Snail eggs can be the raw material for the production of a caviar substitute. The substitute varies from the original in caloric value and nutrient content which determine the nutritional value of every foodstuff. The present study aimed to determine and compare the nutritional value and protein quality of eggs from two subspecies of edible snail.
The chemical composition of the snail eggs and was determined in accordance with international standards. In order to evaluate the protein quality of the eggs of the two studied snail subspecies, the chemical score (CS), and a reference protein were used.
Significant differences in the content of water, ash, and carbohydrates, but comparable protein and fat contents and caloric values were found.
The protein in the eggs of the snails was complete by the measure of the model adopted for this study, however, meeting the daily essential amino acid requirements of an adult would require an immense supply of both species' eggs. Snail eggs of the genus were characterised by much lower nutritional value in comparison with caviar and caviar substitutes.
蜗牛卵可作为生产鱼子酱替代品的原料。该替代品在热量值和营养成分上与原品不同,而热量值和营养成分决定了每种食品的营养价值。本研究旨在测定和比较两种可食用蜗牛亚种的卵的营养价值和蛋白质质量。
蜗牛卵的化学成分按照国际标准测定。为评估所研究的两种蜗牛亚种的卵的蛋白质质量,使用了化学评分(CS)和一种参考蛋白质。
发现水分、灰分和碳水化合物含量存在显著差异,但蛋白质、脂肪含量和热量值相当。
根据本研究所采用的模型衡量,蜗牛卵中的蛋白质是完整的,然而,要满足成年人每日必需氨基酸需求,需要大量这两个物种的卵。与鱼子酱和鱼子酱替代品相比,该属蜗牛卵的营养价值要低得多。
