Bridging premium raw materials, state-of-the-art bio-extraction, and reliable industrial supply lines to power global health brands.
Dongguan Tsrel Biology Co., Ltd. is a professional China vegetal protein manufacturer specializing in the research, development, production, and supply of high-quality plant protein ingredients for food, beverage, and nutritional applications. With a strong focus on innovation, sustainability, and quality assurance, the company is dedicated to providing reliable plant-based ingredient solutions to customers worldwide.
Equipped with advanced manufacturing facilities and modern processing technologies, Dongguan Tsrel Biology offers a comprehensive range of vegetal proteins, including soy protein, pea protein, rice protein, wheat protein, and other specialty plant proteins like high-purity peanut protein. These ingredients are widely used in functional foods, nutritional supplements, sports nutrition products, dairy alternatives, meat alternatives, beverages, bakery products, and health food applications.
R&D and Custom Formulations
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.
Peanut Protein: Sourcing Dynamics for Global Enterprises
As consumer demand for clean-label, allergen-conscious, and high-functionality plant proteins accelerates, global B2B procurement is undergoing a fundamental shift.
Industrial peanut protein (derived from premium Arachis hypogaea) has emerged as a premium alternative to traditional soy and wheat proteins. The global corporate demand is driven by distinct functional characteristics: exceptional water-binding capacity, fat absorption capabilities, and a mild, nutty organoleptic profile. However, procurement officers in North America, Europe, and the APAC region face critical friction points when sourcing at scale.
Nutritional Integrity & PDCAAS
Peanut protein boasts an excellent amino acid profile, particularly rich in arginine, glutamic acid, and aspartic acid. Global food scientists leverage it to blend with pea or rice protein, elevating the overall Protein Digestibility-Corrected Amino Acid Score (PDCAAS).
Aflatoxin Mitigation
The primary compliance hurdle for imported peanut derivatives is mycotoxin control. Top-tier Chinese manufacturers utilize advanced optical sorting, real-time testing, and subcritical extraction technologies to guarantee Aflatoxin B1/B2/G1/G2 levels below regulatory thresholds (e.g., EU's 4.0 μg/kg limits).
Clean-Label Non-GMO Supply
Unlike soy, which faces GMO-contamination concerns, Chinese peanuts are inherently Non-GMO. This allows manufacturers to formulate products that fit USDA Organic, Non-GMO Project Verified, and European Clean-Label classifications.
Macro-Industry Solutions & Formulation Integration
Optimizing plant protein behavior across diverse food matrices requires deep molecular understanding and application engineering.
Peanut protein isolates (PPI) and concentrates (PPC) are not just nutritional additives; they are functional macromolecules that dictate food texture, mouthfeel, and shelf life. Our application engineering teams have designed tailored solutions for various sectors:
-
✓
Plant-Based Meat Analogs: High-moisture extrusion (HME) of defatted peanut flour produces fibrous, meat-like textures with excellent tensile strength, mimicking chicken or beef fibers far better than soy alone.
-
✓
Sports Nutrition & Meal Replacements: Highly soluble peanut protein peptides provide quick digestion and nitrogen retention, blending smoothly without the chalky texture typical of yellow pea protein.
-
✓
Bakery & Confectionery: Serves as a clean-label emulsifier and egg replacer. Its high foaming capacity stabilizes meringues, cookies, and protein-enriched baked goods while enhancing crust browning via the Maillard reaction.
Typical Physicochemical Specifications
For product designers looking to optimize formulations, our standard grade offers:
| Protein (Dry basis) | ≥ 80.0% / 90.0% (Isolate Grade) |
| Moisture | ≤ 6.0% |
| Fat Content | ≤ 1.5% |
| Ash | ≤ 4.5% |
| Total Plate Count | < 10,000 cfu/g |
Technical Processing Roadmap & Extractions
How Dongguan Tsrel Biology leverages state-of-the-art biochemistry to isolate highly functional plant proteins.
The traditional method of hot-pressing peanuts for oil recovery denatures the proteins, rendering them useless for food systems due to low NSI (Nitrogen Solubility Index). To overcome this, our processing plants implement a low-temperature, subcritical, and enzymatic extraction methodology.
Step 1: Low-Temperature Defatting
Using advanced solvent extraction at temperatures under 60°C. This maintains the structural integrity of the globulin proteins (arachin and conarachin), preserving their native emulsifying capabilities.
Step 2: Alkaline Extraction & Isoelectric Precipitation
Solubilizing the protein fractions at pH 8.0 - 9.0, followed by centrifugation to remove insoluble fiber. The supernatant is then adjusted to pH 4.5 (the isoelectric point of peanut globulins) to precipitate high-purity protein curd.
Step 3: Enzymatic Modification (Optional)
Controlled hydrolysis utilizing food-grade endoproteases breaks down long-chain polypeptides into bioactive peptides, boosting solubility to >90% even in acidic environments.
Step 4: Microfiltration & Spray Drying
Ultrafiltration removes residual sugars and mineral salts. The concentrated liquid is flash spray-dried in a GMP-compliant tower to yield a free-flowing, ultra-fine powder with an excellent sensory profile.
Global Commercial Footprint & Supply Chain Resiliency
Leveraging China's agricultural dominance and modern shipping logistics to secure continuous raw material access.
China is the world's largest producer of peanuts, contributing over 35% of global output. This vast domestic supply chain gives Chinese factories an unmatched raw material stability advantage, shielding global buyers from the market volatility seen in other oilseed markets.
Dongguan Tsrel Biology Co., Ltd. sits strategically in the Pearl River Delta, one of the world's most connected shipping and logistics hubs. By pairing our regional raw-material collection networks in Shandong and Henan provinces with local shipping capabilities, we ensure our global partners receive consistent, cost-effective shipping lead times to major ports across Europe, North America, and Southeast Asia.
Supply Chain Advantages at a Glance
- ✓ Stable raw material buffer stocks protecting against price spikes.
- ✓ Dual-factory operational redundancy ensuring zero production interruptions.
- ✓ Partnerships with major logistics lines for guaranteed container access during peak freight seasons.
