ABSTRACT The proximate and amino acid compositions of the visceral mass and pedal mass of wild and farmed land snail Cornu aspersum were compared. The lipid in all body parts of farmed snail was significantly higher than all body parts of wild snail. The ash content of wild snail pedal mass was higher than all body parts of farmed snails. The dominant amino acid was glutamic acid (Glu), while the highest values of essential amino acids were leucine (Leu) and arginine (Arg) in all body parts of all snails. Sulfur amino acid was the lowest value in C. aspersum, which indicated that methionine (Met) and cysteine (Cys) could have been the first limiting amino acids. The study results showed that the protein efficiency rate (PER) of C. aspersum is close to PER of egg, which indicates a high protein quality and high biological value of land snails. The study also demonstrated that the experimental diet had good acceptability and well-balanced essential amino acid content, meaning that the farmed snails could have almost the same protein characterization as wild snails. Thus, all body parts of both wild and farmed C. aspersum have high protein quality.

养殖和野生陆地蜗牛的近似氨基酸和氨基酸组成的比较（Cornu aspersum Müller，1774）

摘要 比较了野生和养殖的陆生蜗牛 Cornu aspersum 内脏块和足块的近端和氨基酸组成。养殖蜗牛身体各部位的脂质含量明显高于野生蜗牛身体各部位。野生蜗牛足部的灰分含量高于养殖蜗牛的所有身体部位。在所有蜗牛的所有身体部位，主要氨基酸是谷氨酸（Glu），而必需氨基酸的最高值是亮氨酸（Leu）和精氨酸（Arg）。C. aspersum中硫氨基酸值最低，说明甲硫氨酸(Met)和半胱氨酸(Cys)可能是第一限制性氨基酸。研究结果表明，C. aspersum 的蛋白质效率（PER）接近鸡蛋的 PER，表明陆螺具有较高的蛋白质质量和较高的生物学价值。该研究还表明，实验饮食具有良好的可接受性和均衡的必需氨基酸含量，这意味着养殖蜗牛可以具有与野生蜗牛几乎相同的蛋白质特征。因此，野生和养殖的 C. aspersum 的所有身体部位都具有高蛋白质质量。
