For commercial oil millers, two numbers matter above all: oil content percentage and shelling percentage. Together they determine how much usable oil you extract from every quintal purchased.
The Two Key Metrics
Oil Content (%)
Percentage of oil extractable from the kernel on a dry-weight basis. Ranges from ~46% in local varieties to 53.9% in Pragati Super 32.
Shelling Percentage (%)
Ratio of kernel weight to pod weight. Higher shelling means more usable kernel from the same weight of pods purchased. Super 20's 73.4% is among the highest of any commercial variety.
Variety Comparison for Oil Millers
| Variety | Oil Content | Shelling % | Rating |
|---|---|---|---|
| Pragati Super 32 | 53.9% | 68.5% | ⭐⭐⭐⭐⭐ |
| Pragati Super 4 | 53% | 67% | ⭐⭐⭐⭐⭐ |
| Pragati Super 24 | 50.8% | 70–72% | ⭐⭐⭐⭐ |
| Pragati Super 20 | 49–51% | 73.4% | ⭐⭐⭐⭐ |
| Pragati Super 37 | ~48% | Standard | ⭐⭐⭐ |
Recommendation: Prioritise Super 32 for maximum oil per quintal. Blend with Super 20 if shelling efficiency is your bottleneck.
Practical Calculation
Per 100 kg of Super 32 pods — at 68.5% shelling, 53.9% oil, 85% expeller efficiency — you extract ~31.4 kg oil. Versus a local variety at 46% oil: ~26.6 kg. That is 4.8 kg more oil per 100 kg pods, worth ~₹672 extra revenue per quintal at ₹140/kg oil.
