Abstract

The invention relates to a method for preparing natural carotenoid crystals, especially lycopene and beta-carotene by taking microorganism biomasses as raw materials. The method comprises the following steps of: adding an extraction solvent into Blakeslea trispora mycelium, carrying out cell disruption and filtering, and collecting filter liquor; carrying out vacuum concentration on the filter liquor, and recycling solvent to obtain oleoresin; adding a washing solvent into the oleoresin, and washing and filtering to obtain coarse crystals; and drying the coarse crystals and removing residual solvent, thus obtaining the high-content carotenoid crystals. According to the method provided by the invention, the types of the used solvents are few, the use levels of the used solvents are little, the extraction and purification processes are simple, the yield is high, and the method is suitable for industrial production; and the obtained carotenoid crystal product is high in content and good in quality, and can be widely applied to the fields of functional foods, medicines and the like.

Description

technical field [0001] The invention relates to the field of biochemical engineering, in particular to a process for extracting and purifying carotenoids using microbial biomass as raw materials. Background technique [0002] Carotenoids are a class of polyenes that are widely present in plants, animals, microorganisms and algae and contain yellow to dark red polyenes, which have many functions, such as anti-oxidation, anti-cancer, prevention of night blindness, tinting power. Strong wait. As food additives and nutritional supplements, carotenoids have been recognized by FDA, European Community, WHO and other international organizations. In recent years, it has been widely used in the fields of medicine, food, health care products and cosmetics. [0003] Lycopene and beta-carotene are two very important carotenoids, which have strong antioxidant capacity and coloring function. Plants are one of the important sources for obtaining lycopene and beta-carotene, such as tomato...
