This study was conducted to investigate the quality characteristics of Yanggaeng prepared with different concentrations of mealworm powder: 0, 1, 2, and 3%. Regarding the proximate composition, moisture, crude lipid and ash contents showed no significant differences among groups, while crude protein contents increased as the mealworm powder increased. The value of lightness (L) and yellowness (b) were higher in 3% added groups than those of control groups. Consumer acceptance test showed no significant differences between the controls and added groups were observed in color, smell, taste and overall acceptability. The total polyphenol content ranged from 19.87 to 51.37 mg GAE/100 g, exhibiting the increase with increasing mealworm powder level. DPPH radical scavenging activity and reducing power increased as the amount of mealworm powder increased. In conclusion, it is suggested that mealworm powder can be incorporated into Yanggaeng up to 3% without affecting the sensory quality of Yanggaeng.

In this study, rice candy was produced with mulberry leaf and its effect on the lowering blood glucose level was assessed. The results were as follows: The recovery rate of mulberry leaf powder was 32.7%. The contents of crude protein, lipid, ash and crude fiber of mulberry leaf were 19.54%, 4.82%, 12.80%, and 11.27%, respectively. The sensory evaluation revealed that the rice candy added with 1% mulberry leaf powder showed slightly hi인or palatability score than that of 2%, but we decided that 2% addition of mulberry leaf powder would be preferred over 1% if considering both the physiological function and the sensory acceptability. The blood glucose level after ingesting the rice candy with mulberry leaf lowered by 31%, more than that of control.

To obtain basic information for the quality evaluation, the introduced or domestic sesame seeds were investigated to measure proximate components (crude protein, ash, mineral and oil) and isolated by preparative HPLC system for lignan contents. Although crude protein contents were the highest in Sudan sesame seeds, lipid, ash and mineral contents were not significantly(p<0.05) different between introduced and domestric sesame seeds. Unsaturated fatty acids such as oleic and linoleic acids were the highest in the domestic sesame seeds. The Mg content of domestic sesame seeds also was larger than that of introduced sesame seeds. A Ca content of domestic sesame seeds, however, was significantly (p<0.05) lower than that of China. Lignan contents, the most important component known as antioxidant, were significantly (p<0.05) higher in domestic sesame seeds than other sesame seeds tested. Our findings suggest that domestic sesame seed has the best quality in terms of the functional components.

We previously reported the antimutagenicity, anti-lipid peroxidation and antiinflammtory properties of the three Chinese herb medicine, Kalopanax pictus, Pueraria thunbergiana and Rhus verniciflua, which have been used as therapeutics for diabetes mellitus and inflammation in Korea. Since these drugs have been used for the prescriptions consisted of several crude drugs, we investigated whether the extract of the three drugs could increase the individual drugs or not. The three extracts were independently prepared from K. pictus, P. thunbergiana, and R. verniciflua, which extracts were named the K-1, P-1 and R-1 in this order and the extract (KPR-1) was also prepared from the combined plant materials with each same weight of the three drugs.

This study was carried out to evaluate the effects of various kinds of salt on the quality and storage characteristics of tteokgalbi. The tteokgalbi was prepared using four types of salt: 1.5% purified salt (control, C), 1.5% five-year-old solar salt (FS), 1.5% Topan solar salt (TS), and 1.5% French Gu$\acute{e}$rande solar salt (GS). The moisture, crude lipid, crude ash, crude protein and calorie contents, water holding capacity, and cooking loss were not significantly different between control and all other treatments. As for the textural characteristics, the use of GS increased the hardness of the tteokgalbi. According to the sensory evaluation, the use of TS had the best score in springiness. Tteokgalbi made with TS and GS had the two highest scores in flavor and total acceptability. During 15 d of storage, the contents of 2-thiobarbituric acid (TBA) value, volatile basic nitrogen (VBN) and the total microbial counts increased, while the pH decreased. The TBA values of the tteokgalbi containing TS and GS were lower than that of C. Lightness (L) and yellowness (b) values decreased during storage, but redness (a) displayed no significant difference during storage. Overall, the best results, in terms of TBA value and sensory attributes, were obtained for the tteokgalbi containing TS and GS.

A feeding experiment was conducted to determine the use of distillers dried grain (DDG) as a partial replacement for fish meal in the diet for juvenile rockfish, Sebastes schlegeli. Four iso-nitrogenous (50% crude protein) and iso-caloric (4.3 kcal/g) diets (designated as DDG0, DDG7, DDG14, and DDG21) were formulated to contain 0, 7, 14, and 21% DDG. Triplicate groups of juvenile rockfish (initial body weight, $10.2{\pm}0.2g$) were fed one of the experimental diets to visual satiety twice a day (09:00 and 17:00) for 8 weeks. At the end of the feeding trial, survival of rockfish was above 97% and not affected by dietary DDG levels (P>0.05). Weight gain, feed efficiency and daily feed intake of juvenile rockfish were significantly decreased with increase of dietary DDG levels (P<0.05). Condition factor, hepatosomatic index and visceralsomatic index of juvenile rockfish were not significantly affected by dietary DDG levels (P>0.05). No significant differences were observed in the contents of moisture, crude protein, crude lipid and ash of the whole body and dorsal muscle in juvenile rockfish fed the experimental diets (P>0.05). Therefore dietary inclusion of DDG as a replacement for fish meal could depress the growth of juvenile rockfish.
