“…Some authors have previously reported that the problem of incorporating lipids into a hydrocolloid in a homogeneous way has still to be solved (Bertan et al 2005). The presence of the white spots or linings on the film surface suggests heterogeneity and this seems to be in line with what other authors have previously reported that the appearance of a white spot suggests some heterogeneity in the chitosan matrix when gallic acid was incorporated (Sun et al 2014). …”

“…This reduction can be attributed to the formation of cross-linkages induced by the gallic acid resulting into a more compact film structure restricting water movement. A number of authors have also reported reductions in water vapour permeability after chemical treatments with various cross linking chemical agents (Sun et al 2014;Rivero et al 2010;Hernandez-Munoz et al 2004;Carvalho and Grosso 2004;Carvalho et al 2008;Chiou et al 2008;Pires et al 2013). However, when oleic acid in different concentrations was introduced into the gallic acid treated films, there was an increase in water vapour permeability (Fig.…”

In this study, the effect of gallic acid on mechanical and water barrier properties of zein-oleic acid 0-4 % composite films was investigated. Molecular weight distribution analysis was carried out to confirm gallic acid induced cross linking through change in molecular weight in fraction containing zein proteins. Results revealed that gallic acid treatment increased tensile strength from 17.9 MPa to 26.0 MPa, decreased water vapour permeability from 0.60 (g mm m, increased solubility from 6.3 % to 10.2 % and marginally increased elongation at break from 3.7 % to 4.2 % in zein films only. However, gallic acid treatment in zein-oleic composite films did not significantly influence mechanical and water barrier properties and in most instances irrespective of oleic acid concentration, the properties were negatively affected. Results from scanning electron microscopy showed that both gallic acid treated and untreated zein films and composite films containing 3 % oleic acid had a compact and homogeneous structure while those containing 4 % oleic acid had inhomogeneous structure. The findings have demonstrated that gallic acid treatment can significantly improve mechanical and water barrier properties especially in zein films only as opposed to when used in composite films using zein and oleic acid.

“…In the spectra of Mparticle/FA, Nparticle/FA, and Mcapsule/FA, the appearance of a new peak at 1596-1529 cm −1 was detected. It corresponded to the characteristic band of the C=C from the FA aromatic ring, which indicated its immobilization in the matrices (Sun, Wang, Kadouh, & Zhou, 2014). Also, a frequency shift and a decreased intensity of the peaks corresponding to CS and TPP were observed, compared with the spectra of the matrices without FA, indicating an ionic interaction between the CS-TPP and a possible ionic interaction between the carboxyl group of the FA with the CS amino groups.…”

(2017) Preparation of chitosan matrices with ferulic acid: physicochemical characterization and relationship on the growth of Aspergillusparasiticus, CyTA -Journal of Food, 15:1, 65-74, DOI: 10.1080/19476337.2016 To link to this article: https://doi.org/10. 1080/19476337.2016 Antioxidant, anticarcinogenic, and antimicrobial properties have been reported for ferulic acid (FA), therefore, its application interests both food and agriculture research. FA was immobilized in different chitosan (CS) matrices, physicochemicaly characterized and the effect on Aspergillus parasiticus ecological parameters evaluated. Nanoparticles (Nparticles), microparticles (Mparticles) and microcapsules (Mcapsules) of 35-40 nm, 30-40 μm, and 20 μm, respectively were obtained; FA incorporation in matrices affected their morphology, physicochemical properties, and their fungistatic effect. The effect of the particles was dependent on the matrix exposed. Nparticles and Mparticles showed high FA immobilization efficiency as well as a good fungistatic effect against A. parasiticus: Radial growth at 168 h was 28.46 ± 1.01 and 28.84 ± 1.36 and the inhibition of spore germination at 30 h was 57.44 ± 0.22 and 55.74 ± 2.19, for Nparticles and Mparticles, respectively compared with control cultures. Abnormalities in mycelium, hyphae, and spores morphology were observed, as well as low sporulation due particle interaction with the fungus.Preparación de matrices de quitosano con ácido ferúlico: Caracterización físicoquímica y su relación en el crecimiento de Aspergillus parasiticus RESUMEN El ácido ferúlico (AF) presenta propiedades antioxidantes, anticancerígenas y antimicrobianas, siendo de interés para su aplicación en alimentos y agrícultura. El AF fue inmovilizado en diferentes matrices de quitosano, se caracterizó fisicoquímicamente y se evaluó su efecto sobre Aspergillus parasiticus. Se obtuvierón nanopartículas, micropartículas y microcápsulas de 35-40 nm, 30-40 µm y 20 µm, respectivamente. La incorporación de AF en matrices afecto su morfología, propiedades fisicoquímicas y su efecto fungistático, dependiendo de la matriz expuesta. Las nano y micropartículas mostraron gran eficiencia de inmovilización de AF y efecto fungistático sobre el hongo: inhibición de crecimiento radial a 168 h de 28,46±1,01 y 28,84±1,36 y de germinación de esporas en 30 h de 57,44±0,22 y 55,74±2,19, respectivamente. Asimismo se observaron anomalidades en micelio y morfología de hifas y esporas, así como baja esporulación, debido a la interacción entre las partículas con el hongo. Las microcápsulas no ejercieron efecto antifúngico, sin embargo, tanto las nano-como las micro-partículas son buenos candidatos para el control de hongos.

