Maltodextrin series products are made from starch by enzymatic hydrolysis. Starch is a carbohydrate polymerized from many glucose molecules; Most of its molecular structure is based on. α— (1, 4) key connection, with a small amount of α— (1, 6) key connection. Utilize high temperature resistance α— The catalytic hydrolysis of starch by amylase is highly specific, that is, it can only hydrolyze certain types and parts of glucoside bonds in a certain way, only hydrolyze starch, and does not decompose protein, cellulose, etc. Therefore, maltodextrin is made from corn, rice and other raw materials through enzymatic control of hydrolysis, liquefaction, decolorization, filtration, ion exchange, vacuum concentration and spray drying. Its apparent density is below 0.5g/CM3, which is easily dispersed and dissolved in water.

酶法工艺生产的麦芽糊精与酸法工艺生产的麦芽糊精的区别在于不会析出长链直链淀粉成分，故不会产生白色沉淀物，从而大大提高了麦芽糊精的商品价值。

The difference between the maltodextrin produced by the enzymatic process and the maltodextrin produced by the acid process is that it will not separate the long chain amylose component, so it will not produce white sediment, thus greatly improving the commercial value of the maltodextrin.

酶法麦芽糊精放在水中，下沉很快，落在水底中，并能逐渐往上返，同时渐渐溶解，其溶解度略低于砂糖，但水化力较强。一旦吸收水分后，保持水分的能力较强。这是麦芽糊精的一个重要特性，在使用中常常会利用这一特性。

Enzymatic maltodextrin, when placed in water, sinks quickly, falls on the bottom, and gradually returns to the top, while gradually dissolves. Its solubility is slightly lower than that of granulated sugar, but its hydration force is strong. Once the water is absorbed, the ability to maintain water is strong. This is an important characteristic of maltodextrin, which is often used.

目前，我国各地生产的麦芽糊精系列产品，均以玉米，大米等为直接原料，酶法工艺生产的。麦芽糊精广泛应用在糖果、麦乳精、果茶、奶粉、冰淇淋、饮料、罐头及其他食品中，它是各类食品的填充料和增调剂。

At present, the series of maltodextrin products produced in various parts of China are all made of corn, rice, etc. as direct raw materials by enzymatic process. Maltodextrin is widely used in candy, malt, fruit tea, milk powder, ice cream, beverages, cans and other foods. It is the filler and conditioner of various foods.
