An ineffective postharvest handling of fruits can always pose a high risk to huge loss in agricultural business. In order to cater toconsumers’ requirements for food safety and freshness as well as to avoid postharvest loss of agricultural sector, many studies have been conducted to improve the shelf life of papaya fruits. In this paper, we aimed to study the effectiveness of alginate-based edible coating formulation in combination with essential oil to improve the shelf life of Sekaki papaya. The performance of this alginate formulation was compared against the method of propiconazole fungicide treatments and control fruits treatment. After treatment fruits were stored at 13˚C. All treated fruits were subjected to physico-chemical and molecular analysis at a regular 1 week intervals of week 1 up to 4 weeks of their storage period. The results showed that fruit coated with alginate formulation has significantly increased the shelf life of Sekaki papayas up to 4 weeks at 13˚C. The alginate coating formulation has successfully slowed down the ripening process and improved the protection against anthracnose disease of Sekaki papaya as compared to fungicide treatment and control. Molecular analysis revealed that overall transcript level of polygalacturanase (CpPG) and β- galactosidase (CpBGAL) genes for alginate coating formulation is lower than fungicide treatment and control, which is consistent to its longer shelf life. Altogether, combination of the alginate-based coating and Citrus hystrix essential oil is an effective and harmless alternative to prolong the in controlling antrachnose disease in papaya during storage period of Sekaki papaya.

Abstract

An ineffective postharvest handling of fruits can always pose a high risk to huge loss in agricultural business. In order to cater toconsumers’ requirements for food safety and freshness as well as to avoid postharvest loss of agricultural sector, many studies have been conducted to improve the shelf life of papaya fruits. In this paper, we aimed to study the effectiveness of alginate-based edible coating formulation in combination with essential oil to improve the shelf life of Sekaki papaya. The performance of this alginate formulation was compared against the method of propiconazole fungicide treatments and control fruits treatment. After treatment fruits were stored at 13˚C. All treated fruits were subjected to physico-chemical and molecular analysis at a regular 1 week intervals of week 1 up to 4 weeks of their storage period. The results showed that fruit coated with alginate formulation has significantly increased the shelf life of Sekaki papayas up to 4 weeks at 13˚C. The alginate coating formulation has successfully slowed down the ripening process and improved the protection against anthracnose disease of Sekaki papaya as compared to fungicide treatment and control. Molecular analysis revealed that overall transcript level of polygalacturanase (CpPG) and β- galactosidase (CpBGAL) genes for alginate coating formulation is lower than fungicide treatment and control, which is consistent to its longer shelf life. Altogether, combination of the alginate-based coating and Citrus hystrix essential oil is an effective and harmless alternative to prolong the in controlling antrachnose disease in papaya during storage period of Sekaki papaya.
