Abstract

The invention discloses a method for preparing low-density maltodextrin, which comprises the step of taking corn or rice or tubers as a raw material, and steps of size mixing, spraying and liquefying, micropore refining and spray drying to obtain the product. The method improves and optimizes the prior producing technology of the maltodextrin, namely preparing starch to have low density suitable for liquefying enzyme and have a pH value of between 3 and 5, spraying and liquefying the starch twice by high temperature, and refining the starch by a micropore. The density of the product prepared by the spray drying reaches less than 0.10 g / cm<3>; and the product is in shape of hollow ball, and has the advantages of large apparent solubility, low sweetness, low hydroscopic property, no easy caking, and the like.

Description

technical field

[0001] The invention relates to a preparation method of maltodextrin. Background technique

[0002] The known maltodextrin is a starch hydrolyzate produced by hydrolysis of starch as raw material after liquefaction with enzyme or acid. Maltodextrin is a kind of nutritional polysaccharide without any taste. It is widely used in various food ingredients due to its mild taste, low sweetness, weak hygroscopicity and good solubility. For example, maltodextrin can be used as filler, humectant, dispersant, film former, etc.

[0003] At present, the research on the production method of maltodextrin has been relatively in-depth, and the research hotspots mainly focus on the production of low DE value maltodextrin. For example, patent CN1528910 discloses a jet liquefaction enzyme method to prepare low DE value maltodextrin. Starch or indica rice flour is used as raw material, and products with a DE value of 2 to 6 are produced through processes such as spraying, heat...
