“…This problem can be potentially harmful, since a small set of rotten and sporulated fruits can contaminate the whole batch, especially during storage or transport. Penicillium digitatum (the cause of green mould) and Penicillium italicum (the cause of blue mould) are two examples of the most deleterious fungi causing fruit decay, and they affect several cultivars over the world [2,3].…”

Ferrer, VIS/NIR hyperspectral imaging and N-way PLS-DA models for detection of decay lesions in citrus fruits, Chemometrics and Intelligent Laboratory Systems (2016), AbstractIn this work an N-way partial least squares regression discriminant analysis (NPLS-DA) methodology is developed to detect symptoms of disease caused by Penicillium digitatum in citrus fruits (green mould) using visible/near infrared (VIS/NIR) hyperspectral images.To build the discriminant model a set of oranges and mandarins was infected by the fungus and another set was infiltrated just with water for control purposes. A double crossvalidation strategy is used to validate the discriminant models. Finally, permutation testing is used to select a few bands offering the best correct classification rates in the validation set. The discriminant models developed here can be potentially implemented in a fruit packinghouse to detect infected citrus fruits at their arrival from the field with affordable multispectral (3-5 channels) cameras installed in the packinglines.

“…The antifungal activity, either in vitro or in vivo, of many essential oils extracted from plants or fruits such as birch, bergamot, cumin, cinnamon, citrus, clove, lemongrass, oregano, thyme, or tea tree against major citrus pathogens, particularly P. digitatum and P. italicum, has been reported [15,96]. Among them, only a limited amount has been tested as potential ingredients of chitosan coatings.…”

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.

“…On a broad range of commodities, including citrus, the effectiveness of several organic and inorganic salts, considered as generally recognized as safe (GRAS) compounds, has been investigated for the control of postharvest pathogens . Among these, sodium carbonate (Na 2 CO 3 ) and sodium bicarbonate (NaHCO 3 ) are used for controlling pH, taste, and texture, and their antifungal activity has been widely tested for the control of postharvest citrus green and blue molds …”

The rapid increase in pectin methyl esterase activity under alkaline conditions is presumably the strategy of the pathogen to lower the pH, soon after the initiation of infection, in order to restore an optimal environment for the subsequent polygalacturonase and pectin lyase action. In fact, at the same time, a low pH delayed the enzymatic activity of polygalacturonase and pectin lyase, the two enzymes that actually cleave the α-1,4-linkages between the galacturonic acid residues. © 2018 Society of Chemical Industry.
