First of all, it needs to be clear that walnut buns are pastry foods, which contain fat, sugar and other ingredients and are easily contaminated by microorganisms. Therefore, if you want to prolong the storage time of walnut buns, it is best to keep them in the refrigerator, so as to better maintain their freshness and taste.
But if you really don't have the conditions or want to eat conveniently, you can choose to put the walnut buns in a cool and dry environment. Generally speaking, the storage time at room temperature should not exceed 24 hours, otherwise it will increase the risk of food contamination. Especially in summer, the room temperature is high, which is easy to cause the growth of microorganisms. It is suggested that walnut buns should be stored in a cool place as far as possible.
If you decide to put the walnut package outside the refrigerator, you can choose to put it in a sealed container to prevent the food from absorbing moisture and producing odor. It is suggested that walnut packets should be packaged separately when stored. Do not put multiple walnut packets in one container to avoid mutual influence.
Generally speaking, walnut bags can be stored for 1-2 days without refrigeration, but if you want to keep their best taste and freshness, it is better to refrigerate as much as possible. After all, the first principle of eating is to ensure the health and safety of food.
