Embodiment 1

[0014] Example 1: The wheat bran dietary fiber is pulverized and the particle size range is 200 meshes, and it is mixed with water to make the concentration of the material liquid reach 10% (w / v), the temperature is 50°C, and the ultrasonic power is ultrasonicated for 8 minutes; Add 0.6% (w / v) glycerin and 0.5% (w / v) oolong tea polyphenols to the material liquid, add 0.6% (w / w) chitosan, 0.3% (w / w) sodium alginate, roll After compression molding, it is dried to obtain an edible wrapping paper using wheat bran dietary fiber as a raw material.

Embodiment 2

[0015] Example 2: After pulverizing the wheat bran dietary fiber, the particle size range is 200 mesh, and it is mixed with water to make the concentration of the material liquid reach 12% (w / v), the temperature is 40°C, and the ultrasonic power is ultrasonic for 12 minutes; Add 0.8% (w / v) glycerin and 0.4% (w / v) oolong tea polyphenols to the material liquid, add 0.8% (w / w) chitosan, 0.4% (w / w) sodium alginate, roll After compression molding, it is dried to obtain an edible wrapping paper using wheat bran dietary fiber as a raw material.

Embodiment 3

[0016] Example 3: After pulverizing the wheat bran dietary fiber, the particle size range is 300 mesh, and it is mixed with water to make the concentration of the material liquid reach 15% (w / v), the temperature is 50°C, and the ultrasonic power is ultrasonic for 8 minutes; Add 0.9% (w / v) glycerin and 0.6% (w / v) oolong tea polyphenols into the material liquid, add 0.9% (w / w) chitosan, 0.5% (w / w) sodium alginate, roll After compression molding, it is dried to obtain an edible wrapping paper using wheat bran dietary fiber as a raw material.

Abstract

The invention relates to a method for preparing edible packing paper by using wheat bran dietary fiber as a raw material, which comprises the following steps of: crushing the wheat bran dietary fiber to the granularity range of 200 to 300 meshes, mixing the crushed wheat bran dietary fiber and water to make the concentration of the solution reach 8 to 15 percent (w/v), performing ultrasonic treatment for 8 to 15 minutes under the condition of 300 to 600W, adding glycerol, oolong tea polyphenol, chitosan and sodium alginate into the solution, rolling, molding, and drying to obtain the edible packing paper using the wheat bran dietary fiber as the raw material. The edible packing paper prepared by the method has exquisite texture, light yellow color and no special odor, and is suitable for inner packages of instant noodle spices and seasonings; and the edible packing paper can be dissolved by soaking into hot soup, so the edible packing paper is convenient and has certain nutritional value.

Description

Technical field [0001] The invention relates to a preparation method of edible packaging paper, in particular to a preparation method of edible packaging paper using wheat bran dietary fiber as a raw material. Background technique [0002] With the rapid development of social economy and the increasing public awareness of green consumption, edible packaging has become the main trend in the development of the world's food industry and the main direction of the future development of the food packaging industry. The research and development of edible packaging materials has received extensive attention from the international community. Edible packaging materials have a long history, such as "tofu skin" and "glutinous rice paper" for packaging meat and vegetables in ancient my country, and gelatin-based film in Australia, but compared with synthetic polymer materials, there are still various limitations in performance. [0003] As a new packaging material, edible packaging paper has h...
