The release status of previous versions of this document and the documents it replaces are as follows. --- This document was first released in.2009; --- This is the first revision.IntroductionWith the rapid development of the enzyme preparation industry, the types of enzyme preparations are developing towards diversification, and the product quality has been raised to a new level. There has been considerable progress and development in both techniques and varieties. The formulation of GB/T 23527 "Quality Requirements for Enzyme Preparations" is the product quality and quality requirements for enzyme preparations. The standardization and standardization of detection methods is the basic work to standardize the order of the enzyme preparation and related products industry and promote the development of the industry. GB/T 23527 "Quality Requirements for Enzyme Preparations" is proposed to consist of four parts. --- Part 1.Protease preparations; --- Part 2.Lipase preparations; --- Part 3.α-amylase preparation; --- Part 4.Immobilized glucose isomerase preparation. With the product innovation and development of the protease preparation industry, according to the industry product research and collection of product categories, in addition to microbes covered by the original standard Protease products derived from biological fermentation, as well as plant tissue extraction products such as papain, bromelain, and ficin Pepsin, trypsin and other animal tissue extraction products. In addition, according to the product development needs of domestic and foreign detection method industries, in this revision In, the determination conditions of GB/T 23527-2009 enzyme activity determination method were updated and improved, and the micro-colorimetric method was added. Quality requirements for enzyme preparations Part 1.Protease preparations1 ScopeThis document specifies the product classification, requirements, inspection rules, marking, packaging, transportation and storage of protease preparations, and describes the test method.
