What You Need to Know
The acidic environment (pH ~2.5-3.5) denatures polyphenol oxidase enzymes while promoting hydrolysis of collagen into gelatin through acid swelling. Citric/malic/acetic acids chelate copper cofactors in tyrosinase.
Essential for pale stocks and aspics where visual clarity is prioritized, particularly in preparations like consommé blanc or galantines.
