| Abstract: | Allura red is afood additive color which is approved to use in china in 1990. The method for detremination of Allura red in beverage,candy, cake and icecream was described. Allura red showed λmax 500nm. The moving phases for separation of Allura red and ponceau 4R, Amaranth, Sunset yellow, tartrazine, brilliant blue were:(1) butanone +acetone+water +ammonium hydroxide(7+3+3+0.5) (2)butanol+ethyl alcohol,absolute+1%ammonium hydroxide(6+ 2 + 3),(3)2.5%sodium citrate+ammonium hydroxide + ethylalcohol (8+ 1 +2) The recovery rates were 91. 76%～95. 83% in candy, 90. 44%～92. 73%in beverage,83. 48%～84. 90% in cake product,72.5～86. 7% in icecream.
