â–¡ Bottled water and bottled water are packaged drinking water, as long as they are compliant, they are safe. â–¡ The most worrying about drinking water is microbial contamination. It is recommended to pay attention to hygiene when drinking water. It is best to drink it after boiling. â–¡ Household water dispensers may be contaminated by bacteria during use and need to be cleaned regularly Nowadays, many families use water dispensers to drink water, and some also order some bottled water. However, when it comes to drinking water safety, many people will wonder: Is barreled water safe? How should the water in the water dispenser be drunk? What is the difference between the water of the water dispenser and the pure water and mineral water? Can it be safe and healthy? In general, there are three main sources of water for household water dispensers: bottled water, self-filtered tap water, and tap water. For bottled water, from the perspective of hygiene standards and supervision, the bottled water ordered from the water station and the bottled water bought in the supermarket are actually the same. China's packaging drinking water standards (GB19298-2014) pointed out that both bottled water and bottled water belong to packaged drinking water. Therefore, there is no essential difference between the bottled water and the bottled water that we usually drink, such as pure water and mineral water. It is just a different container. As long as it is a compliant product, it is safe. Filtered water means that some households use tap water to connect tap water, and after filtering and heating, the water is the tap water filtered by the household filter. In addition, some families will use tap water directly to drink and drink. These two kinds of water can be safely consumed as long as they are heated and boiled. However, it should be reminded that in order to drink safe and reliable water, if you buy bottled water, you must go to the regular water station to buy and choose a reliable brand; if you are filtering your own tap water, you must choose a quality-assured filter device. And replace the filter element regularly; if you are drinking tap water, it is best to drink it thoroughly after each time. So, can you drink cold water without heating? Can you drink warm water without boiling? The greatest risk to public health in water is microbes. Microorganisms are mainly derived from the pollution of drinking water by human and animal manure. Feces can be a source of pathogenic bacteria, viruses, protozoa and worms. Therefore, the most important thing to worry about drinking water is the microbiological risk. For the bottled water that is usually ordered, as long as the product is qualified, it has been treated with disinfection and sterilization. Under the premise of ensuring that the water dispenser is hygienic, in general, there is no safety problem when drinking directly. If the water dispenser uses tap water or tap water filtered through a household filter, it is not necessarily a safety issue because it is usually sterilized by a water plant. However, there may be contamination during tap water transport, so it is best to drink before drinking. So, if you heat the water slightly to warm water? In fact, if the heating temperature and heating time are not enough, there may still be microorganisms that survive in the water, and direct drinking may also pose a safety risk. In fact, some foreign countries, such as the United States, require drinking water safety education in the community to remind people to drink boiled water in order to better ensure safety. So strictly speaking, cold water without heating and warm water without sufficient heating are safe. It should be pointed out that the water dispenser is not always hygienic. In the course of use, the water dispenser may also breed bacteria, and there may be a safety risk if it is not cleaned for a long time. There have been many cases of poisoning caused by drinking water in our country. In general, the pollution in drinking fountains mainly comes from two aspects: First, when used, microorganisms such as bacteria and viruses may enter the water dispenser with the air. Moreover, dust or the like existing in the air itself may enter the water dispenser and become a "hotbed" for the growth and reproduction of microorganisms such as bacteria. Second, there are some dead corners in the area where the base of the water dispenser is in contact with the barrel. If it is not cleaned for a long time, it will become a zone for the growth of microorganisms such as bacteria. So, how often should the water dispenser at home be cleaned? It is difficult to give a clear deadline. Because each household uses a different water dispenser, the health status at home is different. Some people are very clean at home, and they usually pay attention to hygiene. Maybe the water dispenser can be kept hygienic for a long time; but some people may not pay much attention to hygiene, so it is much cleaner. Shanghai has investigated the health status of public drinking fountains on campus. It was found that after 1 month to 2 months of disinfection of the campus water dispenser, the microbial indicators exceeded the standard. The total number of colonies and coliforms exceeded. Although these are not pathogenic bacteria, they do not necessarily pose a safety risk, but they also remind us that the water dispenser is still very prone to bacteria. Therefore, every 1 month to 2 months, usually clean the water dispenser. As for the specific cleaning methods, different drinking water opportunities are different and are usually attached to the instruction manual of the water dispenser. Therefore, it is recommended that you follow the steps in the instructions to regularly disinfect the dispenser.

Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.

There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.
