误区：发制海参时一定要去掉海参内壁上的筋，否则他就会像牛皮筋一样影响海参的涨发。
部分人眼中的海参筋，其实是海参的内腺管。不知道大家注意到没有，海参有几排刺，就有几条内腺管。内腺管富含海参酸性黏多糖、海参素、核酸及18种氨基酸等活性物质，还含有硒、锌、铜、锰等30多种微量元素，扔掉实在是太可惜了。经过反复试验，我们发现，内腺管对海参的发制不会有任何影响。
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.

因此，建议大家不要盲目去掉营养价值极高的内腺管。另外，很多厨师在处理海参时，往往会用手指刮掉附着内腺管的内腔膜，这种做法也是非常错误的。
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.
