Determination of Propylene Oxide Residue in Food Wrappings and Containers

Abstract

Residues of propylene oxide in food wrappings and containers fumigated with its vapor were determined by means of gas chromatographic method.
Results are shown in the Table 1.
The residue was probably caused by being dissolved in the various plasticizers contained in plastic food wrapPings and containers or being absorbed on the surface of wood materials.
