PH values are still "stealthy". Only 10 kinds of mineral water are labeled with 2 pH values.
the sanitary standard for drinking water, which was jointly issued by the State Ministry of health and the National Standardization Committee, began to be enforced in the whole country on the 1 day of this month. It is understood that in addition to the regulation of drinking water quality from 35 items of the original standard to 106 items, the acidity and alkalinity range of drinking water (PH) should be between 6.5 and 8.5, and it must be marked on pure water and mineral water bottle. On the 5 day, a reporter went to a supermarket in Weihai, such as Da rfat, and found that only 10 of the two mineral water were labeled with pH value.
5 reporters went to several supermarkets in Weihai and found that there were more than 10 kinds of mineral water sold on the shelves. It is understood that the pH value of the natural water of high quality drinking water is between 6.5 and 8.5, but only two of them are labeled as "farmer mountain spring" and "Laoshan". Among them, the pH value of Laoshan mineral water is 7 + 1, and the pH value of farmer's spring is 7.3 + 0.5. The mineral water of Wahaha mineral water, Kangshifu mineral water and Nestle super live mineral water has not been labeled with the pH value of nearly 10 kinds of mineral water. Reporters asked supermarket salesmen that many people were not aware of the implementation of the new rules. "I have heard that there are new regulations, but this does not affect the brand of mineral drinking water that customers choose."
not only supermarket personnel do not understand the new regulations, but few citizens know the new rules. Most of the citizens say they never care about the logo on the bottle. "Even the content of trace elements is basically not seen, let alone pH." Ms. Zhao of the public said that he usually bought mineral water at most, just to see if it was not in the warranty period. Mr. Xu, a member of the public, said that although he had read the news to understand the implementation of the new regulations, he did not care about the acidity and alkalinity of mineral water. Ms. Feng also said that the acid and alkaline properties of water had nothing to do with the human body, but they felt that the "alkaline water" advertised on the market became more and more popular.
it is known that the pH value of water is 7, it is the intermediate value, indicating that water is neutral liquid, and the pH value of acid and acid like sulfuric acid and hydrochloric acid is less than 7, it is acid liquid; the pH value of soda and caustic is more than 7, and it belongs to the alkali class. The pH of normal human blood is between 7.35 and 7.45, which is a weak alkaline constitution, but this part is only about 10%. The body fluid PH of the vast majority of people is below 7.35. The body parts are more vulnerable to disease under the acid constitution, and are in the subhealth state between health and disease for a long time, which is called "acid physique" in medicine.
