Prospect of glutinous rice paper

Packaging food with sticky rice paper, especially the inner packaging of food, is the most hygienic requirement. However, the strength of glutinous rice paper is very limited, and it is not resistant to damp and heat, so it can not be widely used to package various foods.

If soybean protein and edible cellulose are used to improve the physical and chemical properties of glutinous rice paper, enhance its strength, moisture resistance and heat resistance, and make it quite elastic, flexible and foldable, it will form a new type of environmentally friendly edible packaging paper with wide applications, cleanliness and hygiene.

Some people spin soybean protein into cloth, and it is not a problem to use it as edible wrapping paper. Facing the present and future market, soybean glutinous rice paper has a good development prospect.
