The pH and total soluble solids were measured using a pH meter
(Eutech) and a hand refractometer (Erma, Japan) respectively
(Ranganna, 1986). Total titratable acidity and free fatty acid (Acid
value) were estimated according to the method given in Sadasivam
and Manickam (2007). The total titratable acidity was calculated
with respect to citric acid.
