保存条件 1. 蛋白肠衣保存在厂家的包装里，库房应该是避光、干燥，室温控制在15—25℃之间，空气相对湿度为65-75％，冬季保存时离暖气设备不少于1米。 2.蛋白肠衣保存期为12个月。 3. 建议包装在使用前打开。 如果肠衣在低温下运输﹝如冬季﹞，需要2天内不打开肠衣包装，保持在 15—25℃之间回温后再使用。 二.使用前条件的准备 套缩肠衣使用前不需要溶液浸泡。 新鲜的胶原蛋白肠衣在使用过程中,不需要使用任何的油及其它的液体。因为热处理以后香肠需要用凉水 ,喷在肠衣上,使肠衣没有发粘现象。如果肠衣在库房存留半年以上还需要继续使用而且肠衣发干的特殊情况下，为增加软性或者润滑性可用食用油来改善，但是只能把油刷在肠衣的表面上，不能把肠衣放在油里浸泡。 Preservation conditions 1. Preserving protein casing in manufacturer's packaging, should be avoid light, dry warehouse, room temperature control between 15 to 25 ℃, relative air humidity is 65-75%, winter kept away from the central heating is not less than 1 m. The retention period for protein is 12 months. It is recommended that the packaging be opened before use. If casing transport (like winter) under low temperature, need 2 days do not open the casing packaging, keep back between 15 to 25 ℃ temperature before using. No solution is needed before using the precondition for the preparation of the casing. Fresh collagen casing doesn't require any oil or other fluids during use. Because of heat treatment the sausage needs to use cold water, spray on the casing, make the casing is not sticky. If casing kept in warehouse for more than six months still need to continue to use and casing dry under special circumstances, to increase soft or lubrication oils available to improve, but can only put the painting on the surface of the casing, can't put the casing in oil soak.
