Preparation method of pancreatic enzyme powder

Abstract

The invention provides a method for preparing pancreatic enzyme powder. The method comprises the following steps of (1) collecting pancreas; (2) preserving the pancreas at a low temperature; (3) carrying out thawing, impurity removing and mincing; (4) extracting the pancreas so as to obtain pancreas slurry, and filtering by utilizing a frame filter press, so as to obtain an extracting solution; (5) adding ethanol into the extracting solution, standing, filtering by utilizing the frame filter press, and collecting a filter cake; (6) washing and centrifuging the filter cake to obtain sediments; (7) drying the sediments in vacuum and crushing, so as to obtain the pancreatic enzyme powder. According to the method, the bovine pancreatic enzyme powder accordant with a Mohammedanism rule is provided, and the market blank is made up; a method for preparing the industrial pancreatic enzyme powder by virtue of pig pancreas is technically improved. The method has the advantages that the production cost is low, the pollution to a final product and the environment is avoided, and the production security is greatly improved; the operation process is simplified, the consumed time is short, the time for preparing each batch of product only lasts for 45-48 hours, and the method is easy to industrialize. The product prepared by utilizing the method has the advantages that three enzyme activities are high and the yield reaches 11.0%.

Description

technical field [0001] The invention belongs to the technical field of biological pharmacy and food processing, and in particular relates to a preparation method of pancreatin powder. Background technique [0002] Pancreatin is widely found in the pancreas of pigs, cattle, sheep and other animals, and its main components are trypsin, pancreatic amylase and pancreatic lipase. It is a digestive aid drug recorded in the pharmacopoeias of many countries in China and the world, and it is also the main raw and auxiliary material in the biopharmaceutical and food industries. However, at present, pancreatin is mainly extracted from pig pancreas in the domestic and foreign markets, which does not comply with Islamic law and is halal. The lack of pancreatin powder has seriously restricted the development of drugs and food products suitable for the Muslim group. Gansu has the advantage of rich pancreas resources and good pancreatin production raw materials in line with Islamic law. If ...

Problems solved by technology

[0003] The traditional pancreatic enzyme extraction process mainly adopts organic solvent precipitation method and salting-out method, and the solvents used such as acetone and ether are volatile and flammable; the chemicals such as ammonium sulfate and sodium sulfate used cause environmental pollution, resulting in high production costs and high product yields. The rate is low, which has a great impact on the enzyme activity, and there are serious safety hazards in production, which will cause great damage to the health of workers.
