“…For example, blue mold, caused by the species Penicillium expansum L., can lead to significant postharvest losses of apple, pear, stone fruits, kiwifruit, many berries, pomegranate, persimmon, and other subtropical and tropical fruits [3][4][5]. The two postharvest diseases that account for the largest decay losses of citrus fruits worldwide are green and blue molds, caused by Penicillium digitatum (Pers.:Fr.)…”

Control of postharvest diseases of fresh fruits has relied for many years on the continuous use of conventional chemical fungicides. However, nonpolluting alternatives are increasingly needed because of human health and environmental issues related to the generation of chemical residues. Low-toxicity chemicals classified as food preservatives or as generally recognized as safe (GRAS) compounds have known and very low toxicological effects on mammals and minimal impact on the environment. Among them, inorganic or organic salts such as carbonates, sorbates, benzoates, silicates, etc., show significant advantages for potential commercial use, such as their availability, low cost, and general high solubility in water. Typically, these substances are first evaluated in vitro against target pathogens that cause important postharvest diseases. Selected salts and concentrations are then assayed as aqueous solutions in in vivo tests with target fresh fruit. Laboratory and small-scale experiments are conducted with fruit artificially inoculated with pathogens, whereas naturally infected fruit are used for large-scale, semicommercial, or commercial trials. Another approach that is increasingly gaining importance is evaluating GRAS salts as antifungal ingredients of novel synthetic edible coatings. These coatings could replace the fungicide-amended commercial waxes applied to many fruit commodities and could be used for organic or “zero-residue” fresh fruit production systems.

The Antifungal Potential of Carvacrol against Penicillium Digitatum through 1H-NMR Based Metabolomics Approach

et al. 2019

Carvacrol (5-Isopropyl-2-methylphenol), a volatile oil constituent, mainly exists in Labiaceae family plants. Carvacrol has long been studied for its natural antifungal potential and food preservative potential. However, its exact mode of action, especially against Penicillium digitatum (P. digitatum), remains unexplored. Herein, a 1 H-NMR-based metabolomic technique was used to investigate the antifungal mechanism of carvacrol against P. digitatum. The metabolomic profiling data showed that alanine, aspartate, glutamate, and glutathione metabolism were imbalanced in the fungal hyphae. A strong positive correlation was seen between aspartate, glutamate, alanine, and glutamine, with a negative correlation among glutathione and lactate. These metabolic changes revealed that carvacrol-induced oxidative stress had disturbed the energy production and amino acid metabolism of P. digitatum. The current study will improve the understanding of the metabolic changes posed by plant-based fungicides in order to control citrus fruit green mold caused by P. digitatum. Moreover, the study will provide a certain experimental and theoretical basis for the development of novel citrus fruit preservatives.aroused by excessive use of certain routine and synthetic antifungal agents. Over the past few decades, the intentions have been to ensure the hygiene and safety levels of fruit products along with promoting maximum biodegradability. In order to achieve this ambition, researchers are still trying to screen natural products with strong antifungal potential from plants. Moreover, it has also been tried to explore new preservation technologies that can replace synthetic fungicides. Compared with synthetic fungicides, natural antifungal substances have attained much attention in recent years [6][7][8][9].Various essential oils refined from Melaleuca alternifolia have strong inhibitory effects on multiple fungal strains, particularly P. italicum Wehmer and P. digitatum Sacc., and hence can be used as natural preservatives in agricultural and food processing [10]. Previously we have reported that cinnamaldehyde contained in cinnamon has a good antifungal effect against P. italicum and clarifies the method for dynamic detection of the antifungal effect of cinnamaldehyde [11]. In addition, GC-MS and GC-FID techniques successfully separated the essential oils components viz. limonene (87.02%), linalyl acetate (53.76%) and linalool (39.74%) from peels, leaves and flowers of Citrus aurantium var amara, neroli oil appeared as the best fungistatic agent, which reduced the P. digitatum sporulation to 25 % at a 50 mg/mL concentration of oil [12].Carvacrol (5-Isopropyl-2-methylphenol) is the major volatile oil constituent from Labiaceae family plants, such as oregano, mint, and thyme [13]. Carvacrol has many medicinal and edible applications, including antifungal, antimicrobial, anti-inflammatory, insecticidal, antitumor, and other effects [14]. Carvacrol inhibited the growth of P. digitatum and P. italicum in in vitro and in vivo experiments of l...

“…Kiwifruit (Actinidia deliciosa) is very popular among consumers due to its high nutritional value. The harvested area and yield of kiwifruit in the world has continuously increased in the 21st century [1,2]. However, postharvest diseases caused by pathogens are a serious problem for the storage of kiwifruit and have resulted in decay and a decrease in quality, shelf life, and consumer acceptability [3,4].…”

Soft rot caused by Botryosphaeria dothidea and Phomopsis sp. is a critical disease in kiwifruit. In order to efficiently control soft rot, a 28.6% chitosan composite film (CCF) containing chitosan, dextrin, ferulic acid, calcium, and auxiliaries was successfully developed. The results showed that CCF had a strong inhibitory effect on mycelia growth of B. dothidea and Phomopsis sp., with mycelial EC50 values of 68.11 and 50.34 mg L−1, respectively. The concentration of 0.71–1.42 g L−1 CCF had noticeably preventive and curative effects against soft rot. The spray of CCF before pathogen infection effectively reduced the incidence of soft rot, remarkably increased the content of resistance compounds, and activated the activity of defense enzymes. Moreover, it notably enhanced the yield and quality and prolonged the shelf life of kiwifruit. Therefore, the excellent control effects of CCF against soft rot might be associated with its film-forming property and antifungal activity, which prevent infection and induce plant defense mechanisms. The concentration of 0.71–1.42 g L−1 CCF was optimal for the field application before the onset of disease symptoms in plants with B. dothidea and Phomopsis sp.
