Embodiment 1

[0018] The edible film material is prepared from bran, which is made from the following raw materials in mass proportion:

[0019] Bran 80, gelatin 15, nano silicon dioxide 3 parts, lecithin 1.2, saponin 0.8, protease 1.5, glucoamylase 2;

[0020] Preparation:

[0021] (1) The bran is finely ground and sieved, and the particle size is 120 mesh;

[0022] (2) The mass ratio of bran and water is 1:5, put into the reaction kettle and heat up to 65°C, add protease and glucoamylase, and enzymatically hydrolyze for 6 hours to obtain an enzymatically hydrolyzed bran solution;

[0023] (3) The temperature of the enzymatically hydrolyzed bran solution is lowered to 12°C, poured into a centrifuge for separation at 2500r / min, and the bran and other large particle residues are removed to obtain a centrifuge;

[0024] (4) Add gelatin, nano silicon dioxide, lecithin and saponin to the centrifuge liquid, raise the temperature to 90° C., stir for 30 min, and adjust the pH value to 7.5 to obt...

Abstract

The invention discloses a method for preparing an edible film material through bran, and relates to the technical field of novel film material production. The method comprises the steps that the bran is subject to fine grinding and screening, and the fineness of particles is 120 meshes; the mass proportion of the bran to water is 1:5, the bran is put into a reaction kettle to be heated to 65 DEG C, protease and saccharifying enzyme are added, and enzymolysis is carried out for 6 hours; the temperature is reduced to 12 DEG C, the bran is poured into a centrifugal machine to be separated, and the bran and other large particle slag are removed; gelatin, nanosilicon dioxide, lecithin and saponin are added, the temperature rises to 90 DEG C, stirring is carried out for 30 min, and the pH value is adjusted to 7.5; spray drying is carried out, and the edible film material is obtained. The new way for utilizing the bran is provided, the bran can be subject to deep machining, the added value of products is high, the production technology is suitable for batched production of an enterprise, the investment is small, the product quality is high, the produced edible film material can be used for producing edible thin films, a new material is provided for the food and the food packaging field, moisture can be isolated, food can be prevented from absorbing moisture, infectious microbe breeding is avoided, and the food can be well protected.

Description

technical field [0001] The invention relates to the technical field of production of novel film materials, in particular to a method for preparing edible film materials from bran. Background technique [0002] Bran is the outermost skin of wheat. After the wheat is processed by a flour mill, it becomes flour and bran. Bran is the outer skin of wheat. Most of them are used as feed, such as feeding pigs. However, when bran is used as feed, its application value is low, and developing new application fields is an important way to improve the application value of bran. Contents of the invention [0003] The purpose of this invention is to provide a kind of method that uses bran to prepare edible film material, to solve above-mentioned technical problem. [0004] The technical problem to be solved by the present invention is realized by the following technical solutions. [0005] A method for preparing edible film material with bran, characterized in that the steps are: [0...
