results revealed that the amount of genistien and daidzein significantly increased with time in both tempeh and natto. Both isoflavones peaked at 48 h in lupin tempeh and earlier at 36 h in lupin natto. WS tempeh and WS natto had significantly more genistein than WHS tempeh and WHS natto. Diadzein content of WHS tended to be higher than WS across both products. It is concluded that, lupin and fermented lupin have very low amount of genistein and daizein compared to soya bean. Therefore, it is safe to consume without risk of phytoeastrogen overdosing. Fermentation time increased the amount of genistein and daidzein content in both lupin tempeh and natto and the form of lupin raw material used affected the genistein level and to some extent the daidzein content of fermented products.
