中文百科
水活性![]() ![]() 水活性(Water Activity,又称水分活度、水活度,简写Aw)指在密闭空间中,某食品的平衡蒸气压与相同温度下纯水的饱和蒸气压的比值,这个观念跟相对湿度(relative humidity,RH)有关:相对湿度=100 x 水活性。 水活性所量度的是食品中自由水分子的多寡,自由水是指可以被微生物所利用,维持正常代谢活性,得以延续生长及繁殖的水,自由水越低环境对微生物的生长较为严苛。纯水的水活性最高为1.0。由于仅有自由水能被微生物所利用,所以总水分含量无法诠释食品在保藏利用性所代表的意义,食品在等温吸湿曲线中吸湿与脱水过程并非为水活性的变化并非循原路径回复。
英语百科
Water activity 水活性![]() ![]() Water activity or aw is the partial vapor pressure of water in a substance divided by the standard state partial vapor pressure of water. In the field of food science, the standard state is most often defined as the partial vapor pressure of pure water at the same temperature. Using this particular definition, pure distilled water has a water activity of exactly one. As temperature increases, aw typically increases, except in some products with crystalline salt or sugar. |
