Abstract

Concern on different food colours has a rising tendency in the last decades. Many times the labelled ingredients of a food product don’t reflect the real composition. To expose products adulterated by synthetic colorants or to check non-packed foods (like ice cream, fruit drinks sold on the streets) fast and cheap methods are needed. Quick and in situ determination of the colouring agents can be achieved with high sensitivity and reproducibility by using the presented test method based on visual and/or optical characterisation of the cellophane test strip. The selectivity of cellophane to synthetic dyes is used to distinguish natural and synthetic food colours in beverages and foods.
