摘  要：
采用国标方法对浙江地区的河蚬、环棱螺和圆田螺的营养成分进行分析并进行评价,以期为贝类的营养研究、饲料生产和开发利用提供理论依据。结果表明,环棱螺和圆田螺的水分、灰分、粗蛋白和粗脂肪的含量较为接近,而糖类的含量有较大差异;河蚬与环棱螺和圆田螺在主要营养成分组成方面差异较大。氨基酸分析结果表明,3种淡水经济贝类均含有18种氨基酸,其中包括人体必需的8种氨基酸,第一、二限制性氨基酸分别为缬氨酸和异亮氨酸。此外,谷氨酸含量远高于其他氨基酸,环棱螺中高达115.88mg/g,圆田螺中也高达98.68mg/g,2种螺肉的呈味氨基酸接近,含量均达40%以上。环棱螺和圆田螺的总氨基酸含量分别为653.28mg/g和561.67mg/g,必需氨基酸占总氨基酸的比例均在35%左右,与WHO/FAO模式推荐的模式(35.38%)接近。因此,3种淡水经济贝类软体部分的营养组成丰富,氨基酸种类齐全、比例均衡,具有较好的开发和利用价值。

摘  要：
The national standard methods was used to analyze and evaluate the nutrition components in the muscles of Corbicula fluminea,Bellamya aeruginosa,Cipangopaludina cathayensis in Zhejiang Province,which in order to supply theoretic basis for the nutrient research of mussels,production of feed and development of novel food.The results showed that water content,ash,crude protein,crude fat and in Bellamya aeruginosai and Cipangopaludina cathayensis were similar,but the content of carbohydrates were different.However,significant differences in ash,crude fat and carbohydrates between Corbicula fluminea and Bellamya aeruginosa,Cipangopaludina cathayensis were observed.There were 18 common amino acids in 3 freshwater mussels,of which 8 were essential amino acids,and the first limiting amino acid was Val and the second limiting amino acid was Ile.Moreover,the content of Glu was the highest among 18 amino acids in 3 freshwater mussels.The content of flavor amino acids was very close in Bellamya aeruginosa and Cipangopaludina cathayensis,which was up to 40%.The ratio of essential amino acids to total amino acids was approximately 35% and closed to the value recommended by WHO/FAO(35.38%).There were wealth of crude protein,crude fat and the kind and content of amino acids in the soft part of three freshwater mussels,which had a great prospect of the industrial process.
