In some people's eyes, sea cucumber tendon is actually the internal gland tube of sea cucumber. I don't know if you notice that there are several rows of thorns in sea cucumber, and there are several internal glandular ducts. The inner gland tube is rich in active substances such as acid mucopolysaccharide, sea cucumber element, nucleic acid and 18 kinds of amino acids, and also contains more than 30 kinds of trace elements such as selenium, zinc, copper and manganese. It's a pity to throw them away. After repeated experiments, we found that the internal gland tube had no effect on the hairline of sea cucumber.
Therefore, it is suggested that we should not blindly remove the internal glandular duct with high nutritional value. In addition, when many chefs deal with sea cucumber, they often use their fingers to scrape off the inner cavity membrane attached to the inner gland tube, which is also very wrong.
