[Chinese Packaging Network News] The vegetables bought are directly packed in plastic bags and stuffed into the refrigerator; leftovers are put into plastic lunch boxes and stored under refrigeration; meats and seafood are not removed until they are eaten. Plastic products are used to store foods. It is widely used, but it is not only easy for food to lose moisture, nutrition and taste, and the harmful chemical substance of bisphenol A in plastics also poses a threat to human health.
For this reason, the United States is famous for its articles, recommending several storage containers for plastic products to help you retain health.
Save for a long time, with metal and glass containers
If you want to store a variety of foods for a long time, it is most appropriate to use metal or glass containers, such as plexiglass crispers, metal lunch boxes, etc., because they are not afraid of freezing, can block the air, and will not release harmful substances. Regardless of the type of container chosen, the lid seal is very important. It is best to choose a lid with a silicone gasket to avoid air ingress to keep the food fresh. It is best to choose a flat, rectangular container, which is more conducive to put into the refrigerator freezer to save space. It should be reminded that, when freezing liquid food, do not fill the container to prevent the liquid from swelling and breaking the container. When using the glass container to freeze food, you can pour some water on the outside of the container, which can help strengthen the seal and protect the food more. When thawing, first use warm water to open the outer layer of ice and then thaw the food; if using a stainless steel container to store, pay attention to food can not contain salt, soy sauce, soup, etc., otherwise it will dissolve the harmful substances in stainless steel.
Meat wrapped in paper and foil
If you want to freeze large chunks of solid food (such as meat), or package pre-frozen foods, use paper and aluminum foil are good choices. Unbleached, traditional oil papers that are specially used for wrapping foods have good anti-oil, moisture, and moisturizing effects, but they can only be used in the short term when frozen foods are used. In contrast, aluminum foil seals and moisture retention are more advantageous, but it can easily be torn, and if it fails, it will fail. Therefore, after being wrapped in aluminum foil, oiled paper can be added to the outer layer. To avoid waste, aluminum foil and oiled paper can be reused.
Plastic bag, first coated paper
If there are no such containers in the home, you can wash the cans thoroughly, put them in food, fasten the lids, and seal them with tape. If you must use plastic bags, you may wish to take the following measures to minimize the damage: use special food plastic bags, although they are thinner than shopping bags, but they are durable, moisture-proof effect is better, and contain bisphenol A ingredients Less or not; try not to let the food directly touch the plastic bag. You can wrap the food with oil paper first and then seal it in a plastic bag.
According to the editor of China Packaging Network, packaging is the second layer of food. How to make this layer of skin more healthy is a topic worthy of discussion.
