Abstract

This research aimed to determine the effect of soaking time of super red dragon fruit albedo (Hylocereus costaricensis) on the physical, chemical, microbiological and sensory characteristics of dragon fruit albedo infused water. The research was conducted at the Agricultural Product Chemistry Laboratory, Agricultural Product Sensory and Processing Laboratory, Agricultural Product Microbiology and Biotechnology Laboratory, Faculty of Agriculture, Sriwijaya University, Palembang. This research was carried out from October 2023 to November 2023. This research used a non-factorial Completely Randomized Design (CRD) method with 1 treatment factor, the length of soaking dragon fruit albedo which consisted of 6 levels (A = 2 hours, B = 4 hours, C = 6 hours, D = 8 hours, E = 10 hours, F = 12 hours) and each treatment was repeated 3 times. The observed parameters in this research include physical characteristics (color L* C* h*), chemical characteristics (vitamin C content, pH and total titrated acid), microbiological characteristics (Total Plate Count), and sensory characteristics (hedonic test of taste and color). The results of the research showed that the length of soaking time dragon fruit albedo infused water had a significant effect on physical characteristics (color L* C* h*), chemical characteristics (vitamin C content, pH and total titrated acid), microbiological characteristics (Total Plate Count), and sensory characteristics (color hedonic test). Treatment E (soaking time for 10 hours) was selected treatment based on vitamin C content, and fulfilled the requirements of SNI 7388:2009 total plate count of drinks.
