胶原蛋白肠衣的主要原料为动物活性胶原蛋白，增加蛋白质作为胶原蛋白肠衣的特征指 标。
The main material of collagen intestinal coat is animal active collagen. Increasing protein is the characteristic index of collagen intestinal coat.
胶原蛋白肠衣中的水分含量高低会影响肠衣的柔韧性和保存期限，水分过低会导致肠衣 干裂和易断，水分过高又会导致肠衣霉变影响保存期限，增加水分指标的目的是控制肠衣既 能保持合适的柔韧度又能防止肠衣霉变。
The water content in collagen sausage will affect the flexibility and shelf life of the sausage. Low water content will cause the sausage to crack and break. High water content will also cause the sausage to mildew and affect the shelf life. The purpose of increasing water index is to control the sausage not only to maintain the appropriate flexibility but also to prevent the sausage from mildewing.
蛋白质和水分这两项指标是参照美国、日本等国生 产的胶原蛋白肠衣产品的相关要求和本次采集的胶原蛋白肠衣样品的检测数据而定。
The two indicators of protein and water are based on the relevant requirements of collagen intestinal products produced in the United States, Japan and other countries, and the detection data of collagen intestinal samples collected in this study.
