How to Identify Sulfur Raisins

1 Color

It is very important to choose the color of raisins. The color should not be too bright. The brighter it is, the more problems there are. The color of raisins depends on the color of the grapes themselves. For example, there are no yellow grapes, so there can be no golden raisins! The beautiful golden raisins sold on Taobao, such as "Golden Queen" and "Tree Yellow", are most likely smoked with sulfur, so it is recommended to choose with caution.

Purely natural things, because they grow naturally, it is impossible for them to have the same color. Color difference is normal. If a bag of raisins is all bright green, they must have been artificially processed and it is recommended not to buy them. There are more than 600 varieties of grapes, more than 300 of which are edible, but based on their general color, there are four main types: green, red, purple and black. Of course, there are many different shades of each color, and the taste is naturally different. Here I will briefly introduce the color varieties of raisins.

Green raisins: the most common variety, with a sweet and sour taste, thin skin and thick flesh, a refreshing taste, thick flesh, and no residue. Common ones include Arctic King, Green Xiangfei, Green Mare's Milk, Hami King, Seedless White, etc. Each one has a unique taste and is worth tasting.

Red raisins: The reason they are red is that they contain anthocyanins, which have a blood-replenishing effect. Therefore, there is a saying among the people: red grapes are yang and are good for men, while green grapes are yin and are suitable for women. Common red raisin varieties are arranged according to grain size: Red Xiangfei, Red Mare's Milk, Yacon, and Hotan Red.

Black currant raisins: purple and black raisins. The advantage of this type of raisins is not the taste, but also the fact that they contain a lot of tannins and anthocyanins. Tannins are good for the heart and anthocyanins are anti-aging. The biggest advantage of black currant is its extremely high content of anthocyanins and VC. It is known as the king of vitamins and has anti-aging and whitening effects.

2 Dry Tide

There should be certain spaces between the raisin particles, and those that are sticky should not be purchased. Grab a handful of raisins with your hand, squeeze it tightly and then put it down. If the raisins can quickly spread out, it is worth buying. Touch the raisins with your hand. If the surface is dry, without moisture or stickiness, then they are of good quality. Do not buy raisins with sugar oil on the surface. It is better to buy raisins that are crystal clear and bright in color after wiping off the frost on the surface. Use your fingers to pinch the raisin grains. If the raisin grains crack easily, these are low-quality raisins that are small and shriveled and should not be purchased.
