Mineral oil material in canned foods

Abstract
Mineral oil material was determined in canned foods by on‐line LC‐LC‐GC‐FID. In the edible oil phase of 90 samples of sea foods, concentrations were mostly around 100 mg/kg, but reached 820 mg/kg. The predominant source of this mineral oil material was lubricating oil used for can manufacturing. Mineral oil contamination of the fish was usually a minor source, but cannot be neglected.
