Identification of Acidic and Basic Dyes in Different Candies

Synthetic food colors are added in different food items. These colors directly affect consumer food selection and acceptance. Synthetic colors on the basis of solubility are categorized into acidic (permitted) and basic (non-permitted). The present study was conducted to check the synthetic color present in branded and unbranded candies it is either acidic or basic. For this purpose, 15 samples were collected and analyzed in Food Science and Technology Laboratory of the University of Haripur. It was observed that all tested samples contain acidic colors when 20 grams of grinded sample and 5 ml of acetic acidic were taken. The present of acidic synthetic colors may lead to the conclusion that these tested candies can be used at permissible concentrations of dye without any risk to human health. The use of basic colors may cause human health affect from mild to severe whereas permitted acidic colors are safe to use if use within permitted range.
