For Omega 3 Quality, Go by the Numbers
The new voluntary monograph for omega 3 EPA and DHA adopted by the CRN working group on omega 3 fatty acids establishes new, more stringent quality standards for these ingredients.
The new quality standards are:
Measures of oxidation:
Peroxide value (PV): Maximum 5 meq/kg
Anisidine value (AV): Maximum 20
TOTOX: Maximum 26 (calculated as (2 x PV) + AV)
Quantity of omega 3 fatty acids:
Acid value: Maximum 3 KOH/g
Quantity of EPA and DHA expressed on a weight/weight basis (mg/g)
Purity:
Maximum 2 pg/g dioxins (PCDDs, PCDFs)
PCBs less than 0.09 mg/kg (ppm)
Lead, cadmium, mercury, arsenic: each less than 0.1 mg/kg (ppm)
