Having obtained done banana peel flour donut -making flour substitute banana peel . The use of banana peel flour with different concentrations turned out to affect the organoleptic properties of the donut . Of hedonic organoleptic test , the results of the average value of the ratio between wheat flour with flour banana skin that gives the best results for color , aroma , and flavor that is a donut with banana peel flour ratio of 0 % to 100 % wheat flour and donuts with banana peel flour ratio 10 % with 90 % wheat flour , but the texture will be best results are donuts of banana peels can be made by substituting wheat flour with flour banana skin at 10 %.
