Look at the product labeling drink natural mineral water separately

"It turns out that this is called real natural drinking mineral water

In the business acceptance hall of the Wuhan Food Inspection Institute, the staff checked the information

In the pre-treatment room, the inspector will pre-treat the food to be inspected: after chopping and homogenizing, it is placed in different areas to be inspected according to the different test items

In order to let the children experience the process of food testing up close, Xu Qing and Zhou Xiaoting, inspectors of the Chemical Testing Center, showed the children two commonly used detection instruments - "liquid chromatography- mass spectrometry" and "gas chromatography", which can be used to detect pesticide residues, food additives, veterinary drug residues and other items

At the end of the tour, the children came to the interactive experimental area, and the inspectors taught the children to conduct a quick test experiment on vegetable pesticide residues

"After homogenizing the vegetables, add 60 ml of extract, shake for 30 seconds and then stand for 1 minute, drop the sample extract on the test strip, just by comparing the shade of color of the color line, you can determine whether the pesticide residue exceeds the standard

Towards the end of the event, the children were attracted by a variety of bottled waters on the experimental table

"You can pay attention to the label on the bottled water, not only the back of the natural mineral water, but also on the product standard number marked GB8537, is to drink natural mineral water, and the rest may be drinking pure water, other types of drinking water and so on

Zhou Weijing introduced that compared with pure water, mineral water contains trace elements that are beneficial to the human body, but whether it is pure water, mineral water and other types of drinking water, the impact of long-term drinking on physical health is basically the same, because the purpose of drinking water is only to replenish water, not to supplement nutrition
