“不含防腐剂”不含防腐剂,可没说不含有其他食品添加剂。很多食品天然就是不用防腐剂的,比如罐头,比如一些含盐和糖极高的食品,还有一些极干的食品如方便面、挂面等。因为罐头已把里面的细菌和芽孢彻底杀灭,同时又密封起来,让外面的细菌进不去。大量的盐和糖也能起到防腐剂的作用。不过,盐和糖含量太高,比含有防腐剂还要糟糕。因为摄入过量盐对健康的危害,要比百分之零点几的防腐剂厉害得多。 “Preservative-free ” does not contain preservatives, can not say without other food additives. A lot of food is natural without preservatives, such as canned food, such as some salt and sugar very high food, there are some very dry food such as instant noodles, noodles and so on. Because the cans have completely killed the bacteria and spores inside, at the same time sealed up, so that bacteria can not get in. A lot of salt and sugar can also play a preservative effect. However, the salt and sugar content is too high, even worse than containing preservatives. Because of excessive intake of salt on the health hazards, than a few tenths of preservatives much worse.
