Total protein: ≥ 90%
Next-Generation Bioactive Short-Chain Rice Peptide ($\ge 90\%$ Protein) for High-Transparency, Flavor-Sensitive, and Clean-Label Formulations.
100% Plant-Based, Non-GMO, Hypoallergenic, and Engineered to Mimic Natural Enzymatic Protein Digestion.
Standard plant protein isolates often suffer from poor solubility, heavy sedimentation, and intense beany off-notes. KEEP INGREDIENTS Fully Hydrolyzed Rice Peptide 90% utilizes advanced targeted enzymatic hydrolysis to simulate human digestive mechanisms, cleaving macro-proteins into low-molecular short-chain oligopeptides (189–2,000 Da).
Direct Absorption: Reaches an in-vitro digestibility of 99.9%. These short-chain peptides bypass stomach digestion and are absorbed directly in the small intestine, rapidly delivering essential amino acids.
Clean-Label & Hypoallergenic: 100% plant-derived and vegan-friendly. Free from soy, dairy, nuts, and artificial colors, flavors, or preservatives. Gluten content is strictly controlled at ≤20 ppm.
