Li Yunhui, a reporter from Jiangxi, China, reported: August and September is the season for concentrated listing of grapes. recently, in the moments of many citizens, there is a news that "white frost on grape skins is a pesticide." The reporter learned from the Jiangxi Provincial Food and Drug Administration that the "white frost" on grapes is not pesticides, but fruit powder, which is completely harmless to the human body.

"with so much 'white frost' on the grape skin, why can't you wash it clean? is it pesticide residue?" Recently, many people in Nanchang are worried about the "white frost" on the skin after buying grapes. With the maturity of social platforms, the saying that "white frost on grape skin is a pesticide" is also widely spread in the circle of friends of citizens.

The reporter learned from the Jiangxi Provincial Food and Drug Administration that this layer of white frost is actually fruit powder and is harmless to the human body. This kind of white cream can be found not only on grapes, but also on the skins of fruits such as sugar cane and plums.

The relevant staff said that as long as the "white frost" that is evenly distributed and does not cover the color of the grape skin itself, it can be considered as a sugar alcohol substance secreted by the grape itself, professionally known as fruit powder, which is completely harmless to the human body. Fruit powder may be rubbed off during long-term transportation and storage, and the fact that grapes are covered with fruit powder can prove that grapes are more fresh. In addition, the fruit powder on the grape has a protective effect on the grape, which can effectively reduce water evaporation and the infection of pathogenic bacteria. Therefore, the fruit powder on the grape is not only not the evidence of pesticide residues, but also a manifestation of the rational use of pesticides.

The staff suggested that after buying the grapes, apart from soaking them in salt water, they could also put some flour in the water and wash off the frost in a few minutes. Flour has a certain adsorption effect, which plays a certain role in removing dirt and pesticides on the surface of grapes.
