As we all know, water is the source of life, but many people still know only about thirst. In fact, how to drink reliable water and healthy water is a lot of stress, especially in the modern society that is flooded with various concepts of water and water containers. In this issue, this edition invites relevant experts to teach you to drink water correctly.
Burn yourself
Water is cooked for three more minutes
It is convenient and save money to boil water and drink yourself, but in the ointment, the burned water always has a taste, but it also has to “fight†with scale for a long time. How can we win this battle?
Every time the tap water is boiled, it will give a force to the scales on the bottom of the pot and on the wall of the pot. It will fall in the cup and there will be a layer of white foam on it. It will also have a “strange smell†when drinking, especially in the north. common. In fact, this is because water contains too much calcium and magnesium ions and it has a high content of water and minerals, which is vividly called "hard water." Professor Jiang Wei of the College of Food Science and Nutritional Engineering of China Agricultural University pointed out that the main components of scale are carbonates and magnesium salts, which are not harmful to the human body. However, if there is a lot of scale in the kettle, it can easily absorb harmful substances in the water and it is best to remove it periodically. Remove scale, use physical methods more effective, that is, first dry the pot, see the scale dry white, quickly poured into the cold water, due to the principle of thermal expansion and contraction, scale will be a large number of off. You can also try chemical methods - dissolve with acidic substances, such as adding some white vinegar to the pot first, then pour in a lot of water, boil for 20 minutes, and wipe with a soft cloth. If you are in trouble, you may wish to try the famous food expert Wen Yi in the supermarket Amoy baby - "water alkaline filter", can play the dual role of descaling and eliminate odors, "If you still feel water smell, you can put a slice of lemon Go in, or drink tea.†Wen Yi suggested.
If you want to burn the water you feel better and the water quality is safer, don't burn the tap water immediately and let it go for a while. When the water is opened, the lid is opened, and after the water is opened, it waits for two or three minutes to turn off the flame. This can effectively evaporate harmful substances in the water.
Water dispenser
Wash once in two months
Tap water is processed through the filter water dispenser, and the taste is improved a lot. However, some people figure things out and simply drink bottled water. Regardless of the kind of water quality you want to maintain for a long period of time, regular cleaning of the water dispenser is the most important part.
“At present, the drinking fountains in the market have evidence of electrical safety, but they are lacking in terms of hygiene and safety.†Lu Jianguo, director of the comprehensive inspection department of the National Household Electrical Appliances Quality Supervision and Inspection Center of the China Household Electrical Appliances Research Institute, pointed out that at the time of purchase, To get a good deal, we must choose the products of a regular company. On this basis, the dispenser must be regularly cleaned.
Filter-type drinking fountains are mainly cleaned by filters. Using them for a long time, they will accumulate a lot of bacteria and microorganisms, and even grow “mossâ€. It is best to clean it every two or three months. "Generally do not recommend that you dismantle and clean yourself, you should ask a professional to operate it, otherwise it is very easy to damage the circuit, cause the striker to strike, and it will also cause electricity safety hazards." Lu Jianguo said that if your home's water dispenser can filter the entire filter Remove it, must follow the instructions, rinse repeatedly with clean water. Filters are usually replaced once every 1-2 years.
The key to the cleaning of bottled water dispensers is where the buckets come into contact with the machine. When cleaning, remove the bucket first, empty the remaining water in the storage tank, wipe it with a neutral detergent, and then fill it with water, add a special disinfectant, soak for a while, then pour clean water. Rinse repeatedly until the released water does not smell bad.
In addition, regardless of the type of water dispenser, the surface of the body, the inlet, the outlet, and the accumulated water tray must be cleaned and disinfected each time they are cleaned.
Bottled water
Best to drink hot
Bottled water is increasingly appearing in people's lives, and the following three points need to be taken into account when using it.
Pure water with plain water. The most common bottled water is purified water and mineral water. Although impurities and contaminants in purified water have been removed, this water cannot be consumed for a long time. Because of the pure treatment of water, the minerals and trace elements that are beneficial to the human body in water are also removed, especially for the elderly and children. Studies have shown that 30% of calcium and 30% of the body's calcium needs are derived from water. Drinking pure water for a long period of time will not be enough to absorb calcium. The existing minerals in the body will be excreted through the metabolism of pure water. The best way is to drink pure water with boiled water or mineral water to meet the body's demand for minerals.
Drink in a week. The principle of bottled water effluent is to draw water through air pressure. Each liter of water released must have a volume of air corresponding to one liter of bacteria and dust entering the body. Every time the water is changed, a part of the water remains in the sink and a large amount of microorganisms are also produced. Therefore, for safety reasons, bottled water is best served within a week. If there are few people at home, a smaller bucket can be used.
It's best to drink hot. Due to the uneven quality of bottled water, the cleaning and disinfection of the buckets is not strict, making the original safe water unsafe. Therefore, it is best to drink bottled water to boil and then drink, but also to buy a big brand.
Water in water heater cannot be drunk
Some people find it convenient to use the water in the water heater to cook water and cook. This is very undesirable. Because the tap water that enters the water heater will be subject to secondary pollution by the pipe network. Secondly, the water in the water heater is heated repeatedly, and the chlorine that will play a role in disinfection in the water will be reduced, providing favorable conditions for the growth of microorganisms and bacteria in the water storage tanks and pipelines. In addition, many communities are now uniformly supplying hot water. Most of these public hot waters are provided to residents for bathing purposes. They do not meet drinking water standards. It is best not to use boiling water or cooking.
Get up early to give water to the faucet
Tap water in overnight taps and nearby water pipes may be contaminated by metal pipes and attached bacteria. It is not suitable for brushing, rinsing or boiling water for cooking. It is recommended to use the basin to pick up the half-basin water (which can be used to flush the toilet, wipe the floor, etc.) and use it afterwards. Houses that are newly renovated or often not at home, should pay special attention.
Electric kettle stainless steel
Electric kettle boiling water is convenient, but the choice and use also need to pay attention. First of all, to buy quality products, the best choice of stainless steel, boil water more secure. Second, be sure to add boiling water at any time by using an electric kettle. Because the temperature is reduced to a certain degree, it will automatically heat up. When a pot of water is heated repeatedly, the water quality will not be too good.
The boiling water is dried in a glass
The container is very important for the safety of drinking water. After the water is boiled, if you want to cool it, the glass is the safest, followed by the porcelain bowl or the porcelain cup. The plastic container is best not to be filled with boiling water, and not only is it easily deformed, but its harmful substances are also easily dissolved when exposed to heat.
