Application
Sports Nutrition & Post-Workout Protein Formulas
Hydrolyzed rice protein is widely used in sports nutrition products due to its high digestibility and fast amino acid absorption. With a low molecular weight peptide structure and a balanced amino acid profile including BCAAs (leucine, isoleucine, valine), it supports muscle recovery, lean muscle maintenance, and plant-based performance formulas. It is ideal for vegan protein powders, recovery blends, and plant-based pre- and post-workout supplements.
Plant-Based Dietary Supplements
As a hypoallergenic and dairy-free protein source, hydrolyzed rice protein powder is commonly used in capsules, tablets, and blended protein supplements. Its good solubility and mild taste make it suitable for clean-label, non-GMO, and allergen-free formulations. It is an excellent alternative to soy protein and whey protein in vegan dietary supplements targeting general wellness, weight management, and senior nutrition.
Functional Foods & Plant-Based Beverages
Hydrolyzed rice protein is highly compatible with functional foods and ready-to-mix beverages due to its smooth texture and water solubility. It is frequently used in meal replacements, protein bars, dairy-free drinks, and plant-based nutritional beverages. Its light color and neutral flavor profile allow easy formulation into high-protein functional food products for global markets.
Hydrolyzed Rice Protein Manufacturing Process
ProVita Biotech’s Hydrolyzed Rice Protein Powder is produced through a controlled enzymatic and physical processing system to ensure high purity, excellent solubility, and stable nutritional value. The entire manufacturing process follows strict food-grade quality management standards and complies with international regulations.
Step 1: Raw Material Selection – Rice
High-quality non-GMO rice is selected as the raw material. The rice undergoes inspection to ensure it meets food safety standards before entering production.
Step 2: Soaking & Grinding
The rice is soaked to soften the structure and then finely ground to release starch and protein components. This step prepares the material for efficient enzymatic processing.
Step 3: Starch Hydrolysis
Through controlled enzymatic hydrolysis, starch components are broken down and removed. This step increases protein concentration and improves digestibility while maintaining the natural amino acid profile.
Step 4: Horizontal Filtration
The hydrolyzed slurry undergoes advanced filtration to remove residual fiber, impurities, and insoluble components. This ensures improved clarity, purity, and product safety.
Step 5: Homogenization
The protein solution is homogenized to ensure uniform molecular distribution and consistent quality. This step enhances solubility and stability in food and supplement formulations.
Step 6: Spray Drying
The purified liquid protein is spray-dried under controlled temperature conditions to form a fine, light-yellow powder with good water solubility and uniform particle size.
Final Product: Hydrolyzed Rice Protein Powder
The final product achieves 75% protein purity as a standard specification and passes international food safety standards and third-party quality testing. It is manufactured under strict quality control systems, ensuring compliance with microbiological, heavy metal, and contaminant limits.
Available specifications include 75%, 80%, 85%, 90%, 95% protein content, or customized food-grade specifications according to client requirements. ProVita Biotech ensures consistent batch-to-batch quality, making it a reliable bulk Hydrolyzed Rice Protein Powder supplier in China for sports nutrition brands, dietary supplement manufacturers, and functional food producers worldwide.
Hydrolyzed Rice Protein Benefits
- Supports muscle growth and recovery with a balanced amino acid profile containing all nine essential amino acids, helping stimulate muscle protein synthesis and promote lean muscle repair when combined with proper training and nutrition.
- Rich in BCAAs (leucine, isoleucine, valine), making it ideal for sports nutrition, post-workout protein powders, and plant-based performance supplements.
- Enhanced nutrient absorption due to enzymatic hydrolysis, producing low molecular weight peptides (<2000 Da) that improve bioavailability and digestive tolerance compared to conventional rice protein isolate.
- Supports weight management by promoting satiety and appetite control; high protein intake helps reduce hunger and supports metabolism during calorie-controlled or fat-loss programs.
- May support cardiovascular health, as certain rice protein peptides have shown potential ACE-inhibitory activity, helping maintain healthy blood pressure levels within the normal range.
- Demonstrates antioxidant properties that help reduce oxidative stress and support overall cellular health, contributing to improved recovery and wellness.
- Hypoallergenic and allergen-friendly, naturally free from lactose, dairy, soy, and gluten, making it suitable for sensitive individuals and clean-label dietary supplement formulations.
- 100% plant-based and vegan protein derived from Oryza sativa L., widely used in functional foods, meal replacements, plant-based beverages, capsules, and tablets.
- Excellent water solubility with smooth texture and mild flavor, enabling easy formulation in protein shakes, high-protein drinks, and blended supplement powders.
- In cosmetic applications (cosmetic grade), hydrolyzed rice protein peptides help improve skin hydration by forming a protective film that reduces transepidermal water loss and enhances moisture retention.
- Supports anti-aging effects in skincare by promoting collagen production, improving skin elasticity, and helping reduce the appearance of fine lines and wrinkles.
- Provides antioxidant protection to the skin, helping defend against environmental stress and premature aging.
- Strengthens and repairs hair by penetrating the hair shaft, improving elasticity, reducing breakage, and enhancing shine in shampoos and conditioners.
- Offers soothing and calming properties for sensitive or irritated skin by helping reduce redness and inflammation.
- Cosmetic-grade hydrolyzed rice protein differs from food-grade material in regulatory standards and processing controls; food-grade hydrolyzed rice protein is manufactured under strict international food safety standards and third-party quality testing for dietary supplements and functional foods.

No. Brown rice protein typically refers to rice protein concentrate or isolate without enzymatic hydrolysis. Hydrolyzed Rice Protein undergoes enzymatic processing to break proteins into smaller peptides, improving digestibility, solubility, and bioavailability.
Dietary supplement and sports nutrition applications are currently more popular in global markets. However, cosmetic-grade hydrolyzed rice protein is widely used in skincare and haircare products for moisturizing and conditioning effects. Food-grade and cosmetic-grade materials follow different regulatory standards.
