Information Expanded:

Raisins (English name: raisin) are the fruits of grapes that have been dried in the sun or in the shade. Grapes are also known as grass dragon pearl. Mainly produced in Xinjiang, Gansu, Shaanxi, Hebei, Shandong and other places. Harvested in late summer and early fall, used fresh or dried for spare.

The raisin meat is soft and sweet, rich in nutrients.

The main components of the quick-drying agent is commonly used alkali and emulsifiers, used to destroy the wax and cuticle of the skin of grapes, so that the water inside the grapes easier to evaporate, which is the secret of the grapes "quick-drying". Alkalis and emulsifiers are very common and safe chemicals, so don't worry.

Whether or not you can rub out the white edges depends on how dry the raisins are and how hard you rub them. If they are dry and rubbed hard enough, they will produce white edges. This method has some reason, because the treated raisins skin is not so strong, lower toughness. So this method can not completely identify, but can be used as a reference.
