Evaluation of sodium benzoate and other food additives for the control of citrus postharvest green and blue molds

Abstract

Evaluation of sodium benzoate and other food additives for the control of citrus postharvest green and blue molds.

Alternative Eco-Friendly Methods in the Control of Post-Harvest Decay of Tropical and Subtropical Fruits

“…This may be due to the fact that it changes the plasma membrane, thus inhibiting essential metabolic functions. Some authors have described that high concentrations of sodium benzoate inhibited the growth of A. Alternata [80], and this is attributed to the fact that weak acids within the cell create a dissociation, causing that protons and anions accumulate and cannot cross the plasma membrane again [81]. Bicarbonate salts, also were effective to inhibit the growth of various pathogens, the efficiency of this salt is attributed to the fact that it creates cellular ionic imbalances affecting the synthesis of polyamines and DNA during cell division [82,83].…”

Starch-glyceryl monostearate edible coatings formulated with sodium benzoate control postharvest citrus diseases caused by Penicillium digitatum and Penicillium italicum

“…Among the different disease management alternatives, GRAS salts present important advantages, including high water solubility, availability, and general low cost (Palou, 2018). Thus, their potential to control citrus postharvest decay as aqueous solutions or as ingredients of composite edible coatings (ECs) is an active research field (Palou et al, 2015;Montesinos-Herrero et al, 2016). The effectiveness of GRAS salts, including benzoates, bicarbonates, carbonates, metabisulfites, parabens, silicates, and sorbates, for control of major postharvest citrus diseases has been demonstrated in previous studies (Palou et al, 2002;Smilanick et al, 2008;Valencia-Chamorro et al, 2009a;Askarne et al, 2013;Moscoso-Ramírez et al, 2013;Youssef et al, 2014;Montesinos-Herrero et al, 2016;Guimarães et al, 2019;Martínez-Blay et al, 2020a;2020b).…”

We have found that, among these salts, aqueous solutions of sodium benzoate (SB) had substantial curative activity against citrus GM and BM (Montesinos-Herrero et al, 2016).…”

Postharvest Treatment with Hydrogen Peroxide to Control Orange Fruit Decay Caused by <i>Penicillum digitatum</i> and <i>Penicillum italicum</i>

“…Because of sticky weather in south China, postharvest rotting and losses of perishable Newhall navel orange grown here are as high as 39%, which is mainly caused by P. digitatum and P. italicum, and are probably the most common postharvest disease of citrus fruits worldwide [1]. The current products used to control green/blue molds worldwide are Imazalil and Thiabendazole chemical based fungicides [2,3]. Long-term use of chemical fungicides in China cause pathogen resistance problem, accompanied by fungicide doses increasing and excess of fungicides residues on fruits [4].…”
