The results of the physico-chemical composition and vitamin C composition of mixed fruit leather produced from banana–pineapple–apple were shown in Table2. Sample 819 (40% banana:40%pineapple:20%apple) recorded the highest total soluble solids(TSS)(20.07)and was significantly different (po0.05) fromsample314(60%banana:20% pineapple:20%apple)and sample443(20%banana:40% pineapple:40%apple)which recorded(10.03gand9.13g) respectively. The soluble solids content is one of the most important quality parameters in processing. 55% of soluble solids content are sugars, glucose and fructose and their amount and proportions in fluency the organoleptic qualities of fruit and fruit leathers. The TSS of this study was very high which could be due to moisture loss during drying and high TSS is desirable yield higher recovery of processed products (Adedeji etal.,2006).The high TSS could also be due to the sugar sprinkle on the leather samples prior to packaging. The total titratable acidity showed that all the samples were significantly different (po0.05) from one another with sample 819 (40%banana:40%pineapple:20%apple)recording the highest TTA(0.42g/100g)while sample 314had the least with (0.30g/100g).
