Abstract

This study aims to determine the effect of brewing water temperature and cascara stirring variations on physical, chemical and microbiological characteristics. This research was conducted from November 2022 until completion at the Chemical Laboratory, Agricultural Product Processing and Microbiology, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. This study used a Factorial Completely Randomized Design (CRD), and investigated to factors, namely the temperature of the brewing water (80˚C, 90 ˚C and 100˚C) and the variation of stirring (using a 120 rpm magnetic stirrer, and without stirring). All experiment was carried out in triplicates. Parameters observed in this study were color physical characteristics (lightness (L*), redness (a*), yellowness (b*)), chemical characteristics (pH and total phenol), and TPC (Total Plate Count). The results showed that the brewing temperature had a significant effect on color (lightness (L*), redness (a*), yellowness (b*)), pH and total phenol in the samples after treatment; variations in stirring significantly affected the color (lightness (L*) and yellowness (b*)) and total phenol of the cascara tea samples; the interaction between the two treatments had a significant effect on color (lightness (L*) and yellowness (b*)), pH, and total microbes. The A3B1 treatment (temperature 100 ˚C, using a 120 rpm magnetic stirrer) is the best treatment because it has a lightness value of 23,56%, redness value of 4,05, yellowness of 0,21, pH of 4,46, total phenols of 11.61 and TPC 5,78 log CFU/mL.
