If it's fried puffed food, you can microwave it or put it on a radiator. If it's a cracker that's been exposed to moisture, you can freeze it in the refrigerator and it will be cool enough to eat, or you can blow it with a hairdryer for a few minutes, and it will become crispy when it cools down. Most of the food if it is fried food, you can use the oven does not close the door and bake for a while on the crispy, if the other food can be put in the refrigerator to freeze a little bit, the principle of analysis: moisture is because of the humidity of the air, affecting the moisture of the food. The refrigerator is dry, the temperature decreases, the moisture will be in such fried or baked food or snacks are required to be sealed and preserved, if a long time exposed to the air will be damp.
Short time to eat, long time taste will change, the original crunchy will become soft, there are several ways to extend the storage period: large bags of food as much as possible to open the mouth of the smaller, drain the air in the food bag, tightened with a leather band, with a small rope can also be more, palatable, cats love to eat, but not enough nutrients, cats eat too much, will be picky eaters, and the children eat too many snacks will be The same reasoning as a child who eats too many snacks will be picky about food. So when you buy canned food, you must ask the seller, is the snack canned food or staple food head nothing else to eat. At first, I mixed dry food and canned food together for him to eat, and then gradually reduce the canned food, until not to give canned food. He didn't eat and lost weight, and on the third day of the hunger strike he started eating dry food. No more canned food was given after that.
If it is meat, it is recommended to finish it on the same day or seal it well and put it in the refrigerator. If it is summer, it is best to put in the refrigerator in the summer easy to change such as snacks, put the living room for a night, the living room is very clean, few cockroaches and rats, no sealing, I think it is not afraid, if the environment is worse, often have rats, cockroaches, then it is recommended that you do not eat it. Meat general temperature is not high, the environment did not ask me snacks are sometimes not finished eating at night lazy to clean up, directly back to the room to sleep, the next day and then cleaned up, if it is puffed food may be a night on the not crispy. So you still have to develop good habits, eat things that are not finished sealed, the refrigerated on the refrigerated.
