一、粮食的安全水分储粮环境的相对湿度或粮食的水分活度是粮食能否安全储藏的重要科学指标,这一指标的优点是可以表明粮食上微生物可利用水分的程度。但实际工作中人们更习惯用“安全水分”来判断粮食能否安全储藏。在一定温度范围内,对于能保持粮食稳定状态的水分,存在一个安全值,这个值被称为粮食的相对“安全水分”。安全水分范围内的粮食,
First, food security Water storage grain relative humidity of the environment or grain water activity is an important scientific indicator of the safe storage of food, the indicator has the advantage of indicating the extent of water available to microorganisms on food. However, in practical work, people are more accustomed to using “safe moisture ” to determine whether the food can be stored safely. Within a certain temperature range, there is a safety value for the moisture that can maintain a steady state of food. This value is called the relative “safe moisture” of the food. Safe water within the scope of food,
