Edible mix film and production process mainly with casting technique thereof

Abstract

The invention discloses an edible mixed film and method for preparation, which is subject to tape casting process, and aims to provide the edible mixed film and method for preparation, which is made by edible plants and vegetable protein or / and starch and has various nutrition. According to weight percentage, the mixed film of the invention comprises 10-35 percent of edible plants, 80-50 percent of vegetable protein or / and vegetable starch, and 5-25 percent of auxiliary materials. The invention further provides a method for preparing mixed film using tape casting. Paper film of the invention is neither simple vegetable paper nor a simple protein film or a starch film, the nutrition is rich, and the invention integrates the advantages of physical and chemical properties of the vegetable paper and the protein film or the starch film. Further, the invention provides the method for preparation which is subject to the tape casting process and related technology, thereby overcoming the difficulties in the production process and technology. The mixed films are capable of being used as edible packaging of food, and also are capable of being used as food to eat directly.

Description

An edible mixed film and its production method based on casting technology technical field The present invention relates to an edible packaging material, more specifically, relates to an edible mixed film made of edible plants and vegetable protein or / and vegetable starch and its production method mainly based on casting technology. Background technique At present, the environmental pollution caused by plastic-based packaging and waste of daily necessities has attracted the attention of the world. People are committed to finding new degradable materials, and even preparing edible packaging materials, such as vegetable paper, protein film, etc. . Vegetable paper originated in Japan, and some domestic scholars are also committed to improving research in this area. Protein film and starch film are also the focus of many scholars and some scholars' research hotspots. Protein films include animal protein films and plant protein films. Whether it is vegetable paper, protein ...

AI Technical Summary

Problems solved by technology

Whether it is vegetable paper, protein film or starch film, they are all made of a single substance, which has a single nutritional component and has its own shortcomings in physical and chemical properties.

Animal protein edible film has a certain degree of flexibility, but it will change color after a long time of storage and the smell and taste are poor; simple vegetable protein film has the disadvantages of high brittleness and low strength, which need to be solved by adding auxiliary materials; vegetable paper has the physical properties of paper and contains vegetable Similar Nutrients

Moreover, when the cast method is used for production, due to the difficulty of removing the film, the method of adding additives is often used to solve the problem of difficult removal of the film, and the preparation process is complicated.
