We're There Every Step of The Way
Raw Material Selection
1.Impurity≤1%
2.Oil content≥10%
3.Acid value≤3mg KOH/g
4.Moisture≤12%
The production begins with rigorous selection of sea buckthorn seeds. Seeds must be plump, mold-free, and meet stringent quality criteria including ≤1% impurities and ≥10% oil content[^5]. Raw materials undergo sensory and lab tests to ensure absence of off-odors and compliance with GB 19641 standards
Crushing
1.Crushing cycles: 3-4
2.Particle size≤0.45mm
Seeds undergo 3-4 crushing cycles to achieve uniform particle size (≤0.45mm), optimizing subsequent CO₂ penetration during extraction
Loading Extraction Vessels
1.80kg/vessel
2.Packing density 0.5g/cm³
Crushed seeds are loaded into extraction vessels at 80kg per batch with controlled packing density to ensure uniform supercritical fluid flow
Supercritical CO₂ Extraction
1.Pressure:30MPa
2.Temperature:50±2℃
3.Duration:2.5h
CO₂ extraction occurs at 30MPa/50°C for 2.5 hours with 60% concentration setting. This preserves heat-sensitive compounds like vitamin E (≥140mg/100g)
Dehydration & Purification
1.Moisture≤0.2%
2.Centrifugation cycles:2-4
3.Duration:2.5h
Centrifugation (2-4 cycles) removes water to ≤0.2% content, meeting standards
Quality Testing
1.Acid value≤10mg KOH/g
2.Peroxide≤0.25g/100g
Batch testing verifies 18+ parameters including fatty acid profile (α-linolenic acid 23-31%) and contaminants (Pb≤0.1mg/kg)
Packaging & Storage
1.Storage temp:5-8℃
Oil is packed in food-grade stainless steel drums under nitrogen. Cold storage (5-8°C) maintains stability.
