用凝固卵蛋白测定胃酶消化力的现行方法基本上适应了胃蛋白酶生产和质检的需要,但实践证明这一方法还存在着测定结果重现性差,操作人员需要重复测定的缺陷。即便是有经验能熟练操作的人员用同群同一饲养条件的莱克亨鸡所产的蛋、筛选出不适于用来测定的感官认为较稀软和较硬实的凝固卵蛋白,测得结果仍然是误差较大。近年来我厂在不同的季节将按照测定法制作的凝固卵蛋白进行干物质(105℃不挥发物)的定量测定,证实测定用凝固卵蛋白即使来自
The current method of measuring peptic digestion with coagulated egg protein basically meets the needs of pepsin production and quality control. However, this method has proved to be disadvantageous in that reproducibility of measurement results is poor and operators need to repeat the determination. Even those skilled in the art who used eggs from Lake Genghis of the same breeding conditions to screen out coagulant ovalbumin, which the sensory organs which are not suitable for the measurement, are considered to be softer and harder, the result is still The error is larger. In recent years, our factory will be in different seasons according to the determination of the production of solidified egg protein for quantitative determination of dry matter (non-volatile matter 105 ℃), confirmed the determination with the solidified egg protein from
