Products Description
Positioning Statement
A beverage-grade hydrolyzed rice protein designed for clear, great-tasting, and highly soluble liquid nutrition systems.
Product Introduction
Hydrolyzed Rice Protein is derived from high-quality rice protein and produced through a controlled hydrolysis process to improve solubility and dispersibility in water systems.It contains ≥90% protein (main grade) and ≥60% peptides, offering good water compatibility and functional performance in liquid formulations.
The product is available in 90% and 95% protein grades and is characterized by fast dispersion, good solubility, and a mild peptide-related sensory profile.
Core Advantages That Define Performance
🥇 Breakthrough Transparency
Truly instant dissolution in water systems, forming a clear and transparent solution free from sediment and visible impurities.
It is designed to serve as a reliable base for clean-label functional beverage formulations requiring visual clarity and stability.
🎨 Multi-Layered Sensory Profile
Unlike conventional plant proteins with flat or chalky taste profiles, this rice peptide offers a balanced sweet–sour–mild bitterness structure, with a clean finish and no lingering aftertaste.
Its sensory behavior integrates well into complex beverage systems such as fruit-based drinks and sports nutrition formulations, enhancing overall flavor depth.
⚡ Flexible Dual-Grade System
The product is available in two purity levels to support different formulation needs, balancing performance, taste, and cost efficiency.
A standard-grade option provides a reliable solution for mainstream beverage applications, while a higher-purity option is designed for premium formulations requiring enhanced protein content and cleaner positioning.
Both grades are engineered to ensure consistent solubility, good dispersibility, and beverage-friendly sensory performance.

Application Guide - How to Incorporate This Product into Your Formulation
Our hydrolyzed rice peptide features three core properties - instant solubility in both cold and hot water, crystal-clear solution, and clean flavor - making it perfectly adaptable to a wide range of ready-to-drink beverage systems. Below are verified application formulation references:
Application 1: Clear Protein Water
Recommended Dosage: 0.15% – 0.25% of total formulation
Recommended Co-ingredients: Citric acid 0.40% – 0.50%, malic acid 0.20%, honey 7% – 9%
Process Tips: Dry-mix rice peptide with acidulants and sweeteners first, then dissolve in water at 55°C, homogenize at 40MPa for 30 minutes, sterilize at 120°C for 30 minutes
Finished Product Profile: Crystal clear solution, balanced sweet-sour taste, minimal bitterness, clean finish
Application 2: Functional RTD Tea Beverages
Recommended Dosage: 0.20% – 0.30%
Recommended Co-ingredients: Tea extracts, natural sweeteners (stevia, monk fruit), vitamin C
Process Tips: Pre-disperse peptide powder in a small amount of warm water before mixing with tea broth - avoid direct addition to high-temperature tea to prevent localized overheating
Finished Product Profile: Does not mask tea aroma, no turbidity or sedimentation, maintains the tea's original clarity
Application 3: Post-Workout Recovery Beverages
Recommended Dosage: 0.25% – 0.40%
Recommended Co-ingredients: Electrolytes (sodium, potassium, magnesium), natural fruit flavors, branched-chain amino acids (optional)
Process Tips: Pre-mix peptide powder with electrolytes before dissolution; adjust pH to 4.5 – 6.0 to ensure dissolution stability
Finished Product Profile: Light, non-heavy mouthfeel - no chalkiness or astringency typical of traditional protein beverages
Formulation Note: The best flavor performance is achieved at around 0.20% rice peptide dosage - minimal bitterness with balanced sweet-sour taste. For stabilizer systems, reference formulations include CMC-Na 0.12%, agar 0.08%, and gelatin 0.12%. Our technical team is available to provide customized formulation support.
Real-World Case Studies - Market Trends in Action
Case Study 1: The Global Wave of Clear Protein Beverages
In recent years, clear plant-based protein beverages have emerged as one of the fastest-growing segments in the global beverage industry. In 2022, clear plant proteins derived from rice and pea achieved their first commercial-scale application, fundamentally transforming the traditional perception of protein drinks as "thick and heavy". These products integrate seamlessly into high-acid systems (pH as low as 2.5) including citrus beverages, carbonated drinks, coffee, and tea - without separation or sedimentation.
Case Study 2: Plant-Based Giant's Cross-Category Validation
In January 2026, global plant-based food leader Beyond Meat launched its first clear protein drink line, Beyond Immerse - which sold out within days of release. The product is positioned as a "crisp, clear protein beverage" rather than a traditional thick shake. Soon after, leading clean protein brand Koia also launched plant-based clear protein sodas in the U.S. market. This trend signals a clear shift - clarity, refreshment, and plant-based are becoming the new benchmarks for RTD protein beverages.

FAQ
Q: Why should I select the 80% rice protein grade instead of 90% rice protein isolate for liquid product formulas?
A: Higher-purity protein materials such as the 90% grade excel at boosting protein content per gram of powder. However, they tend to cause excessive thickening and high viscosity when used in liquid systems, along with an undesirable chalky taste texture. The 80% rice protein grade is purpose-built to optimize liquid-state performance: it offers outstanding dispersion and suspension capacity, delivers a lighter, purer mouthfeel, and brings far better cost performance for commercial liquid formulations.
Q: Protein measured at 82.1% in your COA - why do my third-party test results sometimes come back lower?
A:Please pay attention to the conversion factor. We use 6.25 (the rice protein-specific factor). If a third-party lab incorrectly uses soy's 5.71 or the generic 6.38, results will read 2–3% lower. We can provide method comparison guidance to ensure testing consistency.
Q: Is the 80% rice protein grade compatible with vegan formulas?
A: Absolutely. It is purely plant-sourced and fully compliant with vegetarian and vegan production requirements.
Q: What is the minimum order quantity and sample policy?
A: Samples (500g–1kg) are provided free of charge, with shipping costs only. Standard MOQ is 500 kg. For startup brands, 100 kg small-batch trial runs can be negotiated.
Q: Can the 80% rice protein grade be mixed with other protein raw materials?
A: Yes. It is widely blended with pea protein and soy protein to attain balanced amino acid spectra and create synergistic functional properties.
