1, shelf food easy to expire
1, olive oil Most olive oil has an expiration date at the bottom of the bottle, but this is only applicable if it is unopened. After the olive oil is opened, if it is stored on the shelf for several months, it is likely to deteriorate and have the taste of fatty acids.
2. Flour If you have been making cakes for a while, the flour at home is likely to have expired. Generally, high-gluten and low-gluten flour can be stored for about 8 months after the "best edible date", and whole grain flour such as whole wheat and rye can be stored for about 6 months. Flour that has passed the shelf life will have some bad smell.
3. Whole grains of unground oatmeal, such as brown rice or quinoa, can be preserved for about 1-2 years, while refined grains, such as breakfast oatmeal, are easy to deteriorate and the shelf life is about 6 months.
4. Spicy seasoning It is delicious to put some spicy seasonings such as pepper and thyme in the dish, but the seasoning also has a shelf life, about 1-2 years. If you are not sure whether the nutmeg or oregano leaves at home are well preserved, you might as well take some in your hand and smell them. If the smell is no longer strong, you can consider replacing it.
5. Nuts and seeds If peanuts, sunflower seeds and other nuts or seeds at home are stored for more than 6 months, they are likely to deteriorate. Nuts or seeds, such as almonds and flaxseed, will be oxidized and deteriorated after being stored for a few weeks, so they should be stored in the refrigerator when bought.
6. Bread crumbs are easy to get wet. Consider replacing bread crumbs after 6 months.
2. Fresh-keeping methods of crabs
Method 1: The crabs stored in the refrigerator are fresh aquatic products, which can be kept for a short time after leaving the water. It is relatively simple to store crabs that can be eaten in about 3 days: choose crabs with strong vitality, tie their feet and doors to reduce the physical consumption of crabs, and then put them in the freezer of the refrigerator and cover them with wet towels for storage. When eating every day, choose crabs with insufficient vitality and sufficient vitality to continue to be preserved.
Method 2: prepare a plastic bucket/basin with a height of 30-50 cm for raising crabs. The inner wall of the plastic bucket/basin is smooth and difficult to escape. Put crabs in, don't fold them; Then add water to half the height of the crab-mainly to keep it moist. You can't bury all the crabs. If the water is too deep, crabs will suffocate due to lack of oxygen. Crabs can be preserved in this way without covering barrels/pots. When the temperature is not high, hairy crabs can be kept fresh for more than 5 days. Foodwang.com Healthy Diet Network
Method 3: Keep crabs in a temporary pond. If you can't eat all the crabs in three to five days, you can't store them in the above way. The best way is to make your bathtub into a temporary pond for crabs to enjoy first: because the walls of the bathtub are smooth, crabs can't escape, and then gently pour them into the bathtub and fill them with water. If crabs stand on their feet, they can breathe on the water and taste a small amount of fish and shrimp according to the storage time and quantity.
Special reminder: If you don't eat it right away, please don't wash it with water, or the crab will die. If the indoor temperature does not exceed 15℃, there is no need to put the refrigerator. Generally, it can be stored for 5-7 days, but the crab will lose weight if it is stored for too long, and the taste will not be affected if it is eaten within 3 days.
