“…Similar results on the efficacy of MAP to reduce weight loss of pomegranates have also been reported in previous works [19,24,25,55]. The effect of MAP on weight loss reduction can be directly attributed to a limitation of water vapor diffusion through the film that generates higher RH within the package [49]. High RH could also prevent the coating from shrinking and breaking after prolonged storage, which would explain the synergic effect observed with the combination of both technologies at the end of the storage period.…”

“…Both salts, SB and PBC, are commonly used as additives in the food industry and their potential to effectively control postharvest fungal decay on a variety of fresh fruits and vegetables during storage has been shown in several research works [28,44,48]. The number of studies on the use of GRAS salts to control pomegranate postharvest diseases is scarce [49]. The use of aqueous solutions of some salts such as sodium bicarbonate, sodium carbonate, and potassium sorbate was tested alone or in mixtures by Palou et al [41].…”

Antifungal Hydroxypropyl Methylcellulose (HPMC)-Lipid Composite Edible Coatings and Modified Atmosphere Packaging (MAP) to Reduce Postharvest Decay and Improve Storability of ‘Mollar De Elche’ Pomegranates

Pomegranate exhibits important postharvest quality losses that limit its storage potential, caused mainly by weight loss, chilling injury and fungal diseases. In this work, we evaluated the effect of novel hydroxypropyl methylcellulose (HPMC) edible coatings (ECs) formulated with three different lipids (beeswax (BW), carnauba wax, and glycerol monostearate), as hydrophobic components, and two different GRAS salts (potassium bicarbonate (PBC) and sodium benzoate (SB)), as antifungal ingredients, to control weight loss and natural fungal decay of ‘Mollar de Elche’ pomegranates during storage at 20 °C. Afterwards, selected antifungal ECs and commercial modified atmosphere packaging (MAP) films were assayed alone or in combination to control natural decay and preserve fruit quality of pomegranates stored at 5 °C for 4 months plus 1 week at 20 °C. Results showed that ECs amended with SB reduced pomegranate latent infections caused by Botrytis cinerea and wound diseases caused by Penicillium spp. Moreover, MAP technologies were confirmed as an efficient mean to preserve freshness, prevent fruit shriveling and rind browning, and reduce fungal decay, thus extending storage life of pomegranates. The combination HPMC-BW-SB + MAP was the most promising treatment as it reduced weight loss and decay, without negatively affecting the fruit physicochemical and sensory quality.

“…For pomegranate (Punica granatum L.), a highly nutritional and commercially important fruit, pathogens, namely B. cinerea and Penicillium spp., were identified as the main causal agents of wound and latent infections leading to decay [8,18,19]. When the fruit is dipped in FLU before cold storage, the fungicide solution inhibits fungal spores on the calyx part of the fruit, thereby reducing microbial proliferation [15,19]. However, at present, consumer preference for fresh produce without fungicide application is increasingly growing, and several countries have imposed strict regulations on the minimum residue levels for fungicides [19].…”

However, at present, consumer preference for fresh produce without fungicide application is increasingly growing, and several countries have imposed strict regulations on the minimum residue levels for fungicides [19]. Furthermore, studies have proven that several pathogens develop resistance to synthetic fungicides, and waste disposal of most fungicides poses a threat to the environment [20].…”

A Comparative Study of Antimicrobial and Antioxidant Activities of Plant Essential Oils and Extracts as Candidate Ingredients for Edible Coatings to Control Decay in ‘Wonderful’ Pomegranate

This study determined the antimicrobial and antioxidant activity of lemongrass (LO), thyme (TO), and oregano (OO) essential oils and ethanolic extracts of pomegranate peel (PPE) and grape pomace (GPE) as candidate ingredients for edible coatings. Antifungal effects against Botrytis cinerea and Penicillium spp. were tested using paper disc and well diffusion methods. Radical scavenging activity (RSA) was evaluated using 2,2-diphenyl-1-picrylhydrazyl and 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid assays. Gas chromatography-mass spectrometry analysis identified limonene (16.59%), α-citral (27.45%), β-citral (27.43%), thymol (33.31%), paracymene (43.26%), 1,8-cineole (17.53%), and trans-caryphellene (60.84%) as major compounds of the essential oils. From both paper disc and well diffusion methods, LO recorded the widest zone of inhibition against tested microbes (B. cinerea and Penicillium spp.). The minimum inhibitory concentrations of LO against B. cinerea and Penicillium spp., were 15 µL/mL and 30 µL/mL, respectively. The highest (69.95%) and lowest (1.64%) RSA at 1 mg/mL were recorded for PPE and OO. Application of sodium alginate and chitosan-based coatings formulated with LO (15 or 30 µL/mL) completely inhibited spore germination and reduced the decay severity of ‘Wonderful’ pomegranate. Lemongrass oil proved to be a potential antifungal agent for edible coatings developed to extend shelf life of ‘Wonderful’ pomegranate.

“…Hence, the relative tolerance or susceptibility of fruits to disease has often been used for selecting disease-resistant genotypes for subsequent peach breeding. In addition, considering the recent drive for alternative technologies effective to control post-harvest diseases [177,182,183], in particular of stone fruits [3], any documentation of composites inhibiting BR development would have an influence on the breeding schemes and could be particularly useful to maintain fruit quality after harvesting, in the peach market. Having into account that the genetic control for the tolerance to Monilinia spp.…”

Peach Brown Rot: Still in Search of an Ideal Management Option

2018

Abstract:The peach is one of the most important global tree crops within the economically important Rosaceae family. The crop is threatened by numerous pests and diseases, especially fungal pathogens, in the field, in transit, and in the store. More than 50% of the global post-harvest loss has been ascribed to brown rot disease, especially in peach late-ripening varieties. In recent years, the disease has been so manifest in the orchards that some stone fruits were abandoned before harvest. In Spain, particularly, the disease has been associated with well over 60% of fruit loss after harvest. The most common management options available for the control of this disease involve agronomical, chemical, biological, and physical approaches. However, the effects of biochemical fungicides (biological and conventional fungicides), on the environment, human health, and strain fungicide resistance, tend to revise these control strategies. This review aims to comprehensively compile the information currently available on the species of the fungus Monilinia, which causes brown rot in peach, and the available options to control the disease. The breeding for brown rot-resistant varieties remains an ideal management option for brown rot disease control, considering the uniqueness of its sustainability in the chain of crop production.
