Some people like to buy raw ingredients in traditional markets. For example, sausages. Many people think that the "live jump" sausages bought in the market must be fresher than the cold sausages in supermarkets, but is it really the case? Is it a live or cold sauce that is fresher? The Food and Drug Administration and the Farm have said that "the safest shrimp is directly preserved in low-temperature cold sauce."
The latest freshness of "live jump"?甲甲 pointed out that the fresh squid looks clear from the outer shell, and it is light from the eyes to the shell, as if it is emitted from the body. The dying sack will begin to turn white, which is the opaque white; if the whole sack is grayish white, it means that the stage of quitting has been long; the sack that has died longer will begin to turn red, just like the color of the boiled sack just after the sack is boiled.
{}The Food and Drug Administration pointed out that once the fish vegetatives are discharged from water, the enzymes in the body will begin to react, and the body will gradually change color and have a strange smell. In the process of catching the vegetative, especially the vegetative, it is easy to be crushed to death because it is "too swelled". Even if the vegetative is alive, the body may start to smell strange because it is damaged.
It is recommended that consumers should try not to buy lively and erectile squids in non-properties, because the injured squid cannot be seen from the appearance. Even if they are not injured, they will die due to inappropriate conditions when they leave the original squid. In order to make the bait active for a few days, sellers often add drugs to the water. If they add some irritating drugs, they can even make the bait look very lively. Therefore, you think that the squids bought in the market are not fresh, and it is very likely that they have added medicine.
The fresh beard is so picking1. Pay attention to whether the head of the beard is closely connected to the body of the beard, and whether the head of the beard has shiny slightness.
2. Is the body of the squid naturally curled? Is the body full of flesh?
3. Pay attention to whether the color has changed and there is a strange smell. It has no abnormality and no ammonia odor, which means that the basin is fresh.
In addition to the disputes about live and cold shrimps, there are actually quite a lot of myths about shrimps. The following Yuanqi Network compiled several common problems about shrimps in the "Aquaculture Testing Institute". I hope that everyone will no longer be "blind" when buying shrimps in the future!
Q: Is the head of the squid getting darker and not fresh? Can you still eat it?A:
Blacking head has nothing to do with freshness, but it is recommended to store fresh saps in cold conditions, while preventing too much temperature changes and eating them as quickly as possible in the short term.
(1) After the oxidation dies from water, polyphenol oxidation enzymes in the body catalyze the tyrosine healing to produce melanin, forming black spots on the oxidation surface, which are prone to appear at the tail and feet, called "black change". It is a natural phenomenon and can be eaten, and cannot be used with fresh and high-quality numbers.
(2) The black change of the sac is a normal phenomenon. It is not popular in Taiwan and is even misinterpreted as unrealistic. In order to view and sell appearances, unscrupulous businessmen added borax (boronic acid sac) commonly known as ice-saccharide to prevent the black change of the saccharide. Borax is a banned product for food processing. After human retrieval, it will hinder nutrient absorption, resulting in lightweight weight, which may cause vomiting, red spots, shock and other poisoning symptoms, and is fatal.
(3) To prevent the meat from becoming black, shattered, and pulp-fried, unscrupulous, whitening flakes (bleach) may also be used in the shop. It can be regarded as a formaldehyde derivative, which was originally an industrial chemical used in dyeing technology and has a strong anticorrosion effect. Hanging white chunks and borax is equivalent to a guarantee that it is not prone to deterioration and will not be blackened. Of course, it also guarantees that it seriously endangers physical health.
Q: Will boiled oranges with oranges with hot pot be chronically poisoned?A:
Ata (Astaxanthin, Asta), another name called astacin, is a pigment widely found in animals, plants, algae, and microorganisms. It is a type of carotene. The sap is fed with algae or feed, and can accumulate sap red in the body. In addition, the sap also has the ability to transform other sap red in the body. Because the red beans in the living beans are combined with protein, they appear blue-purple or green under light due to changes in their three-dimensional structure. When heated, the protein is destroyed and changed. After separation from red beans, the color becomes the original orange (yellow) red color, that is, the color of the boiled beans. The cell membrane of the beans is broken due to heated, and the cell fluid and red beans will flow out, so the orange-red floating objects will float in the beans.
Q: How to remove the ice so that the white sausage will not taste scattered?A:
The cold-fried white basin ice removal procedures include: refrigerated grinding, running hydrolysis grinding, salt water soaking grinding and microwave grinding. It is recommended that salt water soaking grinding and microwave grinding can maintain the sweetness of white basin; however, the taste and texture of white basin are not only related to the method of ice removal, but also related to the breeding environment, the state of the basin, the harvest time, the method of slurry treatment, the storage time, the number of refrigerated grinding refrigeration times, etc.
Q: Can I eat the squid? Which parts of the sap cannot be eaten?A:
用的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的的�
In addition, if there is an added drug for fresh fish, the fish will remain in the internal organs, and the seeds will remain in the head and kidney glands. Therefore, it is recommended to pick off the kidney lines before cooking the sap, and do not eat the sap when eating.
