About

A complex Aspergillus ferment on garlic, rice bran, and rice vinegar. Traditional-style postbiotic; Aspergillus strain QC is the critical hinge.

This is a complex fermentation product produced by Aspergillus species (typically the safe, food-grade A. oryzae or A. sojae used in koji) on a multi-substrate of garlic bulb, rice bran, and rice vinegar. The result is a rich matrix of peptides, enzymes (proteases, amylases), organic acids, and garlic-derived sulfur compounds. The key supplier-safety concern is strain specification — some Aspergillus species (A. flavus, A. parasiticus) produce aflatoxins, which are highly hepatotoxic and carcinogenic. Food-grade koji fermentation uses non-toxigenic strains, and cosmetic-grade material should specify this and include mycotoxin QC. Typical use 0.5-5% in natural-positioning products.
