Overview
Sodium malate is a sodium salt of malic acid, commonly used in the food industry as an acidity regulator and flavor enhancer. It is often derived from recycled sources, making it an environmentally friendly option for manufacturers. The compound is widely recognized for its ability to improve taste profiles in beverages, confectionery, and processed foods. In addition to its culinary uses, sodium malate finds applications in pharmaceuticals and cosmetics, where it acts as a buffering agent and moisturizer. Its mild acidity and solubility make it a versatile ingredient in various formulations.
Physical and Chemical Properties
Sodium malate appears as a white crystalline powder with high solubility in water. Its molecular formula is C4H4Na2O5, and it has a molecular weight of 178.05 g/mol. The compound is hygroscopic, meaning it can absorb moisture from the air, which necessitates proper storage conditions. While specific data on melting and boiling points are not widely documented, sodium malate is known to be stable under typical processing temperatures. Its acidity-regulating properties make it effective in maintaining pH levels in food and beverage products.
Main Applications
The primary use of sodium malate is in the food industry, where it serves as an acidity regulator and flavor enhancer. It is commonly found in soft drinks, candies, and baked goods to balance tartness and improve taste. Its ability to mask bitterness makes it a popular choice in low-calorie and sugar-free products. Beyond food, sodium malate is used in pharmaceuticals as an excipient to stabilize formulations. In cosmetics, it acts as a humectant, helping to retain moisture in skin care products. Its versatility and safety profile contribute to its widespread adoption across industries.
Safety and Storage
Sodium malate is generally recognized as safe (GRAS) by the FDA, but proper handling is essential to avoid irritation. Workers should use protective gear, such as gloves and masks, to prevent inhalation or skin contact. The compound should be stored in a cool, dry place, sealed tightly to prevent moisture absorption. In case of accidental exposure, rinse affected areas with plenty of water and seek medical advice if irritation persists. Manufacturers should ensure compliance with local regulations and provide safety data sheets (SDS) to users.
B2B Procurement Guide
When procuring sodium malate, B2B buyers should prioritize suppliers with certifications like ISO or FSSC 22000 to ensure quality and safety. Request a certificate of analysis (COA) to verify purity levels, which typically range from 98% to 99.5% for food-grade applications. Price varies based on quantity, purity, and supplier location, with bulk purchases often offering cost advantages. Buyers should also consider logistics, such as shipping conditions and lead times, to ensure timely delivery. Establishing long-term contracts with reliable suppliers can mitigate supply chain risks.
