It is defined as the ratio between the vapor pressure of water in a substance and the vapor pressure of pure water at the same temperature and is expressed as a dimensionless value between 0 and 1.\u003c\/p\u003e\n\u003cp class=\"gt-block\"\u003e\u003cstrong\u003eWhy is the aw value measuring device important for food?\u003c\/strong\u003e\u003cbr\u003eWater activity is an important factor in food preservation and quality control. Foods with high water activity, such as Fresh fruits and vegetables, for example, are more susceptible to spoilage and deterioration because the water in the food provides an ideal environment for microorganisms to grow. In contrast, foods with low water activity, such as B. Dried fruit, can be kept much longer, since the low water activity makes it difficult for microorganisms to grow.\u003c\/p\u003e\n\u003cp class=\"gt-block\"\u003e\u003cstrong\u003eCan the aw value measuring device also be used for meat?\u003c\/strong\u003e\u003cbr\u003eYes, that humimeter RH2 In any case, the aw value measuring device is used for meat.

Water activity indicates the amount of water that is biologically available for microorganisms such as bacteria, fungi, or similar. Each type of microorganism has a minimum water activity value below which no growth is possible. The higher the aw value of a food, the more perishable it is. Bacteria typically require a water activity of over 0.98, but significantly lower water activity of up to 0.6 can be tolerated by extremely halophilic bacteria, for example.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThe moisture analyzer has a measurement range of 0.01 aw to 1 aw with high accuracy of ±0.03 aw. The measuring attachment is magnetic, ensuring that the sample can be measured securely and protected from light. The moisture analyzer comes with 3 sample trays, allowing many food items to be quickly tested for shelf life. Additionally, 2 AAA 1.5V batteries are required to operate the moisture analyzer.
