As a solid-state fermented acidifying ingredient, this product perfectly resolves industry pain points associated with liquid lactic acid, such as leakage during transport, formulation incompatibility, and excessive moisture content. Produced via advanced biological fermentation and refining processes, the powder features a fine texture and balanced acidity, making it a versatile, multi-functional ingredient for the food, solid beverage, animal feed, and personal care industries. It offers multiple benefits-including flavor enhancement, acidification, antimicrobial preservation, and improved product texture-while meeting international export quality standards.
Produced from natural carbohydrates via biological fermentation and solidified through low-temperature spray drying, this food-grade lactic acid powder overcomes the limitations inherent in traditional liquid lactic acid. It boasts excellent flowability and resistance to moisture absorption and caking, while delivering a smooth, natural sweet-and-sour flavor profile. It is highly stable and compatible with a wide range of other ingredients, offering a one-stop solution for acidification, preservation, and texture improvement. Fully certified, it is an ideal choice for overseas manufacturers sourcing ingredients for export.
Key Product Advantages
Produced using deep-tank fermentation and dual-purification processes, the product meets strict lactic acid content standards, features uniform powder fineness without clumping, and maintains consistent acidity levels across batches. Comprehensive documentation is available, including COAs, SDSs, and heavy metal/microbial test reports; the product holds full compliance certifications for the EU, FDA, Halal, and Kosher markets.
Unlike the sharp, pungent acidity of inorganic acid powders, this fermented lactic acid offers a mild, natural taste profile. It leaves no bitter aftertaste and does not mask the inherent aroma of ingredients, making it ideal for pH adjustment in premium food formulations.
It dissolves rapidly in both cold and hot water and is fully compatible with sweeteners, thickeners, emulsifiers, and protein ingredients. It effectively lowers system pH, inhibits the growth of mold, yeast, and spoilage bacteria, reduces the need for additional preservatives, and extends the product's shelf life.
The spray-dried granular structure significantly minimizes moisture absorption and caking issues. Packaging options include standard 25kg kraft paper bags with PE liners as well as small sample bags. The product can be stored sealed at room temperature without refrigeration, substantially reducing storage and transport-related losses for overseas customers.
We offer customization for powder fineness, acidity concentration, and sustained-release coated lactic acid powders based on specific formulation requirements. Free laboratory samples are provided for formulation testing, and we flexibly accommodate orders ranging from small batches for distributors to large-scale industrial orders. We provide complete export documentation and ensure rapid global shipping.
