ISO 4735:2002 specifies a method for the determination of the CD value of the essential oils of Citrus by ultraviolet spectrometric analysis.
Abstract
Overview
ISO 4735:2002 specifies a laboratory method for determining the CD value of essential oils of Citrus using . The standard defines how to prepare an ethanolic solution of a citrus oil, record its UV absorbance curve in the range, and calculate the CD value (expressed in absorbance units per gram). The method is intended for quality control, characterization and specification of citrus essential oils.
