Problems solved by technology

However, for manufacturers, only purchasing coconut water does not use storage, transportation and subsequent processing, so in fact, it is usually still purchased in the form of coconuts, but after the purchase, the coconut shells, coconut shells and coconut meat are all discarded. It is wasteful and pollutes the environment
At present, there is no technology that can use the whole coconut fruit to produce and process products

Embodiment 1

[0026] Embodiment 1: Preparation of microcrystalline cellulose with whole coconut fruit

[0027] Take fresh coconut raw materials, open holes in the coconut to separate the coconut water and the remaining coconut shell, coconut shell and coconut meat; then add an appropriate amount of sucrose, beef extract and sodium dihydrogen phosphate to the coconut water and then sterilize at high temperature to obtain bio-fiber Vegetable fermentation medium, after inoculating Acetobacter xylinum with an inoculation amount of 8%, fermented at 28°C for 10 days to produce a biocellulose gel film by the static shallow plate culture method, and the biocellulose gel film was separated and washed repeatedly to remove residues After the culture medium components and bacteria, the biocellulose gel is dehydrated and crushed into biocellulose powder for use; then, the remaining coconut shell, coconut shell and coconut meat after separating the coconut water are mechanically crushed, added water and m...

Abstract

The invention relates to a method for producing microcrystalline celluloses by using coconut whole fruit as raw materials. The method using the coconut whole fruit as the raw materials comprises the following steps: fermenting coconut water so as to produce biological cellulose gel, and then drying and crushing so as to obtain biological cellulose powder; by using the rest of coir, coconut shells and coconut flesh as raw materials, crushing, grinding into thick liquid, degreasing, oxidizing, and drying to obtain coir, coconut shell and coconut flesh dry powder; mixing the biological cellulose powder with the coir, coconut shell and coconut flesh dry powder, and carrying out acid hydrolysis, washing, drying and grinding to obtain the microcrystalline cellulose products. The method has the advantages that the coconut water, the coir, the coconut shells and the coconut flesh are utilized to the maximum degree, and no waste is generated; the coir, the coconut shells and the coconut flesh which contain more impurities are pretreated by using a hydrogen peroxide screw extrusion method, and the microcrystalline celluloses are prepared by adopting a two-step acid hydrolysis method, so that needless components in the coir, the coconut shells and the coconut flesh can be removed, and the microcrystalline cellulose products with excellent quality are obtained.

Description

[0001] technical field [0002] The application relates to a method for producing microcrystalline cellulose, in particular to a method for producing microcrystalline cellulose with whole coconut fruit as raw material. [0003] Background technique [0004] Microcrystalline cellulose (MCC) is a kind of ultrafine cellulose, which is usually a granular dry powder product with a particle size of less than 10 μm formed by reducing the molecular weight to a certain range through acid hydrolysis of natural cellulose. Microcrystalline cellulose, also known as free-flowing crystalline powder, is widely used as an excipient and disintegrant in the field of medicine due to its good disintegration properties. It also has good emulsifying properties for oily solvents, and is used as an emulsifier, thickener, etc. in the food industry. At the same time, it can also be used as a good dietary fiber as a health food additive. The raw materials currently used to produce microcrystalline ...
