  • Protein is a major nutrient of food and has long been studied for nutritional and utility value. Among them, rice protein is attracting attention because of its hypoallergenic characteristics and nutritional value. Rice proteins are divided into endosperm protein and bran protein depending on their location. The two proteins differ in their nutritional characteristics and applications. The endosperm protein is an insoluble protein and has an advantage of digestion and absorption. Rice bran protein dissolves well in water. Its amino acid value is high enough to be comparable to that of soy protein, and it has strong antioxidant ability. Rice protein is a healthy vegetable protein because of its health and hypoallergenic properties. It has been widely used in children's or patients' food, and recently for muscle supplement and health food. Rice protein is considered to be a very effective and useful material as it has been discovered so far.

  • To confirm the food quality and storage stability of commercial Korean kamaboko, we experimented with the composition and textural properties using various surimis and kamaboko products. We also investigated changes in protein digestibility and lipid oxidation of vacuum packed products under chilled storage at $4{\pm}1^{\circ}C$. Among the fish meatbased surimi, vegetable mixed surimi had the lowest protein content (23.73 %), as compared to other surimi (51.9-73.6%). Siginificant (P<0.05) differences in protein, lipid content and degree of fat oxidation were noted between the fried kamaboko products of three companies. Adhesiveness, springiness, cohesiveness, gumminess, chewiness and resilience were similar in all samples, but there were notable differences in hardness and fractuability between samples. In vitro protein digestibility and trypsin indigestible substrate (TIS) were not inversely proportional in fried kamaboko products. The protein digestibility (80.30%) of steamed vegetable mixed fried kamaboko was lower than that of other fried samples (84.9-86.2%). Computed protein efficiency ratio (C-PER) of companies A and C's fried kamaboko was 2.6 but company B's was 1.9. There was no noticeable change in thiobarbituric acid reactive substances (TBARs) or protein digestibility for any of the vacuum packed fried kamaboko during 30 days of chilled storage.

  • This study aimed to identify the effect of brown rice-vegetable school meals program on the subjective health status, BMI and hematological parameters of high school students. This is a single group pre-post study design that includes 17 high school boys and 18 high school girls. Students were catered for lunch and dinner with brown rice and a vegetarian diet for 12 weeks at the school. The collected data on subjective health status, BMI levels and hematological parameters were measured in pre and post, and changes were compared by paired t-test. Subjective health status of the participants has improved and BMI was reduced. Blood Hct, Hb, Hct, total protein and albumin have also been reduced. Ca and triglyceride levels decreased in females. However, all levels were reduced within the normal range. These results show that brown rice-vegetable intake of high school students reduces weight and helps them prevent from acquiring cardiovascular diseases in adulthood through the reduction of serum triglyceride and in practicing healthy eating habits.

  • This study was conducted to evaluate the quality properties of emulsion-type pork sausages when pork fat is replaced with vegetable oil mixtures during processing. Pork sausages were processed under six treatment conditions: T1 (20% pork fat), T2 (10% pork fat + 2% grape seed oil + 4% olive oil + 4% canola oil), T3 (4% grape seed oil + 16% canola oil), T4 (4% grape seed oil + 4% olive oil + 12% canola oil), T5 (4% grape seed oil + 8% olive oil + 8% canola oil), and T6 (4% grape seed oil + 12% olive oil + 4% canola oil). Proximate analysis showed significant (p<0.05) differences in the moisture, protein, and fat content among the emulsion-type pork sausages. Furthermore, replacement with vegetable oil mixtures significantly decreased the ash content (p<0.05), increased water-holding capacity in emulsion-type pork sausages. Also, cholesterol content in T6 was significantly lower than T2 (p<0.05). In the texture profile analysis, hardness and chewiness of emulsion-type pork sausages were significantly (p<0.05) decreased by vegetable oil mixtures replacement. On the contrary, cohesiveness and springiness in the T4 group were similar to those of group T1. The unsaturated fatty acid content in emulsion-type pork sausages was increased by vegetable oil mixtures replacement. Replacement of pork fat with mixed vegetable oils had no negative effects on the quality properties of emulsion-type pork sausages, and due to its reduced saturated fatty acid composition, the product had the quality characteristics of the healthy meat products desired by consumers.

  • This retrospective study was designed to evaluate the nutrient contributions of the five meal components of school lunch menus planned for elementary students in two school districts (District A and B) in the Midwestern state of the United States. The 4-week cycle menu was planned for two time periods (Period 1 and Period 2) following guidelines for NuMenus and general menu planning principles. Menu components of planned and served menus for two time periods were analyzed using $Nutri-Kids^{TM}$. No significant differences in the nutrient content of between Periods 1 and 2 were found for District A. District B served significantly more vitamin A and total fat in Period 1 and significantly more calories, iron, vitamin A, protein, and total fat in Period 2 than was planned. The major nutrients provided by the entree component included protein, calories, cholesterol, total fat, saturated fat, and sodium. Milk was an important source of calcium and provided approximately one-third of the total protein and vitamin A in the meal. The vegetable/fruit component was the major source of vitamins A and C. The grain/bread component provided approximately 20% of the carbohydrates among five meal components. The miscellaneous component affected the sodium and fat content of the menus. Menu planners can use the results of this study to enhance their knowledge of the nutrient contributions of each meal component and as inputs for planning menus that meet children's nutritional requirements.

  • This study analyzed the quality of texturized vegetable protein (TVP) made from defatted soy flour combined with flour or starch from rice sources. The base raw material formulation consisted of 50% soybean protein, 30% gluten, and 20% rice flour and rice starch. A cooling die-equipped extruder was used with a barrel temperature of 190℃ and screw rotation speed of 250 rpm. The hardness and cutting strength of the extruded TVP were found to be higher for white rice than for glutinous rice and higher for flour than for starch. Gumminess and chewiness were similar across rice types, but higher for flour than for starch. White rice TVP had a lower water absorption capacity than glutinous rice TVP. Turbidity was lowest for white rice flour and highest for corn starch. Using rice flour instead of starch in TVP production can simplify processing and contribute to promoting the consumption of rice.
