Abstract

A nano-class hard hollow capsule is prepared from refined starch and active protein through mixing them with modifier, thermodecomposing reaction, washing, drying, superfine treating (including thermomodifying), regulating pH value, adding cross-linking agent, preparing sol, adding coagulant and coagulating aid, stirring, dipping resin by template, baking, pulling shell, cutting and finishing.

Description

technical field [0001] The present invention relates to a kind of nano-biological technology extracting active ingredients, separating harmful substances, and ultramicro-resulting capsule compound---nano-scale hollow capsule. Used in medicine, food, cosmetics or other film-like products. In particular, it relates to a hollow nano capsule, and also relates to a method for preparing the hollow capsule. The hard hollow capsule obtained by the invention is similar to the traditional gelatin hard hollow capsule, and its performance is better than that of the gelatin hollow capsule. Background technique [0002] At present, gelatin is the most preferred raw material for hard hollow capsules, because it has properties such as gelling, film-forming and surface activity. Gelatin hard hollow capsules have certain temperature and humidity requirements for capsule production, transportation and storage. Under the stress of unfavorable environmental factors, the capsule changes greatl...
