The fruit samples were prepared by taking 100 g of peeled tomato and the juice was extracted with a small amount of Oxalic acid. The juice was transferred to a conical flask and allowed to stand for 30 minutes in dark. The nonsedemented layer of juice was transfer to 100 ml flask, diluteed with 2% Oxalic acid making up the volume. From both the standard and sample solutions, 10 ml was taken for titration against the dye solution. A balnk sample was also titrated to determine the Dye factor.
