The potential of gum arabic enriched with cinnamon essential oil for improving the qualitative characteristics and storability of guava (Psidium guajava L.) fruit

An Analysis of the Published Literature on the Effects of Edible Coatings Formed by Polysaccharides and Essential Oils on Postharvest Microbial Control and Overall Quality of Fruit

“…Twelve studies used other polysaccharides or gums combined with CH, such as CS (de Aquino et al., ), hydroxypropylmethylcellulose (Sánchez‐González et al., ), and locust bean gum (Aloui et al., ), or as the only ingredient to formulate coatings, such as gum arabic (GA; Andrade et al., ; Etemadipoor, Ramezanian, Mirzaalian Dastjerdi, & Shamili, ; Maqbool et al., ), mesquite gum (Bosquez‐Molina, Jesús, Bautista‐Baños, Verde‐Calvo, & Morales‐López, ), flaxseed gum (Yousuf & Srivastava, ), pullulan (Gniewosz & Synowiec, ), pectin (Guerreiro, Gago, Faleiro, Miguel, & Antunes, ; Rodriguez‐Garcia et al., ), and sodium alginate (Guerreiro et al., ).…”

“…Twenty‐four out of the 30 selected studies used EOs for the formulation of edible coatings, such as the EO from cinnamon (Etemadipoor et al., ; Maqbool et al., ; Xing, Li et al., ; Xing et al., , ), lemongrass (Athayde et al., ; Maqbool et al., ; Oliveira et al., ; Vu et al., ; Yousuf & Srivastava, ), peppermint (de Oliveira et al., ; Guerra et al., , ; Vu et al., ), bergamot (Aloui et al., ; Cháfer et al., ; Sánchez‐González et al., ), oregano (Andrade et al., ; Barreto et al., ; dos Santos et al., ; Rodriguez‐Garcia et al., ; Vu et al., ), rosemary (Andrade et al., ), clove (Shao et al., ), thyme (Bosquez‐Molina et al., ; Cháfer et al., ), tea tree (Cháfer et al., ), Mexican lime (Bosquez‐Molina et al., ), and Lippia gracilis (Azevedo et al., ; de Aquino et al., ). Only five studies used ICs to formulate edible coatings, to cite: carvacrol (de Souza et al., ; Sun et al., ), cinnamaldehyde and trans ‐cinnamaldehyde (Sun et al., ), thymol (Gniewosz & Synowiec, ), citral and eugenol (Guerreiro et al., ), and limonene (Vu et al., ).…”

“…The studies have ordinarily used sub‐MICs of these substances/compounds to formulate the coatings (de Oliveira et al., ; de Souza et al., ; Guerra et al., , ; Oliveira et al., ). Only five studies did not perform in vitro assays to select the concentrations of EOs or ICs used to formulate the coatings (Cháfer et al., ; Etemadipoor et al., ; Perdones et al., ; Xing et al., 2011; Xing et al., ) and two studies used the same concentration in both in vitro and in situ assays (Maqbool et al., ; Rodriguez‐Garcia et al., ), which were selected considering data of previous published studies.…”

“…Hydroxypropylmethylcellulose (1%, w/v) was dissolved in distilled water (80 C for 2 hr) under overnight stirring at room temperature (Sánchez‐González et al., ). Three studies used GA to formulate coatings and this polysaccharide was firstly dissolved in ultra‐purified water and stirred at 40 °C for 60 min (Andrade et al., ; Etemadipoor et al., ; Maqbool et al., ). One study used pullulan or mesquite gum to formulate coatings.…”

“…Tween 20 and 80 are commonly used (17 studies) to homogenize the EOs or ICs into the polysaccharides dispersions (Aloui et al., ; Andrade et al., ; Athayde et al., ; Azevedo et al., ; Barreto et al., ; Cháfer et al., ; de Aquino et al., ; de Oliveira et al., ; Etemadipoor et al., ; Maqbool et al., ; Oliveira et al., ; Shao et al., ; Sun et al., ; Vu et al., ; Xing et al., 2011; Xing et al., , ). Three studies used only vigorous stirring for homogenizing EOs or ICs into the polysaccharides dispersions (Bosquez‐Molina et al., ; Guerra et al., ; Yousuf & Srivastava, ).…”
