2. Generally, the shelf life of sweet bread and toast (excluding stuffing) (such as milk toast, pineapple sweet bread and fancy milk bread) is 2-3 days, and it is better to put it in the refrigerator for no more than 4 days.
3. The shelf life of stuffed bread and stuffed toast (such as bean paste roll bread and ham and cheese toast) is 2-3 days or 1 day, and it is better to put it in the refrigerator for no more than 3 days.
During the baking process of bread, the starch linear segment in flour has aged, which is the reason why bread has elastic and soft structure. With the extension of storage time, the linear part of amylopectin in bread slowly associates, which makes the soft bread gradually harden. This phenomenon is called "aging".
The speed of "aging" is related to temperature. At low temperature (above freezing point), bread will age faster, but after being put in the refrigerator, the degree of hardening will come faster.