“…In this respect, gallic acid (GA) (3,4,5-trihydroxybenzoic acid) is a phenolic acid, widely distributed among the plant kingdom, showed a promising potential for inclusion in chitosan matrix since it proved antioxidants and antimicrobial activities (Yen et al 2002;Chanwitheesuk et al 2007). It was also reported that the incorporation of GA into the chitosan matrix not only improved the elasticity and physical properties of chitosan film (Hager et al 2012;Sun et al 2014) but also increased the hydroxyl radical scavenging capacity of the produced films (Pasanphan et al 2010). Accordingly, it is hypothesized that the use of chitosan in conjunction with GA would be beneficial for fruit preservation.…”

“…Postharvest dipping of 'Embul' bananas in 1% chitosan (Jinasena et al 2011) or 'Cavendish' bananas in 2% chitosan (Suseno et al 2014) delayed ripening, decreased weight loss and maintained higher firmness and vitamin C concentration with lower anthracnose incidence than control. In addition to its function as protective barrier, chitosan coating can work as carrier for bioactive compounds, such as antioxidants and antimicrobials (Sun et al 2014). In this respect, gallic acid (GA) (3,4,5-trihydroxybenzoic acid) is a phenolic acid, widely distributed among the plant kingdom, showed a promising potential for inclusion in chitosan matrix since it proved antioxidants and antimicrobial activities (Yen et al 2002;Chanwitheesuk et al 2007).…”

The effect of postharvest chitosan, gallic acid (GA) and chitosan gallate (CG) dipping treatments at different concentrations on quality parameters, antioxidant compounds, free radical scavenging capacity (FRSC) and enzymes activities of 'Sukkari' bananas were studied during storage (ripening) at 20 ± 2°C and 60-70% RH for 13 days. Weight loss and peel color index (the change from green to yellow) increased while, membrane stability index of peel tissues, pulp firmness and acidity decreased during storage. CG and GA treatments slowed down the changes in these parameters compared to control. Total soluble solids (TSS) concentration increased during storage and was lower at CG than other treatments. TSS/acid ratio increased during storage and showed higher value after storage than initial. This ratio was lower at 1% chitosan, 0.075% GA and CG treatments than control. Both vitamin C and total flavonoids concentrations decreased during storage and were not affected by the applied treatments. Total phenols concentration decreased during storage and was higher at acetic acid and the high rate of chitosan, GA and CG treatments than control. FRSC (DPPH IC 50 values) of fruit peel ranged from 2.54 to 4.19 lg phenolics concentration among the treatments. FRSC was not affected by the applied treatments but increased (lower IC 50 value) during shelf life. The possible relations of these biochemical changes with the activities of the enzymes a-amylase, xylanase, polygalacturonase, peroxidase and polyphenoloxidase were discussed. It is concluded that postharvest CG and GA treatments delayed ripening and maintained better quality parameters of 'Sukkari' bananas during 13 days of shelf life than control.
