食品的腐败是指因微生物繁殖,使其成份变化而不适食用之称。食品本身的酶所引起的变化,如苹果切开后发生的褐变等,一般不称为腐败。这种现象用盐水浸泡即可防止。微生物遍布于食品周围,可从表面逐渐侵入引起腐败。因此,在食品的保存中,应防止微生物污染,抑制微生物的繁殖。 Corruption of food refers to the microbial growth, so that changes in its composition and not suitable for food consumption. Food itself caused by changes in enzymes, such as browning after the apple cut open, generally not known as corruption. This phenomenon can be prevented by soaking salt water. Microbes are found throughout the food and can invade gradually from the surface causing spoilage. Therefore, in the preservation of food, should prevent microbial contamination, inhibit the reproduction of microorganisms.
