One, the harm of fake shark fins

1, fake shark fins in the easy to eat industrial gelatin and sodium alginate

"Gelatin and sodium alginate, which are used in industrial production, may themselves have been contaminated with heavy metals." There are edible and industrial versions of gelatin and sodium alginate.

"Food-grade gelatin and sodium alginate, which are sometimes used as food additives, have little effect on the human body if the dosage is controlled within safety standards." Chen said gelatin and sodium alginate, used as additives, can increase the product's consistency and "make synthetic shark fins more like real shark fins."
