Embodiment 1

[0026] Put 1 kg of raw penicillin waste residue into a continuous extraction rotary device, add 8 times the mass of dichloromethane and methanol mixed solvent, the volume ratio of dichloromethane and methanol is 5:5, cyclically extract and separate to obtain Product A and filter residue B to be extracted. Concentrate the product A to be extracted at 80°C under low vacuum conditions to obtain an extract; add 15% by weight sodium hydroxide solution to the concentrated product, stir at 60°C for 2 hours for saponification; add hydrogen The amount of sodium oxide solution is 1 / 10 of the concentrated product. Then add No. 6 gasoline to the saponification product, the volume ratio of the saponification product to No. 6 gasoline is 1:30, and let it stand for 2 hours at normal temperature and pressure; the extracted product is concentrated and crystallized at 60°C under low vacuum conditions 3 hours, collected by filtration. Activated carbon was added to the product collected by filt...

Abstract

The invention discloses a technological process for extracting ergosterol with high purity and a feed protein from penicillin waste residue. According to the invention, mycelium in penicillin waste residue is taken as a production raw material, the invention comprises the following steps of distilling, concentrating, concreting, saponifying, extracting and drying and the like for extracting ergosterol and the feed protein. The method has the advantages of simple extracting method with high efficiency and low cost, the extracted products have the characteristics of high purity and good stability, which is suitable for industrial production.

Description

technical field [0001] The invention relates to a process for extracting high-purity ergosterol and feed protein from penicillin waste residue. Background technique [0002] Ergosterol is an important pharmaceutical and chemical raw material, the biggest use is to produce vitamin D2, ergosterol can be converted into vitamin D2 by ultraviolet light. Ergosterol can also be used to produce brassinolides to make biopesticides. [0003] At present, there are two domestic production methods of ergosterol, which are yeast fermentation method and penicillin waste mycelia extraction method. Close to the present invention is the penicillin waste mycelia extraction method. It uses the waste mycelia fermented by penicillin, citric acid or lactic acid as raw materials, and extracts ergosterol through cell crushing, extraction, crystallization and other processes respectively. [0004] The penicillin extraction method utilizes the reaction mechanism of microbial fermentation to produce...
