Abstract In this study, major physicochemical propertieslike total solid, total soluble solid, reducing sugar%, invert sugar%, ascorbic acid%, titratable acidity, pH, sodium, potassium, sweetness, andcolour based properties, were studied. The result reflectedsolid to water ratio of 5:95, with highpotassium contentand other parameter with a desirable limit.The effectof thermal processing on colourbased changes in tender coconut waterwas examined between 50to 90?C and time of exposurefor 60 sec to 120 sec. The colourchangewas investigated using a 22experimental design. Further kinetic studyof colourchange was also performedat the best result obtained from above design. Kinetic studies showed that the thermal inactivation of colourdevelopment at 90?C, followed first-order kinetics. Thereaction rate constant (k),Decimal reduction time (D90)of thermal inactivationof colourdevelopment, were0.004 Sec-1and 221.22 Sec.respectively.
