First, store food correctly.
How to preserve food has always been a concern of every family, and it is also a headache. Some foods can be preserved for a long time if stored properly. Some foods go bad before eating, or bacteria grow because of the pollution of other foods, which leads to discomfort after eating, which is mainly caused by improper storage. So, what problems should we pay attention to when storing food?
Preservation of fruits. Remove dust and dirt from the skin, clean it up, wrap it in a porous plastic bag and put it in the lower layer of the refrigerator or in the shade. Eat fresh, because the longer you store it, the more nutrients you lose. Most fruits are eaten raw and should be eaten immediately after peeling.
Preservation of fish and meat. Wash and drain the meat, put it in the refrigerator within a day or two, and put it in the freezer if it is not eaten immediately, but it should not be stored for too long. Before freezing meat, shred, cut into pieces and chop it according to the needs of cooking, put it in a fresh-keeping bag and put it in the refrigerator. Because the meat needs to be thawed and cut before cooking, it is not only troublesome but also easy to affect the quality. Fish should be stripped of scales and gills, rinsed, drained, wrapped in fresh-keeping bags and placed in the frozen layer of the refrigerator. If you eat it that day, put it in the refrigerator first. Fish should be washed before cutting and thawed in refrigerator or microwave oven. Thawing at room temperature is easy to be contaminated by bacteria. Don't freeze thawed food again.
Preservation of vegetables. After removing dead leaves, dust and dirt, wrap them in porous plastic bags or paper bags and put them in the lower layer of the refrigerator or in the shade, and keep them fresh while eating.
Preservation of beans, eggs and dairy products. Dried beans should be stored in dry and sealed containers. Tofu and dried tofu should be cleaned with cold boiled water, put in the lower layer of the refrigerator and eaten as soon as possible. Eggs, clean up the dirt on the eggshell and put the blunt end up on the egg rack in the refrigerator. Fresh milk should be stored in the refrigerator below 5℃.
Preservation of grain. Put it in a closed and dry container and put it in a cool place. Don't store it for too long or put it in a damp place to avoid mildew and toxins.
Second, do what you can, and put an end to big eyes and small bellies.
Food waste is a serious problem in today's society, which will bring great harm to society, resources, environment and people's physical and mental health. Especially for a country with a shortage of per capita resources like ours, the problems caused by waste are more serious.
It is estimated that the total amount of food wasted in China can provide about 8 million tons of protein and 6.3 million tons of fat every year. Most of these wasted foods have not expired or are even intact, and there are leftovers. Among them, 90% consumers don't realize how much food they throw away every year. People always buy a lot with big eyes and small stomach, and then throw them away after eating. It not only wastes food, but also wastes money to some extent. Moreover, the huge food waste has also increased the amount of domestic waste and caused some damage to the living environment. The environmental problems caused by food waste are far greater than shopping bags, because the food supply chain will emit carbon dioxide, and the methane released by food decomposition is also a greenhouse gas.
In order to avoid wasting food, people should make a family diet plan carefully. For example, give your family a reasonable amount of food and cook in moderation. For leftovers, if they are in the best eating period, it is best to put them in the refrigerator to prolong the eating time and reduce unnecessary waste. Draw up and stick to your own shopping list, reduce the amount of shopping every time, and avoid unnecessary waste caused by buying too much food.
Third, properly handle kitchen waste.
Kitchen waste is a kind of solid waste produced in people's daily consumption process, which is the general name of surplus food abandoned by families, hotels, restaurants and restaurants of institutions, enterprises and institutions. Compared with other garbage, kitchen garbage has the characteristics of high water content, high organic matter, high oil content and high salt content, and is perishable. The main treatment method is landfill, which will cause land waste, malodorous gas and leachate. With the increasing of kitchen waste in China, environmental problems are becoming more and more serious. But as long as each of us treats kitchen waste correctly, many problems in garbage disposal will be eliminated, and the pollution and secondary pollution caused by these wastes will be alleviated to some extent.
First of all, kitchen waste can be collected separately and treated separately, which can reduce the final treatment capacity and treatment cost of waste. According to statistics, 1 ton of kitchen waste can produce 0.3 tons of high-quality fertilizer after biological treatment. So how should we classify it? Classify kitchen waste into recyclable and non-recyclable categories. Unrecoverable rice, pasta and expired oily and salty foods can be used for raising pigs, while raw vegetables, fruits, peels, bagasse, tea residue, leaves and shells without oil and salt can be used for composting, and these two kinds of garbage can be sealed in plastic bags. Minimizing the soup in the garbage can reduce the pressure of garbage disposal.
Second, use garbage disposal. The available plant kitchen waste can be processed into organic fertilizer, which is a good fertilizer for flower cultivation.
In a word, as long as we are conscientious people, we don't litter casually, do a good job of sorting garbage and try to reduce the amount of garbage, we can reduce some burdens for our living environment.
