1, the sea cucumber is short and thick, and the slender sea cucumber that looks attractive is not necessarily a good sea cucumber. In addition, you can choose ready-to-eat sea cucumbers by looking at their spines. Usually, the spines of high-quality ready-to-eat sea cucumbers are relatively tall and straight, and the epidermis is also very complete, giving people a feeling of being like a good sea cucumber at first sight. And some inferior products, such as instant sea cucumber foamed by caustic soda, will have "skin explosion" on the surface and ginseng will also break.

2. High-quality sea cucumbers live in clean sea, so the sea cucumbers themselves will have a fresh taste, which can be smelled when selecting ready-to-eat sea cucumbers. However, if the ready-to-eat sea cucumber smells slightly fishy, or has a strong medicinal taste, it means that the sea cucumber has added formaldehyde, preservatives and other pharmaceutical ingredients in the foaming process, which is an inferior sea cucumber.

3. When selecting ready-to-eat sea cucumbers, you can also feel the elasticity of sea cucumbers by hand. High-quality sea cucumber meat wall is relatively solid and the meat quality is better, so it feels more elastic. However, the inferior sea cucumber has relatively poor elasticity because some chemical components may be added in the foaming process, and the meat wall is fragile and the meat quality is damaged. In addition, you can also teach Dalian a trick. In the process of selecting ready-to-eat sea cucumber, the mouth of sea cucumber can be squeezed by hand. If it is inferior sea cucumber, the taste elasticity will be poor, and even it will be broken because of extrusion, but high-quality sea cucumber will not.
