Aromatics of a C15C30 mineral oil fraction, the “batching oil” used for producing jute fabrics, were analyzed for estimating the toxicity of oil transferred from jute bags to foods. Group‐type pre‐separation according to ring systems occurred on a LC NH2 column with pentane and small additions of methanol as eluent. LC fractions were characterized by LC‐GC‐MS and quantitated by LC‐GC‐FID. The oil contained 23% aromatics and 1% “polars”; some 99.5% of the aromatics were alkylated.
