Development of an antimicrobial photodynamic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) packaging film for food preservation

Selenium nanoparticles–enhanced potato starch film for active food packaging application

“…The release of starch films constituents was higher when they were placed in hydrophilic simulants as compared to lipophilic food simulant. The different degree of constituents' migration into the studied simulants could be due to differences in solubility, polarity and interaction between SeNPs, potato starch polymer and food simulant (Kuorwel et al ., 2013; Narasagoudr et al ., 2020; Le et al ., 2021). General, the migration of film constituents was below the Overall Migration Limit (OML) of 10 mg dm −2 stipulated by Regulation EU No 10/201.…”

“…Microbiological safety and quality of food is generally achieved through prevention of contamination during food processing or reduction of food contaminants to acceptable levels using thermal methods and/ or addition of chemicals (Le et al ., 2021; Glicerina et al ., 2021; Nizam et al ., 2021; Wu et al ., 2021). However, preservation approaches that are more reliant on the addition of chemicals in food as preservatives may have detrimental effects on human health such as neurological damage, hypersensitivity, allergy and cancer (de Souza et al ., 2020; Le et al ., 2021; Mousavi et al ., 2021). Therefore, there is a need for finding alternative and effective food preservation methods.…”

Antimicrobial activities of flavedo peel extract and its feasibility in the development of bio‐based pectin coating film for fruit preservation

“…Similarly, the Gly‐Pectin spectrum was not found to differ from the pectin spectrum. It suggested that PFE and glycerol were probably dispersed and allocated within the pectin molecular matrix via physical adsorption as a result of hydrophilic interaction rather than chemical interaction (Le et al, 2021; Lee, Woo, Ahn, & Je, 2014; Sun et al, 2017). The FT‐IR spectra of pectin film incorporated with bioactive compounds from the mulberry leaf extract, which were similar to the original pectin spectrum, did not appear any new peaks or peaks shifting.…”

“…A rectangular film was prepared with a length of 30 mm and a width of 10 mm. The film sample was positioned in the tensile grips and the tension test was performed at the rate of 1 mm/min until occurring the breakage (Le et al, 2021). The TS and EAB values were calculated as followed: where F max is the maximum force ( N ) before the film is ruptured, A is the cross‐section are of the sample film.…”

“…leaf extract showed a delay in banana deterioration during storage for 4 days compared to that without coating (Nguyen et al, 2020). Aloe emodin conjugated poly (3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) packaging film, a light‐activated packaging film, could eradicate 4.7 ± 0.2 log population of Escherichia coli when it was exposed to a blue LED light source at a radiant fluence of 21.6 J/cm 2 (Le et al, 2021). A blend film of carboxymethyl cellulose and Zataria multiflora essential oil showed the potential in antioxidant and antibacterial activities (Dashipour et al, 2015).…”
