“…Both were significant different from non-treated treatments. There are a number of articles indicating Carnauba Wax properties on reducing weight loss in other fruits, such as Guava (Jacomino et al, 2003), oranges (Malgarim et al, 2007), but not for papaya fruits (De Freitas et al, 2019). On the other hand, nanoemulsions studies have been carried out in distinctive fruits with Carnauba Wax and essential oil nanoparticulate (Kim et al, 2013(Kim et al, , 2014Jo et al, 2014).…”

Papaya is a fruit of great economic importance worldwide, but still presents a high rate of postharvest losses. Among the different reasons explaining this phenomenom, intensive labor and inappropriate storage conditions are the main ones. Carnauba wax nanoemulsion (CWN) coating may be an alternative to this problem, preserving postharvest fruit quality. Therefore, an experimental CWN was developed and a set of three trials were conducted to evaluate its performance on storage of papaya fruits solo type. On the first trial, this coating was applied to the fruits at concentrations of 4.5, 9.0, 13.5 and 18.0% compared to control group (fruits coated with water). In a second trial, the best concentrations determined in the first one was used (13.5 and 18.0% respectively). On the last trial, CWN on a high concentration 18% was compared to commercially treated and untreated fruits. Fruits were stored for 12 to 20 days at 16 to 18°C and Relative Humidity upper to 70%. Physicochemical analyzes carried were soluble solids, titratable acidity, pH, weight loss, firmness, color and ethylene production, while postharvest disease incidence and severity was only performed on the last trial. Significant difference was observed on treatments with high CWN concentration (13.5 and 18.0%) in relation to reducing weight loss, delay ripening and decreasing ethylene production compared to untreated, commercial coating and even to low CWN concentrations. For disease severity it was observed a reduction on coated fruits with high CWN concentration when compared to control and commercial coating. CWN has a potential use for extending papaya postharvest shelf life.

“…These authors noticed that Valencia Delta sweet orange fruits receiving wax-coating treatment lost around 14% of their initial weight compared to 26% for the fruits without any coating treatment. Lower weight loss rates was also reported for Navelina and Washington navel oranges after 60 days of cold storage at 3 ± 1 • C and 80-95% RH, with a range of 1 to 5% of weight losses [49,50]. These results indicate that each citrus variety has different postharvest behavior depending on the postharvest handling and the length of the storage period.…”

The use of natural-based coatings is an eco-friendly approach that can be applied in citrus postharvest to preserve fruit quality and to prolong shelf life. Additionally, the study of antioxidant capacity of obtained by-products from fruits is of great value to mitigate better practices to manage the residues left from the juice processing industry. Under this context, the aim of this study was to investigate the use of carnauba wax/wood resin-based coating and cold storage on postharvest life of Valencia Late and Natal IAC sweet oranges, as well as the physicochemical quality and antioxidant capacity of its by-products. Mature fruits were harvested in 2019 and 2020 seasons. Initially, fruits were assessed for physicochemical quality and antioxidant capacity. Then, fruits were treated with carnauba wax and wood resin mixture and stored for 0, 15, 30, 45 and 60 days in a cold chamber. Fruit color index, weight loss, physicochemical quality and sensory profile of the fruits were monitored at harvest and during each cold storage period. Evaluations were performed in triplicates of 10-fruit. Valencia Late and Natal IAC fruits had proper quality in both years, attending the requirements of the fresh market and processing industry. Flavedo and albedo section displayed the highest concentration of bioactive compounds such as phenolics, flavonoids and antioxidant activity. The coating treatment associated with cold storage was efficient to preserve fruit color and to retard weight loss for both varieties up to 60 days. The sensory profile and quality of the carnauba wax/wood resin treated fruits were preserved all over the cold storage period, while uncoated fruits ranked low for most of the sensory attributes. Together, Valencia Late and Natal IAC fruits contain a high level of healthy beneficial compounds, which may be exploited as a natural source of low-cost antioxidants. Further, carnauba wax/wood resin coating associated with cold storage effectively reduce weight loss and color progression in sweet orange fruits, in addition to preserving overall physicochemical and sensory quality.

Peel yellowing and loss of fruit mass reduce the useful life of acid limes and limit their commercialization. The goal of the present study was to prolong the post-harvest preservation of acid limes using wax and packaging. Fruits were harvested, selected, disinfected, treated with fungicide, coated with Carnauba wax and placed in cardboard boxes wrapped with different plastic packaging. A fruit lot treated only with wax coating was used as a control. The fruits were stored at 10°C for 24 days followed by 6 days at 20°C. The gas atmosphere inside the packages was analysed during storage. The loss of mass, color index, titratable acidity, and total chlorophyll, ascorbic acid, soluble solids, acetaldehyde and ethanol concentrations of the fruits were measured. The combined use of wax coating and plastic Cryovac ® D-955 (Cryovac Brasil Ltda, São Paulo, Brazil) and Vegetal Pack ® (Eletropolimeros do Brasil Ltda, São Paulo, Brazil) films resulted in better post-harvest preservation of acid limes compared with only wax coating because the combined treatment maintained the green peel color following 30 days of storage in addition to resulting in lower loss of mass and maintaining chemical characteristics adequate for commercialization. The LDPE (low density polyethylene) and Xtend ® packaging (Stepac Brasil Ltda, São Paulo, Brazil), although they prevented peel degreening, did not result in an adequate atmosphere to maintain the quality of limes due to the accumulation of high concentrations of acetaldehyde and ethanol, especially for the LDPE packaging. LDPE drastically changed the atmosphere surrounding the fruit, resulting in loss of the characteristic pulp color, in addition to conferring an alcohol odor.
