Abstract

The current study was carried out to check the effect of dissimilarity of calcium lactate concentrates on post-harvest life of apple fruit during storage. The treatments included Ao(control), ACaLa1(01%),  ACaLa2(02%) and ACaLa3(03%) respectively during storage at ambient temperature on the shelf life of apple fruit after harvesting. All the samples including control and treated samples were filled in flexible box and were investigated for physicochemical features (total soluble solid, pH, titratable acidity and decay index). The above mentioned quality parameters of whole apple fruits influenced treatments and storage. Storage outcome shown that increased in TSS was found from (12.13 to 14.31 °Brix), pH from (4.05 to 5.21), decay index from (0 to 44.14) during 3 months of storage. In control sample (4.47) highest mean value for pH was observed, while treatment CaLa 2% (4.30) was found minimum. Declining in treatment during storage was found in the following parameters Acidity and overall acceptability. The treatment CaLa 2% has shown the best result while showing maximum stability in physicochemical qualities of the fruit followed by CaLa 1% and CaLa 3% respectively.
