摘要:

测定和分析杉虎斑的营养成分,并对其营养价值进行综合评析,旨在为该鱼营养学研究及其配合饲料的研发提供基础资料和理论依据。结果表明:杉虎斑含肉率为74.31%;全鱼水分、粗蛋白、粗脂肪、粗灰分、钙和磷的含量分别为71.50%、20.45%、2.45%、2.88%、1.68%和0.92%。杉虎斑肌肉中水分、粗蛋白、粗脂肪和粗灰分含量分别为74.60%、20.52%、2.48%和1.23%。杉虎斑肌肉中含18种氨基酸,其中人体必需的8种氨基酸含量总和为6.89%,占氨基酸总量的41.67%;4种鲜味氨基酸含量总和为6.31%,占氨基酸总量的38.60%;必需氨基酸指数为78.21,必需氨基酸组成符合FAO/WHO标准;饱和脂肪酸占脂肪酸总量的35.56%,多不饱和脂肪酸占36.46%,其中EPA和DHA的含量分别为6.55%和12.35%。杉虎斑肌肉中矿物质含量丰富。综上所述,杉虎斑是一种营养价值较高的经济海水鱼类。

Abstract:

In this study,nutritional components in the body and muscle of a new hybrid grouper(E.fuscoguttatus ♀×E.polyphekadion ♂)were tested and analyzed with routine methods,in order to evaluate its nutritive value and offer basic date and theoretical basis for the research of its nutrition and the development of formula feed.The results showed that the ratio of flesh content was 74.31%,the contents of moisture,crude protein,crude fat,crude ash,Ca,and P of fresh body were 71.50%,20.45%,2.45%,2.88%,1.68% and 0.92%,respectively.The contents of moisture,crude protein,crude fat and crude ash of the hybrids’ fresh muscles were 74.60%,20.52%,2.48%and 1.23%,respectively.There were 18 kinds of amino acids in the muscle,including 8 essential amino acids (EAA) for human body and 4 delicious amino acids.The content of EAA was 6.89%,which accounted for 41.67% of the total amino acids.The content of tasty amino acids was 6.31%,which accounted for 38.60% of the total amino acids.The essential amino acid index (EAAI) was 78.21.The composition of EAA conforms to FAO/WHO standards.The proportion of saturated fatty acids (SFA) was 35.56%,and the proportion of polyunsaturated fatty acids (PUFA) was 36.46%.EPA and DHA accounted for 6.55% and 12.53% of the total fatty acids,respectively.10 kinds of mineral elements were detected in the muscle.The content of macro elements in muscle from high to low was K>P>Mg>Na>Ca.Among the trace elements,the content of Fe was the highest and the content of Se was the lowest.To sum up,the hybrid grouper(E.fuscoguttatus ♀×E.polyphekadion ♂)was a kind of high quality economic marine fish with good edible value and nutritive value,worthy of exploitation and utilization.

Key words: Epinephelus fuscoguttatus ♀×E.polyphekadion ♂, nutritional composition, muscle, amino acids, fatty acids, mineral elements
