Analysis of Fatty Acids Composition of Longdong Black Goat Muscle Tissue by Gas Chromatography-Mass Spectrometer

Abdalhaleem Jabir Babour, Jin Mei Wei and Yuzhu Luo

The current study determines the composition of Fatty Acid (FA) of Longdong black goat muscle tissues (Chinese breed) with analysis in sex of representative, Longdong black goat muscle tissues (30 from females and 30 from males) were determined using Mass spectrometer. The results approved that female’s goats muscle tissues had a lower amount of Saturated Fatty Acid (SFA) with 27.87%, than males with 28.06%. Oleic acid C18:1 is 18.15% in females to 27.15% in males. Higher proportion of Poly Unsaturated Fatty Acids (PUFA) Linoleic acid (C18:2), arachidonic acid (C20:4n3c) with 15.45%, 11.14% respectively in cut male’s muscle tissue. Eicosatetraenic acid (C20:5n3c) was found 17.76% in female’s muscle. Omega-3 Polyunsaturated Fatty Acids (PUFA) Linolenic acid (C18:3n3) and docosahexaenoic (C22:6n3) with 2.4% and 2.58% were observed in both sex goat muscles tissue. SFA were found in low values between 12% to 1.08% in both sex muscle tissues. PUFA ratio was higher than SFA ratio in males with 31.90% and in females 27.87%. Monounsaturated fatty acid (MUFA) levels also were observed higher with about 29.21% than the values of saturated fatty acids (SFA) values 27.87% in females. All muscle tissues in both females and males have the same type of fatty acid composition with different in proportions, there is a little effect in sex proportions.
