Efficacy of chitosan‐coated paper incorporated with vanillin and ethylene adsorbents on the control of anthracnose and the quality of Nam Dok Mai mango fruit

Abstract

Mango fruit is perishable and susceptible to anthracnose. Active-coated paper is proposed as potential packaging for commercial application in wrapping mango fruit to control anthracnose and delay the ripening process of fruit. The surface of white standard bleached paper was coated using a vanillin-chitosan coating solution containing varying amounts of zeolite or activated carbon at 0% (vanillin paper), 0.1%, 0.2%, and 0.4%, w/v of ethylene absorbers. The first objective was to study the effect of absorber types and their amounts on ethylene removal. After that, the coating formulation that provided the highest ethylene removal was selected to wrap commercial Nam Dok Mai mango fruit to study the quality changes. The efficacy of activecoated paper on the severity index of anthracnose disease, change in physicochemical properties, and sensory acceptability during storage (13°C, 90% relative humidity (RH) for 30 days) were investigated. It was found that vanillin-chitosan coated paper containing 0.2% (w/v) of zeolite (zeolite paper) exhibited the highest capacity of ethylene adsorption. Zeolite paper could delay the disease incidence of wrapped mango fruit and provided the lowest severity index of anthracnose disease throughout storage. Moreover, changes in physicochemical qualities (weight loss, firmness, titratable acidity, total soluble solid, and color) of mango fruits wrapped in zeolite paper was quite low, compared with those wrapped with vanillin and uncoated papers. In addition, mango wrapped by zeolite paper had the highest sensory acceptance score. The results suggest that zeolite paper can efficiently be applied as wrapping to extend the postharvest life of mango fruit.

Photoactivated TiO2 Nanocomposite Delays the Postharvest Ripening Phenomenon through Ethylene Metabolism and Related Physiological Changes in Capsicum Fruit

“…Thus, TiO2-NPs in plants are exercised as a photocatalytic agent for ET with strong reducing activity under UV irradiation [31,32]. In postharvest storage of fruit and vegetables, the application of such an ET scavenger is thus entrusted more with its non-toxicity as well as less invasiveness within the fruit coats [33]. This have got evident in our experiment when Capsicum recorded a less bioaccumulation of Ti in the fruit pulp over the control.…”

Recent Advancements of Polysaccharides to Enhance Quality and Delay Ripening of Fresh Produce: A Review

“…Moreover, active chitosan/vanillin coating containing zeolite that exhibits the highest capacity of ethylene scavenger activity delayed the disease incidence of Nam Dok Mai mango fruit by providing the lowest onset of anthracnose disease. As mentioned in previous research, chitosan/vanillin coating was able to retain the physicochemical qualities of mango fruits, including weight loss, firmness, titratable acidity, total soluble solid, and color [ 52 ]. Chitosan-based coating supplemented with vanillin and geraniol exhibited bactericidal effects on apple cubes stored under refrigerated temperatures by retarding the growth of mesophiles, psychrotrophs, and yeasts and molds [ 53 ].…”

The Emergence of Edible and Food-Application Coatings for Food Packaging: A Review

“…The film has effectively and efficiently maintained the packed bananas’ humidity and physical appearances. In addition, Jaimun and Sangsuwan [ 186 ] incorporated vanillin and ethylene adsorbents onto chitosan-coated paper to preserve the quality of Nam Dok Mai mango fruit. The coated paper contained varying concentrations of zeolite or activated carbon at 0%, 0.1%, 0.2% and 0.4%, w/v of the ethylene absorbers.…”
