Modification in cellulose films through ascent cold plasma treatment and polymerization for food products packaging

Effect of dielectric barrier discharge cold plasma on the bio-nanocomposite film and its potential to preserve the quality of strawberry under modified atmosphere packaging

“…It seems cold plasma caused intense hydrogen continuity water to chitosan and nanoparticles (Oberlintner et al, 2022). On the contrary, in the second stage, the weight loss happened dramatically which corresponds to the rapid volatilization of chitosan chains due to the division of glycosidic connections (Oberlintner et al, 2022;Ranjha et al, 2023). However, the slope of the trend in the third stage revealed the positive effect of the DBD treatment on the thermal stability of films, even though, the time treatment did not affect the TGA results.…”

“…From the pre-tests, a distance of 3-8 cm was considered to control the uniformity of plasma distribution, and the best performance was observed at a distance of 5 cm (Figure2.b). Additionally, the duration of treatment is critical parameters impacting system's performance (Ranjha et al, 2023). As a result, three different treatment times, namely 5, 10, and 15 minutes were taken into account.…”

“…Also, hydrogen linkage between bacterial cellulose and chitosan probably formed a more arranged structure. This arrangement creates a difficult situation for molecules of gas to diffuse hence the oxygen barrier characteristic was stronger (Ranjha et al, 2023). Also, the plasma treatment affected the higher molecular weights of chitosan which tended to self-accumulate naturally.…”

“…The film was treated under power 100 W for 60-90 s and increasing of the tensile strength was reported. Further, Wu et al (2020), Goiana et al (2022) and Ranjha et al (2023) approved the application of DBD for the improvement of the bio-Nano composite films. Nevertheless, limited studies have been researched regarding the effect of dielectric barrier discharge cold plasma on bio nanocomposite based on chitosan-cellulose and its utilization for preservation of fresh and perishable fruit under actual storage condition.…”

“…Appropriate packaging plays a key role in the maintenance and extension of fresh fruit and vegetables shelf life. The application of packaging material to minimize the respiration rate, produced ethylene, spoilage rate and microbial activities of fresh fruit and vegetables is essential from the perspective of researchers in the packaging industry (Ceylan and Atasoy, 2023;Ranjha et al, 2023). However, overcoming the environmental problems due to the carbon dioxide released from the packaging material still is a challenge.…”
