There were significant differences(po0.05)in the fixed and volatile acidity of the samples studied. The fixed acidity of the samples ranged from(2.20–5.60) withsample443(20%banana: 40%pineapple :40%apple)having the highest fixed acidity while sample819 (40%banana:40%pineapple:20%apple) recorded the least fixed acidity.Sample443 (20%banana:40%pineapple: 40% apple) recorded the highest volatile acidity of(36.33)and was significantly higher(po0.05)than other samples which had (30.77and26.03) respectively for sample819(40%banana:40% pineapple:20%apple) and314 (60%banana:20%pineapple: 20% apple).The high content of the volatile acid sin the samples were responsible for the flavor development. The fixed acid content of the sample has been in dication to aid in the storage stability of the samples(http://www.google.com).
