In fact, if you spend some time in the sea cucumber circle, you will soon understand the knowledge and avoid being deceived.
I combine my common sense mixed in the sea cucumber circle for many years, and tell you about the pits that may be encountered, and you will become an expert in an instant.
One is: Is it the sea cucumber in Dalian?
This is a very gullible question. Even in local shopping malls in Dalian, it is possible to buy sea cucumbers that are not produced in Dalian. Does it matter whether the sea cucumber is produced in Dalian?
According to the research of sea cucumber experts, the nutrient difference of sea cucumber is actually not that big. It doesn't seem to matter that much whether it is produced in Dalian or not. However, people's feelings about agricultural products are like this. A look at its nutrition and a second look at its taste. In terms of taste, the taste of Dalian sea cucumber is still very good, which is unmatched by sea cucumbers in other regions. Just as we say that grapes in France and dates in Xinjiang are different in soil, light and temperature difference between day and night, in a word, different climates make agricultural products taste different.
Why is it different? Under different natural conditions, the accumulation of trace substances in agricultural products is different. For example, in Dalian, big bone chicken is a specialty of Zhuanghe, and it is difficult to raise that kind of chicken in other areas. Even if it is raised, the taste of the chicken is different. There is also a typical farm egg. From the composition analysis of protein, there is little difference between eggs, but why there is such a big difference in taste? It is probably the difference between trace elements, just a little difference, and it is very different in the mouth.
Because everyone knows that Dalian sea cucumber is good, and not many people eat sea cucumber every day, the taste of sea cucumber is different. Therefore, the overseas sea cucumbers on the streets of Dalian are sold under the banner of Dalian sea cucumber, and most people can't tell the difference.
The second is: Is it a ginseng in the sea or a ginseng in the circle?
Even if you buy sea cucumbers at the seaside, it is not necessarily true that the sea cucumbers you buy are from the sea. Watching the diver jump into the sea, he carried out a net bag of sea cucumbers, which may also be captive sea cucumbers placed on the seabed in advance. This statement has always been popular in Dalian, called Bath Ginseng. I have never seen it with my own eyes, nor have I interviewed the operators of Bath Ginseng. It is all hearsay. My analysis shows that there will be such sea cucumbers.
Where did these sea cucumbers come from? It is said that some of them are fished out of the circle and put into the sea. Remember the longitude and latitude, and there are compasses on board, which can accurately find the place to put the sea cucumber.
Does it make any difference whether it's underwater or not? This question is the same as the last one. From the perspective of nutritional research of sea cucumber, there seems to be no difference. There is not much difference between the nutrients of sea cucumbers, but people still like to eat sea cucumbers that grow on the bottom of the sea. Why? The culture time of sea cucumber in the circle is short, it matures quickly, the trace elements are not accumulated enough, and the taste is very different. This is the same as the cage chicken and farm chicken mentioned in the previous example.
In fact, the biggest difference between the two is not the nutrition that the sea cucumber itself should have, but the drug residue that the sea cucumber should not have. Captive sea cucumbers have the opportunity and possibility to feed bait and medicine. For this question, although many people who do sea cucumber circles feel wronged, it is really difficult to say clearly. After all, there are reasons to put medicine and bait in captivity. And the bottom of the sea can be clearly skimmed, saying that their sea cucumbers are not fed with bait and medicine, and they can't afford to throw them into the sea, which is unnecessary.
If the sea cucumber on the seabed is found to have drug residues, there are two possibilities. One is that the sea cucumber seedlings are too big when they are put into the seabed, and they are kept in the cement pool on land for too long, and they eat too much drugs and bait, but they grow on the seabed for a short time and are not metabolized.
There are two kinds of sea cucumbers at the bottom of the sea, one is that wild sea cucumber seedlings grow up, and the other is that sea cucumber seedlings are put on the bottom of the sea. The former seems safer.
The third is: can you tell whether it is a sea cucumber for several years?
Many people will ask how old this sea cucumber is. Actually, this is a false proposition. Sea cucumbers can't be seen for several years physically, unlike trees with annual rings. Those experts who specialize in university can tell the male and female of sea cucumber, but they can never tell the age of sea cucumber.
This question is also guided by people who sell sea cucumbers. People who sell sea cucumbers say that their sea cucumbers are four years old, five years old, or even eight or nine years old. They are all nonsense and have no basis. It's just that some seaside people judge by the size of the sea cucumber, and how many years it has been at the bottom of the sea before it can grow so big.
In fact, the size of sea cucumbers is the same as that of people. A person can't judge his age according to his size, and so can sea cucumbers.
The fourth is: Is it expensive or cheap?
