1. Cleaning blueberries with diluted starch water is the most correct cleaning method, because starch water contains a certain amount of starch, which has strong adsorption performance and can adsorb dirt on the surface of blueberries. After diluting the starch, add the blueberries, stir them gently by hand, take them out after five or six minutes, and then rinse them with clear water.

2. Rinse repeatedly with clear water, but you can't rub hard with your hands during the rinsing process, otherwise it will destroy its epidermis and make the nutrients in blueberries lose. If you are worried about pesticide residues on the surface of blueberries, you can soak them in light salt water for half an hour and then rinse them with clear water.

Blueberry shopping guide

1, look at the appearance

You must look at the appearance when you buy blueberries. If the tops of blueberries are bare, you should wipe their skins with paper. If there is color on the paper, this blueberry is fake. Dyed with jujube or cherry is likely to be fake, so don't buy it.

2. Look at the frost

Good quality, ripe blueberries are all blue-purple on the surface, and there is light frost on the surface. If the blueberry is red, it means that the blueberry is not ripe yet. In addition, if the frost on the surface of blueberry is not obvious or there is no frost, it means that this blueberry has been preserved for a long time and is not fresh at all, so it is not suitable for buying and eating.
