The rate of ethylene evolution is low, however, due to its characteristic high respiration rate (50-100 ml CO 2 per kg of fruits per hour at 20 ☌), the fruits are highly perishable and can be stored only for a quite short duration (Nunes et al., 2006). Strawberry has non climacteric ripening behavior of fruit. Antioxidant properties of strawberry have been mostly attributed to its polyphenol and vitamin content. Owing to its deep red colour it is a rich source of anthocyanin possessing high antioxidant activity (Sun et al., 2002) which is 1.3 times more than that of oranges, twice that of red grapes and twelve times that of apples and bananas (Guo et al., 1997). The edible portion accounting about 98% of the fruit is contains nutritionally important diverse elements. Introduction Strawberry (Fragaria × ananassa Duch.) is one of the most attractive, delicious, refreshing and nutritious soft fruit liked mainly for its delicate flavour and appearance. As a conclusion of the study, the comparative permeability of different packaging films were illustrated with respect to various components of MAP and their probable influence on the strawberry fruit quality enhancement may further be studied. Among the LDPE films, the LDPE 50 micron showed an optimum permeability for O2, CO2, as well RH. PP showed its higher permeability for CO2, O2 and RH between the in-and out-package environment.
PP showed a higher permeability for CO2, O2 and RH between the in-and out-package environment. The correlation study was performed using the sensor generated data to infer the existing interrelationship of various parameters for the respective packaging materials.
The fluctuations of important parameters in the in-package environment of the MAP were recorded using different sensors (Vernier CO2, O2, RH Sensor, and Vernier Stainless Steel Temperature Probe) supported with the data analysing software Logger Pro 3.9. Easily available different low cost packaging materials viz., low density polyethylene (LDPE) 25, 50 and 75 micron, polypropylene (PP) 25 micron, cellophane paper and Nalgene bottle under the ambient temperature condition were used.
The properties of in-package parameters of MAP viz., O2, CO2, relative humidity and temperature were studied under modified atmospheric packaging (MAP).
