Abstract

The invention discloses a monascus mycelium resource comprehensive utilization method. According to the monascus mycelium resource comprehensive utilization method, ultrasonic assistant extraction is adopted to extract monascus pigment in monascus mycelium, optimum extraction conditions of monascus pigment are determined, extraction rate can be increased to 94.01%; acid and alkali treatment is adopted, optimum extraction conditions of crude protein are determined, and extraction rate is increased to 64.3%; direct alkali adding is adopted, optimum extraction conditions of ergosterol are determined, extraction rate is increased to 4.16%; and alkali adding extraction is adopted, optimum extraction conditions of chitosan are determined, and chitosan yield is 2.45%. The monascus mycelium resource comprehensive utilization method is capable of maximizing the utilization of resources, and achieving relatively high economic, social, and ecological benefits.

Description

technical field [0001] The invention belongs to the technical fields of food processing and medicine, and in particular relates to a method for comprehensive utilization of monascus mycelium resources. Background technique [0002] Monascus, which has long been considered to have both edible and medicinal effects, is the main strain that people have long been familiar with for the production of red yeast rice wine and natural red pigment. In recent years, due to doubts about the safety of synthetic pigments, natural pigments have been paid more and more attention, especially Monascus pigments with health functions are more favored by consumers. The production of red yeast pigment by fermentation has the advantages of low energy consumption, simple operation, and low extraction cost. The product is a natural food red pigment with good coloring, stability, safety and non-toxicity. It is an edible natural pigment worthy of vigorous development and promotion. . However, the co...
