Abstract
The development, by collaborative study, of a standardised method for the direct determination of 2-thiobarbituric acid value in oils, fats and derivatives is described. Fats and oils are reacted, without previous iolation of volatiles, with 2-thiobarbituric acid, and the absorbancy of red-coloured condensation products is measured at 530 nm.Keywords
