Food-Grade Calcium Hydroxide: A Versatile Ingredient in the Modern Food Industry
In the evolving landscape of food manufacturing and safety, ingredients that combine function, tradition, and regulatory compliance are increasingly sought after. One such substance is food-grade calcium hydroxide—a compound rooted in centuries-old culinary practices and now playing an important role in modern food processing.
What is Food-Grade Calcium Hydroxide?
Also known as slaked lime or hydrated lime, food-grade calcium hydroxide is a white, odorless, alkaline powder derived by hydrating calcium oxide (quicklime). The “food-grade” designation ensures the compound meets strict purity and safety standards as required by regulatory bodies such as the FDA, EFSA, and Codex Alimentarius.
