Physicochemical properties and storage stability of plant-based alternative meat prepared with low-fat soybean powder (LPAM) treated by supercritical-CO₂ and those of full-fat soybean powder (FPAM) were compared. Ash and crude protein contents were higher in LPAM than in FRAM. Water absorption capacity and oil absorption capacity were significantly higher in LPAM than in FPAM. Water binding capacity was higher in LPAM than in FPAM during a 20 days storage period at 5℃ and pH was significantly lower in LPAM than in FPAM after a 5~10 days storage period. Hardness, gumminess and chewiness significantly increased with the increase in the storage period, and the three were significantly higher in LPAM than in FPAM after 10 days and 20 days of storage. The acid value showed no remarkable difference according to the storage period in LPAM; however, it was significantly higher in FPAM than in LPAM after 20 days of storage. The peroxide value and TBA value were significantly increased according to the storage period, and were significantly lower iin LPAM than in FPAM during all the storage periods. Therefore, the use of low-fat soybean powder may be effective in improving oxidative stability during storage in the production of plant-based alternative meat.

Among the many foods, it is hard to find perfect food with nutrition and functionality like beans. Korean food culture is the main ingredient of korean culture, kochujang, soybean paste, and soy sauce, and processed soybean tofu is the main ingredient. Soybean meets high quality protein and fat, and it has excellent results in prevention and treatment of all kinds of diseases. Soybean food is becoming a new generation health food. In countries where animal protein intake is low, soybean is used as a protein source instead of animal protein. Tofu, a processed food, is a complete food with high digestibility. In order to publicize the superiority of soybean nutritional value, Tofu processing and powder were investigated by observing the size, shape and characteristics of bean powder using domestic soybeans and imported soybean, and the variation of the amount of coagulant.

In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated. The levels of daidzein and genistein were $149.28{\mu}g/g$ and $364.31{\mu}g/g$, respectively. After six weeks experimental period, Food efficiency ratio in the 10 and 20 BTS group was significantly lower than the HF group (P<0.05). Total serum levels of cholesterol, triglycerides, low-density lipoprotein cholesterol, and atherogenic index ratio in the 10 or 20 BTS group were significantly lower than the HF group. The levels of alanine aminotransferase, aspartate aminotransferase and thiobarbituric acid reactive substance were significantly lower in the groups that received 10% and 20% BTS than the HF. The activities of SOD and CAT were significantly higher in the 10 and 20 BTS group than the HF group. The activity of XO in the 10 and 20 BTS group was significantly lower than in the HF group by 20% and 23%, respectively. In conclusion, these data suggest that BTS is an effective agent in improving lipid metabolism and antioxidant enzyme system.

Sodium chloride plays an important role as the main condiment at daily meal. It is well known that humans require sodium chloride as an essential nutrient to keep the homeostasis of electrolytes. The amounts of salt intake may be a reflection of geography, culture and food habit rather than necessity. Lee has reported (1962) that Koreans ingest high amounts of sodium chloride in their meals, with an intake of excess carbohydrate (80-90% of total Calories) and low protein in their diet. This includes large amounts of rice, Kimchi and other fermented soybean products common in the Korean diet. This investigation was designed to study the dietary relations of sodium chloride to other nutrients in the Korean diet. Twenty four albino male rats, weighing from 290-300g, were divided into four dietary groups according to the amounts of carbohydrate, protein and fat in the basal diet. Each diet contained a rice powder as a carbohydrate source. Diet I was a control diet, Diet II, low protein, Diet III, low protein and low fat diet and Diet IV, low fat diet. All rats were provided with 3% sodium chloride solution. Diet and salt solution were given ad libitum. The experiment was carried out for 9 weeks during which time the body weight, the food intake, and 3% sodium chloride solution consumption were determined. At the 9th week, the urine was collected the blood sample from the artery of each rat for the analysis of sodium and potassium and other chemical studies. The rats were sacrificed and the kidney, adrenal, liver and spleen were measured, and observed changes of the pathological tissue in the kidney and adrenal. The results were summarized as follows: 1) The growth rate was higher in Diet I than in the other experimental diets (II, III and IV) after 4 weeks. There was no significant difference found between the experimental Diets II, III and IV. 2) The daily food intake was greater in the experimental diets II, III and IV than in the control diet. However, there was no difference among the high carbohydrate diets Diet II, III and IV. 3) The daily water (3% sodium chloride solution) intake was also greater in the Diets II, III and IV, than in the control diet. However, there was no difference between Diets II, III and IV. 4) The concentration of sodium and potassium in the blood were within the normal range in all diets. 5) The amount of sodium chloride in the urine was significantly greater in Diets II, III and IV than in the control diet. Diets II, III, IV had a larger amount of sodium solution consumption. 6) Observation of pathological tissue in the experimental diets found a cell proliferation in the glomerlulus of the kidney, while such change was not found in the control diet.

The objectives of this study were to investigate the antihyperglycemic and hypolipidmic effects of sea oak(Eisenia bicyclis, EB) in the diabetic state and to examine the appropriateness of formulated EB pill for the effects. The various test materials obtained from EB were included in the experimental diets with 15% fat/0.5% cholesterol and fed to streptozotocin-induced diabetic mice weighing $35.0{\pm}0.7$ g for three weeks but not in the control diet having the same composition. The test materials were EB dry powder, water and ethanol extracts, viscozyme-treated EB water extract(EB enzyme-TR) and formulated pill containing dry powders of the EB, two kinds of seaweed, black soybean, sesame, onion and garlic. BG was measured during feeding period and serum insulin, lipids and thiobarbituric acid reactive substances(TBARS) and intestinal disaccharidase activities were measured at the end of the three weeks of the feeding. BG increase was lower in the EB enzyme-TR group after 10 days of the experimental diet but lower in EB pill group after 15 days compared with the control group. Serum insulin levels were higher in the EB enzyme-TR and EB pill groups. Intestinal maltase but not sucrase activity was higher in EB enzyme-TR fed group than the control group. Serum levels of total cholesterol and triglyceride were reduced by the EB enzyme-TR and EB pill compared with the control diet. HDL-/total cholesterol was increased by all EB test materials. Serum TBARS levels were lower in the EB ethanol extract and EB pill groups than in the control group and tended to be lower in the other EB groups. It is concluded that the EB enzyme-TR is the best among the EB preparations to be utilized as a functional component for improving blood glucose and lipid profile in diabetic subjects in the future. However, the pill containing low level of the EB powder is also regarded as effective and readily usable when formulated with the several other ingredients of the proper composition.(Supported by the RIC Program of MOCIE, Korea).
