Development of mixed fruit leather from guava (Psidium guajava) and dragon fruit (Hylocereus undatus)

Abstract

Fruit leather can be classified as a snack which is suitable for all, especially children. Fruits leathers are not only colourful and flavourful components, but they also serve as a source of energy, vitamin, and other nutrients. The objective of this study was to develop new fruit leather from guava mix with dragon fruit. There were five formulation of fruit leather which were formulation A (100 % guava purees), B (10 % dragon fruit puree, 90 % guava puree), C (30 % dragon fruit puree, 70 % guava puree), D (50 % dragon fruit puree, 50 % guava puree), and E (75 % dragon fruit puree, 25 % guava puree).Three analysis which were chemical analysis, physical analysis, and sensory evaluation were carried out. The entire tests were analyzed by SAS programmed to determine the Analysis of Variance (ANOV A) and Duncan's Multiple Range Test (DMRT). For chemical analysis, there were no significance different (p<0.05) for moisture, ash, protein, fat, and carbohydrate content.
