Abstract:
Colors are added to food to enhance its flavor and texture. They are important food additives as they are concerned with the taste and perception of food.
According to FSSAI, food colors should be added within permissible limits. Hence, various analytical techniques should identify, isolate, and quantify it. UV- Visible spectrophotometer is a simple and accurate method to determine the colors in food products and compare the results by plotting a calibration curve obtained by the different concentrations of standard food colors.
