  • This study was conducted to derive consumption of persimmon by the expansion of utilization of the persimmon flesh and peel. The valuable components were investigated in persimmon flesh and peel. Crude protein and fat contents in persimmon peel were higher than flesh but soluble sugar was more higher in flesh (with 71.3%) than peel (with 54.2%). Major free sugar in persimmon peel were glucose and fructose, the composition was similar to flesh. Major total amino acids in persimmon peel were glutamic acid, proline, methionine and aspartic acid. Proline, arginine, valine and alanine were relatively high in free amino acid. Oleic acid, linoleic acid and palmitic acid were the major fatty acid in persimmon peel, and the content of unsaturated fatty acid was more higher than flesh. Sugar cookies were processed using persimmon flesh and peel, when these powder were mixed with $5{\sim}10%$ to raw materials, the preference score was increased. Steamed rice cakes with persimmon were processed using persimmon flesh and peel, when sliced-dried persimmon was mixed to $10{\sim}20%$, the preference was increased, but persimmon peel was not. The quality of gruel which processed using persimmon flesh powder improved when mixed with flesh powder of 3%, rice powder, glutinous rice powder and skimmed milk, but persimmon peel was not suitable for gruel processing.

  • In order to increase the availability of filefish scrap, the ordinary and low salt sauce were prepared, and identified their taste compounds in their products. To process the filefish scrap sauce, chopped filefish scrap was mixed with koji, 25% brine, slat and glucose (25.0 : 65.0 : 12.5 : 7.0, w/w) and fermented at $25{\pm}4^{\circ}C$ for 120 days. The same process was also carried out to process the low salt sauce adding sorbitol, lactic acid and ethyl alcohol (7.0 : 0.7 : 9.0. w/w) instead of salt. While amino nitrogen and volatile basic nitrogen(VBN) of products were decreased, pH and reducing sugar were increased all alone the fermentation period. The major free amino acids of products at final stage of fermentation were glutamic acid, alanine, leucine, lysine and aspartic acid. And the contents of total amino acid in the ordinary and low salt sauce were 4126.6(mg/100m1 sauce), 4519.5(mg/100m1 sauce) after fermentation. Hypoxanthine was revealed as the major constituent among nucleotides and their related compounds through fermentation. Free amino acid-N in the filefish scrap sauces were from 56.3%(ordinary) to 60.7%(low salted) of extractive nitrogen. From the sensory evaluation, the quality of products from filefish scrap sauce were almost equal to sold soy sauce on the market.

  • The objective of this study was to analyze fatty acid composition in lipids extracted from bullfrogs (Rana catesbeiana Shaw) inhabiting in Korea. Lipid contents in bullfrog legs and bodies were less than 1% (w/w, wet basis) and seasonal variation of the lipid contents was not observed. Lipids in bullfrog legs consisted of 26~31% (w/w) saturated fatty acids, 16~24% monounsaturated fatty acids, and 30~40% polyunsaturated fatty acids. Lipids in bullfrog bodies consisted of 23~28% saturated fatty acids, 29~44% monounsaturated fatty acids, and 16~30% polyunsaturated fatty acids. The major fatty acids in lipids extracted from bullfrogs were palmitic acid, oleic acid, and linoleic acid. Lipids in leg muscles contained 3~8% eicosapentaenoic acid (EPA) and 6~10% docosahexaenoic acid (DHA). Lipids in bodies had 1~3% EPA and 1~3% DHA.

  • The purposes of this research were to assess dietary fatty acid patterns and to elucidate the relationship between the serum cholesterol levels and dietary fatty acid patterns, plasma fatty acid compositions, BMI (body mass index), and other lipid profile. The subjects were 151 adults aged 23 to 80 years, selected from the Outpatient Clinic and Cardiova-scular Department of the Seoul Municipal Hospital. Dietary data were obtained using three day food records. Sixteen dietary fatty acids were analyzed using Korean and US nutrient databases. The subjects were divided into three serum cholesterol levels: desirable (< 200 mg/dl, N = 44), borderline-risk ($\geq$ 200 - < 240 mg/dl, N = 35), and high-risk ($\geq$ 240 mg/dl, N = 72) groups. The high-risk group had higher BMI, waist, and waist to hip ratio (WHR) than the desirable and borderline-risk groups. Serum concentrations of triglyceride, LDL cholesterol and LDL/HDL cholesterol ratio were significantly higher in the high-risk group as compared to those in the other two groups. The serum cholesterol levels were highly correlated with BMI (r = 0.435), triglyceride (r = 0.425) and LDL/HDL cholesterol (r = 0.870) ratio. The highest fatty acid intake was from oleic acid (33 - 34% of total fatty acid intakes), which was followed by linoleic acid (27%), palmitic acid (19%), and stearic acid (7%). There was no correlation between the serum cholesterol levels and the dietary fatty acid intakes, polyunsaturateumonounsaturateusaturated fatty acids (P/M/S) and $\omega$6/$\omega$3 ratios. The correlation between plasma fatty acids such as myristic acid, oleic acid, linoleic acid, and docosahexaenoic acid and serum cholesterol levels was also weak.

  • Infant formula is one of the main nutritional sources for infants. In this study, the fatty acid compositions of Korean (domestic, n=8) and foreign infant formulas (n=3) were analyzed. Crude fats were extracted using the Folch method, and fatty acid compositions (total and positional) were analyzed by gas chromatography. In the fatty acid compositions of infant formulas, oleic (19.88~44.64%), palmitic (7.59~21.65%) and linoleic acids (16.72~25.87%) were the major fatty acids. Domestic infant formula products contained 35.94~56.55% total saturated fatty acid content, whereas that of foreign infant formula ranged from 34.40~42.88%. The content of monounsaturated fatty acids ranged from 20.23~44.99% in domestic products and 34.11~45.07% in foreign products. In addition, 0.17~2.57% arachidonic acid/docosahexaenoic acid and 10~13% linoleic acid/linolenic acid were detected in the analyzed products (domestic and foreign products). A small amount of trans fatty acids (0.25~1.69%) were found. In sn-2 position analysis, palmitic acids (1.84~38.74%) were detected in the analyzed formulas. Further, typical triacylglycerols in human milk, including 1,3-di-monounsaturated-2-saturated triacylglycerol, were not detected in the analyzed formulas.

  • This experiment was conducted to compare the influences of dietary dried persimmon by-product(DPB) on performance, blood cholesterol and fatty acid composition in broiler chicks. Diets contained 21.5 and $19\%$ CP for the starting and finishing period, respectively. The ME was 3,100kcal/kg in diets for both starter and finisher diets. One hundred sixty chicks were assigned to 4 treatments with 4 replicates at different levels of dried persimmon by-product. Treatments were consisted of 0(control), 1(T1), 3(T2) and $5\%$ (T3) DPB. Body weight gain was higher in treatment groups fed the starter diet but was the lowest in T3 for finishing period. Feed efficiency was not significantly different. In proximate composition, crude fat of chicken meat were increased in diets by addition of DPB than control, but moisture and crude ash was no significantly different. The total cholesterol, HDL, and triglyceride of treatment groups was higher than control. The LDL of control was higher than treatment groups. In fatty acid composition, oleic acid contents of treatment groups were higher than control, whereas stearic, linoleic acid contents lower in meat composition than control. In conclusion, dietary supplementation of DPB at $3\%$ level tended to improve growth performance of broiler chicks.
