We analyzed the ${\gamma}$-aminobutyric acid (GABA) content of a selection of uncooked foods. Foods with GABA concentrations in excess of 100 nmole per g dry weight included: brown rice germ, brown rice sprouts, barley sprouts, bean sprouts, beans, corn, barley, brown rice, spinach, potatoes, sweet potatoes, yams, kale and chestnuts. Cereals included: brown rice germ, brown rice sprouts, barley sprouts, bean sprouts, beans, corn, barley, and brown rice and had GABA concentrations of 718, 389, 326, 302, 250, 199, 190, and 123 nmole per g dry weight (DW), respectively. The vegetables: spinach, potatoes, sweet potatoes, yams and kale contained 414, 166, 137, 129, 122 nmole GABA per g DW, respectively. The GABA concentration of chestnut was 188 nmole per g DW. However, oatmeal, adlay, broccoli, squash, carrots, onion, apples, lentinus edodes, green laver, and lactobacillus had GABA concentrations of less than 100 nmole per g DW. These results show that brown rice germ, sprouted cereals and spinach are good sources of plant-derived GABA. These data will be useful in selecting foods for the manufacturing of uncooked foods containing a relatively high concentrations of GABA.

Uncooked rice Tackju was prepared from the groud rice with different particle size such as 12, 20, 35 and 50 mesh, and its characteristics were analysed during the brewing. Reducing sugar and ethanol contents as well as yeast cell counts were the highest in main mash and Tackju prepared from 20 mesh fraction. Especially, reducing sugar content was about. 1.5-2.5 times as much as that obtained from 35 or 50 mesh fraction. The final concentration of ethanol in main mash prepared from 20 mesh fraction was 14.8%(v/v). It was about 1.5%(v/v) higher than the lowest one [13.35%(v/v)] which was prepared from 12 mesh fraction. No significant difference In total acidity was observed. Sensory evaluation revealed 20 or 35 mesh Tackju to be the best in overall preference, especially in sweet and refreshing tastes.

This study was conducted to investigate the effect of an uncooked powdered food(UPF) on the weight loss and changes of the biochemical nutritional status for 20 overweight and 26 obese women in Iksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Also anthropometric and biochemical measurements before and after the UPF program were estimated. The intake of energy, lipid and protein decreased and the quality of meals improved as people started to take UPF. Due to the energy loss by taking UPF, weight and body fat decreased significantly. The percentage of the body fat was high among the weight lost, from which we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening the body fat. The most positive change among biochemical changes by taking UPF was the decrease of serum lipid contents. When overweight and obesity women replaced two out of three meals with UPF for 3 month period, no significant nutritional problems occurred. It seems that the 12weeks of UPF program used in this study was effective in improving anthropometric indices without producing the deficiency of iron or other susceptible nutrients.

This study was designed to investigate the effects of weight reduction and changes in serum lipid composition using a commercial uncooked powdered food (UPF) diet on 27 obese hyperlipidemic women over a period of 12 weeks. We replaced the standard breakfast and dinner of each of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using a body fat analyzer. Also, we conducted hematological, clinical and lipid profile analyses of their blood. Their intake of energy, lipid and protein significantly decreased as the subjects started to take UPF, but their intake of vitamins and minerals, other than iron, increased. Due to the energy intake decrease, the subjects' weight, body fat and waist circumference significantly decreased. Among the lost weight the percentage of the body fat was high. We judged that this process of losing weight was successful in obese hyperlipidemic women. Serum HDL-cholesterol gradually increased and serum total-cholesterol, LDL-cholesterol, triglyceride levels showed gradual decreases. When obese hyperlipidemic women replaced two of three meals with UPF for 3 months, we were able to see useful changes like decreased body fat and serum lipid. Complete judgment on the usefulness of UPF may be difficult but if people take a standard meal once a day and replenish their iron by taking UPF twice a day, we assume that replacing UPF with balanced regular meal not be a problem in nutritional status. Our results show that UPF is effective in the diet therapy of obese hyperlipidemic women.

