Apple pomace is a valuable waste from the apple juice industry with high level of poly phenols and also phytate-free dietary fiber. This research was done to optimize and compare the physical properties of new gluten-free cake based on whole replacement of wheat flour with apple pomace powder using starch and xanthan gum by Mixture Design. The results of chemical analysis of apple pomace flour showed 10% moisture, 1.28% ash, 1.68% fat, 1.25% protein, 56% fiber and 9.62 mg gallic acid/g phenolic compounds. There was a significant difference in the texture of optimized apple pomace cakes in comparison to rice and wheat cakes as control and black samples. The hardness of the wheat flour sample was less than the gluten-free samples. Based on the results of the sensory evaluation, the cake containing apple pomace powder had the highest score in terms of overall acceptance.
