I know that freshly stewed donkey-hide gelatin is a dried product of swim bladder, which is very nutritious. Fresh stewed gelatin is an instant gelatin optimized on the basis of dry gelatin, which does not need to be stewed by itself. However, some common glue products on the market are made from the leftovers of swim bladder, which are not the best despite their nutritional value. Moreover, in order to increase the shelf life of ordinary fresh stew glue, there will be some additives to some extent, and brand glue that is truly additive-free is rare. As far as I know, glue interest is one of them.

Gum-flavored gum, stewed on the day of ordering. Because it is not added, the shelf life is only fifteen days, and it is SF Express, and the goods can be received soon, avoiding deterioration due to external factors such as environment and temperature. This kind of chewing gum is relatively fresh. The chewing gum used in chewing gum interest is all five-year-old deep-sea red-billed flounder chewing gum, which is a relatively large piece of chewing gum, and its nutritional value is incomparable to that of chewing gum made from ordinary leftovers. In fact, the way to distinguish between good and bad glue is also very simple, which can be basically distinguished from the size of the block. If the rubber product is small, it will certainly not be much better.
