Food safety.
As the old saying goes: "The people take food as the sky, and food is the first thing". Food safety is no trivial matter, a grain of rice and a table meal affect thousands of households, and it is related to the health and life safety of the people. How much do you know about food safety?Let's take a look at this "safety on the tip of the tongue".
1. What is food safety?
Food safety means: "refers to food that is non-toxic, harmless, meets the nutritional requirements that it should have, and does not cause any acute, subacute or chronic harm to human health." "Simply put, food safety is for human health, life safety, and the higher requirement for food is that it is not polluted by the environment.
Second, food safety tips.
First, when buying food, pay attention to whether the food packaging has a manufacturer, production date, whether the shelf life has passed, whether the food raw materials and nutrients are marked, and you can't buy three no products.
The second is to open the food packaging and check whether the food has its due sensory properties. Do not eat spoilage, rancidity, mildew, insects, filth, unclean, mixed with foreign substances or other abnormal sensory properties.
The third is to pay attention to personal hygiene, wash hands before and after meals, wash and disinfect your own tableware, do not use unclean containers to hold food, and do not litter to prevent mosquitoes and flies from breeding.
Fourth, eat less fried and fried foods.
3. Five elements of food safety.
First, keep it clean: wash your hands frequently, and clean the tableware, kitchenware, and kitchen environment.
The second is to separate raw and cooked: raw and cooked food should be separated, and the kitchen utensils and containers for processing food should be separated from raw and cooked.
The third is that the food should be cooked and burned thoroughly: cooking should be cooked and burned thoroughly, and it should be thoroughly heated when eaten again.
Fourth, keep food at a safe temperature: store food in the refrigerator after it is cooled, do not freeze and thaw raw meat repeatedly, clean the refrigerator regularly, and do not buy or eat food that exceeds the shelf life.
Fifth, use safe water and food ingredients: choose fresh vegetables and fruits, use safe water, and do not use untreated water. Family.
Fourth, common food safety misunderstandings.
1. Wrap food in white paper. In the production process of white paper, a lot of bleach and corrosive chemical raw materials will be added, although the pulp is washed and filtered, it still contains a lot of chemical components, which will contaminate the food.
2. Wipe the dishes with toilet paper. Laboratories have shown that many toilet papers are not well disinfected, and these toilet papers contain a lot of bacteria due to incomplete disinfection;Even if it is well disinfected, toilet paper can become contaminated during the process.
3. Dry dishes or fruits with a towel. Tap water is often thought to be raw and unhygienic, so it is common to rinse dishes or fruits with tap water and then dry them with a towel. This may seem like a hygienic and careful approach, but it's actually the opposite.
4. Boil spoiled food before eating. Medical experiments have proved that the toxins secreted by bacteria before entering the human body are very resistant to high temperatures and are not easy to be destroyed and decomposed. Therefore, this method of treating leftover food with the heating method is not advisable.
5. Peel off the rotten part of the fruit before eating. Microbiology experts believe that even if the rotten part of the fruit is removed, the remaining part has been passed through the juice to the metabolites of bacteria, and even microorganisms have begun to multiply, and the mold in it can cause human cells to mutate and cause cancer. Therefore, it should not be eaten.
6. Quench your thirst with sweet drinks, and drink drinks before meals. Sweetened drinks contain more than 10% sugar, which makes you feel full after drinking, hindering your appetite during meals. To quench your thirst, it is best to drink plain water, which is not only easy to absorb, but also helps the body to eliminate waste products without increasing the burden on the kidneys.
5. How to clean the residual pesticides on fruits and vegetables.
The first is the water washing and soaking method: first rinse off the surface dirt with water, and then soak it in water for 10 minutes, which can dissolve some pesticides, and rinse it with running water 2-3 times after soaking.
The second is the alkaline water immersion method after cleaning: the organophosphorus insecticide decomposes quickly in an alkaline environment, first rinse the surface dirt, soak it in alkaline water (generally add 5g-10g of alkaline surface to 500m1 water) for 5-15 minutes, and then rinse it with water 3-5 times.
The third is the peeling method: vegetables and fruits with uneven appearance or fine hairs are more likely to be contaminated with pesticides, so peeling off the skin is a better way to remove residual pesticides.
Fourth, storage method: pesticides can be slowly decomposed into harmless substances over time, so the fruits and vegetables that are easy to preserve can be stored for a certain period of time to reduce pesticide residues.
Fifth, the heating method: carbamate insecticides accelerate their decomposition with the increase of temperature. In this method, the surface contaminants are washed with clean water, put in boiling water for 2-5 minutes to remove them, and then rinse with clean water 1-2 times.
Sixth, sun exposure: vegetables dried by sunlight have less pesticide residues.
