Inside a can the food is protected from the things that would make it spoil.These are bacteria,the tiny little living plants that are everywhere around us.Bacteria,sometimes called germs,are so tiny that we can see them only under a microscope.But they are so powerful.
Like all living things,bacteria need food to grow.When they grow they multiply.A few bacteria become many in a matter of minutes.When bacteria settle on food,they make changes in it.These changes are what we call spoiling.
To keep food from spoiling,we must first kill any bacteria that may already be in it.Heat and cooking do this.Next we must keep any bacteria in the air away from the food.So we pack it into cans as airless as we can make them.We seal the cans tight.With no bacteria in the food and no air with bacteria able to reach it,fruits,fish,meat and vegetables will stay unspoiled in a can for years.

把食品放在罐头里面可以防止食品被某些东西破坏.这些东西就是细菌,生活在我们周围的到处都是的微小生物.细菌,有时被称为微生物,小的我们只能在显微镜下才能看到.但是它们是如此地强大.
就像所有的生物一样,细菌需要食物来生长.它们生长的时候,繁殖数以倍增.极少量的细菌在几分钟内就可以变成大量细菌.它们生长在食物上,它们就改变这些食物.这种改变称我们为变质.
为了防止食物变质,首先我们必须杀死食物上的细菌,加热和烹饪可以做到这一点.其次,我们必须使食物远离空气中的细菌.所以,我们把食物放在罐头这种密不透风的地方.我们将罐头密封.食物中没有细菌,也没有带细菌的空气,水果,鱼类,肉类和蔬菜可以在罐头内保鲜多年.
