“…The antifungal effects of chitosan were related to direct fungitoxic activity against the pathogen [84]. In another study [77], chitosan at 2% was applied to "Navel" oranges 24 h before inoculation with P. digitatum or P. italicum and it was observed that, after 23 days at 20 °C, disease incidence (proportion of infected fruit) and severity (lesion diameter) were significantly lower on coated samples than on uncoated controls. Chitosan antifungal activity was higher against blue mold than against green mold.…”

“…Particularly, its beneficial effect for postharvest disease reduction has been reported for a wide variety of fresh horticultural produce including citrus, apples, mango, grapes, strawberries, blueberries, lettuce, carrots, or tomatoes. Its antimicrobial activity, however, depends on several factors such as the type of chitosan, degree of acetylation, molecular weight, concentration, medium pH, target microorganism, and the presence of other ingredients in the chitosan coating [25,35,[76][77][78][79]. In addition to its antimicrobial and antifungal activity, chitosan has been considered as a good candidate for postharvest treatment and long-term storage of fresh fruits and vegetables because of other important properties, such as lack of toxicity to mammals and consequent edibility, biodegradability, biocompatibility with many other compounds, and multifunctionality, greatly derived from its capacity to form coatings [62,75].…”

Antifungal Edible Coatings for Fresh Citrus Fruit: A Review

According to their origin, major postharvest losses of citrus fruit are caused by weight loss, fungal diseases, physiological disorders, and quarantine pests. Cold storage and postharvest treatments with conventional chemical fungicides, synthetic waxes, or combinations of them are commonly used to minimize postharvest losses. However, the repeated application of these treatments has led to important problems such as health and environmental issues associated with fungicide residues or waxes containing ammoniacal compounds, or the proliferation of resistant pathogenic fungal strains. There is, therefore, an increasing need to find non-polluting alternatives to be used as part of integrated disease management (IDM) programs for preservation of fresh citrus fruit. Among them, the development of novel natural edible films and coatings with antimicrobial properties is a technological challenge for the industry and a very active research field worldwide. Chitosan and other edible coatings formulated by adding antifungal agents to composite emulsions based on polysaccharides or proteins and lipids are reviewed in this article. The most important antifungal ingredients are selected for their ability to control major citrus postharvest diseases like green and blue molds, caused by Penicillium digitatum and Penicillium italicum, respectively, and include low-toxicity or natural chemicals such as food additives, generally recognized as safe (GRAS) compounds, plant extracts, or essential oils, and biological control agents such as some antagonistic strains of yeasts or bacteria.

“…Our previous work also indicated that chitosan treatment can induce disease resistance in navel orange [1]. However, limited information is available regarding the control effects of postharvest oligochitosan treatment on anthracnose and its related mechanisms in citrus fruit.…”

“…Penicillium digitatum (green mold) and Penicillium italicum (blue mold) are the major pathogens that infect citrus fruits after harvest, which can cause serious annual losses [1]. Anthracnose, another postharvest disease caused by Colletotrichum gloeosporioides Penz., can lead to considerable economic losses, particularly with prolonged storage, and can often be ignored.…”

“…This is evidenced by peroxidase (POD) and CAT activity level increases in the protein extract of some edible cultivars like tomato, guava, and sweet wormwood that were treated with CH (Ortega-Ortíz et al, 2007;Guan et al, 2009;Lei et al, 2011;Hong et al, 2012). The inhibition of CAT activity (Zeng et al, 2010) is important in plant development, defense, aging, and senescence too (Yang and Poovaiah, 2002). Although, there are multiple reports of CH application in food production, there are not reports for the effect of CH application on crop nutritional value.…”

Abstract:Objective: To evaluate the effect of chitosan (CH) and hydrogen peroxide (H 2 O 2 ) seed coatings and seedling sprinklings on two different maize varieties by measuring their phenology, the H 2 O 2 presence, the catalase (CAT) activity, and the protein quantity. Methods: Seven groups of ten seeds for each maize variety were treated with CH (2% (20 g/L) and 0.2% (2 g/L)) or H 2 O 2 (8 mmol/L) by coating, sprinkling, or both. Germination and seedling growth were measured. One month after germination, the presence of H 2 O 2 in seedlings in the coated seed treatments was evaluated. Protein content and CAT activity were determined under all treatments. Results: H 2 O 2 seed coating enhanced the germination rate and increased seedling and stem length in the quality protein maize (QPM) variety. Seedlings had a higher emergence velocity under this treatment in both varieties. CH and H 2 O 2 sprinklings did not have an effect on seedling phenology. Exogenous application of H 2 O 2 promoted an increase of endogenous H 2 O 2 . CH and H 2 O 2 seedling sprinkling increased the protein content in both maize varieties, while there was no significant effect on the CAT activity of treated seeds and seedlings. Conclusions: CH and H 2 O 2 enhance some phenological and biochemical features of maize depending on their method of application.
