半干盐渍仿刺参营养成分的分析及评价

Analysis and Evaluation of Nutrient Constituents of Semi-Dry Salted Apostichopus japonicus

为评价半干盐渍仿刺参营养价值,对其营养成分进行了全面测定与分析。结果表明,半干盐渍仿刺参中蛋白质、脂肪、总糖、灰分和水分的含量分别为11.8%、1.4%、0.3%、21.0%和64.5%;18种氨基酸的干重占比为38.8%,其中必需氨基酸占总氨基酸的26.2%,鲜味氨基酸、药效氨基酸分别占总氨基酸的55.8%和51.5%;常量元素中Na、Ca含量较高,分别为9.13×10~4 mg·kg^(-1)和2.22×10~3 mg·kg^(-1),微量元素中Fe、Zn含量较高,分别为106 mg·kg^(-1)和7.84 mg·kg^(-1);不饱和脂肪酸占脂肪酸总量的82.1%,其中EPA和DHA共占17.7%。半干盐渍仿刺参不仅利于存储运输,而且富含人体所需要的蛋白质、氨基酸等无机元素,具有很高的营养价值和经济利用前景。

In order to evaluate the nutritional value of semi-dry salinity Apostichopus japonicus,the nutritional composition was determined and analyzed comprehensively.The results show that the contents of protein,fat,total sugar,ash and water in semi-dry salted Apostichopus japonicus were 11.8%,1.4%,0.3%,21.0%and 64.5%,respectively;the dry weight ratio of the 18 amino acids was 38.8%,of essential amino acids represent 26.2%of the total amino acids,taste amino acids and medicinal amino acids accounted for 55.8%and 51.5%of the total amino 4-13 acids respectively;high content of Na and Ca in the constant elements,of 9.13×10 mg·kg and 2.22×10 mg·kg^(-1),-1 respectively,higher content of Fe and Zn in trace elements,106 mg·kg and 7.84 mg·kg^(-1),respectively;unsaturated fatty acids represent 82.1%of total fatty acids,both EPA and DHA altogether accounted for 17.7%.Semi-dry salted Apostichopus japonicus is not only conducive to storage and transportation,but also is rich in inorganic elements such as protein and amino acids needed by human body,and has high nutritional value and economic utilization prospects.
