Description
Technical field
A kind of crosslinked-enzymolysis or crosslinked-esterification-enzymolysis modified maltodextrin and preparation and application, belong to starch conversion deep process technology field.
Background technology
Because its unique physicochemical property of maltodextrin, purposes and cheap cost widely, abroad, the production of maltodextrin and use the history in existing more than 100 year; In China, since the eighties in 20th century, the maltodextrin project is competitively striven in various places, makes the production of this product that very big development arranged.For a long time, mainly concentrate on selection, production technique and equipment and the Application Areas of enzyme about the research of maltodextrin, and few to the expansion of product performance profound level, so the kind of product is comparatively single.With the increase of turnout, the defective effect of maltodextrin product the development of this industry, as, the easy moisture absorption of maltodextrin, to the conditional request height of storing; Product property is more single, emulsifying property, dispersed relatively poor etc.Present technique is exactly to develop a kind of agent of low hygroscopicity at the defective of maltodextrin, and the novel maltodextrin product of certain emulsifying property is arranged.
Summary of the invention
The object of the present invention is to provide a kind of crosslinked-enzymolysis or crosslinked-esterification-enzymolysis modified maltodextrin and preparation and application.By cross-linking of starch, or crosslinked-esterification makes cross-linking starch or crosslinked-esterification starch, and product makes crosslinked or crosslinked-esterification modification maltodextrin with the enzyme effect again, and this product water absorbability is low and have certain emulsifying effect.Utilize the production unit of existing maltodextrin, need not add too many production unit just can organically combine crosslinked, two kinds of method of modifying of esterification, produce modification maltodextrin product with new functionalized matter, product can be used as the functional factor and the sustained release dosage of food and medicine industry, has overcome the defective of easy moisture absorption of traditional maltodextrin and emulsifying property difference.
Technical scheme of the present invention: a kind of crosslinked-enzymolysis modified maltodextrin, used starch cross-linking modifiedly, the method for enzymolysis prepares crosslinked-enzymolysis modified maltodextrin again.A kind of crosslinked-esterification-enzymolysis modified maltodextrin, used, esterification modification crosslinked to starch, the method for enzymolysis prepares crosslinked-esterification-enzymolysis modified maltodextrin again.The maltodextrin of modification has agent of low hygroscopicity, low viscous characteristic, and has given parents function.
The preparation method of described modification maltodextrin, with starch or amyloid material is raw material, add water and be made into certain mass fractional starch suspension, add linking agent and carry out cross-linking modifiedly, or add linking agent and carry out cross-linking modified and drip esterifying agent carrying out esterification modification, after washing, be deployed into the certain mass fractional suspension of treated starch again, add amylase and carry out enzymolysis, the enzyme that goes out filters, spraying drying makes crosslinked-enzymolysis modified maltodextrin or crosslinked-esterification-enzymolysis modified maltodextrin.
Starch material can be W-Gum, wheat starch, potato starch or amyloid raw material, as broken long-grained nonglutinous rice powder etc.
