Abstract

The invention discloses an edible packing material. The edible packing material is prepared from, by weight, 30 to 90 parts of hydroxypropyl methyl cellulose, 3 to 10 parts of soluble chitin, 0.5 to 5 parts of an adhesive, 1 to 10 parts of a plasticizer, and 0.1 to 2 parts of a food colouring. The formula of the edible packing material is reasonable; strength is high; the edible packing material is friendly to the environment, and is capable of reducing pressure on the environment; a preparation method is simple; raw materials are cheap; and the edible packing material is convenient for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to an edible packaging material. Background technique [0002] Edible packaging has important environmental protection and economic value. At present, there are two types of edible paper in foreign countries. One is to use vegetables as the main raw material, and the vegetables are beaten and then dried; the other is to gelatinize starch and sugar, add other food additives, and adopt a method similar to the papermaking process. forming. From the perspective of application and development prospects, green packaging materials with vegetables as raw materials have more development potential. Japan is the first country to research and develop vegetable paper. At present, Japanese vegetable paper has achieved large-scale production, and its processing technology and equipment have entered the fourth generation. The highest daily output can reach 30,000 sheets per production l...
