1. Choose from the color: high-quality squid is transparent red with delicate body, transparent light yellow with thin body. If it is old squid, the color will be slightly purple and the body will be larger. If it is old squid, it is dark, does not look fresh, has a thick layer of frost, and is not transparent. In fact, such squid is not good for the human body after being processed. If people accidentally eat it, it will be harmful to the human body. A feeling of discomfort will occur.

2. Press the fish with your fingers. If the squid meat feels firm, elastic and soft to the touch, it is fresh squid. If the squid is not elastic to the touch and feels uncomfortable, please do not choose to buy it, because the squid is definitely not fresh and has been stored for a long time.

3. No damage, the whole body is intact, the meat is hard and thick, and its hardness and softness must also be judged. High-quality dried fish is soft, smooth to the touch, not hard, and the meat is thick. If the squid does not feel soft and dry, it is the result of long-term storage, and it is best not to eat it. If the squid has no flavor and is damaged, don't buy it. It will become like this after it has been left for a long time.
