Tips for purchasing abalone: ??As the most delicate member of marine life, abalone is very picky about its living environment. Not only are abalone difficult to find in mixed water or sediment-bottomed seawater, but even slightly polluted seawater can cause abalone to be destroyed, making artificial breeding of abalone very difficult. Therefore, wild abalone is a real green food. The collection and fishing of abalone is very professional. Every year when the water temperature rises, abalone will move to shallow seas to breed, which is commonly known as "abalone going to bed". At this time, the abalone has rich meat, well-developed gonads and is the fattest. "The fat abalone flows in July" is a metaphor for this time. As a high-end cooking ingredient, abalone is expensive. When purchasing abalone, you must master certain skills and common sense. The most direct way to select abalone is to look at the appearance: first, the shape is complete. First, eliminate those with gaps and cracks in appearance and select abalone that is intact and of good quality. Second, the meat is fat. Generally, thick meat is better than flat meat, and meat with a wide base is better than thin body. Third, the shape is consistent. All kinds of good-quality abalone usually have similar shapes. If you have strange shapes, you should pick them out when purchasing. Fourth, the color is normal. The color of fresh abalone is related to the time of death. The darker the color, the longer the death time and the worse the freshness, making it unsuitable for purchase. However, some dried abalone will have a few spots, indicating that the abalone is not completely dried and is dry on the outside and moist on the inside. Please pay attention when purchasing. When the vitality is strong, the "face color" of fresh abalone appears dark and shiny, and the muscles are soft and elastic. At the same time, fresh abalone seen in fish ponds or aquariums clings to tiles or glass like suckers. It really takes some effort to peel it off! It can be concluded that fresh abalone that can be attached to objects must be alive. On the contrary, if fresh abalone is stored for a long time, it lacks food and even loses vitality; or if the water temperature and salinity are not suitable, it will feel uncomfortable and gradually die. Therefore, when the "surface-attached color" gradually fades, the attractiveness of the abalone body will begin to weaken. At this time, in addition to "discoloration", the fresh abalone's muscles also contract and show signs of "hard mouth", which is a prelude to death. However, the death time is not too long, and even if the meat is a little worse, it is still edible. If the time of death is too long, the meat will inevitably change and the color will become lighter and lighter. Just like the "blank slate" in mahjong, muscles will turn from hard to fat, rot and even smell.
