Production process for producing natural pigments through microorganisms

Abstract

The invention discloses a production process for producing natural pigments through microorganisms. The production process includes the steps of strain culture, temperature setting, time setting, mycelium inactivation, pigment dissolution, pigment testing, crudely-extracted pigment dissolution, refined pigment purifying and concentration. Compared with the prior art, the process is wide in application range and easy to operate, product quality is good, and production efficiency is high; the process is low in production cost, and more profits are generated; during the production flow of the process, resources are saved, pollution is avoided, and environmental compatibility is good; the process can meet laboratory research requirements and also meet the requirements for enterprise industrial production. The problems, about how to increase the yield, how to purify refined pigments and how to reduce cost, usually generated when the natural pigments are produced through microbial fungi, actinomycetes and bacteria are solved to a certain degree, and the basic problems about the requirements for the stability and safety of the produced pigments are solved to a certain degree.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a production process for microorganisms to produce natural pigments. Background technique [0002] At present, the method of directly extracting natural pigments from plant tissues is generally used to produce pigments at home and abroad. Although the research on the production of natural pigments by microbial culture has already begun, and results have been applied to human production and life. However, due to the wide variety of microorganisms, the ever-changing biological characteristics, and the complex components and diverse properties of natural pigments, whether it is laboratory research or production applications, different extraction and production processes are generally used for natural pigments with different sources and properties. Therefore, up to now, there is no uniform process standard applicable to most pigment-producing microbial strains at home and abroad for the...

Problems solved by technology

However, due to the wide variety of microorganisms, the ever-changing biological characteristics, and the complex components and diverse properties of natural pigments, whether it is laboratory research or production applications, for natural pigments with different sources and properties, different extraction and production processes are generally used.

Therefore, so far, there is no unified process standard for the production of natural pigments for microbial cultivation that is applicable to most pigment-producing microbial strains at home and abroad.
