The pH, total soluble solid (TSS) and titrable acidity (TA) of the sample were measured according to the methods described in Ranganna (2007). A digital pH meter (model: CL 46 +; maker: Toshcon, India) and a digital refractometer (model: PAL-1; maker: Atago, Japan) were used to measure the pH and TSS of the samples, respectively. Acidity of the puree sample was determined by titrating the sample against a standard alkali (sodium hydroxide solution) and quantified as g citric acid per 100 g puree (considering citric acid as the major contributing acid present in the sample).
