Embodiment 1

[0022] Take the preparation of 1000g of red flesh apple fiber edible wrapping paper as an example, its raw material composition is:

[0023]

[0024] Its preparation method is as follows: First, after drying 50g of red-fleshed apple pomace at low temperature, it is pulverized to 120 mesh with an ultrafine pulverizer, then added to 745g of distilled water, mixed and stirred evenly, and the pulp is homogenized with a high-pressure homogenizer. quality, the pressure is 400bar, and homogenized 3 to 4 times to obtain red-flesh apple fiber pulp; then add 30g cellulase to the red-flesh apple fiber pulp to carry out enzymatic hydrolysis for 1.5h; After dissolving 10% acetic acid aqueous solution, add it to the enzymolysis solution, finally add 102.5g konjac gum and 35g food grade glycerin, stir and mix evenly to obtain a film liquid; heat the prepared film liquid to 100°C, and vacuum degassing for 5 Minutes, and then cast immediately on a glass plate, then dry at 40°C for 1 hour, a...

Abstract

The invention discloses Malus niedzwetzkyana Dieck fiber edible packaging paper and a preparation method thereof. The preparation method for the edible packaging paper comprises the following steps: subjecting pomace obtained after juicing of Malus niedzwetzkyana Dieck produced in Xinjiang Province to drying and superfine grinding; then adding the ground pomace into distilled water, and carrying out homogenization and enzymatic hydrolysis with cellulase; then blending an enzymatic hydrolysis product with chitosan, konjak gum and edible glycerin to form a film forming solution; and subjecting the film forming solution to vacuum degassing, coating, drying and paper peeling so as to the packaging material with stretching and heat-sealing mechanical characteristics. The edible packaging paperof the invention is applicable to packaging of instant foodstuffs like flavoring for instant noodles and hotpot condiments; and since edible packaging paper has the characteristics of edibility, solubility and degradability, the edible packaging paper can be directly eaten, improves nutritional value, can effectively overcome the problem of environmental pollution caused by packaging material, andhas good market prospects and development and utilization value. The edible packaging paper of the invention provides a novel approach for utilization of the pomace of Malus niedzwetzkyana Dieck andprovides experiment reference for research and further industrial production of edible paper packaging materials.

Description

technical field [0001] The invention belongs to the technical field of food processing and packaging, and in particular relates to an edible wrapping paper made of red-flesh apple fiber and a preparation method thereof. Background technique [0002] In the past two decades, "environmental pollution" has become a major threat to human society, and "white pollution" has become a hot topic in environmental protection. How to reduce and control "white pollution" has received great attention. According to statistics, the main sources of white pollution are food packaging, foam-filled packaging, fast food boxes, and agricultural mulching films. With the rapid development of the modern food industry, food packaging materials are constantly updated. The advent of "degradable" food packaging materials has greatly reduced the problem of "white pollution" in the field of packaging materials; among them, edible packaging materials have further promoted It has become a hot spot in the f...
