Preparation process of bamboo paper for food packaging

Abstract

The invention relates to a preparation process of bamboo paper for food packaging. The invention aims to solve the problem that paper in the prior art contains considerable ash and the like and is notsuitable for food packaging. According to a technical scheme in the invention, the preparation process comprises the following steps: S1, stacking bamboo materials for about 40 days to 2 months afterearlier-stage treatment, and then cleaning the bamboo materials with mountain spring water; S2, fermenting the cleaned bamboo materials in a fermentation box, wherein a low-temperature state is keptin the fermentation box for constant-temperature fermentation; and S3, cleaning and pounding the bamboo material fermented in the constant-temperature fermentation box to prepare paper pulp, thereby preparing the bamboo paper for food packaging. The preparation process has the effects that pollution sources can be effectively removed through constant-temperature fermentation, and the raw materialsare kept in the overall optimal fermentation state and are subjected to constant-temperature fermentation and then to sufficient soaking and swelling with spring water so as to separate ash, extracts, a part of pectin and the like out one by one, so the situation that the quality of paper products is affected due to the fact that the ash is too high is avoided, pollutant residues are reduced, andfood pollution is reduced.

Description

technical field [0001] The invention relates to a bamboo paper preparation process and technology. It belongs to the application of papermaking technology in the aspect of new paper types in the bamboo industry chain, and in particular relates to a preparation process of paper for food packaging. Background technique [0002] The main components of bamboo are water, ash, extract, pentosan, pectin, lignin, and cellulose. Ash is the inorganic matter left after the substance is burned at high temperature. Excessive ash content is extremely harmful to food and human body. hazards. Traditional hand-made paper, according to the oldest method, can effectively remove impurities and harmful substances throughout the process to ensure that paper products can be preserved for a long time without pollution. For example, through lye cooking, lignin can be destroyed and degraded to form soluble substances, so as to achieve elimination. For example, through microbial fermentation proces...

Problems solved by technology

However, these traditional methods are highly artificial, and the processing of many raw materials depends on body sensation, hand feeling, eye view, and experience, so the quality of the final raw materials used in production varies.
