Problems solved by technology

Ordinary microencapsulated starch can be divided into three types: lipophilic, hydrophilic and neutral. Lipophilic ordinary microencapsulated starch has a strong ability to embed substances with high fat content. Substances with high water content have strong embedding ability, while neutral ordinary microencapsulated starch can only embedding non-polar substances with low fat content and low water content, and its common defect is that it is not easy to dissolve in water, poor dispersion

Abstract

The invention relates to a starch deep processing technology, in particular to a production technology of microencapsulated starch. It is made by mixing ordinary microencapsulated starch with water, adding dodecenyl succinic anhydride with an amount of 3-8% of ordinary microencapsulated starch for cross-linking modification, and then adding ethanol to the obtained slurry to stir and mix well To obtain a precipitate, the precipitate is filtered and cleaned, dehydrated and dried, then pulverized and sieved to obtain a finished product. The microencapsulated starch has extremely strong lipophilicity and hydrophilicity, and can not only embed substances with high fat content, but also embed substances with high water content; the microencapsulated starch has excellent water solubility , easily soluble in water, even in cold water; the microencapsulated starch has strong resistance to mechanical damage, which makes the embedded object have good stability.

Description

technical field [0001] The invention relates to a starch deep processing technology, in particular to a production technology of microencapsulated starch. technical background [0002] At present, in the food, medicine, daily chemical, printing, pesticide and other industries, the modified starches used for the adsorption and embedding of target substances include cyclodextrin, lipidated starch, drug carrier microspheres and ordinary microencapsulated starch, among which cyclodextrin Dextrin, lipified starch, drug carrier microspheres and other modified starches have no holes in the starch granules, and the target object is embedded by wrapping the target object from the outer surface. The wrapping layer on the outer surface of the object is easy to break and fall off, so its anti-bounce performance is poor, so that the stability of the embedded object is not good, and it is not easy to dissolve in water. Ordinary microencapsulated starch has many tiny ho...
