1, so lively and happy to eat: on holidays, most people like to "grab meals" in restaurants in twos and threes, or have dinner with relatives and friends at home, which is lively and easy to exchange feelings. This is unhealthy and does not conform to food hygiene, especially in this extraordinary period, it is best to implement a separate meal system. The practice of sharing meals is the responsibility and respect for others and their own lives and health.
2. Wrap food in white paper: Some people like to wrap food in white paper because it looks clean. But in fact, in the production process of white paper, many bleaching agents and corrosive chemical raw materials will be added. Although the pulp is washed and filtered, it still contains many chemical components, which will pollute food. As for wrapping food with newspapers, it is even more undesirable, because when printing newspapers, a lot of ink or other toxic substances will be used, which is extremely harmful to human body.
3. Disinfect the tableware with wine: Some people often wipe the tableware with white wine, thinking that this can achieve the purpose of disinfection. As we all know, the alcohol used for disinfection in medicine is 75%, while the alcohol content of general liquor is mostly below 56. After all, liquor is different from medical alcohol. Therefore, wiping bowls and chopsticks with white wine can not achieve the purpose of disinfection at all.
4, the rag is not cleaned in time: experiments show that after using a brand-new rag at home for a week, the number of bacteria will surprise you; If you are in a restaurant or a food stall, the situation will be even worse. So clean the table thoroughly before wiping it with a rag. The dishcloth should be boiled and disinfected with boiling water every three or four days to avoid harm to health caused by improper use of the dishcloth.
Ways to buy cold drinks.
1. Look at the packaging: the product packaging is tight and complete, the trademark content is complete, and the product name, factory name, address, net weight, main components, production date and shelf life are clearly visible.
2, look at the color: the color of the product should be consistent with the name, if its color is too bright, it may be caused by adding too much pigment, do not buy and eat.
3. Smell: The fragrance of the product should be consistent with the product name, and it should be soft, pungent and tasteless. If there is an odor, it means it has deteriorated.
4. Taste: The taste of the product should be sweet and sour, and there should be no bitterness, astringency or alcoholic taste (except alcoholic beverages).
5. Observe the juice: the product should be clear and transparent, without impurities, turbidity and precipitation. If the beverage is found to be layered, flocculent or a large number of precipitates can not be stirred, it is a significant sign of deterioration and cannot be drunk. In addition, if you eat a lot of cold drinks after exercise or on an empty stomach, it will strongly stimulate the gastrointestinal tract and the heart, causing sudden convulsions, leading to various enzyme and chemical reactions disorders and menstrual disorders in women.
How to identify dairy products
Milk and its products are ideal foods for the elderly, women, children and patients, but they are easy to deteriorate. The identification of hygienic quality of milk and dairy products can be carried out in the following ways.
Fresh milk: a white or yellowish uniform suspension with normal sensory characteristics, without clots and impurities, with a slightly sweet and unique fresh milk aroma. If the color of milk is found to be gray, yellow or red, and it has a sour taste, it means that the milk has gone bad and cannot be drunk.
Milk powder: The normal sensory characteristics should be light yellow powder with small and uniform particles, without quick knot and peculiar smell. When buying milk powder, check whether the packaging is tight, because if it is not tight, milk powder will deliquesce easily. In addition, we should pay attention to the shelf life, and the hygienic quality of expired milk powder is not guaranteed.
Yogurt: Ordinary yogurt, with the same color as fresh milk, dense, solid and uniform clots, pure and fragrant lactic acid smell and no bubbles. When the color and taste of milk change, the clot melts and a large amount of whey precipitates, it means that milk has deteriorated and should be discarded and not drunk.
Sweet condensed milk and evaporated milk: normal sweet condensed milk and evaporated milk are even light yellow and sweet. When poured out, the emulsion flows downward in a linear or ribbon shape. If clots, mildew spots, floating fat and peculiar smell are found, it means that the sanitary quality is poor and it cannot be eaten.
