Formulation 3 has the lowest microbial growth with 5.0 x 105 cfu/ml after 28 days of storage. The sensory evaluation resulted in the acceptance of Formulation 3 is the highest with an overall acceptability score of 8.6.

摘要

Aloe vera and lime (Citrus aurantifolia) nutritional contents are known as highly beneficial plants that contain various functional compounds. This study is aimed to formulate aloe vera – lime (AV-L) juice and characterizes the physicochemical of the fruit juice mixture. Five samples were prepared which were reference sample (control) from commercialized aloe vera drink, Formulation 1 (80% aloe vera + 20% lime), Formulation 2 (75% aloe vera + 25% lime), Formulation 3 (70% aloe vera + 30% lime) and Formulation 4 (65% aloe vera + 35% lime). Physicochemical properties, microbiological analysis and sensory of the formulations were determined. Formulation 3 resulted in the highest pH value at the end storage with pH 2.13. Titratable acidity analysis shows that Formulation 4 has the highest acidity with 1.82%, total soluble solids (TSS) of 13.4oBrix. Color analysis shows that Formulation 3 has high value of L* (37.54), a* (−0.73) and b* (2.93) at day 28 which gives the juice darker, greener and yellower color than the initial. Formulation 3 shows the highest antioxidant, total phenolic content and total flavonoid content of 75.32%, 1.153% mgGAE/g, and 1.044% mgQE/g respectively. Formulation 3 has the lowest microbial growth with 5.0 x 105 cfu/ml after 28 days of storage. The sensory evaluation resulted in the acceptance of Formulation 3 is the highest with an overall acceptability score of 8.6. Thus, this study has concluded that the addition of lime in aloe vera can be improvised to produce a longer shelf life fruit juice drink.
