Problems solved by technology

At present, the use of bananas in the banana processing industry only stays in the utilization of the pulp, and the banana peels, which account for 30%-40% of the mass of bananas, or 3.6-4.8 million tons, are usually discarded as garbage, resulting in waste of resources.

Abstract

The invention relates to an environmentally-friendly bio-cellulose mask matrix and a preparation method thereof. The environmentally-friendly bio-cellulose mask matrix is prepared by the following method: 1) taking fresh clean banana peel, adding water and crushing the mixture in a crusher into pulp, conducting aerobic fermentation and filtering to obtain a desired banana peel extract; 2) using the banana peel extract as a medium, moving the medium into a mold, inoculating gluconacetobacter xylinus and culturing to obtain a bio-cellulose mask matrix. The banana peel is developed and utilized as the main nutrient in the microbial culture medium innovatively, fully exploits the potential value of the banana peel, and utilizes waste resources to reduce waste of resources and turn the waste into treasure. The production process can effectively reduce the energy consumption and environmental pollution in the existing mask production process, and create higher economic benefits.

Description

Technical field [0001] The preparation of the bio-cellulose facial mask substrate by using banana peel fermentation in the present invention belongs to the reuse of waste gas in the fruit processing industry in the microbial fermentation industry, and the produced bio-cellulose facial mask substrate can be used as a raw material for daily cosmetics. Background technique [0002] Bacterial cellulose (BC for short) is an extracellular product produced by microorganisms such as Acetobacter and Salmonella. It is a type of linear polymer synthesized by microorganism fermentation. BC has the same chemical composition and basic composition as plant-derived cellulose. Both are polymerized by D-glucopyranose through β-1,4 glycosidic bonds. It is a natural polymer with excellent biocompatibility and degradability. Things. Different from the structural components of general plant-derived cellulose mixed with impurities such as hemicellulose and lignin, BC has a higher chemical purity due t...
