After that, 10 mL of 4% oxalic acid was added, and the dye was titrated. The amount of ascorbic acid was equivalent to the amount of dye that was consumed until the moment at which pink coloring appeared. In 4% oxalic acid, two milliliters of the sample were extracted, and 12 milliliters of a known volume were prepared and centrifuged. A titration against the dye was performed using five milliliters of this supernatant, to which 10 milliliters of 4% oxalic acid was added. The quantity of titer in the formula corresponded to this dye consumption. 2.3.5 Shelf life Tomato’s shelf life was determined by calculating the number of days required to attain the last stage of ripening and then at the point where the fruit could still be sold i.e., it remained acceptable for marketing. 2.3.6 Marketable fruit (%) The percentage of marketable fruit was calculated to evaluate the postharvest quality and shelf-life maintenance of the treated samples. The calculation was performed using the following formula: 2.4 Statistical analysis Data was systematically arranged using observed parameters, and analysis of variance was performed using EXCEL and GENSTAT. The available literature was used to assist in the analysis of the data and the discussion of the findings. 3 Results and Analysis 3.1 Total soluble solid (º Brix) ANOVA showed statistically similar values between treatments (GA3, CaCl2, SA, and the control) and TSS in the tomatoes (Table 2). The TSS values ranged from 4.35º Brix to 5.26º Brix during the 15-day storage period, where control had the maximum TSS value of 5.26º Brix. Among the treatments, T4 (0.5% CaCl2) exhibited the lowest TSS value, followed by T1 (0.1% GA3) than other treatments.
