Shelf Life Extension of Cashew apple by Modified Atmospheric Packaging
Cashew apples are highly perishable fruits and cannot be stored in ambient conditions for more than one day. The study of modified atmospheric packaging of cashew apple was aimed to extend the shelf life. Cashew apple (variety: VRI 3) was subjected to passive MAP of O2 – 21%, CO2- 0.03 %, and N2 78%. PP 60 µm film showed the lowest permeability of O2 and CO2 was 1999 mL/m2/day and 2935 mL/m2/day. The cashew apple packed with PP 60 µm had the lowest mass loss of 1.356 %, maximum retention of color 56.02 (‘L’), 36.96 (‘a’), 41.14(‘b’), firmness of 3.423 N, pH 0.259, and vitamin C of 404.35 mg/100g on the 9th day of storage under refrigerated condition. Fungal growth was also better controlled in PP 60 µm under refrigerated conditions and fungal growth was 9.73 x 104cfu/g on the 9th day. This study revealed that passive MAP of Cashew apple can extend the shelf life up to 9 days of storage.