Purpose: In this study, small black beans (Rhynchosia nulubilis) that were produced in the Jungsun province of South Korea were selected for use in various cooking recipes because they are known to contain higher isoflavones and excellent antioxidant effects, as compared to any other domestic soybeans. Methods: Physicochemical and antioxidant characteristics of small black beans were analyzed with uncooked beans and four other cooking methods of pan broiling, boiling, steaming, and pressure cooking. Results: Contents of ${\beta}$-glucosides (daidzin, glycitin, and genistin) and aglycone (daidzein, glycitein, and genistein) in small black beans were significantly different depending on the cooking methods (p<0.001). The results of the experiment indicated that the amount of total polyphenol in pressure cooked beans was highest, showing a value of 7.16 mg/g (p<0.001). Most contents of isoflavones (${\beta}$-glucoside, aglycone) in uncooked beans appeared to increase after cooking. In particular, the amount of glycitein was highest in pan broiled beans ($9.63{\mu}g/g$). The total isoflavone content differed among the different cooking methods, ranging from highest to lowest in the following order : pan broiled beans ($759.49{\mu}g/g$), pressure cooked beans ($725.12{\mu}g/g$), boiled beans ($591.05{\mu}g/g$), steamed beans ($511.61{\mu}g/g$), and uncooked beans ($180.80{\mu}g/g$) (p<0.001). Conclusion: Especially, the amount of isoflavones increased significantly in pan broiled beans and pressure cooked beans, suggestive of optimized cooking methods for increasing nutritional and functional contents in cooked food.

The objective of this study was to improve the qualities of Saengsik (substitute meal formulated with uncooked cereal powder) such as functionality, safety and sensory preference by using Lactic Acid Bacteria (LAB). The optimum formulation of fermented Saengsik (substitute meal) was verified as $40\%$ of fermented brown rice, $13\%$ of fermented job tears, $5\%$ of yellow soybean, $5\%$ of waxy rice, $5\%$ of sorghum, $3\%$ of Seumok bean, $1\%$ of sesame, $3\%$ of barley, $2\%$ of red bean, $5\%$ of prosomillet, $2\%$ of foxtail millet, $9%$ of black rice, $3\%$ of buckwheat, $1\%$ of chestnut, $2\%$ of pumpkin, $3\%$ of peanut. Fermented Saengsik decreased significantly serum glucose in STZ-induced diabetic rats. However, serum lipid levels were not affected by fermented Saengsik. In rats fed with high-fat diet, serum triglyceride level was slightly decreased and the contents of liver triglyceride were significantly decreased by supplementation of fermented Saengsik.

The purpose of this study was to obtain the nutritional values and objective data of uncooked powdered food (UPF) in korea. We interviewed 27 healthy female subjects aged over 25 years living in the lksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using body fat analyzer. Also we conducted hematological and clinical analysis of blood. The intake of energy, lipid and protein has decreased as people started to take UPF, but the intake of vitamins and minerals has increased. The quality of meals has improved after taking UPF. Due to the energy loss by taking UPF, weight and body fat gradually lessened. Among the lost weight the percentage of the body fat was high and we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening body fat. The most positive change among biochemical changes by taking UPF was decreasing of serum lipid contents. The concentrations of total cholesterol and LDL-cholesterol gradually decreased and decreased intently after 12weeks. Serum HDL-cholesterol gradually increased and serum triglyceride showed gradual decrement. When healthy adult women replaced two of three meals with UPF for 3months, we were able to see some useful changes like decrement of body fat and serum lipid control and during this 3month period, no significant nutritional problems occurred. Complete judgement on UPF may be difficult with these conclusions but if people take a nomal meal once and replenish iron from taking UPF twice a day, we assume that replacing UPF with regular meal not be a problem in nutritional status. If other experiments on the effects of UPF proceed, we believe that those experiments will be very helpful in judging the nutritional value of UPF. (Korean J Nutrition 36(1) : 49-63, 2003)
