  • Evaluation of soy milk as an iron-rich milk substitute was conducted by feeding commercial soy milk , cow milk and mixed formula(soy and cow milk) to Wistar rats for 8 weeks. Body weight gains were significantly lower in the soy milk and mixed formula groups. Hematocrit, serum iron concentration and TIBC (total iron binding capacity) were measured to determine the iron status of the rats. In these respects, the iron status of the soy milk group was normal. Both serum iron concentration and TIBC as well as hematocrit were abnormal in the cow milk group , which is indictive of severe iron deficiency . Although hematocrit was normal in the mixed formula group, serum iron concentration was lightly low. The work capacities of each group were correlated with serum iron concentration and tIBC rather than hematocrit. The running distance of the soy milk group was about 10 -fold longer than that of the cow milk group. Soy milk may be considered an iron- rich substitute for cow milk due to its higher iron content and bioavailability.

  • This study tested the development of bechamel sauce with different ratios of soy milk to milk(0:4, 1:3, 1:1, 3:1, 4:0) to examine changes in quality characteristics. Proximate composition analysis showed a decrease in salinity with increasing amounts of soy milk, while the moisture content and, density increases. The highest pH values were found for a 1:1 ratio of soy milk to milk (S2) and the lowest pH values were found for a 0:4 ratio of soy milk to milk (CON). The L-value decreased, while a and b values increased with increasing amounts of soy milk. In the stability test, segregation occurred in CON after 5 days, while the highest segregation occurred at a 4:0 ratio of soy milk to milk (S4). The sensory evaluation results showed that the color, thickness, savory flavor, and savory taste increased with increasing amounts of soy milk. In the acceptance test, a 1:3 ratio of soy milk to milk (S1) and a 1:1 ratio of soy milk to milk (S2) had the highest acceptance scores (p<0.001) for appearance, taste, texture, and overall acceptance.

  • The objective of this study was to develop yogurt-cheese using cow’s milk, ultrafiltrated cow’s milk, and soy milk. The addition of soy milk and ultrafiltrated milk increased the amount of protein in the yogurt-cheese. Yogurt-cheeses were made using cheese base using 10% and 20% soy milk with raw and ultrafiltrated cow’s milk, and stored at 4°C during 2 wk. The yield of yogurt-cheeses made with added soy milk was decreased and the cutting point was delayed compared to yogurt-cheese made without soy milk. Yogurt-cheese made using ultrafiltrated cow’s milk showed the highest yield. However, yogurt-cheese made with added soy milk had higher protein content and titratable acidity than yogurt-cheese made using raw and ultrafiltrated cow’s milk. Fat and lactose contents in the yogurt-cheese made with added soy milk were lower. Yogurt-cheeses made with added soy milk contained several soy protein bands corresponding to the sizes of α2-, β-, and κ-casein band. Yogurt-cheese made with added soy milk had similar elasticity to yogurt-cheese made without soy milk but had lower cohesiveness. There was no significant difference in the number of lactic acid bacteria in the different cheeses, as all had over 8.0 Log CFU/g. Considering these data and the fact that proteins and fats of vegetable origin with high biological value were observed as well as unsaturated fats, yogurt-cheese made with added soy milk can be considered to be a functional food.

  • The purpose of this study was to determine if Theory of Planned Behavior (TPB) variables predict soy milk intake in a sample of WIC participants in 2 Illinois counties (n = 380). A cross-sectional survey was used, which examined soy foods intake, behavioral beliefs, subjective norms, motivation, and intention. Soy product intake was low at both sites, and many participants (40%) did not know that soy milk was WIC approved. Most (> 70%) wanted to comply with their health care providers, but didn't know their opinions about soy milk (50-66%). Intention was significantly correlated with intake (0.507, P ${\leq}$ 0.01; 0.308, P ${\leq}$ 0.05). Environmental beliefs (0.282 and 0.410, P ${\leq}$ 0.01) and expectancy beliefs (0.490 and 0.636, P ${\leq}$ 0.01) were correlated with intention. At site 1, 30% of the variance in intention to consume soy milk was explained by expectancy beliefs and subjective norm beliefs (P < 0.0001); at site 2, 40% of the variance in intention was explained by expectancy beliefs. The TPB variables of expectancy beliefs predicted intention to consume soy milk in WIC participants. Therefore, knowing more about the health benefits of soy and how to cook with soy milk would increase WIC participants' intention to consume soy milk. Positive messages about soy milk from health care providers could influence intake.

