Abstract
Abstract Metanil yellow, manufactured for textile and other purposes. IS frequently used to colour foodstuffs. A simple and sensitive spectrophotometric method has been developed for the estimation of metanil yellow in foodstuffs and biological tissues. The recovery of metanil yellow is 86.5 % to 96.9 %. Curcumin, bile salts, riboflavin etc. do not interfere. The method is reliable, rapid and the lowest limit of detection is 1 μg. This method can also be applied as a simple colorimetric procedure by reading the colour value in any standard colorimeter using a green filter.
