Plant-Starch Softgel & Dual-Cavity Encapsulation Glossary
Quantitative definitions, rheological benchmarks, and test methods for modified plant-starch softgel shells, twist-off cosmetic capsules, and rotary die encapsulation lines.
| Engineering Term | Target Parameter / Benchmark | Technical Definition & B2B Procurement Significance |
|---|---|---|
| Modified Plant-Starch Matrix (Compound Thickener) | 88–95°C Gel Cooking; 18,000–28,000 mPa·s | Non-animal hydrocolloid-starch blend licensed under SC20344011403743 & Halal HCS-DJS60818 (Compound Thickener). Replaces bovine/porcine gelatin in rotary die softgels. |
| Aldehyde Cross-Linking (Pellicle Resistance) | 0% Protein Cross-Linking (24-Month Accelerated) | Animal gelatin cross-links when exposed to trace aldehydes in oxidized oils or botanical extracts, forming an insoluble membrane. Plant-starch lacks protein amino groups, remaining soluble. |
| Tropical Anti-Sticking Threshold | 45°C – 50°C at 75% RH (48h Chamber Test) | Temperature at which softgels resist agglomeration and oil weeping during non-reefer sea freight to ASEAN, Middle East, and Latin America (gelatin softens at 35–38°C). |
| Seam Fusion Ratio (Rotary Die) | ≥ 45% of Wet Ribbon Thickness | Microscopic cross-section ratio of the thermally welded capsule seam relative to shell wall thickness, critical for zero-leakage air/sea transport. |
| Fill Water Activity (Aw) Limit | Aw ≤ 0.45 (Free Water < 3.0%) | Maximum free water activity permitted in cosmetic serums or oil suspensions to prevent plasticizer migration or shell softening. |
| Twist-Off Neck Torque Balance | 1.0 – 2.0 Turns Hand Twist; Burst ≥ 50 N | Die-roll neck land calibration ensuring effortless consumer twist-open while surviving 50 N compression in blister or jar transit. |
| Dual-Cavity Rotary Die Encapsulation | ±0.02 mm Ribbon Casting Tolerance | Precision encapsulation architecture pairing PID-controlled spreader boxes and wedge heaters specifically tuned for higher-viscosity plant-starch ribbons. |
