一种耐高温可食蛋白肠衣的制作方法，其特征在于包括如下工艺步骤，（１）将动物内层皮，用水浸，然后用枯草杆菌碱性蛋白酶液经１０－－４０天浸泡处理，按皮重加０．０３－－０．５％枯草杆菌碱性蛋白酶，按皮重量的１－２倍加水形成枯草杆菌碱性蛋白酶液；（２）水洗、分割后皮料用ｐＨ值为２－２．５的盐酸液洗，再用ｐＨ值０．５－１的盐酸液浸泡成半透明膨胀状；（３）调整控制物料ｐＨ值在２．５－３．５进行切碎，压片，压片料加食用油剂、可溶纤维素、水和盐酸液调整物料ｐＨ值为２．５－３．２之间，含水质量８９％－９１％进行搅拌均匀成胶原团，（４）胶原团经过滤后挤压成型，成中空管状物；（５）管状物干燥，并淋上醛液固化剂和甘油塑化剂处理；（６）在８５－９５度温度及高湿度下熟化；（７）折叠卷绕或套缩后包装得到成品。

Manufacturing method of a high temperature resistant edible protein casing, characterized in that it comprises the following process steps, (1) the animal skin, water immersion, with Bacillus subtilis alkaline protease solution and then after 10 - 40 days for treatment, according to the 0.03 - plus tare 0.5% Bacillus subtilis alkaline protease, by 1 - 2 double skin weight water form Bacillus subtilis alkaline protease solution; (2) after washing, split leather with pH value of 2 - 2.5 hydrochloric acid washing, then the value of pH hydrochloric acid solution for 0.5 - 1 of the expansion into a translucent shape; (3) adjusting control material pH value in the 2.5 - 3.5 tablet to chop. Tablet, feeding agent, edible oil soluble cellulose, water and hydrochloric acid to adjust material pH value of 2.5 - 3.2, 89% - 91% of water quality Stir into collagen, collagen (4) group after filtration extrusion molding, a hollow tubular material; (5) drying tube, and pour the liquid aldehyde curing agent and plasticizer glycerin treatment; (6) in the 85 95 temperature and high humidity aging; (7) winding or folding set after shrinking packaging to obtain the finished product.
