Pectinase refers to enzymes that decompose pectin, the main component of plants. Pectinase is widely distributed in higher plants and microorganisms. Pectinase is essentially polygalacturonic acid hydrolase. Pectinase hydrolyzes pectin mainly to produce -galacturonic acid. Sodium hypoiodate method can be used to quantify galacturonic acid to determine the activity of pectinase. Application: Food Industry (used in dairy foods, baked goods, various beverages, candies, condiments, etc.), Feed Industry (pet canned food, animal feed, aquatic feed, vitamin feed, etc.), Industrial Industry (petroleum industry, manufacturing, agriculture, ,Technology research and development, etc.), Daily Chemical Industry (facial cleanser, toner, shampoo, shower gel, toothpaste, etc.), other industries. Pectinase is the most important enzyme in fruit processing. Using pectinase to treat broken fruits can speed up the filtration of juice and promote clarification. Use other enzymes together with pectinase, the effect is more obvious.
