How CLEARTEIN® is Created
How CLEARTEIN® is Created
- Protein is checked for quality, mixed with water, and prepared for processing.
- Natural food-grade enzymes break the protein into smaller, clearer, more soluble peptides.
- The filtration process removes color, odor, and impurities while gently purifying and sterilizing the peptide solution for a clean, safe final base.
- Optional step where pH is adjusted to create acidified peptides for formulation flexibility.
- The purified liquid is dried into a fine powder that stays clear in beverages.
Choosing Neutral or Acidified Peptides
- Neutral CLEARTEIN® is great for RTMs and neutral beverages that need a clean, mild flavor.
- Acidified CLEARTEIN® is optimized for acidic or carbonated beverages where low pH helps maintain clarity and stability.

What is CLEARTEIN®?
CLEARTEIN® is NURA’s clear protein platform developed for modern food, beverage, and supplement applications. Unlike traditional protein powders, CLEARTEIN® uses hydrolyzed peptides optimized for high solubility, optical clarity, and low viscosity, making it purpose-built for lighter, more refreshing formats.
What applications is CLEARTEIN® best suited for?
CLEARTEIN® is designed for any application where clarity, texture, and clean dispersion matter. Primary targets include protein waters, hydration drinks, sports beverages, juice-style RTDs, fruit-flavored stick packs, protein shots, and RTM powders. It also performs well in smoothies, gummies, sauces, and other protein-fortified food and beverage formats.
What protein sources are available in CLEARTEIN®?
CLEARTEIN® is available in pea, rice, soy, whey, and yeast protein options, with blended formats also supported. Pea and rice are strong fits for vegan and plant-based positioning, soy brings a familiar nutritional profile, whey offers dairy-based protein quality recognition, and yeast provides a differentiated vegan option with a complete amino acid profile.
What is the difference between neutral and acidified CLEARTEIN®?
Neutral and acidified CLEARTEIN® options are designed to support different formulation needs. Acidified versions are often a better starting point for bright, tart, refreshing profiles such as lemon-lime, citrus, berry lemonade, and tropical concepts. Neutral versions are typically a better fit for smoother, milder systems like vanilla, chocolate, coffee, matcha, and savory or creamy applications.
Why does CLEARTEIN® use low molecular weight peptides?
Molecular weight is the primary driver of how a protein behaves in solution, influencing solubility, viscosity, clarity, and mouthfeel. CLEARTEIN® is built around a dominant peptide fraction below 500 Da, roughly 36 times smaller than standard whey protein at 18,000 Da. That size advantage is what allows CLEARTEIN® to dissolve cleanly, stay clear, and deliver a light drinking experience where conventional protein systems fall short.
Does CLEARTEIN® have bitterness or off-notes?
Hydrolyzed proteins can carry bitterness, and CLEARTEIN® is no exception. Sensory performance varies by source: soy peptide has the cleanest profile, acidified pea peptide is a solid middle ground, and rice peptide shows the most noticeable off-notes. Bitterness is also dose-dependent, and keeping inclusion at or below 5% in RTD formats is the recommended starting point across all sources.
Is CLEARTEIN® stable under heat processing?
Yes. As a hydrolyzed protein, CLEARTEIN® is inherently heat-stable. Unlike intact proteins, it will not denature, gel, or spike viscosity under intense thermal treatments. It has performed well in popsicle and gummy applications, and UHT pilot testing is underway to confirm exact parameters.
Is CLEARTEIN® allergen-free?
It depends on the protein source. Pea, rice, and yeast options are free from major regulated allergens and are the right fit for allergen-conscious formulations and free-from positioning. Soy and whey are major allergens and carry standard labeling obligations.
