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.
