1, look at the color
Good quality sea cucumbers are brown or black in color, and some are grayish black with dull surface. If you see sea cucumber with white color or high brightness, preservatives may be added, so consumers should choose carefully.
2. look dry.
Dry sea cucumber must do it. Dry sea cucumber is not conducive to preservation and easy to deteriorate. Good sea cucumbers should be 100% dry, while some poor quality sea cucumbers are not dry enough, and they feel heavy or even wet.
Step 3 look at sea cucumber thorns
Only those with strong and straight thorns will grow thick, so that the nutritional accumulation of sea cucumbers will be more abundant. If the thorn is very thin and weak, it means that the quality of sea cucumber is not very good.
4. Look at the shape of sea cucumber
The shape should be complete, and the shape of 100% dry sea cucumber will be a little dry. Good sea cucumbers are thick in the middle and thin at both ends, and some cultured sea cucumbers are relatively slender as a whole. When you see some sea cucumbers with abnormal shapes, they may be over-treated or added with other substances.
5. Look at the feet of sea cucumbers
The feet of wild sea cucumbers are clearly visible, because sea cucumbers are wild and need to feed themselves, and the sea area where they live is fast and needs to crawl constantly, so the feet grow thicker and can be clearly seen after processing. If the feet are not obvious, it may indicate that the sea cucumber is cultured and the quality is not good.
