Doan Trang,  *a Phan Khiet Suong,a Duong Van Thiet,c  \nNguyen Quang Tung,a Ha Thi-Dung, b Vu Phuong Lan, b Nguyen The Huub and Do Thi Hanhb  \nThis study investigated the properties of bio-based films composed of chitosan (CH) at concentrations of 1.25% and 1.5%, incorporated with various amounts of graphene oxide (GO) (0, 0.5, 1.0, 1.5, and 2.0%), to develop films for fresh plum preservation. The results showed that films containing low concentrations of GO (0.5–1.0%) exhibited high transparency, whereas higher GO content (1.0–2.0%) led to a significant reduction in transparency. The addition of GO increased the surface roughness of the films. It caused noticeable color changes: brightness decreased, the characteristic reddish-yellow hue of pure chitosan was lost, resulting in darker and less vibrant films. Furthermore, the CH–GO films demonstrated relatively good near-UV blocking ability, allowing only visible light in the yellow to red spectrum to pass through. The incorporation of GO slightly reduced the water absorption and solubility, while significantly decreasing the water vapor permeability of the material (by 47 .09–50. 58% compared to the control film) . In terms of mechanical properties, the film containing a low GO concentration (1 . 0%) exhibited a markedly higher tensile strength (increase 1.41 times) and an improved elongation at break (increase 2. 53 times) compared to the control film. Although the antioxidant activity of GO-containing films showed a slight decline, the antibacterial performance was considerably enhanced, particularly against E. coli, with the inhibition zone diameter increasing by 26 .66–35. 84% compared to the control film. Experimental storage of fresh plums showed that the CH–GO film helped maintain fruit freshness and gloss, preventing spoilage for up to 10 days. Additionally, after 10 days, the film reduced weight loss (by 21.60–72. 53% compared to the pure chitosan film group and 16 .10–42. 63% compared to the control group), slowed color changes, stabilized pH, maintained soluble solid content (reducing the loss by up to 10. 54% compared to the control group), and preserved total acidity throughout the storage period. Based on these findings, CH–GO composite films can be considered a promising packaging material for the preservation of fresh produce.  \n1 Introduction  \nFresh fruits contain a large number of compounds bene􀀁cial to human health, including antioxidants, anthocyanins, phenolic compounds, and various vitamins, which help reduce the risk of chronic diseases and promote overall well-being.1 Therefore, fresh fruits are considered one of the essential food groups in the daily diet. In particular, the plum (Prunus salicina Lindl.), belonging to the Rosaceae family, is a fruit with a distinctive 􀀃avor and contains relatively higher levels of valuable bioactive compounds such as anthocyanins, polyphenols, ascorbic acid,  \naInstitute of Technology – HaUI, Hanoi University of Industry, Vietnam.

In addition, due to their rich nutritional composition, plums offer several health bene􀀁ts, including acting asa natural laxative, improving gastric function, enhancing memory and cognitive performance, promoting bone health, and reducing the risk of cardiovascular diseases.5 Moreover, the presence of compone","cbCaieWHrVIU4EtU","https://ap.wps.com/l/cbCaieWHrVIU4EtU","pdf",5904584,24,"English","# Introduction\n## Fresh fruits and health-related compounds\n## Plum production, seasonality, and postharvest losses\n## Existing preservation methods and need for packaging materials","[{\"question\":\"How were the chitosan–graphene oxide films formulated in the study?\",\"answer\":\"The films used chitosan (1.25% and 1.5%) combined with graphene oxide at 0, 0.5, 1.0, 1.5, and 2.0% to create CH–GO composite films for plum preservation.\"},{\"question\":\"What effect did increasing graphene oxide have on film transparency and appearance?\",\"answer\":\"Low GO content (0.5–1.0%) maintained high transparency, whereas higher GO (1.0–2.0%) significantly reduced transparency and caused darker, less vibrant films with brightness decreases.\"},{\"question\":\"How did the CH–GO films perform during fresh plum storage?\",\"answer\":\"The CH–GO film helped maintain fruit freshness and gloss for up to 10 days, reduced weight loss, slowed color changes, stabilized pH, and preserved soluble solid content and total acidity over the storage period.\"}]","Chitosan–graphene oxide films as a promising packaging material for the preservation of fresh plums (Prunus salicina Lindl.) | PDF",1790706140]