  • Tom coagulated with $CaCl_2$ was used to make high-Ca soy milk, named tofu milk. Physicochemical analysis of regular soy milk and tofu milk adjusted at various pH and/or heat-treated was carried out. Unheated and heat treated tofu milk kept stable conoldal state at pH 8. The solubility of soy milk was low at pH 4 but increased gradually at higher pH, while mat of tofu milk was almost unchanged between pH 4 and pH 7 but increased rapid1y above pH 8. At pH 8, the viscosity of tofu milk was almost the same as soy milk, while mat of heat-heated tofu milk was much higher man that of soy milk. Especially, steamed tofu milk seemed to be a thick paste unable to drink, but autoclaved tofu milk was suitable to drink. Phytic acid content of tofu milk was somewhat lower man mat of soy milk.

  • Dairy products are important diet source for human because of their balanced essential nutrients along with various vitamins and minerals. However, lactose in milk can result in diarrhea to some consumers with lactose intolerance. Soy milk has no lactose and is suitable as a substitute for diary milk in accordance with recent trend of replacing animal food with vegetable food. However, polysaccharides in soy milks are difficult for humans to digest, leading to flatulence. These polysaccharides can be decomposed into monosaccharides by lactic acid bacteria, and fermentation can improve food quality. Because mungbean has higher carbohydrate content than soybean, mung milk can be easily fermented than soy milk, resulting in vege yogurt with higher contents of lactic acid. In this study, fermentation characteristics of vege yogurt were analyzed with different ratio of soy milk and mung milk (0%, 25%, 50%, 75%, 100% and 0%+sucrose) and different fermentation time (0, 8, and 16 hours). In general, pH decreased as fermentation time increased. Overall, pH significantly decreased when the mung milk content in yogurt increased. All samples showed higher titratable acidity after fermentation and soy yogurt (mungbean 0%, 16 hours) with sucrose showed the highest value (6.825%). As fermentation time increase, viscosity increased. In 8 and 16 hours, mung milk yogurt (mungbean 100%) showed the lowest viscosity while soy milk yogurt (soybean 100%) with no sucrose showed the highest viscosity after 16 hours of fermentation. The contents of crude protein, crude fat and ash were measured for nutritional analysis. Soy milk (mungbean 0%, 0 hours) had the values of crude protein 2.9g, crude fat 1.8g, and ash 0.3g, and mung milk (mungbean 100%, 0 hours), showed the values of crude protein 1.7g, crude fat 0g, and ash 0.3g. To analyze the effect of the differences in the contents of nutrition between soy milk and mung milk on fermentation, the changes in sugar contents, and antioxidant capacity will be conducted depending on fermentation time. Our results will provide the information in researching plant beverages.

  • Objective: Soy sauce oil, a byproduct of whole soybean processing by the soy sauce industry, was evaluated as a source of linoleic acid for dairy cows for the purpose of manipulating the composition of milk. Methods: Eight dairy Holstein cows fitted with rumen cannulas were used for ruminal administration of soy sauce oil for a 28-day period using a 4×4 Latin square study design with 4 doses (0, 200, 400, and 600 g soy sauce oil/d). Results: Although dry matter intake and milk yield were not affected by soy sauce oil administration, ruminal concentrations of total volatile fatty acids and acetate were decreased, specifically at 600 g/d administration. While milk fat percentage was decreased with administration of soy sauce oil, proportions of linoleic, vaccenic and conjugated linoleic acids in the rumen, blood and milk were increased with increasing soy sauce oil dose. Conclusion: These results suggest that soy sauce oil feeding could be useful for improving milk functionality without adverse effects on animal production performance when fed at less than 400 g/d.
