  • Purpose: To improve the cooking quality of brown rice, newly inbred soft rice cultivars were investigated. Methods: The physicochemical properties of brown rice flour and water absorption patterns and cooking characteristics of brown rice grain were compared to Ilmi white and brown rice. Results: General composition and total dietary fiber contents of five rices were significantly different with higher ash, protein, and total dietary fiber contents in soft brown rice than white rice. The hardness of raw rice grain was higher in Ilmi brown rice than in soft brown rice. The water absorption increased rapidly in 30 min of white rice and in 4-6 h of brown rices. The apparent amylose content of soft brown rice was lower than that of Ilmi rice. The initial pasting temperature and all viscosities were significantly different, but the trend was not similar. The textural properties of hardness and roughness were higher, but adhesiveness, cohesiveness, and stickiness were lower in Ilmi brown rice than white and soft brown rices. In sensory preference test, not only textural properties, hardness, adhesiveness, cohesiveness, stickiness, and roughness, but also color, glossiness, and roasted flavor were higher in soft brown rices. Especially soft brown rice B showed the best cooking quality among all rices. Conclusion: The results of the study suggested that soft brown rice is developed for cooking with high nutritional and functional quality.

  • Cabbage is a biennial plant that is native to the shores of the Mediterranean. It contains dietary fiber, minerals, vitamin A, vitamin C, and anticarcinogenic phytochemicals. For the test, cabbage powder was added (5%, 10%, 20%, and 30%) to flour. The addition of cabbage powder significantly increased the specific gravity and viscosity of the batter and pH of both the batter and chiffon cake. The moisture in the chiffon cake increased due to the addition of cabbage powder. Also, the lightness of the cake significantly increased, whereas the redness and yellowness decreased as the amount of cabbage powder increased. The lightness and redness of crumbs from C0 were higher than other samples as each 59.48, -3.17, respectively. Except for the resilience, the hardness, gumminess, fracturability, and adhesiveness showed similar values in the C0, C5, and C10. In terms of consumer perception, the color, softness, flavor and overall consumer preference for the control chiffon cake were higher than C5, C10, C20, and C30. Nonetheless, for those that contain cabbage powder, C5 and C10 had relatively higher consumer preferences than C20 and C30. As a result, the optimum amount of cabbage powder for the chiffon cake would be from 5~10%.

  • Recently the demand for wool has been gradually decreasing due to global warming, oil depletion, Coolbiz campaign to reduce CO2 emission, and preference for business casual wear, while the price for wool materials has been constantly increasing. Wool, characterized by the natural touch and unique sensibility, is considered as one of the best natural materials, including silk. For wool, currently Korea almost depends on import from foreign countries. Therefore, 100% wool products cannot be competitive in terms of pricing and current trend. To secure sustaining competitiveness in the fiber market, it is required not only to develop new wool materials that enable expression of new sensibility that cannot be expressed by conventional wool fibers, but also to pursue differentiation of fundamental sensibility and functionality by highlighting advantages for wool as a natural fiber but by reducing its disadvantages through dominant conjugation with synthetic fibers. This study attempted to improve the technology of differentiating wool-like synthetic fibers such as polyester and combine technology with sensibility through mixing with wool materials. It also aimed to develop wool-like stretch materials and pre-treating and yarn dyeing technologies that enable fabrics to main natural wool-like touch and stretch, and ultimately to develop wool mixed fabrics that have new sensibility and functionality.

  • This study was designed to characterize the physicochemical effects of the addition of rice wine cake(0, 1, 2, 4%) to yackwa. Dietary fiber, volume, SEM, TBA, color, texture characteristics and sensory evaluation of yackwa were investigated. The dietary fiber content of rice wine cake was 10.24%, and the dietary fiber content of yackwa increased with added rice wine cake. The extensibility value increased with more rice wine cake. SEM revealed, many holes in a delicate structure with many layers. During a 4-week storage period, yackwa containing rice wine cake had lower TBA values than control, except for the sample containing 4% rice wine cake. The TBA value of yackwa containing 4% rice wine cake had the highest TBA value. The L value and b value of samples decreased with the addition of rice wine cake and storage time, but the value increased with added rice wine cake according to the storage time. The hardness, cohesiveness and gumminess of yackwa increased according to the time of storage and the addition of rice wine cake, but the springiness and chewiness of yackwa decreased. In sensory evaluations, all items received the lower scores according to the storage time. Yackwa that contained 1%(RWC1) received the highest score for color and flavor, and yackwa that contained 2% (RWC2) had the highest score for crispness and roast. Overall preference was, in order: RWC2 > RWC1 > CON > RWC4. Yackwa that contained $1{\sim}2%$ rice wine cake possessed superior features in most of the quality properties and in sensory evaluation, so yackwa that contains rice wine cake can be used as a functional food.

  • The physicochemical, sensory, and functional properties of Codonopsis (C.) lanceolata tea with different amounts of sugar (25%, 50%, 75%, and 100%) were investigated. There were no significant changes in crude protein, crude fat, and ash contents of C. lanceolata tea with different amounts of sugar. In contrast, carbohydrates decreased and moisture content increased in C. lanceolata tea with different amounts of sugar. The natural presumption is that carbohydrates increase with increasing amounts of sugar. In terms of color, the L-value decreased and the b-value increased with increasing amounts of sugar. Although there were no significant changes in total dietary fiber, soluble dietary fiber increased and insoluble dietary fiber decreased with increasing amounts of sugar. The total phenolic and flavonoid content increased, while saponin content remained constant with increasing amounts of sugar. The highest overall acceptability values in the sensory test for color, flavor, taste, and overall preference were 5.77, 5.82, 5.72, and 5.95, respectively, with the addition of 75% sugar.

  • The purpose of this study was to investigate the compliance and need for diet therapy among diabetics and their caregivers. A total of 625 respondents participated in this survey. Appropriate management for long-term blood glucose control and difficult-to-manage cases appeared to be diet therapy, physical activity, medical treatment and folk remedies, in that order. The most important educational avenues for diet therapy were books, magazines and TV, Most respondents were educated in diet therapy within a year after diagnosis and had practiced diet therapy for over four years. The most common diet therapy Practices were food selection and Quantity control. Of the specific problems in practicing diet therapy, time and labor, taste, and meal planning appeared to be equally difficult factors. The prevailing diet therapy skills were controlling food amounts at breakfast and supper, and selecting food for lunch and refreshments. Respondents practicing both skills were about 20% of the participants; this shows the need to improve the current situation. The nutrients most frequently considered in diet therapy practice were simple sugars (sugar and sweet goods) , total fats and cholesterol. Since the perception of the role of dietary fiber among respondents was very low, nutrition education about the importance of dietary fiber and food sources of dietary fiber was needed. Diabetics seemed to be concerned about diabetic menus. Three difficult problems in planning diabetic menus were daily menu planning, patient's preferences, and the calculation of calories. As a means of nutrition counseling, they preferred interviews. The higher the educational status and the lower the age, the higher the preference was for internet or PC counseling. Therefore, it is necessary to develop nutrition educational programs so that diabetics can obtain practical knowledge of diet therapy. Furthermore, it is also necessary to develop additional means of informing diabetics about menu planning, while still considering Korean dietary behavior.
