Sun-curing method: First, direct exposure of selenium in the sun to make brown raisins; The second is drying in the shady room; The third is the rapid drying method adopted in recent years, the grapes are first treated by dehydrating agent, and then dried in the shady room or dried in the dryer, which greatly reduces the drying time. The fruit must be ripe, the water content of raisins is only 15-25%, and the fructose content is up to 60%. So it's very sweet. Raisins can therefore be stored for a long time, and the fructose in raisins may crystallize over time, but this does not affect their consumption.
The raisins made from seedless grapes in Turpan, Xinjiang, China, are the most famous. The climate in Turpan is hot and dry. There are many holes in the walls of the brick dry house, and there are sticks in the middle.
