Water activity (aW value) is an important factor affecting the shelf life, color, aroma, and other physical properties of food. It is an important reference for determining whether there is a risk of spoilage in food and a visual basis for controlling microbial production in food. Developed countries such as the United States, Europe, and Japan have incorporated water activity indicators into quality management systems such as FDA, USP, EC, ISO, HACCP, etc., as important indicators for monitoring microbial growth.

Looking back at the introduction of various national food safety management regulations, we deeply feel that the standardization and standardization of conceptual awareness go far beyond the significance of the instrument itself.Food qualitysafetycontrolThe term 'water activity'key metricsIn 1992, the management only targeted export enterprisesNational Import and Export Commodity Inspection BureauproposeMethod for determination of water activity in food (SN 0180-1992)In 2009, a《GB/T 23490-2009 Determination of Water Activity in Foods》National standardpromulgate and implement, markingFurther popularization of food safety regulations.In 2012, in order to fill the gap in the grain and oil standard system and promote the application of water activity in the grain industry, the Beijing Beidouxing Industrial Chemistry Research Institute participated in the national standard "Determination of Grain Water Activity in Grain and Oil Inspection" jointly conducted by the National Grain Administration Scientific Research Institute. It was responsible for the development and verification of water activity experimental plans for grains such as corn, wheat, rice, and soybeans, and jointly drafted and formulated the standard. 《GB/T34790-2017 Grain and Oil Testing - Determination of Grain Water Activity - Instrument Method StandardHow to translate

It will be officially implemented on May 1st, 2018The promulgation of this standard in the grain and oil industry has made standardization management more in-depth and extensive.At the beginning of the application and promotion of Beidou moisture meter in the food industry in 2000, there was a widespread problem that moisture detection relied solely on human visual inspection and manual touchThe ancient way,This situation has deeply impressed us as instrument scientistsworry，traditionalHow can processing methods adapt to the rapidly developing market demand,Strong sense of missionMake Beidou people aware of the practicality and importance of promoting scientific instruments,A new one must be adopteddetectionTheory and TechnologyApplied to food production,After detailed research,Based on the moisture testing technology of Beidou Satellite MS1204, and comparing the advantages and disadvantages of existing detection principles at home and abroad, we have researched and developed

MS2100 Water Activity TestIn 1996, Beidou MS1204 moisture testing technology was awarded the Beijing Torch Program, which is the technical accumulation of several generations of Beidou experts from the Chinese Academy of Sciences.In 2006, the Beijing Beidou Industrial Chemistry Research Institute launched a project in ChinaHBD5-MS2100typeWater activity testerFor over a decade, from being neglected in the initial market to serving numerous food companies both domestically and internationally, in an industry that concerns people's livelihoods,HBD5-MS2100typeWater activity testerAnd also witnessed it from another perspective
