摘  要：
为有效的开发和利用铜仁地区螺类资源,采用恒温干燥、凯氏定氮、甲醇-氯仿等方法对锦江河铜锈环棱螺(Bellamya aeruginosa)、梨形环棱螺(Bellamyapurificata)和三带田螺(Viviparus tricinctus)3种淡水螺的营养成分进行分析与评价。结果表明:3种淡水螺鲜样中的水分含量为74.10%~79.43%,粗蛋白为13.33%~14.64%,粗脂肪为0.58%~0.65%,灰分为3.07%~5.25%;铜锈环棱螺、梨形环棱螺和三带田螺干样中均含有16种氨基酸,包含人体必须氨基酸7种,必需氨基酸占总氨基酸的比例分别为37.04%、35.95%和35.60%,蛋氨酸和缬氨酸为第一和第二限制氨基酸。此外,3种螺肉中的鲜味氨基酸含量接近,均达39%以上。

摘  要：
Analysis and evaluation on nutritional composition of Bellamya aeruginosa,Bellamyapurificata and Viviparus tricinctus in Jinjiang River,were conducted to efficiently exploit and utilize snails resources.The results showed that the contents of moisture,crude protein,crude fat and ash of the three freshwater snails were 74.10%~79.43%,13.33%~14.64%,0.58%~0.65% and 3.07%~5.25%,respectively.There were 16 common amino acids in the three freshwater snails,of which seven were essential amino acids,and the first limiting amino acid was Met and the second was Val.The ratio of total essential amino acids to total amino acids(WEAA/WTAA)were 37.04%,35.95% and 35.60%,respectively.The content of flavor amino acids was very close in B.aeruginosa,B.purificataand V.tricinctus,which was up to 39%.
