Client: VeggiLux NV (Belgium) A leading European high-end plant-based food enterprise specializing in organic plant-based seafood (artificial abalone / artificial sea cucumber), premium low-fat plant-based cheese, and Michelin-grade meat analogues. Its products are supplied to high-end supermarkets and Michelin-starred restaurants across Belgium, the Netherlands and Luxembourg. The company complies with EU standards including E418, FCC, ISO 22000 and EU Organic certification. It imposes stringent requirements on curdlan: high purity, customized gel strength, low ash content, zero pesticide residues and consistent batch quality, making it a technology-oriented mid-to-high-end client.
In January 2026, the client made its first curdlan procurement from China for manufacturing premium organic artificial abalone. Its core requirements were customized gel strength (1200–1300 g/cm²), ash content ≤0.1%, particle size 80–100 mesh and organic certification. However, after liaising with three manufacturers, the project was nearly suspended due to four major hurdles: unmet technical standards, weak customization capacity, long delivery lead times and incomplete certifications. The client urgently entrusted HiSiaddi to source customized production capacity, resolve technical bottlenecks and deliver samples and mass-produced goods within 2 weeks.
1. Gel strength: 1200–1300 g/cm² (measured after heating at 80°C then cooling, far exceeding the standard industrial grade of 800 g/cm²)
2. Purity: ≥99.5%, ash content ≤0.1% (ordinary products range from 0.3% to 0.5%)
3. Particle size: 80–100 mesh (fine powder with good dispersibility to avoid grainy surfaces on artificial abalone)
4. Certifications: EU Organic, E418, FCC
5. Application compatibility: No loss of elasticity, melting or water separation after high-temperature sterilization at 121°C for 30 min for artificial abalone; gel strength retention rate ≥90% after 5 freeze-thaw cycles (-18°C freezing & room-temperature thawing)
1. High technical barriers: Conventional manufacturers can only produce standard grades with gel strength of 800–1000 g/cm², failing to stably reach 1200+ g/cm², and lack mature low-ash production processes.
2. Limited customization capacity: Most factories prioritize standardized mass production and are unwilling to adjust production lines for small annual orders of 30 tons, extending customization cycles for particle size and gel strength to over one month.
3. Certification gaps: Most manufacturers only hold China’s GB 2760 certification, lacking EU Organic and E418 credentials, which blocks access to high-end European markets.
4. Unstable delivery: High-end customized production capacity is tight, with scheduling lead times of 45–60 days, conflicting with the client’s 25-day delivery schedule aligned with its production plan.
Filtering out mass-production-focused manufacturers based on customization capacity, technical reserves, EU certifications and high-end client track records, HiSiaddi finalized Jiangsu Caiwei Bio as the partner. A leader in high-purity customized production, it operates a joint laboratory with Jiangnan University and boasts mature technologies for high-strength gel and low-ash curdlan manufacturing. It holds full EU Organic, E418 and FCC certifications and has previously supplied customized high-strength curdlan to top European plant-based brands, fully meeting all the client’s mandatory specifications.
1. Fermentation formula adjustment: Precisely regulate carbon-nitrogen ratio (replacing corn starch with controlled glucose dosage) and magnesium/manganese trace element proportions to enhance strain gel-producing performance.
2. Purification upgrade: Adopt membrane separation plus secondary low-temperature spray drying to remove impurities and increase polysaccharide polymerization degree, stabilizing gel strength at the median value of 1250 g/cm² within the required range.
1. Add activated carbon deep decolorization and ion exchange resin metal removal procedures to eliminate calcium, magnesium, iron and other ions.
2. Use purified water with resistivity ≥18.2 MΩ·cm for all production steps, delivering a final ash content of 0.08%, exceeding the client’s requirement.
Adjust spray drying atomization pressure and graded screening; 95% of particles fall within 80–100 mesh. The ultra-fine powder achieves a 30% improvement in cold water dispersibility, eliminating grainy textures on artificial abalone surfaces.
1. Small-batch trial production (5 kg): Caiwei Bio completed formula adjustment and produced customized samples in 3 days.
2. Third-party testing via TÜV Rheinland: Test results showed gel strength 1250 g/cm², purity 99.6%, ash content 0.08%, particle size 90 mesh and non-detectable heavy metals, fully meeting all specifications.
3. Client application trials: Laboratories in Belgium manufactured artificial abalone samples. After 30 min sterilization at 121°C, products retained full elasticity with no melting or water separation; gel strength remained 92% after 5 freeze-thaw cycles, fully satisfying texture and stability requirements for high-end artificial abalone. The client confirmed sample approval.
1. Capacity reservation: Coordinate priority production scheduling at Caiwei Bio, securing an annual customized capacity of 100 tons to guarantee stable supply for the client’s 30-ton annual order.
2. Production quality control: All manufacturing takes place in a Class 100,000 clean workshop. Each batch undergoes triple testing (in-house inspection + third-party testing + client random sampling), with full COA, organic certificates and E418 statements issued.
3. Custom packaging: Food-grade aluminum foil bags (1 kg per bag) inside moisture-proof cartons, printed with EU Organic logos, E418 codes, batch numbers and traceability codes to comply with EU labeling regulations.
4. Logistics delivery: Cold-chain transportation via China-Europe Railway Express, arriving at the client’s Belgian warehouse in 25 days with intact packaging, no moisture damage and complete documentation.
1.
Customized products fully compatible with high-end applications After bulk delivery, the client launched mass production of artificial abalone. The products delivered Michelin-standard elasticity, texture and stability without quality degradation post sterilization or freeze-thaw treatment. The goods entered premium supermarkets and Michelin restaurants across Belgium and the Netherlands, lifting product premium margins by 25% with zero downstream complaints after full inspection by brand partners.

· A 30-ton annual long-term framework agreement was signed to lock in Caiwei Bio’s customized production capacity.
· The client appointed HiSiaddi as its exclusive China-based customized procurement consultant for future high-strength, low-ash and special particle-size curdlan customization.
· Additional customization requests for curdlan used in premium plant-based cheese were submitted, entrusting HiSiaddi to develop acid-resistant (pH 4.0) and high water-retention formulations.
1. Word-of-mouth market expansion to penetrate high-end European markets The client recommended the customized curdlan to peers in the Netherlands and Switzerland, driving three other top European plant-based food enterprises to source customized curdlan through HiSiaddi. This formed a high-end customized client cluster, enabling Chinese high-end customized curdlan products to enter core European premium markets.
Demand for curdlan among mid-to-high-end European plant-based food clients has evolved from basic thickening agents to core functional raw materials requiring high gel strength, low impurity levels, full customization and complete regulatory compliance. Primary pain points include high technical barriers, scarce customized production capacity, incomplete certification portfolios and lengthy delivery cycles. Conventional manufacturers are constrained by technical limitations and production capacity, unable to satisfy high-end customization demands.
HiSiaddi’s core competitive advantage lies in accurate insight into high-end market demands + screening of top-tier customized manufacturers + joint technical R&D + end-to-end delivery guarantee. The team possesses dual expertise: in EU high-end market technical standards and compliance rules, as well as Chinese leading manufacturers’ customization capabilities and flexible production capacity. It rapidly integrates industrial resources, resolves technical bottlenecks and shortens delivery lead times, fulfilling high-end customization requirements for mid-to-high-end clients, stabilizing product quality and supply chains, and acting as a core bridge connecting Chinese bio-based customized manufacturers to the premium green food market in Europe.
