Client: GreenGourmet GmbH (Germany) A leading European high-end plant-based food enterprise specializing in Michelin-grade plant-based seafood (artificial sea cucumber / artificial lobster), organic low-fat plant-based mousse and premium ready-to-eat meat analogues. Its products are sold in high-end supermarkets and Michelin-starred restaurants across Germany, Austria and Switzerland, complying with EU E418, FCC, EU Organic and ISO 22000 standards. The client requires curdlan with high gel strength, extreme temperature resistance, low water syneresis and consistent batch quality, categorizing it as a highly technology-sensitive mid-to-high-end client.
In March 2026, the client purchased 50 tons of food-grade curdlan (minimum gel strength ≥1000 g/cm²) from China for mass production of premium artificial sea cucumber. Within one week of production launch, three critical technical failures emerged: gel cracking, severe water syneresis after freeze-thaw cycles and uneven texture, pushing defect rates above 30%. Facing production shutdown, order breach and brand reputation damage, the client urgently entrusted HiSiaddi to identify root causes, optimize formulations and resolve manufacturing technical issues within 7 days.
1.
Gel cracking with insufficient elasticity post sterilization After high-temperature sterilization at 121°C for 30 min, artificial sea cucumber edges cracked and internal structures loosened, breaking easily under light pressure, failing to meet Michelin’s "springy, firm and shatter-resistant" texture standard. Client internal testing revealed actual gel strength of only 750 g/cm², far below the purchased standard of ≥1000 g/cm², indicating loose gel network structures.
2.
3.
Severe water syneresis after freeze-thaw cycles: water separation rate exceeding 15% after 5 cycles After 48 hours of freezing at -18°C followed by thawing at 25°C, five repeated cycles caused excessive surface water separation, texture softening and volume shrinkage, severely degrading product appearance and mouthfeel and violating European high-end vegetarian standards for freeze-thaw stability with zero syneresis.
4.
5.
Uneven texture with visible graininess White tiny particles formed on both the surface and interior of finished products, creating a coarse mouthfeel with inconsistent hardness across cross-sections, failing to meet premium vegetarian requirements for smooth, particle-free textures.
6.
1.
Incompatible raw material performance The ordinary industrial-grade curdlan initially sourced only reached 93% purity with 0.45% ash content. Impurities including heterologous proteins and oligosaccharides disrupted gel network continuity, resulting in low gel strength and brittle textures. Uneven molecular weight distribution (5×10⁵–2×10⁶ Da) with excessive low-molecular-weight fractions weakened gel structures and freeze-thaw resistance.
2.
3.
Flawed formulation design (single colloid & unbalanced ratios) The client’s original formulation only incorporated 2.5% curdlan without colloid compounding, leading to low gel toughness and poor shear resistance, causing breakage during high-temperature sterilization. Improper pH control at pH 6.2 fell within curdlan’s low gel strength range (pH 5.5–6.5), drastically reducing structural rigidity. Insufficient calcium ion content (0.02%) failed to crosslink polysaccharide molecules, destabilizing gel networks and amplifying water separation.

Erroneous manufacturing process operations
6.
· Improper pretreatment: Direct addition of curdlan powder to room-temperature water caused uneven dispersion and agglomeration, forming hard core particles with wet outer layers that created grainy textures.
· Insufficient heating temperature: Product core temperature only hit 72°C during sterilization, below the mandatory 80°C threshold for complete curdlan gelation, yielding unstable structures prone to water release.
· Excessively rapid cooling: Immediate ice-water cooling post sterilization generated internal stress from uneven contraction of gel interiors and exteriors, triggering cracking.
The low-grade industrial raw material was immediately replaced with customized CG-800 curdlan supplied by Jiangsu Caiwei Bio, with core specifications as follows:
· Purity: 99.6%, ash content: 0.08%, free of heterologous proteins
· Gel strength: 1250 g/cm² (far exceeding client standards)
· Uniform molecular weight range: 8×10⁵–1.5×10⁶ Da
· Particle size: 90 mesh (ultra-fine, easy dispersion)
Collaborating with Jiangnan University Food Laboratory, three rounds of formulation iteration were completed within 3 days. Optimized base formulation for artificial sea cucumber:
1. Core colloid compounding (7:3 ratio): 2.0% curdlan + 0.6% carrageenan, lifting gel strength by 83% and drastically improving toughness and freeze-thaw resistance.
2. Precise pH adjustment: 0.2% citric acid + 0.1% sodium carbonate to stabilize system pH at 7.2, curdlan’s optimal gel strength range.
3. Calcium ion reinforcement: 0.15% calcium chloride to boost polysaccharide crosslinking, stabilize gel networks and reduce water separation rates.
4. Moisturizing system enhancement: 3.0% glycerol + 2.0% maltitol to elevate water retention, capping post 5-cycle freeze-thaw water separation at under 3%.
1. Dry powder premixing: Uniformly blend curdlan, carrageenan, salt and sugar to avoid agglomeration.
2. High-speed dispersion in ice water: Mix with 0–5°C ice water under high-speed chopping at 1200 rpm for 5 minutes to form homogeneous suspensions free of solid particles.
3. Optional alkaline dissolution neutralization: Adjust pH to 12, stir for 15 minutes then neutralize back to neutrality for an additional 15% gel strength gain.
1. Slow temperature ramp at 1°C per minute to prevent localized overheating.
2. Maintain core temperature at 83°C for 20 minutes to guarantee full gelation.
3. Segmented cooling protocol (60°C → 40°C → 25°C, 30 minutes per stage) to eliminate internal stress and prevent cracking.
1. Maintain 10–15°C low-temperature operating conditions throughout production to avoid premature gelation.
2. Deploy high-shear emulsifiers to boost dispersion uniformity and eliminate graininess.
50 kg trial production using optimized formulations and processes underwent third-party testing with the following results:
· Gel strength: 1280 g/cm²
· Water separation rate after 5 freeze-thaw cycles: 2.8%
· Texture: Smooth, particle-free, springy and firm Client laboratory full testing confirmed sample eligibility.
For mass production implementation, HiSiaddi dispatched technical specialists to the German manufacturing plant for 3 days of on-site guidance, training operators, calibrating equipment parameters and supervising full production lines to resolve mass-production technical details. Defect rates plummeted from 30% to 0.5%, restoring full production capacity.
