Samples were analyzed for color determination. After color extraction by acetic acid, ammonia and wool, color identification done by TLC. Results: from samples of pistachio, Indian walnut, pumpkin seed, sunflower seed and Japanese seed surveyed, 35.7%, 39.3%, 27.2% and 21.4%, contained artificial colors, respectively. From 163 ice cream samples examined, 57 samples (34.97%) contained artificial color and 106 samples (65.03) had natural color.
