Description of Black Garlic Extract:
Black Garlic Extract: A Fermented Food.Black garlic extract is produced by fermenting fresh, skin-on raw garlic in a fermentation tank for 90-120 days. During this two-to-three-month process, special biological methods ferment the raw material. This fermentation breaks down proteins into amino acids and carbohydrates. Notably, it also converts allicin into an odorless, low-irritation, and less-reducing form, which gives the garlic its characteristic black color. The active ingredients of black garlic extract are: black garlic polyphenols, SAC, etc. Allicin in black garlic extract is an effective bactericidal active ingredient.
