Abstract
The use of colors in food is associated with its quality and is long term practice. The use of synthetic dyes in recent years has been increased significantly. Near about 3000 dyes are said to be in the use as food colorants at world level. In general, azo dyes are the most common dyes used in food colors. It has been reported that azo group can be chemically reacted, or as itself can be a basis of carcinogenic amines (formed by the chemical reaction of azo group) determination of banned azo dyes in consumer’s food is therefore of utmost concern. This study describes a novel diffuse reflectance-Fourier transform infrared spectroscopic (DRS-FTIR) method for simultaneously determining the qualitative and quantitative presence of three food additive viz, tartrazine, carmoisine & Vanillin in commercially available food stuffs. The FTIR spectral studies of food additives were taken between 4000-400 cm-1 and characteristic peaks of all three analytes were selected for identification. The absorbance and peak area were determined which shows excellent linearity for concentration range upto 100 ug mL-1. The statistical parameters such as limit of detection and limit of quantification were also determined. The method was successfully applied to food and beverage samples and good recoveries were obtained.
