鱼内脏油脂的脂肪酸组成分析研究及其利用价值的初探

Study on the Analysis of the Composition of Fatty Acid of Fat in the Guts of Fish and the Preliminary Study on Its Value of Utilization

前言近年来,水产加工业在开展鱼类保鲜的同时,大力推广“三去”(即,去头、去皮、去内脏)冷冻鱼的加工。由于集中加工,从而使鱼类加工的废弃物也能得以集中回收。这部分废弃物大约占原料鱼体重的1/5左右,若以加工1万吨“三去”鱼来计算,大约可得到2000吨的鳞、鳃和内脏等废弃物,而鱼内脏比例最大,其中含有丰富的粗蛋白约3～5吨,鱼油约100吨。为此,

Based on the analyses of the composition of fatty acid in intestinal fat of bighead,grass carp,filefish and Spanish mackerel,the writers considered that the composition of fatty acid in the intestinal fat bet-ween seawater and freshwater fishes was basically similar,and provided an evident for the future comprehensive utilization of the waste of fish.
