The purpose of this study was to evaluate the sensory characteristics and investigate the nutrients composition of sauce made with rock lobster shells or heads. Rock lobster head sauce(LHS) turned out to have better appearance, color, taste, flavor, texture and viscosity than rock lobster shell sauce(LSS). The crude protein content was 1.95% in LHS and 1.56% in LSS, and the crude lipid content was 1.60% in LHS and 2.27% in LSS. The major free amino acids of LHS were urea, a-aminoadipic acid, L-alanine, taurine, and those of LSS were urea, $\alpha$-aminoadipic acid, $nu$- and DL-$\beta$-aminobutyric acid. The major free fatty acids of both samples were palmitoleic acid and oleic acid, with a high quanitity of palmitoleic acid in LHS, and a significant amount of linoleic acid in LSS. The major minerals in rock lobster sauce were potassium and sodium.

This study was designed to compare content and composition of fatty acid in egg yolk oil among general eggs from chicken, quail, duck. We also compared those of general and functional chicken egg. Fatty acids were determined by GC method and the results were as follows: Palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and timnodonic acid were identified in egg of chicken, quail and duck. The major fatty acid was oleic acid and palmitic acid in three kinds of eggs. Arachidonic acid and docosahexaenoic acid (DHA) were analyzed in egg of quail , but no in chicken. Monounsaturaterd fatty acid (MUFA) was higher in egg yolk oil of chicken and quail. Polyunsaturated fatty acid (PUFA) was higher in duck egg. Ginseng egg had significantly higher palmitic acid and oleic acid lower than general chicken egg. Gamgoal egg had lower palmitic acid and oleic acid, and higher palmitoleic acid and stearic acid than general chiekcn egg. The content of oleic acid was lower in DHA egg than in general chiecken egg, but arachidonic acid was detected only in DHA egg. Ginseng egg had the highest content of saturated fatty acid among chicken eggs. The content of MUFA acid was the highest in gamgoal egg and general chicken egg. DHA egg had the most amount of PUFA among all chicken egg.

The fatty acid compositions of oocytes, follicular, oviductal and uterine fluids of pig and cow were analyzed using gas chromatography. Myristic (C 14: 0), palmitic (C 16: 0), palmitoleic (C 16: 1), stearic (C 18 : 0), oleic (C 18: 1), linoleic (C 18: 2), linolenic (C 18: 3) and arachidonic (C 20: 4) acids were identified as the common fatty acid constituents with little exception. Oleic acid composition was the highest (21.90 to 36.24%) in both pig and cow followed by palmitic (18.61 to 31.90%) and stearic (10.34 to 20.39%) acid. The three polyunsaturated fatty acids like linoleic, linolenic and arachidonic acids were detected in both pig and cow reproductive fluid samples. Myristic acid was not detected in pig oviductal fluid. Similarly, in cow oocytes myristic, palmitoleic and linolenic acids were not detected. Moreover, palmitic, stearic, oleic and linoleic acid comprised about 80% (73.74 to 88.00%) of the total fatty acids in the different samples analyzed in both animals.

The different developmental stage embryos and oviductal and uterine fluids of rabbit were analyzed by gas chromatography. Myristic (C 14:0), palmitic (C 16:0), palmitoleic (C 16:1), stearic (C 18:0), oleic (C 18:1), linoleic (C 18:2), linolenic (C 18:3), arachidic (C 20:0), arachidonic (C 20:4), docosahexaenoic (C 22:6) and lignoceric (C 24:0) acids were the common fatty acid constituents with little exception. In most of the samples palmitic, oleic, linoleic and arachidonic acids were observed in high concentration. Moreover, linoleic, linolenic and arachidonic acids were the three poly-unsaturated fatty acids in both type sample except day-1 oviductal fluids. Similarly, in both day-1 and day-2 oviductal and uterine fluids myristic, palmitoleic, stearic, linolenic, arachidic and docosahexaenoic acids were in less composition or undetected.
