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.

酶法工藝生產(chǎn)的麥芽糊精與酸法工藝生產(chǎn)的麥芽糊精的區(qū)別在于不會(huì)析出長(zhǎng)鏈直鏈淀粉成分，故不會(huì)產(chǎn)生白色沉淀物，從而大大提高了麥芽糊精的商品價(jià)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.

酶法麥芽糊精放在水中，下沉很快，落在水底中，并能逐漸往上返，同時(shí)漸漸溶解，其溶解度略低于砂糖，但水化力較強(qiáng)。一旦吸收水分后，保持水分的能力較強(qiáng)。這是麥芽糊精的一個(gè)重要特性，在使用中常常會(huì)利用這一特性。

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，我國(guó)各地生產(chǎn)的麥芽糊精系列產(chǎn)品，均以玉米，大米等為直接原料，酶法工藝生產(chǎn)的。麥芽糊精廣泛應(yīng)用在糖果、麥乳精、果茶、奶粉、冰淇淋、飲料、罐頭及其他食品中，它是各類食品的填充料和增調(diào)劑。

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.
