山梨酸

山梨酸是国际粮农组织和卫生组织推荐的高效安全的防腐保鲜剂，对酵母、霉菌和许多真菌都具有抑制作用，是高效无毒防腐防霉剂，广泛应用于食品、饮料、烟草、农药、化妆品等行业，作为不饱和酸，也可用于树脂、香料和橡胶工业；山梨酸在食品工业中作为食品添加剂，为保障其安全，对其有害物质进行监控，本实验室可作山梨酸外观以及褪色和最大吸收峰的鉴别实验，用滴定法测定山梨酸的含量，用干燥法测定灼烧残渣的含量，重金属(以铅计）的含量，用砷斑法测定砷的含量，用电量法测定水分的含量。Sorbic acid is a highly efficient and safe antiseptic and preservative recommended by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). It exerts inhibitory effects against yeast, molds and various fungi, and is recognized as a high-efficiency, non-toxic antiseptic and antifungal agent. It is widely applied in industries including food, beverages, tobacco, pesticides, cosmetics and others. As an unsaturated carboxylic acid, it can also be used in the resin, fragrance and rubber manufacturing industries. As a food additive in the food industry, sorbic acid requires monitoring of its harmful substances to ensure food safety. This laboratory is capable of conducting identification tests for sorbic acid, including its appearance, discoloration and maximum absorption peak. The content of sorbic acid can be determined via titration, the content of ignition residue via the drying method, the content of heavy metals (calculated as lead), the arsenic content via the arsenic spot test method, and the moisture content via the electrolytic method.
