INTERPRETATION
What “good” VCO looks like (key specs)
- Moisture & volatile matter: ≤ 0.20% (too much moisture → rancidity/microbial risk). Scribd
- Free Fatty Acids (as lauric acid): ≤ 0.20% (low FFA = fresh, well-handled oil). Scribd+1
- Peroxide Value: ≤ 3.0 meq O₂/kg (higher means oxidation already started). Scribd+1
- Additives: None permitted in virgin/cold-pressed oils. FAOHome
- Sensory: Colorless/very pale, sediment-free, fresh coconut aroma, no rancid notes. spsissuances.da.gov.ph
Those limits align with the Philippine National Standard PNS/BAFPS 22:2007 and APCC VCO Standard used widely in trade.
If anything is borderline/high
- Moisture high → improve final drying/polishing filtration; check storage drums for condensation.
- FFA high → shorten time from extraction to oil separation; keep temps low; avoid water contact; use food-grade, dry containers.
- PV high → reduce air/light/heat exposure; use nitrogen blanketing if possible; rotate stock (FIFO).
Quick verdict
- Moisture (gravimetric): 0.09%
- Passes PNS/BAFPS 22:2007 guidance (commonly ≤ 0.20%). It also passes the stricter APCC guide (≤ 0.15%). The 0.09% is ~45% of the 0.20% limit and ~60% of the 0.15% limit. spsissuances.da.gov.phCoconut Community
- Peroxide Value (titrimetric): 0.34 meq O₂/kg
- Excellent—well below the 3.0 meq/kg ceiling used in PNS/APCC for VCO quality. ~11% of the limit, indicating minimal primary oxidation. Coconut Communityphiljournalsci.dost.gov.ph
What this means
- Freshness & stability: Low moisture + very low PV = low rancidity risk and better shelf life if you keep the oil away from heat, light, and air.
- Methods used: Gravimetric moisture and titrimetric PV are standard methods used in oil QC; they’re acceptable for trade compliance with VCO standards. (Some labs also run Karl Fischer for moisture.)
