Embodiment 1

[0031] image 3 Shown is the embodiment of the present invention—a production process flow diagram of alcohol-extracted monascus red pigment. Such as image 3 As shown, the traditional fermentation medium was used to inoculate Monascus strains for liquid submerged fermentation; the fermentation liquid was filtered with an inorganic ceramic microfiltration membrane with a filtration accuracy of 0.2 microns; after most of the fermented mother liquid was removed, a certain amount of 70% to 80% concentration of ethanol to break the skin for a period of time; then filter through an inorganic ceramic ultrafiltration membrane with a filtration accuracy of 0.05 microns to obtain the permeated clear liquid, and a small amount of concentrated liquid, and then use conventional filtration to recover the filtrate , the filter residue is discarded, the clear liquid of membrane filtration and the clear liquid of conventional filtration are merged as product clear liquid; the filtrate is con...

Embodiment 2

[0033] Figure 4 Shown is the production process flow chart of dihydric extraction of monascus red pigment according to the embodiment of the present invention. Such as Figure 4 As shown, the traditional fermentation medium was used to inoculate Monascus strains for liquid submerged fermentation; the fermentation liquid was filtered with an inorganic ceramic microfiltration membrane with a filtration accuracy of 0.2 microns; after most of the fermented mother liquid was removed, a certain amount of A large amount of hot water at 80-100°C was extracted for a period of time; then filtered with an inorganic ceramic ultrafiltration membrane with a filtration accuracy of 0.05 microns to obtain the clear liquid, and a small amount of concentrated liquid was recovered by conventional filtration, and the filter residue was discarded. In addition, the clear liquid of membrane filtration and the clear liquid of conventional filtration are combined as the product clear liquid; the filt...

Abstract

The invention provides a technological method for producing monascus red pigment by adoption of the whole membrane technology. The method comprises the following steps: a monascus strain is inoculated into the prior fermentation medium for liquid submerged fermentation; an ultrafiltration membrane or a micro-filtration membrane is used for filtering a fermentation broth most of which is removed, and then ethanol or hot water or another solvent is added into concentrated solution for leaching; an ultrafiltration membrane or a micro-filtration membrane is used for filtering a leaching liquor, and clarifying solution is obtained; a nano-filtration membrane is used for concentrating and removing partial water and ethanol or water; as for alcohol extraction of the monascus red pigment, concentrated feed is distilled and a small amount of ethanol is removed, and then finished products are obtained after mixture and spray drying of the concentrated feed; and as for water extraction of the monascus red pigment, the finished products are obtained after mixture and spray drying of the concentrated feed. The method selects the ultrafiltraiton membranes or the micro-filtration membranes with different filtration precisions to process the fermentation broth and the leaching liquor and uses the nano-filtration membrane to concentrate the clarifying solution instead of using plates and frames for filtration, dose not require adjusting the isoelectric point, eliminates the influence of chemical medicines, improves the product yield and the quality and the color value of the finished products, and has low energy consumption, low cost, high benefit and high application value.

Description

technical field [0001] The invention relates to a process for producing monascus red pigment, in particular to a process for producing monascus red pigment by a full film method. Background technique [0002] Monascus red pigment is a mixture of various ingredients. Generally, crude products have various components, and their main use is as edible red pigment. [0003] The traditional liquid fermentation method of red yeast red pigment production process is as follows: figure 1 and figure 2 As shown, the process includes: using traditional fermentation medium, inoculating Monascus strains, ventilating for liquid submerged fermentation; after adjusting the isoelectric point of the fermented liquid, passing through plate and frame pressure filtration, washing the filter residue with water, adding a certain amount of 70 % to 80% ethanol or hot water leaching for a period of time, then use a filter press to remove the filter residue, recover the filtrate, and after distillat...
