Waxing is to keep the fruit fresh and look better. Therefore, the relevant laws and regulations in China allow artificial waxing of fruits, but edible wax must be used. It is very simple to remove this layer of edible wax, and this layer of artificial edible wax can be removed from the apple surface by washing it directly with hot water. However, due to cost considerations, it is not excluded that some vendors may use industrial wax, which is harmful to the human body. In addition to artificially waxing apples, apples themselves actually produce "wax"-fruit wax. The biggest difference from artificial waxing is that apple's own fruit wax can't be scraped off. It is suggested that when selecting waxed fruit, you can wipe the surface of the fruit with your hands or napkins. If you can wipe a layer of light red, it may be industrial wax. Edible wax can be removed by washing with warm water or rubbing with salt. But if the apple is coated with industrial wax, it is difficult to clean it. Suggest eating apples or peeling them.

In daily life, consumers should not pay too much attention to the glamorous appearance of fruits, eat more fruits in season and carefully choose fruits out of season.
