Pericarp browning is the major limitation for long term storage oflitchi fruit following harvest. Rapid losses of moisture from peel,oxidation of phenolic compounds along with breakdown of antho-cyanin pigments by the enzymes polyphenol oxidase (PPO) and/orperoxidase (POD) are the main causes of pericarp browning (Jianget al., 2005). Commercially, litchi fruits after harvest are fumigatedwith sulphur dioxide to minimize browning of fruit pericarp duringstorage. But, this treatment adversely affects consumers and pack-house workers by causing health hazards. This treatment also altersthe fruit taste by increasing its acidity. During fumigation with sul-phur dioxide, fruits absorb 30–65% of applied sulphur which isbeyond the maximum permissible limit of 10 ppm, permitted by
