Advanced botanical extraction solutions engineered for superior bioavailability, neutral flavor, and functional stability.
Understanding shifting consumer purchasing paradigms and functional ingredient evolution.
The global food industry is experiencing an unprecedented structural transition towards sustainable, functional plant-derived proteins. Driven by regulatory mandates on environmental sustainability, escalating allergen concerns associated with dairy and soy, and consumer preferences for clean-label raw materials, industrial B2B buyers are diversifying their ingredient portfolios.
High-purity nut and seed proteins—specifically derived from premium hemp seeds, sunflower seeds, chickpeas, and specialty yeast fermentations—are filling critical gaps. These alternatives offer superior amino acid ratios, hypoallergenic properties, and functional profiles suitable for clean-label declarations.
To assist procurement managers and food scientists in selecting the ideal botanical matrix, we present a comparative analysis of primary plant protein classes processed by Dongguan Tsrel Biology Co., Ltd.:
| Protein Type | Purity Range | Key Amino Acids | Functional Strengths |
|---|---|---|---|
| Hemp Seed Protein | 50% - 70% | Edestin & Albumin (Arginine) | Hypoallergenic, Digestive Support, Clean Label |
| Yeast Protein Isolate | 70% - 80% | Leucine, Isoleucine, Valine | High Solubility, Sustainable Fermentation |
| Chickpea Isolate | 75% - 85% | Lysine, Threonine | Emulsification, Neutral Flavor, Low Viscosity |
| Sunflower Seed | 50% - 90% | Glutamic acid, Aspartic acid | Cold-pressing Stability, Low Fat, Allergen-free |

Custom-formulated vegetable and nut protein systems targeted at global market requirements.
Our yeast isolates and hemp seed proteins provide complete BCAAs essential for muscle synthesis. They are engineered for minimal grittiness and high dispersing capability in dry powder mixes and RTD sports shakes.
Achieving stability in low pH environments is critical. Our water-soluble fava bean isolates and chickpea protein isolates maintain suspension, preventing phase separation in almond, oat, and soy milk formulas.
Textured vegetable proteins (TVP) and hydrolyzed wheat proteins are formulated to enhance viscoelastic networks in baked matrices. They increase protein density without sacrificing the structural crumb or shelf stability.
Our commitment to clean extraction processes and next-generation nutritional engineering.
Transitioned from hexane-solvent extraction to advanced supercritical CO2 extraction for nut and seed processing. This preserves the functional integrity of labile proteins and maintains a chemical-free profile.
Incorporated specific food-grade endopeptidases and exopeptidases. This process cleaves complex proteins into bioavailable peptides, reducing bitter notes and improving solubility at neutral pH levels.
Developing next-generation clean-label physical barriers. These systems mask typical green and earthy notes of plant extracts, minimizing the need for artificial flavor masks in final formulations.
Traditional methods of plant protein isolation rely heavily on high-temperature acid precipitation. These processes run the risk of denaturing protein molecules and damaging the functional benefits that food producers require.
At Dongguan Tsrel Biology, our R&D initiatives focus on mild extraction techniques that preserve the natural structure of proteins. By utilizing subcritical water and mechanical membrane separation, we maintain high solubility indexes and water-binding capacities across our entire portfolio.
R&D Objective for 2025-2026:
Achieving a 98% solubility index in cold water profiles for our premium hemp and yeast protein lines, eliminating sedimentation in RTD beverages.

These ingredients are widely used in functional foods, nutritional supplements, sports nutrition products, dairy alternatives, meat alternatives, beverages, bakery products, and health food applications.
Innovation is a key driving force behind our growth. Supported by an experienced research and development team, Dongguan Tsrel Biology continuously explores new technologies and application solutions to meet the evolving demands of the global food and nutrition industries. The company also provides customized ingredient solutions to help customers optimize product formulations, improve nutritional profiles, enhance texture, and create clean-label products.
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. This commitment enables us to deliver dependable products that meet the rigorous requirements of global customers.









Meeting international quality and safety benchmarks for industrial food manufacturing.
Our raw materials conform to global quality programs. Production processes are audited under ISO 22000, HACCP, Halal, Kosher, and USDA Organic standards, ensuring seamless custom clearance and market access.
We work with international logistics providers to manage ocean freight, intermodal transport, and warehousing networks. We offer door-to-door shipping solutions, customized palletization, and oxygen-barrier packaging.
We perform rigorous batches testing for heavy metals, pesticide residues, and microbiological contaminants. Independent test reports (SGS/Eurofins) are issued with every batch for quality validation.
Answering key technical and logistical questions from global buyers and food scientists.
Yeast protein isolate is derived from the controlled fermentation of Saccharomyces cerevisiae. It serves as a sustainable option that avoids soil degradation issues. Functional benefits include an allergen-free profile, clean taste without the off-flavor notes of soy, and a complete amino acid profile rich in BCAAs, making it excellent for sports nutrition products.
We utilize low-temperature mechanical processing and dry milling to separate target fats without chemical heat damage. This minimizes lipid oxidation, which is the primary cause of off-flavors. Our advanced isolation methods yield a clean, light powder with a mild, nutty aroma that blends smoothly into beverages.
Our standard packaging consists of food-grade, vacuum-sealed multi-kraft paper bags with PE inner liners (typically 20kg or 25kg net weight), or drum packaging for specialized isolates. Our standard MOQ is 1 metric ton (1,000 kg). However, trial orders of smaller quantities (starting from 100 kg to 500 kg) can be arranged for laboratory testing and industrial trial purposes.
Yes, our seed, nut, and botanical proteins—such as hemp, chickpea, sunflower seed, and yeast—are naturally gluten-free and 100% Non-GMO. We source crops from dedicated cultivation bases that undergo testing to prevent cross-contamination from allergens like wheat and soy, keeping our supply lines clean-label compliant.
