ABSTRACT: The use of synthetic
food colorants is increasing because of its advantages. However, it is found
that not all food colorants which are sold in the market are safe to be
consumed. The purpose of this research was to identify synthetic food colorant
samples which are sold in market and to find out whether they contain safe food
colorants or not. Extraction did not need to be done on samples. Analysis was done
using color reaction and paper chromatography. Densitometry was done to support
the identification result. The result of this research showed that 10 out of 31
samples that were tested contain synthetic food colorants that must not be used
for food. The ten samples were seven red colorants (three samples containing
Merah K4, the two others containing Rhodamine B, and two samples containing
Scarlet GN), one orange colorant (containing Orange G), one yellow colorant
(containing Metanil Yellow) and one chocolate colorant (containing Chocolate
Brown FB).
Key words: colour reaction, densitometry, paper chromatography,
