Functional Ingredients Designed for the Spanish Market
High-purity botanical extractions and water-soluble plant protein isolates tailored for sports nutrition, functional baking, and clean-label beverages in Madrid, Barcelona, and across Iberia.
Spain's Plant-Based Shift: High Demand for Premium Plant Proteins
The Spanish plant-based food industry is undergoing a significant transformation. Once a niche market segment, the demand for clean-label, plant-derived proteins has reached unprecedented levels across Madrid, Barcelona, Valencia, and Andalusia. Driven by the "Realfooding" movement, clean label trends, and consumer demands for non-allergenic food sources, Spanish food manufacturers are rapidly reformulating products away from soy and wheat gluten towards highly functional, allergen-free proteins like pumpkin seed protein.
Pumpkin seed protein offers a unique combination of nutritional and functional advantages. Naturally rich in iron, zinc, magnesium, and essential amino acids (such as Arginine, Leucine, and Valine), it has become the ingredient of choice for B2B brands looking to create high-value products. Crucially for Spain's food sector, which operates under strict EFSA regulations, our pumpkin seed protein is derived without the use of chemical solvents. This aligns with Spanish consumers' demand for organic, clean, and minimally processed ingredients.
Dongguan Tsrel Biology Co., Ltd. serves as a crucial B2B partner, bridging the gap between raw plant extraction and complex industrial needs. By providing consistent particle size control, optimized solubility profiles, and dependable logistics directly to Spanish ports (such as Valencia, Barcelona, and Algeciras), we help manufacturers bypass supply bottlenecks and achieve consistent production cycles.
Technical Roadmap: Extraction Innovation & Functional Optimization
How Tsrel Biology engineers physical properties to maximize application performance in liquid, powder, and solid formulations.
Cold-Pressed Physical Extraction
By employing advanced screw-pressing technologies under strict temperature controls (<50°C), we preserve the delicate globulin and albumin protein structures, preventing denaturation and maintaining high nutritional bioavailability.
Microfluidization & Solubility
Our superfine milling processes achieve a highly uniform particle size distribution (<150 mesh). This provides excellent dispersion in Spanish RTD beverages, dairy alternatives, and protein shakes without the chalky mouthfeel common in standard plant proteins.
Natural Organoleptic Control
Utilizing natural steam-deodorization and precise heating curves, we reduce hexanal compounds responsible for raw "grassy" notes. This results in a mild, slightly nutty flavor profile that blends easily into diverse food matrixes.
Whole Seed Kernels & High-Fiber Plant Bases for Spanish Bakeries
Raw materials optimized for traditional and gluten-free baking sectors in Spain, supporting high clean-label and nutrient density requirements.
Industrial Power: Smart Sourcing & Global Logistics Resilience
To support major food brands in Spain, Dongguan Tsrel Biology Co., Ltd. has updated its production lines to support high-capacity, consistent runs. Our plant protein manufacturing facilities implement automated environmental monitoring, batch-to-batch tracking, and automated cold-press extraction. This ensures that every container delivered to Bilbao, Barcelona, or Valencia meets strict quality and performance metrics.
With an annual capacity exceeding 15,000 metric tons of plant protein, we provide reliable supply security for our Spanish customers. Operating our own modern labs enables us to run HPLC, GC-MS, and ICP-MS testing in-house, validating active levels (such as phytosterols) and verifying the absence of heavy metal and pesticide contamination prior to export. This streamlined testing cycle shortens shipping lead times, allowing Spanish purchasing managers to maintain lower warehouse inventory margins.
- Strict non-GMO declarations
- EU pesticide limit compliance
- Full batch trace documentation
- SGS, Eurofins, or custom 3rd party testing
- Custom packaging: 25kg paper sacks or 500kg super sacks
Regulatory Framework for Importing Into Spain
Navigating EU food import regulations is a key consideration for purchasing managers in Spain. All raw materials must comply with European Food Safety Authority (EFSA) criteria, EU Regulation (EC) No 396/2005 for maximum residue levels (MRLs) of pesticides, and Regulation (EC) No 1881/2006 for contaminants.
Dongguan Tsrel Biology Co., Ltd. provides comprehensive documentation with every shipment, including detailed Certificates of Analysis (COAs), allergen declarations, and non-GMO statements. This documentation helps streamline custom clearance procedures at major entry ports like Valencia or Barcelona. Additionally, our factories are ISO, HACCP, Kosher, and Halal certified, allowing our ingredients to fit seamlessly into diverse product lines.
Industrial Grade Raw Seeds & Organic Plant Protein

Frequently Asked Questions for Spanish Buyers
Key technical, regulatory, and logistics questions answered by our engineering and supply chain teams.
What is the typical shelf life and recommended storage for Spanish climates?
Our pumpkin seed protein powder has a shelf life of 24 months from the date of manufacture when stored in the original unopened packaging. For Spanish regions with high summer temperatures (such as Andalusia or Madrid), we recommend storing the product in a cool, dry warehouse below 25°C with a relative humidity under 60%. This helps preserve the fat profile and prevents oxidation.
How does pumpkin seed protein compare to pea or soy protein in terms of allergens?
Unlike soy and wheat, which are classified as major allergens under EU law, pumpkin seed protein is naturally allergen-free. It does not require allergen labelling on retail packaging under EU Regulation No 1169/2011, making it a reliable choice for clean-label and hypoallergenic products.
What is the water solubility index (WSI) of your 70% powder?
Our 70% protein powder is processed for high solubility, achieving a WSI of 75-80% at neutral pH. This dispersion makes it suitable for ready-to-mix (RTM) powders, plant milks, and liquid beverages without significant sedimentation.
What documentation do you provide for Spanish customs clearance?
We supply a complete document package, including the Certificate of Analysis (COA), Phytosanitary Certificate, Non-GMO Declaration, Allergen-Free Certificate, Packing List, Commercial Invoice, and Bill of Lading. We also offer custom testing reports from third-party certifiers like SGS or Eurofins upon request.
What are your minimum order quantities (MOQ) and lead times?
Our standard MOQ for direct factory shipments to Spain is 1,000 kg (1 metric ton). Standard sea freight transit time from our facilities in China to Spanish main ports (Barcelona, Valencia, Bilbao) is approximately 30 to 35 days. Fast-track options via air freight or rail freight can be arranged for sample batches or urgent production needs.
