Development of Bioactive Plantain Stem Juice Blends and Shelf Life Analysis

Abstract

The plantain stem is enriched with minerals and it is an underutilized agricultural produce which is low in cost. The study aimed to focus on the detection of phytochemicals present in refrigerated amla, guava and lemon juice incorporated plantain stem juice blends for increased shelf life. Plantain stem juice was added with acidic fruits such as lemon, guava and amla to increase the nutritional and sensorial property. The acceptability of Plantain stem juice blends were determined and standardized using consumer preference study. The formulated juice blends were bottled and studied for refrigerated real time storage stability. The analysis of proximate composition and screening of phytochemicals in plantain stem juice blends showed the good extent of bioactive properties within it and the lemon incorporated plantain stem juice blend showed the maximum sensory score of 7.83 with 12 days extension of shelf-life.
