Embodiment 1

[0027] [Example 1] Preparation process of vegetable waste as raw material edible wrapping paper of fruit and vegetable dietary fiber

[0028] (1) Raw material collection and selection

[0029] Collect leftovers after vegetable processing, wash and remove impurities. In this example, leftovers after processing vegetables such as bamboo shoots, Chinese cabbage, celery, and beans are selected, and there is no need to classify raw materials.

[0030] (2) Segmentation

[0031] Cut the vegetable scraps into small pieces about <1cm×1cm.

[0032] (3) Beating and refining

[0033] The beater beats for 3 minutes and refines for 5 minutes to beat the fruit and vegetable tissue into a slurry, expose the fibers, and make the edges of the fibers smooth.

[0034] (4) Dietary fiber extraction

[0035] The raw materials after beating were taken, mixed with an equal volume of NaOH with a concentration of 6%, and cooked at 100° C. for 60 minutes. After cooking, use a 120-mesh sieve to filt...

Embodiment 2

[0046] [Example 2] Preparation technology of fruit and vegetable dietary fiber edible wrapping paper with apple pomace and vegetable pomace as raw materials

[0047] (1) Raw material collection and selection

[0048] Can collect apple pomace and vegetable pomace, add water to stir, sift to remove impurities.

[0049] (2) Beating and refining

[0050] The beater beats for 3 minutes, and refines for 5 minutes, so that the fibers of apple pomace and vegetable pomace are exposed, and the edges of the fibers are smoothed.

[0051] (3) Dietary fiber extraction

[0052] The raw materials after beating were taken, mixed with an equal volume of NaOH with a concentration of 6%, and cooked at 100° C. for 60 minutes. After cooking, use a 120-mesh sieve to filter out insoluble matter, which is dietary fiber. The black liquor can be recycled again, adding 1g NaOH to 100ml black liquor can be reused to extract dietary fiber.

[0053] (4) washing

[0054] The extracted dietary fiber is ...

Abstract

The invention discloses a preparation method of edible fruit vegetable dietary fiber paper, which comprises the steps of material selection, segmentation, beating, dietary fiber extraction, washing, soakage, the delivery of the dietary fiber, sieve arranging, sieve manufacturing and dehydration forming. Alkali process is used for extracting the dietary fiber. The preparation method has the advantages that firstly, the method has good packaging performance, the average thickness of the paper is 0.313mm, the tensile strength is 3.59kN / m, the elongation at break is 9.02 percent and the folding endurance is larger than 200 times; secondly, the dietary fiber is abundant and can be directly eaten; thirdly, the advantages of environmental protection, health, and the like, are provided, foods anddrugs can be directly attached to, and the paper can be widely applied to the civil and military foods and medical packaging field; fourthly, the grade requirement to raw materials is low, thus providing a new way for the deep processing of fruits and vegetables and the effective utilization of resources; fifthly, the secondary recovery problem does not exist in the fruit vegetable dietary fiber editable packaging paper, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a preparation method of edible fruit and vegetable dietary fiber paper. Background technique [0002] During the production and storage of fruits and vegetables, a lot of foreign-grade raw materials will be generated, and a large amount of leftovers will also be generated during the processing process. Usually, these resources will be rotted and lost due to lack of timely and effective use, resulting in huge waste and pollution. . How to effectively utilize these potential resources and realize the comprehensive utilization of resources is an urgent problem to be solved at present. [0003] The comprehensive utilization of secondary resources of fruits and vegetables is now mostly limited to the extraction of nutritional factors such as pectin and dietary fiber, and some are also used as auxiliary materials for animal feed. However, due to the market demand, these processing methods cannot quickly and effectively consume the ...
