Sea cucumbers from Weihai, Rongcheng and Changdao have the best nutritional value and are usually 4-rowed. Sea cucumbers are gelatinous, the nutrients are surrounded in the gelatinous, and the nutrients can only be absorbed by the human body by breaking the cell wall through physical technology. The nutrients of sea cucumber do not dissolve in water, so it is not afraid of the loss of nutrients of sea cucumber. I recommend Weihai local lightly dried sea cucumber as the best. Adding salt will destroy the active substances in the sea cucumber, and the nutrients will be lost. The method of identifying dried sea cucumber is superficially simple: one break, two look, three smell, break is to determine the degree of dryness and wetness of the sea cucumber, if the sea cucumber is very hard to break, not to be able to prick the hand proves that it doesn't contain water. If the hand can be broken, it is proved that this is six or seven percent of the dried senator, the price will be cheaper naturally * here indicate that ten percent of dried sea cucumbers as long as they are put in a ziplock bag. If you buy dried sea cucumber, the seller will remind you to put it in the refrigerator to save it, then you must carefully consider whether it is watered down or not, only the watered down sea cucumber is easy to dampen before it is preserved that way. Look and smell, some sea cucumbers may add some medicinal water and other things in order to make the color and shape look good when they are being processed, so you should take a look at the color and smell if there is any peculiar smell, the normal dried sea cucumber should be brown and light sea water smell. Normal lightly dried sea cucumber should be brown in color with light seawater smell. The most important point is to look at the size of the sea cucumber issued, issued to the senate large, thick skin to prove that the quality of sea cucumber is good Unadulterated light dry sea cucumber should be well hair can have the original length of two times to two and a half times, here it is recommended that you buy senate should be the first to buy less, go back to the hair of the good and then buy. Price, take Weihai sea cucumber, light dry sea cucumber should not be less than two thousand Here can be simply calculated: processing a catty of light dry sea cucumber need to use wild sea cucumber 25 pounds, the market price in accordance with the price of the spring of last year, eighty yuan a catty (of course, sea cucumber prices are unstable, this year at this time has not been out of the senator, the last year in the fall and winter of the sea cucumber are ninety) so the cost of the cost of calculating up to 80 Multiplied by twenty-five, that is two thousand, which is not counting the cost of fees and labor costs a catty minimum of about 2200 Of course, no one will not not make money on so sold to you. If you see a sea cucumber sold for less than 2,000 yuan, it is possible that it is not dry, or it may not be a local Weihai sea cucumber, like the Soviet Union cucumber is quite similar to our local sea cucumbers, the way to differentiate between them is to buy fewer of them, and go back to the hair and look at the Soviet Union cucumbers are sent out with a very thin skin Nowadays science and technology are more advanced, you can't buy sea cucumbers by looking at the number of heads you can weigh in one catty. If you look at the same price of a freshly dried sea cucumber that is almost as big as you do, you should choose the one that has a large number of heads. The same price of light dried sea cucumber, if it looks almost the same size, choose the one with more heads, it may not exclude the one that has been added with edible glue This must smell its flavor, it is quite difficult to distinguish between the old way, it is best to compare the three~ Salt-dried sea cucumber is generally in the price of two hundred to two thousand dollars, the difference mainly lies in the processing of it with a couple of times of salt, the more the salt rolls, the cheaper it is to sell. (Here to remind you, salt dried sea cucumber looks a catty is much cheaper, but often you count the price of a sea cucumber it is generally more expensive than the light dry sea cucumber) the same size of dry sea cucumber in the roll of salt after the individual become very large, weighing the number of heads on the less, and the price is much cheaper This is very easy to give the consumer a kind of misguided, will think that and big and cheap. However, the effect of sending out is very different, because the salt-dried sea cucumber has already risen in the salt water, so it is not much bigger and the skin is also thin. The more salt is added, the bigger the sea cucumber will be, and the lower the nutrient content will be. A salt-dried sea cucumber that costs several hundred dollars is usually the size of the original sea cucumber, so there is no nutrition in this kind of sea cucumber, and it may be added with food glue, lime, alkali and other chemicals, which will cause side effects to the human body if eaten. The price difference between lightly dried sea cucumber and salt-dried sea cucumber seems to be very big, but in fact, they are more or less the same if you want to give it to someone else, you have to decide according to your own conditions; if you want to eat it yourself, we suggest you don't buy salt-dried sea cucumber. The container of sea cucumber must not have oil, it is better to use pure water, and the tendon of sea cucumber must not be thrown away, don't just want the size of the sea cucumber, the nutritive value of the tendon of sea cucumber is quite high oh! This is just a little bit of my own experience, just for reference
