After the steamed bread is cooled, put it in the refrigerator as fresh as possible, and it is best to seal it with a fresh-keeping bag when freezing, so that the steamed bread will lose less water, taste better, and avoid cross-contamination with other substances.
Frozen steamed bread should be fully heated before eating, which will reduce the risk of food safety and have less harm to health. However, a refrigerator is not a safe. If steamed bread is left outside for a long time before freezing, it may have been contaminated or deteriorated by mold. If you put it in the refrigerator again, steamed bread will still go bad.
Food preservation method
Steamed bread, rolls, bread and other starchy foods can be stored for 1 day in summer and 2 days in autumn and winter, and then tied up with fresh-keeping bags. If you want to store it for a longer time, you'd better tie the mouth of the fresh-keeping bag and put it in the freezer, so that it can be stored for a longer time. When eating, take it out and freeze it in the microwave oven. The taste is as fresh as ever. ?
Drying and dehydration is a fresh-keeping method to prevent the growth of mold, fermenting bacteria and bacteria by removing water from food, such as drying fruits in the sun to achieve the purpose of fresh-keeping.
Quick-freezing drying is a dehydration process. Food does not need to be preserved or refrigerated. After food absorbs water, it returns to its original state and taste. This method can be used to preserve various foods. When food is frozen in the refrigerator, the air in the refrigerator is pumped out and the ice is evaporated. This process is called quick-freezing drying.
