If I didn't eat the toast I bought at that time, I would have done it the next day. The way to preserve toast is to put it in a cookie jar or box. But first spread a layer of washed pears on the inner bottom of the box, then put the toast on the pears, and then cover the box tightly, so as to prevent the toast from drying out and keeping fresh.
Toast hardens faster in the refrigerator than at room temperature. Bread is generally not suitable for storage in the refrigerator. The most important function of low temperature preservation is to prevent bread from going bad. The best way to preserve toast is to put it in the refrigerator, because freezing can keep the moisture of toast itself. Toast loses water if it is kept in the refrigerator for too long.
Whether a kind of toast is suitable for storage at room temperature or low temperature should be considered from the following aspects: First, whether preservatives are added to toast and whether the packaging materials used are waterproof? If these two points are consistent, they can be stored at room temperature and are not easy to deteriorate; Second, there is not much sugar and oil on toast. If it is fresh milk toast or toast with stuffing such as meat and eggs, it is best to keep it in the refrigerator, otherwise it will go bad easily. The third is to see how long the bought toast lasts. If it is more than three days, it must be put in the refrigerator.
