The reason why gelatin is well known to the general public is because of "poison capsules" and "old yogurt". For consumers who are highly allergic to chemical terms, even "smell the glue discoloration", they wish that this kind of thing does not exist in the world.
In fact, gelatin is not a new thing, but it has always appeared in public in other vests. Many vests are still very "tall" and are sought after by health enthusiasts and fashion people.
Here are a few of its vests:
1. Buddha-figures - gelatin
Gelatin is derived from animals' fur, bones and gastrointestinal tracts. Heat these raw materials under acidic or alkaline conditions for a long time, and the collagen in them becomes smaller fragments and dissolves into water. After the residue is removed, it is dried and the gelatin is obtained.
2, mysterious vest - ejiao
Ejiao is perhaps the most "noble" vest. Ejiao differs from ordinary gelatin only in that modern ejiao uses donkey skins as raw materials, and the production method requires a "traditional process" that requires secrecy. Many people, including ejiao manufacturers, have tried to use scientific methods to confirm its legendary "miracle effect", but so far there is only some specious evidence, which has been considered by the scientific community to be "unable to prove the conclusion", but can be used to make fans who originally believe in its miracle effect happy. CCTV has reported that a large number of "fake ejiao" have flowed into the market, but I have never heard of the complaint that "ejiao is ineffective" - this probably shows that as long as you wear the vest of "ejiao", no matter whether it is "true" or "fake", it is the same.
3, high-tech vest - hydrolyzed collagen, collagen polypeptide, small molecule collagen
These are vests that are precisely aimed at fashionable women. Gelatin or ejiao is a slightly hydrolyzed collagen, while these are collagen with a high degree of hydrolysis. In fact, as long as the protein is eaten into the stomach, it must be hydrolyzed, and these "collagen after high-tech treatment" are only carried out in the body for the job of the gastrointestinal tract.
4, petty bourgeois vest - gilliptin powder
Gelatin in English is gelatin, and "gileatin" is a petty bourgeois translation that is popular among culinary enthusiasts. Melt it in hot water and when it cools down, it becomes a solid glue, and many jelly are made in this way. In addition, the thickening and gelatinization required for many foods are also achieved by gelatin.
5, notorious vest - industrial gelatin
Gelatin is a problem mainly because of the presence of industrial gelatin. In addition to being used in food, gelatin is also widely used in industry and medicine. Just like other industrial products, industrial gelatin does not control raw materials and production processes as strictly as food or medicine. Leather processing will be treated with some toxic reagents, and the scraps may also have some toxic substances. The gelatin produced by these scraps is not a problem for industry, but it cannot be used in food and medicine.
