Respiration rate, sensory attributes, change in color, physiological loss in weight, chlorophyll and beta - carotene content and microbial loads were determined during storage of mint leaves at 10 and 27áµ’C to find an optimal gas composition to extend the shelf life. The Low Density Poly Ethylene (LDPE) bags with a thickness of 152 µ which recorded the lowest permeability to oxygen (1067 ml/m2/day) was selected and used for packaging mint leaves. The harvested mint leaves were cleaned and subjected to pre chilling and pre-cooling treatment and packaged in low density polyethylene (LDPE) bags with a product volume ratios Viz., 1:18, 1:11, and 1:8 to assess the respiration rate under ambient and refrigerated condition using the permeable system. Optimization of gas composition for MAP was done by calculating the respiration rate using Michaelis–Menten equation. Based on the respiration rate, a gas composition of 5% O2, 5% CO2 and 90% N2 was found to be the best in the product volume ratio of 1:8 which recorded the lowest respiration rate, and a slight changes in the physico-chemical parameters, was recorded during the storage period of 30 days. The keeping quality of leaves stored under ambient conditions had a shelf life of 4 days when compared to 20 days under refrigerated condition. The MA packaged mint leaves kept under refrigerated condition had more shelf life than at ambient condition.
