Abstract
Papaya fruit is climacteric in nature and susceptible to chilling, and it exhibits high postharvest losses. Among the various eco-friendly and health friendly postharvest quality preservation approaches, plant extracts (PEs) and essential oils (EOs) have drawn serious attention to the postharvest horticulturists as promising biopreservatives for postharvest quality retention of fruits. Thus, in this study, the efficacy of selected PE and EO was investigated for shelf-life extension and keeping quality retention of papaya fruit during ambient storage (25 ± 4°C and 65% ± 5% relative humidity). Papaya fruits cv. “Red Lady” were dip coated with “pummelo peel extract” (1 % v/v), “pummelo EO” (0.1% v/v), “turmeric leaf extract” (TLE) (1% v/v), “turmeric EO” (0.1% v/v), and “neem EO” (2% v/v). Results revealed that all the selected coatings significantly influenced postharvest storage life and quality of papaya fruit, but the TLE (1% v/v) treatment was found best in extending keeping quality of fruit while positively affecting all the studied postharvest attributes. The TLE application exhibited the highest control over physiological and enzymatic activities of fruit. In addition, TLE treatment exhibited the highest consumer preference and sensory score while minimizing the postharvest decay significantly over the control. Moreover, TLE coating enhanced the overall fruit quality of papaya by positively affecting nutritional (total carotenoids, ascorbic acid) and biochemical (total soluble solid, titratable acidity, and total phenolics) attributes throughout the storage. Novelty impact statement The selected plant extracts (Pes) and essential oils (EOs) (pummelo peel extract, turmeric leaf extract [TLE], pummelo EO, turmeric EO, and neem EO) postharvest coating showed promising potential in extending the shelf life of papaya fruit without impairing keeping quality. However, among the selected treatments, the TLE exhibited the best results. TLE extended the shelf life of papaya fruit by 3 days, maintained quality and enhanced the consumer preference. Postharvest preservation of papaya fruit using PE and EO derived from turmeric and pummelo was unexplored till date. Furthermore, the attempted non-chemical edible coating approach is cost-effective as well as health and eco-safe.
