Imitate dried soft-shelled turtle as dried abalone. Due to the high price of dried abalone in the market, some unscrupulous traders pretend to be "dried abalone" with worthless "dried abalone and turtle" to make huge profits from it. Therefore, you must be careful when buying dried abalone, so as not to be fooled; Like other shellfish, abalone has a hard shell, but the shell of abalone shell is very small, with a big mouth and a small hole on the edge (commonly known as "nine-hole snail"). Its feet are well developed and the soles of its feet are flat. The dried abalone sold in the market has been shelled, slightly boat-shaped, and one side is very smooth, that is, the sole of abalone. The "stone turtle" also has developed feet, the soles of which are flat, and can be used to pretend to be abalone with a little processing. But as long as you identify it carefully, you will find that the "stone turtle" will shrink and bend after drying, and the edge of its feet is very rough. The biggest difference between "fake abalone" and "real abalone" is that the former has a shell plate in the center of its back. Although it will peel off when it is processed and dried, it will always leave obvious marks. Therefore, there is no doubt that any "abalone" with obvious deep imprint on its back is a fake abalone.
