Sapota is a delicious fruit introduced from tropical America. India is the largest producer of sapota in the world yielding more than 6.68 lakh tons with an average production of 13.20 tons per ha [1]. Modified atmosphere packaging (MAP) is a relatively cheap and convenient packaging technology that has the capacity to preserve natural quality of fresh fruits besides extending storage life [4]. A study was undertaken to establish the most effective storage temperature and packaging material for modified atmospheric packaging and storage of sapota. The shelf life of sapotas can be enhanced up to 21 days under modified atmosphere packaging stored at 10 0C. The shelf life of sapotas was 15 and 9 days at 15 0C and room temperature respectively. The shelf life of unpacked sapotas stored at room temperature was only 3 days. It has been concluded that the sapotas packed in LDPE pouches under modified atmosphere packaging and stored at 10oC temperature give a shelf life 21 days.
