Abstract

The invention relates to a preparation method of healthcare vegetable paper, which comprises the steps of: preparing vegetable pulp, preparing konjac glucomannan mixed forming agent, preparing mixed slurry, degassing, planking, drying and packaging. The preparation method provided by the invention uses the principles that the konjac glucomannan is a non-Newtonian fluid, the viscosity of denser konjac glucomannan solution is higher, and the performance of compounding with carboxymethyl cellulose sodium (CMC-Na) to form a film and the adhesiveness of the konjac glucomannan are good, fully combines the good healthcare function of the konjac glucomannan, improves the mechanical properties such as tensile strength, folding strength, the adhesiveness and the like and improves the nutritional value of the vegetable paper. The product forming effect is good, the color is bright and the vegetable paper is fragile but not smashing, is convenient to carry and is essential food for relaxation and travels.

Description

technical field [0001] The invention relates to a food and a preparation method thereof, in particular to a health-care vegetable paper and a preparation method thereof. Background technique [0002] Edible paper is one of the important development directions of healthy food packaging, with important environmental protection and economic value and great market potential. Edible paper mainly goes through two stages of development: (1) starch and sugar are refined, and then other food additives are added, and formed by a method similar to the papermaking process; (2) vegetables are used as the main raw material, and the vegetables are beaten and formed Then dry. The latter type of edible paper is rich in dietary fiber, vitamins and minerals because vegetables are rich in dietary fiber. Among them, dietary fiber is quite stable during processing and production, with little nutritional loss and low water content (about 10%), which is convenient for transportation and storage. ...
