Hydrolyzed Rice Peptide Manufacturer | Debittered Clear Soluble Rice Peptides
Rice Protein Peptide is a premium functional ingredient derived from high-quality rice protein (Oryza sativa L.) via advanced bio-enzymatic hydrolysis technology.
Using targeted enzymatic hydrolysis, large-molecule rice protein is broken down into small-molecular-weight peptides with rapid absorption and high bioavailability. Unlike conventional hydrolyzed proteins that produce bitter hydrophobic peptide fragments, our product solves the bitterness issue through precise enzymatic control and specialized debittering technology. It features a neutral taste and light yellow appearance, ensuring it won't alter the flavor or color of end products, making it a "stealth fortification" ingredient for high-end formulations.
As a low-allergen ingredient, it is well-tolerated by sensitive populations, including infants, the elderly, and those with digestive disorders. Each batch is sourced from non-GMO rice and undergoes strict quality control to maintain consistent purity and functionality. Ideal for European and American high-end sports nutrition brands, functional beverage developers, medical food manufacturers, and infant food producers, it meets the demand for pure, high-performance, and clean-label ingredients.
