🌟 Key Applications & Functions
1. Food Processing & Acidity Regulation
In the food industry, Calcium Oxide is used as an acidity regulator and processing aid. It is commonly employed in the production of sugar (to clarify the juice), in the processing of corn (nixtamalization), and as a firming agent in certain canned fruits and vegetables.
2. Nutritional Fortification
As a potent source of elemental calcium, it is used to fortify various food products, including dairy alternatives and infant formulas, supporting bone health and overall metabolic function.
3. Dough Conditioning
In large-scale bakery operations, it acts as a dough conditioner, improving the texture and stability of bread and other baked goods by regulating the pH levels during fermentation.
4. Pharmaceutical Excipient
Used as a stabilizer and pH adjuster in pharmaceutical formulations, ensuring the shelf-life and efficacy of medicinal products.
