主要质量问题:1.蛋白质、脂肪不达标。原因主要是原料乳中蛋白质、脂肪含量不足,或在原料中加入了非乳成分;另外,原料乳检测把关不严、生产工艺参数和配料计量控制不严、成品质量检验把关不够或缺少必要的检测手段等也有很大的关系。2.硝酸盐、亚硝酸盐超标。主要原因是生产用水中硝酸盐含量较高和原料乳检测把关不严,一些小型企业设备陈旧,管理混乱,环境卫生较差,导致产品微生物
The main quality issues: 1. Protein, fat does not meet the standard. The main reason is that the raw milk contains insufficient protein and fat, or non-milk ingredients are added to the raw material; in addition, the raw milk is not strictly monitored, the production process parameters and ingredient metering are not strictly controlled, and the finished product quality inspection is not enough or necessary. Testing methods, etc. also have a great relationship. 2. Nitrate, nitrite exceeded. The main reasons are the high nitrate content in production water and the lack of strict inspection of raw milk. Some small-sized enterprises are outdated in equipment, management is chaotic, and environmental sanitation is poor, resulting in product microbiology.
