Product Introduction
Calcium lactate is an odorless or nearly odorless salt, with a slightly bitter taste. It is created by the neutralization of lactic acid with calcium carbonate or calcium hydroxide.[1] This compound is soluble in water, which makes it useful in various applications, particularly in the food and beverage industry, due to its bioavailability as a calcium source.[2] It is also used in medical applications.
Production Process
The production of calcium lactate generally involves several steps. First, lactic acid is produced through fermentation of a carbohydrate source, such as corn or beet sugar. Then, this lactic acid is reacted with a calcium source, like calcium carbonate or calcium hydroxide, in a controlled chemical reaction to form calcium lactate.[3] The resulting solution is then purified, concentrated, and crystallized. The crystals are dried and milled to achieve the desired particle size, ensuring that the final product meets quality standards for its intended use.[4]
Product Functions and Effects
Calcium lactate functions primarily as a calcium supplement. It is readily absorbed by the body, supporting bone health, nerve function, and muscle contraction.[5] In the food industry, it acts as a firming agent, particularly in canned fruits and vegetables, maintaining their texture and preventing softening.[6] Calcium lactate also serves as a leavening agent in baking powders and improves the texture of baked goods and can control acidity in various food products.[7]
Product Application Scenarios
In the food and beverage industry, calcium lactate is utilized in a variety of products. It is added to fruit preparations and jams to improve texture and extend shelf life. In dairy products, such as cheese and yogurt, it enhances firmness and calcium content.[8] It's also used in baking as a component of leavening systems, contributing to the rise and structure of baked goods. Beyond food, the pharmaceutical industry employs calcium lactate in calcium supplements to address dietary deficiencies and support bone health.[9]
Packaging and Storage
Calcium lactate is typically packaged in multi-layer paper bags with polyethylene liners or in sealed containers to protect it from moisture and contamination. The product should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances. Proper storage conditions help maintain its stability and prevent degradation, ensuring that it retains its quality and effectiveness throughout its shelf life.[10]
