How to choose strawberries
1. Look at the shape. You can't buy strawberries that are too big or too watery; don't buy deformed strawberries that look strange. Some strawberries are bright in color, with abnormal bulges on the particles, and hollow in the middle after biting. This kind of abnormal berry is often caused by the abuse of hormones during the planting process, and long-term consumption of large quantities may damage human health. Pregnant women and children, in particular, should not eat malformed berries. The normal growing strawberries are heart-shaped.
2. Look at the color. When selecting, we should try our best to select the whole fruit that is bright red, uniform, bright and glossy. It is not suitable to choose the fruit that is not all red or half red and half green. The 'white sesame' on the surface of strawberry should be golden yellow. If you see that the 'sesame' is also red, it may be dyed. When buying strawberries, you can use your hand or paper to gently wipe the surface of strawberries. If you stick a lot of red on your hand or paper, you should be careful. Moreover, when the strawberry sprayed with pigment is washed with water, the water will turn light red.
3. Look at the surface. Strawberries with bright green leaves, fine fluff, bright surface and no damage and decay are good strawberries. Those with white or gray spots on the surface may be sick strawberries.
