Abstract

A titrimetric method for determining citral was developed; it is based on the quantitative reaction of citral with semicarbazide hydrochloride to form a semicarbazone. The semicarbazone is removed and the excess unreacted semicarbazide is determined iodometrically using chloramine-T reagent. 2 mol chloramine-T are required/mol semicarbazide. The method was applied to the detn. of total aldehyde in citrus oils (expressed as citral in lemon and lime and as decanal in orange). Data are tabulated in detail. The present method can be used in the routine quality evaluation of citrus oils, and the sample required is in the range 0.5-1.0 g.
