  • The article demonstrates a method of studying human health and nutrition by applying a multi-disciplinary approach and examines how humans developed and survived by adjusting to their environment. This process involves physiological, cultural and genetic adaptation both independently and interactively. This study postulates that a sound human health may be the result of balance between nutrition and environmental conditions. It is noted that there is a positive correlation between malaria and fava bean intake, and sickle cell anemia and cassava intake. It is also suggested that the difference in disease structure in soybean and non-soybean consumption cultures can be explained by an ecological approach to studying nutrition. This study further suggest that the relationship between nutrition and socio-cultural system. epidmiological study of nutrition and cultural environment nutrition and conceptual characteristics, nutrition and food intake pattern, nutrition and health sociological functions and the physioloical, cultural and genetic adaptation can all be stimulating research subjects to be studied form and ecological point of view. This article also includes the results from a series of ecological studies conducted by the author investigating the relationship between nutritional status of Korean breast-feeding mothers and the composition of the human milk and also the Vitamin D status of Korean and their lifestyle.

  • The most favorable nitrogen source for the production of protease by Aspergillus oryzae PF was 2% soybean flour among sodium nitrate, ammonium sulfate, defatted soybean, skim milk, casein, peptone, and yeast extract. The production of protease from A. oryzae PF was higher at the concentration of 2% lactose than at variable concentration of glucose, sucrose, soluble starch, corn starch, potato starch, wheat starch, rice starch, cellulose, and gum arabic. Protease production was affected by the concentration of KH2PO4, Triton X-100, CaCo3, and MgSO4, and it was the highest at the highest at the concentration of 3% KH2PO4, 0.01% Triton X-100, 0.3% CaCO3, and 0.06% MGSO4.

  • For the manufacture of soybean cheese, curds were made from soy milk using either lactic starter or CaCl$_2$and ripened for 3 weeks. When papain was added during ripening, the amout of soluble protein increased. The yields of 3 soybean cheese were 76~88%, indicating that considerable loss of soy protein did not occur during the processing. During the period of ripening the change of moisture content was about 1 n. Total acidity of 3 soy cheese increased, demonstrating the production of lactic acid through lactic fermentation. Texture determined by Instron showed that 3 soy cheese had their own characteristic texture profile curve and that the cheese without papain treatment received the highest textural parameters. 3 manufactured soy cheese received 3-4 (good-very good) sensory scores in appearance, flavor and texture. General acceptibility of 3 cheese were evaluated as desirable or very desirable.

  • Few studies have conducted the bone health benefits of usual dietary isoflavone intake in Korean college-student women. To elucidate this benefitial effects and correlations between dietary isoflavone and nutrients intake and bone formation marker (ALPase, osteocalcin), questionnaires, anthropometric measurements, serum mineral (Ca, P, Mg) concentrations were analyzed. Fifty three subjects were used in this study. The average age, height, body weight, BMI, body fat content and triceps skinfold thickness were 21.43 year, 161.07 cm, 52.81 kg, 20.48 kg/$m^2$, 20.72% and 17.59 mm respectively. Soy food intake frequencies were soybean > soybean curd > soypaste stew > soybean milk. The average calorie, protein and Ca intake were 1766.21 $\pm62.54 kcal\;66.45\pm2.00 g\;and\; 549.62 \pm 27.55 mg$ respectively. Serum ALPase activity and osteocalcin concentration were 115.74$\pm3.6u/L$ and 7.15 ng/$m\\ell$ respectively. Usual dietary isoflavone intake was positively related to calory, protein, Ca, P intake and serum Ca, Mg concentration. Serum osteocalcin concentration was negatively correlated with isoflavone intake ($r^2$=0.28, p < 0.05). In these results, usual dietary isoflavone can support an additive effect to bone health and Ca nutrition.

  • Lactobacillus helveticus was inoculated to the fermentation liquid containing skin milk powder(SMT) plus soymilk, SMP plus isolated soybean protein(ISP), SMP plus ISP plus whey powder(WP) to increase the nutritional and economic value of commercial soy yogurt. The yogurt fermented with soymilk and SMP showed the lower acid production than of SMP and had significant beany flavor in the product. The yogurt prepared with ISP and SMP showed the higher cell number and lower acid production than that of SMP. Also, the partial substitution of SMP with ISP over 6%(w/w) produced less acceptable product due to gel production. The yogurt prepared by the partial substitution of SMP with ISP, WP and SMP showed the higher cell number and lower acid production than that of SMP and not bring about gel formation unlike the case of ISP. Sensory properties of yogurt substituted SMP with ISP and WP(38:62 mixture) below 4% were not significantly different from that of SMP and the sample containing the mixture over 6% and 0.067% artificial flavor showed lower sensory score due to beany taste than that of SMP. But increase of yogurt flavor up to 0.1% resulted in significantly high score in organoleptic acceptability. The separation of water occured in yogurt prepared by the combined mixture of ISP, WP and SMP, and this problem could be resolved by addition of Na-alginate and PGA at the concentration of 0.1%(w/w).

  • This study was conducted to evaluation the effects of dietary soybean meal (SBM) and fermented soybean meal (FSBM) on the growth performance of Korean native cattle as Hanwoo calves (Bos taurus coreanae) and Holstein cows. In total, 16 calves three to four months old (Control group, SBM: 5 males and 3 females, average weight 105.7 kg; Experimental group, FSBM: 5 males and 3 females, average weight 103.7 kg) were fed 5% of the feed amount for 53 days. In terms of growth performance outcomes, the average gain body weight was significantly higher in the FSBM group than in the SBM group in the final fattening period. The average daily gain in body weight (ADGBW) for the FSBM group was higher than that of the SBM group in the final fattening period. The average gain body weight in four months for FSBM was higher than that at three months in the final fattening period. Diarrhea incidence for FSBM was significantly decreased compared to that in the SBM group in the six-week period after weaning. These results indicate that dietary FSBM can improve the growth rate and health condition during the calving period. Holstein cows fed fermented soybean meal had higher milk urea nitrogen levels and decreased somatic cell counts compared to those fed SBM. These results may be closely related with the increased average daily gain body weight associated with dietary FSBM.
