Abstract

A water-type pseudo-emulsion of corn protein is proportionally prepared from corn protein, alcohol, plasticizer and distilled water through preparing the alcohol solution of corn protein and plasticizer, and mixing it with water. It can be used to prepare the high-toughness film used as the packing material of medicine, food, paper, etc.

Description

technical field [0001] The invention relates to a water system corn protein pseudo-emulsion and a preparation method thereof. Background technique [0002] Film coating is used on pharmaceutical solid preparations (such as granules, pills and tablets) to prevent moisture, mask bad odor and improve the appearance of the preparation. Film coating can also be used to control the release of drugs. [0003] Water-based coating has been widely used in pharmaceutical preparations. Compared with organic solvent coating, it is economical, pollution-free, and safe. When water alone is used as a solvent, it is limited to low-concentration polymer coating materials. As the concentration increases, the viscosity of the coating solution also increases, making coating difficult. Pseudo-emulsion coating is a kind of water-based coating. It has many advantages. The most important advantage is that the concentration and viscosity of pseudo-emulsion coating are not in a linear relationship. E...
