The refrigerator carries people's expectations for life and yearning for health: milk, eggs, fruits, vegetables, meat, seafood, etc., a wide variety of items are available. But do you know that when using the refrigerator to preserve food, if the storage method is not correct, it will damage the nutrition of the food, but it will cause food poisoning and bacterial infection. For example, "Pregnant women infected with Listeria lead to premature birth" and "Chilled watermelon cross contamination leads to poisoning" are often seen in the newspapers. There are two main reasons why food in the refrigerator can cause poisoning: Improper storage of food in the refrigerator often results in raw and cooked food being mixed, leading to cross contamination and spoilage of food, which in turn causes re-contamination and re-spoilage of food. The temperature of the refrigerator compartment is generally set at 0-5℃. The cooler temperature has a significant inhibitory effect on the reproduction of most bacteria, but some psychrophilic bacteria, such as Escherichia coli, Salmonella typhi, Staphylococcus aureus, Listeria, etc., are still very active. They multiply in large numbers and cause food spoilage. Eating these foods may cause abdominal pain, nausea, and regurgitation at the mildest, vomiting and diarrhea at the worst, and even life-threatening. So, how can we use the refrigerator to ensure that food is nutritious and safe? First of all, let's reduce the burden on the refrigerator. Not all food needs to be stuffed into the refrigerator. Some foods don't need to be: Fruit Unripe tropical fruits such as bananas, mangoes, avocados, pineapples, etc. should not be refrigerated, otherwise it will not only affect the maturity but also easily cause frostbite. For example, bananas will turn black if placed in the refrigerator, so they can be stored at room temperature. Vegetables Green peppers and sweet peppers are susceptible to frostbite when refrigerated; Onions tend to grow roots and become hollow when refrigerated; Refrigerating potatoes can cause them to darken when cooked and have a worse taste; If cucumbers are refrigerated for more than 3 days, the skin will appear waterlogged and the flavor will deteriorate. Refrigerating tomatoes can affect ripeness; Chinese cabbage, carrots, white radish, onions and garlic can be stored for a long time even at room temperature, so there is no need to put them in the refrigerator. Starch Foods such as steamed buns, flower rolls, and bread tend to become dry and hard when refrigerated. High salt and high sugar Biscuits, candies, pickles, ham, bacon and other foods with low moisture content and high sugar and salt concentrations are simply a waste of electricity and space when placed in the refrigerator. Honey has a high sugar content and is prone to crystallization of glucose when refrigerated, affecting the taste; If chocolate is kept in the refrigerator for a long time, the fat will crystallize and affect the taste. Drinking If opened milk powder, tea leaves, and coffee are not properly sealed, they will easily absorb moisture and deteriorate when stored in the refrigerator. Food stored in the refrigerator must also be handled and placed correctly to avoid cross contamination: Vegetables Dispose of dirt and rotten vegetable leaves. fruit Store separately from vegetables. Wrap the cut fruit with plastic wrap and seal it, then store it in the refrigerator. Cut off a layer of the surface before eating. Meat and seafood Fresh meat and seafood are generally refrigerated for a shorter period of time and are more likely to carry pathogenic bacteria on their surfaces. So after you buy it home, please seal it before putting it in the refrigerator, and store it separately from other foods to avoid cross-contamination of bacteria. Eggs Many people wash the eggs before putting them in the refrigerator. Doing so will damage the protective film on the surface of the eggs and allow bacteria to enter the eggs. However, there may be salmonella on the surface of eggs, so after buying them home, seal them in a fresh-keeping box and then refrigerate them. milk Opened milk should be refrigerated within 1 hour on hot days (2 hours on non-hot days). If kept beyond this time, it may go bad and can be thrown away. Beverages, condiments You need to tighten the lid and put it in the refrigerator. Leftovers Food that is not to be eaten for a short period of time should be wrapped in plastic wrap while hot and stored in the refrigerator to avoid bacterial growth during the cooling process. Of course, it is necessary to clean it regularly, preferably once a month. The steps are as follows: first step Unplug the power. Step 2 Take out all ingredients. Step 3 Scrub. You can use refrigerator-specific cleaner or alcohol to carefully wipe the inside and outside, seals, etc., and then wipe dry with a dry cloth. Step 4 Deodorizing. Toilet paper, dried orange peels, lemons, and dried tea leaves are all good at deodorizing. Step 5 The key point is that in daily use, you should also clean out spoiled, wilted, and frozen food in a timely manner to keep the ingredients in the refrigerator fresh. The refrigerator is an important appliance that affects the food safety of every household, so every family’s cook must pay attention to food storage! Source: Youlai Healthy Life |
