“…SEM was performed to characterize the microscopic morphology of AGO. Figure 1 a shows that AGO was stacked together to form a multilayer sheet structure, which is consistent with the reported of Ramanathan et al [ 20 , 21 , 22 ]. Compared with GO, Figure 1 b shows TEM images, further showing a transparent yarn-like structure with fewer wrinkles and smoother surface of AGO [ 15 , 20 ].…”

Compared with GO, Figure 1 b shows TEM images, further showing a transparent yarn-like structure with fewer wrinkles and smoother surface of AGO [ 15 , 20 ]. It was attributed to the partial reduction of GO by EDA and the interaction between the AGO plates, which together led to decrimping and blurring of the edges [ 14 , 15 , 23 ].…”

“…The total soluble solid (TSS) content of cherry tomatoes was determined using an AR 2008 Abbe refractometer (Kruess, Hamburg, Germany). A drop of clear tomato juice obtained by squeezing the fruit in a muslin cloth was placed in the reading chamber, and the value of TSS was read (%) [ 20 ].…”

The shelf life of cherry tomatoes is short so that new and efficient preservation techniques or procedures are required to reduce postharvest losses. This study focused on the development of a sulfonated poly ether ether ketone (SPEEK) film incorporated with amidated graphene oxide (AGO), for the storage of cherry tomatoes in modified atmosphere packaging. The mechanical properties, gas permeability, and moisture permeability were subsequently tested. The evolution of attributes related to shelf life, such as gas composition, physicochemical properties, and sensory properties were also monitored during storage trials. AGO, as an inorganic filler, increases the thermal stability and mechanical properties of SPEEK-based films, while it reduces the water absorption, swelling rate, and moisture permeability. Importantly, all the AGO/SPEEK films exhibited enhanced gas permeability and selective permeability of CO2/O2 relative to the SPEEK film. Moreover, 0.9% (w/w) AGO/SPEEK film showed an enhanced permeability coefficient of CO2, corresponding to an increase of 50.7%. It could further improve the selective coefficient of CO2/O2 to 67.1%. The results of preservation at 8 °C revealed that: 0.9% (w/w) AGO/SPEEK film was significantly effective at maintaining the quality and extending the shelf life of cherry tomatoes from 15 to 30 days, thereby suggesting the potential for applying AGO-incorporated SPEEK films for food packaging materials.

“…The colour of tomatoes evaluated in the L* a* b* system is presented in Table 3. During the 15-day storage at 12 ± 1 °C, a decrease in the value of the L* parameter was observed, which is a naturally occurring process in tomatoes and has been verified by several studies conducted by, inter alia, Chen et al [57] and Boonsiriwit et al [58]. During storage, the a* parameter increased and the b* parameter decreased in all groups of tomatoes, regardless of the time of ozonisation and gas concentration.…”

The impact of ozone concentration and ozonisation time on the selected chemical, physical and microbiological properties of Rapanui tomatoes was investigated. Tomatoes were exposed to gaseous ozone at concentrations of 0.9 and 2.5 mg L−1 (c1, c2) for 30 and 120 min (t1, t2), and stored for up to 15 days at a temperature of 12 ± 1 °C. The following parameters were evaluated: titratable acidity, total soluble solids, total phenolic and flavonoid contents, lycopene, total carotenoids, vitamin C, total antioxidant activity, colour L* a* b* and firmness. Ozonated fruit had higher levels of total soluble solids and higher levels of titratable acidity during and after storage. Exposure of tomatoes to a cooling atmosphere, applying recommended ozonisation process parameters, efficiently inactivated microorganisms that are present on the surface and reduced fruit weight loss, while retaining their firmness and stable colour.

“…When they are used to prepare packaging film, they can not only give the packaging film the ability to absorb ethylene but also improve the performance of packaging film 76 . Boonsiriwit et al 63 prepared alkaline halloysite nanotubes (ALK‐HNTs)/low‐density polyethylene film and found that ALK‐HNTs improved the O 2 barrier property of the film. In addition, they can also be packaged in breathable bags and used as ethylene removal devices.…”

Application of ethylene‐regulating packaging in post‐harvest fruits and vegetables storage: A review

Ethylene is a key hormone to promote the ripening of fruits and vegetables (F&V). It is detrimental to the transportation, storage, and sale of F&V. In order to control the maturation of F&V and reduce their losses, many ethylene-regulating packaging (ERP) have been developed. In this review, we first introduced the synthesis pathway of ethylene. Next, we divided ERP into four categories: ethylene-degrading packaging, ethylene-adsorbing packaging, modified atmosphere packaging, and bioactive packaging according to the way of regulating ethylene, clarifying the regulation mechanism and characteristics of various types of packaging. Finally, we predicted the future development direction of ERP.
