The natural sources extracted from crab shell Korean tagnrine peel, sesame meals were utilized to investigate the effects of extracts on free radical reaction, lipid oxidation and nitrite scavenging ability. The recovery percentage of extracts from waste resources (crab shell, sesame meal, dry korean tangrine peel) were chitosan 11.6%, crude sesamol 2.2% and ascorbic acid 2.8%, respectively. The antioxidants were tended to have a lower TBARS value than those of control. The nitrite scavenging and electron donating ability of crude sesamol were tended to be the most effective extract among all extracts. However, In case of chitosan, the superoxide dismutase (SOD)-like activity was the most highest, compared to other extracts.

This study aims to provide basic data about the diversification and the development of sauces by making four kinds of Teriyaki sauce, and the findings are as follows. The satisfaction with Teriyaki sauce by age and cooking career and groups showed a significant difference in several items. According to the result of the preference analysis on professors and teachers, the preference for health/nutrition showed a significant difference; also, the result of the preference analysis on Teriyaki sauce ingredients among the culinary students showed a significant difference in awareness and health/nutrition. In addition, the result of the preference analysis on Teriyaki sauce ingredients among college students showed a significant difference in the order of taste, awareness, price, and health/nutrition. Lastly, the result of the preference analysis on Teriyaki sauce ingredients among all groups showed a significant difference in the order of awareness, price and health/nutrition. As the mindset that main ingredient of Teriyaki sauce is eel bone prevails and the sauce made by crab shells is highly preferred, sauces added with sea food products are considered to be possibly developed. The follow-up study will have to deal with a manufacturing method of sauce with high nutrition and economy efficiency resulting from cheap manufacturing unit price by making Teriyaki sauce with inedible but nutritions sea food products.

These studies were carried out to develop sausage using extracts from waste resources. The changes of pH and moisture contents were tended to be a similar to control, respectively ranged in pH 6.0~6.4 and 62~60% in moisture content. However, the water holding capacity of sausage added with chitosan and sesamol gradually were tended to be a little high, compared to control. The treatments using natural resource by-product revealed a low TBARS value, compared to control. This means that sausage added with natural by-product seem to be extend its shelf-life during storage. At the same time, the TBARS values were very similar to sausage added with 0.5% potassium sorbate. The residual nitrite contents of sausage added with natural resource by-product were tended to be a little lower than that of control. As storage time goes by, the nitrite contents of sausage product gradually were a little more decreased during storage at 3$0^{\circ}C$ than those of storage at 1$0^{\circ}C$. The lightness of sausage color gradually were a little more decreased during storage at 3$0^{\circ}C$ than those of storage at 1$0^{\circ}C$. The redness of sausage added with chitosan were a little highter, compared to control Sensory test suggested that the changes of sausage color, flavor, texture and taste were tended to be decreased gradually. In conclusion, sausage added with natural resource by-product was effective on the basis of the reduction in residual nitrite content and lipid oxidation.
