3.Application scope and Usage
Butyl lactate (food-grade) is used as a flavoring agent, solvent, and carrier in food applications. It is commonly found in bakery products, confectionery, beverages, dairy desserts, and processed fruits, providing a mild, buttery, and creamy aroma.
4.Package and Storage
Butyl lactate (food-grade) should be stored in tightly sealed, corrosion-resistant containers(such as stainless steel, aluminum, or food-grade plastic drums) to prevent moisture absorption and oxidation. It must be kept in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and strong oxidizers. The recommended storage temperature is below 30°C (86°F) to maintain stability. Proper handling avoids contamination and ensures product quality during shelf life (typically 12–24 months under ideal conditions).
