Engineered at the molecular level to exhibit exceptional foaming, gelling, and emulsification performance across dairy, bakery, and sports nutrition sectors.
Over the past decade, the global plant protein market has experienced a radical structural transition. Traditional plant sources, such as soy and wheat gluten, are facing consistent scrutiny due to increasing allergenicity concerns and genetic modification risks. Concurrently, while pea protein has established a footprint, its distinct botanical flavor and functional limitations in acidic environments present unique hurdles to product developers. This is where Potato Protein Isolate stands out as the ultimate Clean Label ingredient.
Potato protein features a highly favorable amino acid composition, particularly rich in Essential Amino Acids (EAAs) and Branched-Chain Amino Acids (BCAAs) such as Lysine, Leucine, and Isoleucine. In fact, its nutritional profile rivals whey protein isolate, showing a high Protein Digestibility-Corrected Amino Acid Score (PDCAAS). Beyond nutrition, its macromolecular structure excels in thermal gelation, cold gelation, and long-term emulsion stability.
As Sri Lanka emerges as a pivotal hub for food processing and export-oriented confectionery manufacturing in South Asia, the demand for high-performance vegetal protein has surged. The local commercial segment, driven by tourist consumption and urban lifestyle adjustments in regions like Colombo, Gampaha, and Kandy, is pushing for high-protein, allergen-free, and Halal-certified options.
Furthermore, local industries are navigating challenging macroeconomic supply chain factors. By substituting animal proteins (such as egg white albumin or milk derivatives) with low-dosage, high-functionality potato proteins, Sri Lankan manufacturers can effectively stabilize ingredient costs while upgrading their clean-label certifications. This transition is crucial for exporting processed foods from Sri Lanka to strictly regulated markets in the European Union, Australia, and the Middle East.
Unlike soy, gluten, and dairy, potato protein is inherently free from major allergens. This allows manufacturers to label products as "Gluten-Free," "Soy-Free," and "Dairy-Free," opening doors to highly profitable health-conscious markets.
Boasting a high PDCAAS score, our potato protein is exceptionally rich in Lysine and Valine, making it highly bioavailable and an excellent fit for sports nutrition and functional medical foods.
Optimized extraction ensures minimal residual off-notes, ensuring the delicate flavor profiles of Sri Lankan coconut drinks, confectionery, and functional teas remain clean and unaltered.
At Dongguan Tsrel Biology Co., Ltd., we utilize a proprietary low-temperature extraction technology to yield high-purity protein fractions while maintaining the native state of the proteins. The extraction pipeline is strategically engineered around five key phases:
Understanding the functional variations helps food scientists formulate products with precision:
| Parameter | Potato Protein Isolate | Pea Protein | Soy Protein Isolate |
|---|---|---|---|
| Protein Content | 90% | 80% | 90% |
| Water Solubility | Excellent (80-95%) | Moderate (35-50%) | Good (60-70%) |
| Foaming Capacity | Superb (Rivals Egg Albumin) | Low | Moderate |
| Allergen Warning | None (Hypoallergenic) | None | Major Allergen |
Customized functional properties optimized for regional preferences, raw material availability, and process requirements.
Sri Lanka has a massive global advantage in coconut milk and coconut water processing. Combining our 90% water-soluble potato protein isolate with coconut fats enables the manufacturing of stable, high-protein plant milks, ready-to-drink (RTD) vegan shakes, and dairy-free yogurts that do not separate or deposit during heat pasteurization/UHT treatments.
With volatile local egg prices and storage issues, local confectioners in Sri Lanka can replace egg whites in meringues, marshmallows, macarons, and biscuits. The high patatin protein component in potato protein delivers rapid foaming and sturdy mechanical crumb structures, lowering recipes' costs by up to 25%.
Sri Lanka's aquaculture farms along the northwestern and eastern coasts require top-tier nutrient feed for premium shrimp export. Feed-grade potato protein powder provides high digestibility, excellent lysine ratios, and solid binding capacity, reducing water contamination in aquaculture ponds compared to traditional fishmeal feeds.

Comprehensive technical clarifications addressing compliance, functionality, logistics, and applications for Sri Lankan buyers.
Our premium potato protein isolate exhibits comparable foaming volume and foam stability to egg white albumin. Thanks to the native patatin fraction (approx. 40 kDa), it forms a highly cohesive viscoelastic layer at air-water interfaces, making it ideal for eggless meringues, sponge cakes, and local bakery products manufactured in Colombo.
Yes. All our vegetal protein products, including potato protein isolates and peptides exported to Sri Lanka, are processed from non-GMO raw materials under strict GMP controls and carry globally recognized Halal and Kosher certifications, catering to diverse local demographic requirements.
The shelf life is 24 months from the production date when stored in its original unopened packaging. For the humid tropical climate of Sri Lanka, we recommend storing the bags in a dry, well-ventilated warehouse, ideally below 25°C and with relative humidity under 60%, to prevent lumping.
We use advanced industrial washing and membrane filtration to reduce total glycoalkaloids (TGA) to less than 100 ppm, which is well below standard safety regulations. This ensures no bitter off-notes or safety issues in the final food formulations.
Our standard MOQ for commercial orders is 1,000 kg. However, we support smaller trial shipments for prototype validation. The typical lead time from our advanced manufacturing facility to Colombo Port is 15 to 25 days, depending on shipping schedules.
Yes, our potato protein isolate remains highly soluble across a broad pH range of 3.0 to 7.0, showing minimal precipitation at the isoelectric point. This makes it an ideal fit for acidic ready-to-drink (RTD) beverages, energy drinks, and fruit juices.
We provide a complete documentation package, including the Bill of Lading, Certificate of Analysis (COA), Phytosanitary Certificate, Health Certificate, Halal Certificate, Packing List, and Commercial Invoice, ensuring seamless customs clearance at Sri Lankan ports.
Yes, we provide customization options. Our R&D team can adjust properties like bulk density, solubility index, and particle size distribution (e.g., superfine milling for beverage premixes) to meet your specific processing needs.