The most incomprehensible thing about buying sea cucumbers is the price. There are all kinds of money. Take dry sea cucumber as an example, it ranges from 2000 yuan to 12000 yuan, and salted sea cucumbers are even more exotic, ranging from 200 yuan to 2000 yuan.
When you buy sea cucumbers, it's basically meaningless to ask how much a catty is. No matter how much it costs, there may be only five or six salted sea cucumbers in 200 yuan, and half of them are the weight of salt. What do knowledgeable Dalian people see? Look at sea cucumbers of the same size and quality. How much is one? Of course, few people talk about selling sea cucumbers by roots. Dalian people call them heads. From the perspective of heads, how much is a sea cucumber?
At the seaside, people buy sea cucumbers to see how much they weigh, and then see how much a sea cucumber costs. This is comparable. For those boiled, salted and dried sea cucumbers, salt and water are added, and some people even add sugar and plant ash. It is meaningless to say how much a catty is.
For example, some sea cucumbers are salted for more than 1000 yuan per catty, but there are 30 sea cucumbers in them, with an average of only more than 30 yuan per head; Some have a kilo of 400 yuan, only 10. Which do you think is cheaper?
Why is it that there are twenty or thirty sea cucumbers in the same catty, and some are only 10? This is related to the temperature and salt content during the processing of sea cucumbers. When the processing time is long, most of the water in the sea cucumbers is squeezed out, and the sea cucumbers become dry, and the salt is not added much, so naturally it is not so weighed. Some of them are processed with low heat, no water is squeezed out, and too much salt is added. Naturally, they are weighed, and 10 sea cucumber will weigh a catty.
You can buy sea cucumbers in Dalian, go to specialty stores, farmers' markets and morning markets, but the risks of each channel are different, and some channels have higher integrity, such as specialty stores. However, what people believe more is the seaside of enterprises that know their roots well, watching divers go down to fish and weigh them ashore.
Although this does not guarantee that the sea cucumber you bought really comes from this seabed, there are few things like bathing, like legend, and for those big sea cucumber enterprises, the brand is more important, so it is not necessary to do that.
I suggest that you buy sea cucumbers, learn more about them, and go to a branded store or a reputable enterprise to buy them. For example: Chaoyang ginseng.
Here are some tips for buying sea cucumbers, which I summarized after interviewing professionals.
Pick sea cucumbers, see them, smell them and touch them.
It is best to look at the product standards.
The first is to look. See if the shape of the sea cucumber is full and the thorns are firm. If it is a southern sea cucumber, the thorns are generally ugly, like a bump and not sharp. However, it is not a good sea cucumber if it is too sharp. Compared with the sea cucumber sown under the sea, the thorns of the captive sea cucumber will be thinner and sharper. Look at whether the appearance is thick or not. After some overseas sea cucumbers are processed into dry sea cucumber, they are like honeycomb briquettes, and they are full of pores.
The second is to smell. That's a clever move. The taste of the sea water in the south or the water in the blisters is very different from that in Dalian. The sea water in Dalian has a fresh taste, but the sea cucumbers in captivity often don't smell so good, and the sea cucumbers in the south taste even worse. Different water quality, different taste.
The third is to touch. This is mainly manifested in the instant sea cucumber and salted sea cucumber. Feel to see if it is strong and elastic. Hold one third of the instant sea cucumber to see if it is still firm and resilient. Drop live sea cucumber or salted sea cucumber on the ground to see if it will bounce. A sea cucumber that can dance is a good sea cucumber.
According to industry insiders, the best way to buy Dalian sea cucumber is to look at product standards. There are two product standards for sea cucumber, one is the product quality standard of national geographical indications, and the other is the quality standard of the Ministry of Agriculture. These two standards have clear requirements for the salinity, water content, protein content and water-soluble polysaccharide content of sea cucumber. Consumers need to recognize the standard and purchase the sea cucumber. The sea cucumber of Chaoyang Ginseng brand meets the national standards.
The common problem in the market is that the water content and salt content exceed the standard. Some enterprises try their best to add salt to sea cucumbers, but edible salt is not allowed in raw materials in dry sea cucumber. The salt in sea cucumbers comes from sea cucumbers, but many sea cucumbers in the market add salt.
It is worth mentioning that many people don't know the concept of "inflation rate" when buying sea cucumbers, which is a key factor. If the inflation rate of sea cucumbers is not high, it means that the sea cucumbers they buy have shrunk, which is equivalent to the "housing rate". The actual price of sea cucumbers is divided by the inflation rate. "The rate of increase must be actually increased to know that the rate of increase in business promotion is actually unfounded."
