Abstract

Ziziphus mauritiana is a highly perishable fruit of Asiatic origin, and it is difficult to keep fresh after harvest. Rapid ripening, quality loss and sped up ethylene synthesis are the critical factors of short shelf life. In this study, we studied the effectiveness of modified atmospheric packaging on the qualitative parameters of Indian jujube fruit. Fruits were picked at the colour changing stage and packaged in polyethylene bags with one concentration of O2 (2%) in combination with three CO2 concentrations (5, 10, and 15%) and kept at 12°C with 85-90 % RH for 35 days. We measured total soluble solids (TSS), titratable acidity (TA), total sugar, reducing sugar, ascorbic acid, and total phenol during storage. Fruit stored in an atmosphere with a environmental gaseous composition served as a control and quickly lost important qualitative characteristics, as seen by faster colour changes, softening, decreased acidity, and increased sugars and total soluble solids. Because of the delay
