Product Portfolio
Engineered Plant Protein Ingredients
Equipped with advanced manufacturing facilities and modern processing technologies, Dongguan Tsrel Biology offers a comprehensive range of vegetal proteins designed to satisfy diverse application matrices.
🌱
Soy Protein (Isolates & Concentrates)
Derived from non-GMO soybeans, our soy protein isolates deliver a minimum of 90% protein content on a dry basis. They feature excellent gelling properties, high water binding capacity, and superior emulsification. This makes them ideal for structural improvement in meat alternatives, emulsion stabilization in dairy alternatives, and nutritional fortification in sports nutrition blends.
- PDCAAS (Protein Digestibility-Corrected Amino Acid Score) value of 1.0
- Exceptional solubility curves across broad pH environments
- Neutral flavor profiles minimizing the need for masking agents
🌾
Pea Protein
A highly digestible, hypoallergenic alternative sourced from premium yellow peas. Naturally free from gluten, dairy, and soy allergens, it offers high levels of branched-chain amino acids (BCAAs).
🌾
Rice Protein
An organic-compliant, allergen-friendly protein isolated from brown rice. It boasts an excellent amino acid profile close to breast milk, making it highly valuable in infant formulas and clinical nutrition solutions.
🍞
Wheat Protein & Specialty Blends
Our active wheat gluten and hydrolyzed wheat protein series offer unique viscoelasticity. These parameters are essential for generating authentic chewiness and structural integrity in bakery goods and texturized vegetarian meats. In addition, our custom specialty plant proteins provide tailored nutritional profiles to help manufacturers achieve ideal clean-label standards.
Market Applications
Delivering Versatility Across Industry Sectors
Vegetal proteins are no longer confined to niche dietary products. Today's consumers demand functional food products with improved sensory traits, clean ingredients, and sustainable origins. Dongguan Tsrel Biology's protein solutions are meticulously engineered to perform under diverse industrial conditions:
Functional Foods & Nutrition
Excellent powder flowability and dispersion characteristics for easy processing of ready-to-mix (RTM) sports nutrition, meal replacements, and health supplements.
Meat & Dairy Alternatives
Provides texture replication and juice-retention capacity in vegetarian burger patties, sausages, cheese alternatives, and plant-based milks.
Beverage & Bakery Systems
Maintains thermal stability in acidic and neutral beverage systems while enhancing crumb structures and moisture retention in gluten-free bakery lines.
Factory & Quality Standards
Rigorous Standards from Source to Shipment
Quality and food safety are integrated into every stage of production. From raw material sourcing and processing to final testing and packaging, strict quality control procedures are implemented to ensure product consistency, purity, safety, and compliance with international standards.

Case Studies & Formulation Achievements
Proven Success in Global Markets
We don’t just supply raw protein powder; we deliver solutions. Explore our successful formulations and integration projects with global brand owners:
Case Study 1: Clean-Label Soy Protein in Plant-Based Meat Alternatives
An EU-based alternative meat brand wanted to eliminate synthetic binding additives from their burger patties. We developed a customized soy protein isolate with tailored gelation properties. This replacement allowed them to completely substitute artificial binders, achieving a cleaner label while retaining natural firmness and juiciness.
Result: 35% texture retention improvement & clean label verified.
Case Study 2: Low-Viscosity Pea Protein in RTD Nutritional Beverages
A major sports nutrition brand faced issues with chalkiness and protein settling in their ready-to-drink vegan protein shakes. Dongguan Tsrel Biology supplied a highly micronized, low-viscosity pea protein isolate. The smaller particle size distribution significantly improved solubility, keeping the protein suspended in liquid without altering the sensory profile.
Result: 100% elimination of settling & improved creamy mouthfeel.
