Sesame oil press FAQ: route, yield, antioxidants, packaging
Sesame hard data: seed oil 45-55%, moisture 5-7%, protein 18-25%, 1000-seed weight 2.5-4 g, impurities <0.1%. Roasted 180-200°C × 15-25 min → press 80-100°C → 200-325 ton → yield 40-50% → smoke point 177°C. Cold ≤60°C → 355-500 ton → yield 35-42%. Sesamol + sesamin 0.4-1.0% → shelf life 12-24 months in dark glass 100-250 ml + N₂ headspace O₂ <2%.
Cold route data
≤60°C end-to-end → 355-500 ton hydraulic → 60-90 min cycle → yield 35-42% → 1-5 μm bag filter → light golden, premium salad/cosmetic. ≤40°C + 0.22 μm sterile for cosmetic-grade.
Roasted route data
Drum/wok roaster 180-200°C × 15-25 min → 200-325 ton press at 80-100°C → 40-60 min cycle → yield 40-50% → 200-300 mesh filter → strong-aroma 小磨香油, smoke point 177°C.
Packaging and shelf life
Dark glass 100-250 ml, N₂ headspace O₂ <2%, FFA <0.5%, peroxide <5 meq O₂/kg, sesamol/sesamin 0.4-1.0% → 12-24 months at ambient without refrigeration.
Decision themes
Three things sesame inquiries always need to answer
Cleaning to <0.1% impurities
1000-seed weight 2.5-4 g makes contamination disproportionately disruptive. Vibrating screen + air aspirator + magnetic separator + destoner. Stones <0.05%, foreign matter <0.1%.
Route by product, not by marketing
Roasted (180-200°C) for Asian flavor oil / 小磨香油. Cold (≤60°C) for Western premium salad and cosmetic. Same press family can serve both with route changeover.
Filtration depth = compliance target
200-300 mesh = bulk/crude. 1-5 μm bag = retail clarity. 0.22 μm sterile = cosmetic-grade (GMPC / ISO 22716). FFA <0.3% = infant grade.
Hard data references
Numbers a serious sesame quote already names
- Seed: oil 45-55%, moisture 5-7%, protein 18-25%, 1000-seed weight 2.5-4 g, impurities <0.1%.
- Roasted yield 40-50% on 200-325 ton at 80-100°C, 80-100 kg/barrel, 40-60 min/cycle.
- Cold yield 35-42% on 355-500 ton at ≤60°C, 80-100 kg/barrel, 60-90 min/cycle.
- Smoke point: unrefined 177°C, refined 232°C. FFA <0.5%, peroxide <5 meq O₂/kg.
- Sesamol + sesamin 0.4-1.0% (sesamol forms during roasting from sesamolin) → 12-24 month shelf life with N₂ packaging.
