Accelerated shelf-life test (Aslt) of batuan [garcinia binucao (blanco) choisy] fruit powder

Abstract

The study evaluated the storage characteristics of batuan fruit powder by Accelerated Shelf-life Test (ASLT) where the product was stored at elevated temperatures of 37°C, 50°C, and 60°C. During the experiment, the physicochemical (whiteness index, pH, total soluble solids, titratable acidity) and sensory (color, aroma, off-odor, general acceptability) characteristics of the product were monitored. The kinetics of non-enzymatic browning (NEB) was found to be a pseudo-first-order reaction in terms of whiteness index (WI). The effect of temperature on the rate constant for NEB was observed to follow Arrhenius Law such that the activation energy is 105.9 kJ mol-1 and Q10 is 3.90. The shelf-life of the product at room temperature was predicted to be 202 days (6.7 months).
