Abstract

The purpose of this study was to determine the tendency of tamarind (Tamarindus indica L.) leaf extract damage at different temperatures during storage and to determine the storage temperature that can sustain the antioxidant damage of tamarind leaf extract (Tamarindus indica L.) during storage time. Tamarind leaf extract was stored for 4 (four) weeks at 3 (three) different temperature conditions (room temperature / 27 ± 2?C; cold temperature / 5 ± 2?C; and freezing temperature / -10 ± 2?C) and analyzed for total phenolic, antioxidant capacity. and weekly levels of vitamin C. The data obtained were tabulated and analyzed descriptively. The results of this study indicate that at room temperature (27 ± 2)?C, cold temperature (5 ± 2)?C, and freezing temperature (-10 ± 2)?C, total phenolic, vitamin C levels, and antioxidant capacity have a tendency to decrease during storage. four weeks. The highest decrease in total phenolic occurred at room temperature (27 ± 2)?C, the highest decrease in vitamin C levels and antioxidant capacity occurred at freezing temperatures (-10 ± 2)?C. Storage with cold temperatures (5 ± 2)?C can retain the antioxidant content of tamarind leaf extract for four weeks and is the best storage condition. Keywords : Storage temperature, tamarind leaves extract, totalphenolicc, antioxidant, vitamin C
