This study aimed at determining the respiration rate of fresh-cut 'Deveci' pears and studying the effects of modified atmosphere packaging (MAP) on its quality. Respiration rate decreased with decreasing O 2 level and it was determined as 1.04 ml O 2 /kg/hr or 1.16 ml CO 2 /kg/hr, under 4% O 2 +5% CO 2 gaseous environment at 4°C. Michaelis-Menten with no inhibition was the best model to fit the respiration data. MAP under 2.15% O 2 +8.70% CO 2 equilibrium atmosphere resulted in a lower total color change, a*-value, chroma, and a higher hue angle and L*-value compared to the air-control during 8-day storage at 4°C. The firmness of pear slices was better maintained in the MAP.The MAP treatment was successful in controlling the total soluble solids, pH, and titratable acidity of the fresh-cut pears. As a result, MAP of fresh-cut 'Deveci' pears has an important potential to preserve the physicochemical properties of the product. Novelty impact statementRespiration rate of fresh-cut 'Deveci' pears was reduced by 3-4-fold to 1.04 ml O 2 / kg/hr or 1.16 ml CO 2 /kg/hr values by modified atmosphere of 4% O 2 and 5% CO 2 at 4°C. Michaelis-Menten model with no CO 2 inhibition was the best model for respiration rate as a function of O 2 and CO 2 concentrations. Modified atmosphere packaging improved texture and color, and maintained acidity and total soluble solids of fresh-cut 'Deveci' pears during storage.
