Maltodextrin, also known as water-soluble dextrin or enzymatic dextrin. It is based on various types of starch as raw material, through enzymatic hydrolysis process control low level of conversion, purification, drying made. Its raw materials containing starch corn, rice and so on. May also be refined starches, such as corn starch, wheat starch, tapioca starch and the like. In 1970, Veberbacher of maltodextrin make the following definition: starch as raw material, by controlled hydrolysis of DE value of 20% or less of the product referred maltodextrin, in order to distinguish the starch pyrolyzed reaction product of dextrin. Main Characters and maltodextrin hydrolysis rate has a direct relationship, DE value represents not only the degree of hydrolysis, and is an important indicator of product characteristics to master. Understand the relationship between maltodextrin DE value products and properties between the right choice in favor of application of maltodextrin products.
Maltodextrin products are starch as raw material, through enzymatic hydrolysis process control turned into. Starch is a promise More glucose molecules polymerized carbohydrate; its molecular structure is mostly. α- (1,4) linkages, a small amount is α- (1,6) linkages. The use of high temperature α- amylase catalyzed hydrolysis of starch with a high degree of specificity, i.e., only a certain way in accordance with special properties and a certain portion of the hydrolysis of a certain kind glucoside linkages, only hydrolyzed starch, does not decompose protein, fiber, etc. . So maltodextrin is corn, rice and other raw materials, through enzymatic hydrolysis liquefaction control, bleaching, filtration, ion exchange, vacuum concentration and spray drying. Its apparent density 0.5g / CM3 less easily dispersed and dissolved water.
