Abalone purchase skills
The appearance is the first thing we notice when we choose abalone, because many abalones are relatively complete in appearance and slightly smooth in shape, and there will be no gaps or deformities. Of course, if we encounter such an incomplete appearance and not smooth enough in shape during the purchase process, there are still some dirt or cracks on the surface, such abalones must not be purchased.
If you really can't identify it, friends can directly take a photo of the abalone under the light. If the abalone looks particularly transparent and is that red under the light, it means that the abalone is relatively fresh, and its taste is very good, and its nutritional value is also high. This kind of abalone is what we should choose.
