1. Measured over orange juice professional PH test strips (left) and paper (right) 2. Results have tested vinegar comes after 3. The test results had orange juice after "look farmer spring mineral water is a weak base, gave paper, would often buy drink can go home with a test strip has found what measure ye these strips are slightly alkaline? "the morning of October 14, the public Ms Cheng said. Reporters followed by acidic liquid donated 10 test strip of orange juice, vinegar, such results were tested alkaline. Followed by professional PH test paper, the results close to strong acid. Experts said that this detection method itself is a great error. Although businesses advertised "weak base" Hush head, it is virtually impossible to change the constitution to drink alone.

Dipstick test trials presented consequently "weak base"

"I was just having fun, testing mineral water is a weak base, on the way to measure the test lotions and masks, yellow-green paper have shown a weak base, but I from a search online, they obviously are acidic in." Ms Cheng said.

October 14 morning, the reporter with the public doubts Ada, respectively, in five stores, select a bottle of 550 ml each farmer spring mineral water tested.

To be more clear, General Hing mechanical reporter then got the vinegar, orange juice, this is more representative of the acidic liquid. Then store bought chemical instrument professional PH test strips, and gift paper while immersed in vinegar and orange juice for two seconds, then place 1 minute contrast, we found a professional PH test strips were tested red, pH value of 3, close to the strong acid ; the farmer spring mineral water comes pH paper, was yellow-green color weakness alkaline mineral water before the test strips and consistent color.

In this regard, the public Ada that "thought presented with mineral water PH test, the product will be more convincing. But now I'm a bit confused, in the end there is a water quality problem, or gift paper is a 'bargain' detection was not allowed? "

Manufacturers of water is no problem, you may have a problem dipstick

Reporter consulted a number of supermarket staff informed, with strips of mineral water, obviously you want to sell better. With the public's questions, the reporter subsequently linked to the relevant person in charge of the farmer spring Qingdao office. He said that this kind of problem they have encountered before. However, the production of bottled mineral water factory, sent over a non-paper, the bonus test strips, just a promotion. Paper itself is not expensive, and many people worry detected, are willing to buy. Therefore, the customer requested when ordering, they will be free to hang strips, two bottle gift. "Could strip out of the question, but the water is mass production, no problem."

In this phenomenon, the reporter also interviewed Chemistry and Chemical Engineering, Shandong University, a teacher. He believes that the business itself "pH test paper water" approach is open to question. "Container, the solution is not to determine the concentration of the test, the people bought no more than right, just visually coupled with the delivery of the course is not easy to save paper, which will lead to large errors." And then the reporter found that not only the farmer spring, reporters use PH test strips a professional. Other brands of mineral water, purified water, PH value is almost always about 7. The person in charge of Qingdao Hairun Water Group's presentation, "The current domestic and international research on human health and the pH of the water is less, and it has not clearly correlated with the pH of tap water healthy relationship.

Experts do not specifically drink alkaline water

How can we do a healthy drink? October 14 afternoon, the reporter consulted the Tsing Yi Fuyuan nutrition main Renhan Lei. She first passed to reporters and the public view, although businesses advertised "weak base water health", but actually eating alone in a one, it is difficult to become a healthy physique. "So the average person without special drink alkaline water. The human body has a natural mechanism for regulating acid-base balance, the average person only needs to eat a normal, normal water on it. On the contrary, if the public have long, excessive drinking weak base of water, but increased the burden on the body, destroy the body's acid-base balance to some extent. "
