It is a multifunctional cosmetic adjuvant with bioactivity, is a natural steroid resource of steroid medicine, is a raw material for synthesizing vitamin D3 and artificial bezoar, and is a main raw material for synthesizing electronic liquid crystal.
Lanolin is a multicomponent mixture of ester substances secreted by sebaceous glands and adhering to wool comforters, mainly esters of fatty acids with roughly equal amounts of fatty alcohols, sterols, trimethylsterols, etc. Lanolin contains about 10% cholesterol.
The current methods for extracting cholesterol from lanolin include the following five categories: chromatography, bromination, molecular distillation, supercritical extraction, solvent selective crystallization and compounding. The methods are chemical methods, use various organic solvents, easily generate various byproducts in the reaction process, easily cause environmental pollution, consume a large amount of manpower and material resources if the reaction is carried out, do not conform to the scientific concept of ecological environmental protection, and increase the production cost of enterprises.
The method also comprises a microbial conversion method for preparing the cholesterol, so that the use of organic solvents can be reduced, and the prepared cholesterol has high purity and is scientific and environment-friendly. The production of cholesterol extracted from lanolin is realized by preparing seed culture medium → fermentation culture medium → screening strain → inoculating strain → stirring and fermenting → separation and purification → crystallization → drying to obtain cholesterol.
