Abstract

Coloured plastics containers are increasingy used for storage and sale of edible oils; leaching of colorants into the oils may occur. Investigations were conducted on detection, identification and detemination of colorants in oils, and to assess migration of colorants from plastics containers into oils. Trials were conducted using the sandwich filter paper method, UV/Visible spectroscopy, TLC and FTIR spectroscopy. The main colorants identified and quantified were Permanent Yellow GG (CI 21100) and Permanent Orange G (CI 21110). Max concn. of colorant leached was 2 p.p.m. after 10 days in n-heptane and 30 days in decolorized coconut oil, for 5 l containers. Colorant migration was similar for different oils.
