“…The addition of TPP resulted in cross-linking the CTS nanoparticles in the form of coagulation, which was continued by stirring the nanocarriers overnight and then rinsing with distilled water to remove unreacted material in the supernatant. Then, the nanocarriers that were prepared by freeze-drying were dried using a vacuum pump [35].…”

Edible coatings are an appropriate way to preserve the quality of horticultural crops and reduce post-harvest losses. In this study, treatments with proline (Pro), chitosan (CTS) and proline-coated chitosan nanoparticles (CTS-Pro NPs) to maintain quality and reduce the decay of strawberry fruit were examined during storage at 4 °C for 12 days. The strawberries were treated with Pro 1 and 5 mM, CTS at 0.1% (w/v), CTS-Pro NPs at 0.1% (w/v) and distilled water (control) at 20 °C for 5 min. Following 3, 6, 9 and 12 days of cold storage, the fruits were removed from refrigeration, and some traits were evaluated one day after storage under shelf-life conditions. The results indicated that the fruit coated with CTS and CTS-Pro NPs showed reduced malondialdehyde and hydrogen peroxide content and less decay and weight loss compared to control and proline. CTS-Pro NPs also preserved fruit quality by conserving higher levels of ascorbic acid, total soluble solids, total phenolic content, and antioxidant capacity and enzymes. These results confirmed the benefit of using chitosan and CTS-Pro NP coatings to maintain fruit quality and increase the shelf life of strawberries by enhancing their antioxidant system and their ability to eliminate free radicals under cold storage.

“…Further, 20 containers were kept in the refrigerator for cold storage (5°C) and 20 containers were kept in a controlled environment chamber for ambient storage (23°C/50 ± 5% RH). Then after, one container from each storage was removed from storage in 2 days interval and analyzed for different physicochemical parameters for 20 days (Mahmoudi et al, 2022). Weights and color indices of coated and uncoated plums on day 0 were used to calculate weight loss and color change during storage (Muley & Singhal, 2020).…”

The present investigation applied a new coating (taro starch‐casein composite enriched with micellar pomegranate peel extract (MPPE)) to mature plum (Prunus salicina L.) fruits in a randomized factorial design with five replicates. Results showed that, during storage of 20 days at 5 and 23°C, a recognizable reduction in weight and firmness loss with a stable respiration rate of coated plums than uncoated ones (4.5% and 8.4% at 5 and 23°C respectively) were noticed. The coating provided appealing optical properties with exceptionally controlled changes in pH and acidity of plums. The coating significantly reduced the change in total soluble solids (TSS) at the end of storage which was 9 and 11.67°brix compared to uncoated fruits (11.83 and 13.08°brix) at 5°C and 23°C, respectively. Moreover, the loss of bioactives (polyphenols, flavonoids, antioxidant capacity, and ascorbic acid) was arrested due to bioactive coating. A slight rise in total anthocyanins, carotenoids, and reducing sugars was observed at 23°C. However, they were efficiently suppressed in coated fruits stored at 5°C. Microbial growth was also effectively controlled in coated plum fruits. Overall, the results suggested that applying MPPE starch‐casein composite coating on plum fruits exhibited a noticeable shelf life of ≥20 and 14 days at 5 and 23°C, respectively, over uncoated fruits (about 12 and 8 days). Novelty impact statement Plum fruit is a nutritionally rich climacteric fruit. However, it is very prone to deterioration and thus a quick loss in its quality. Many postharvest practices, such as irradiation, controlled and modified atmosphere storage, and chemical and thermal treatment have been used. However, these methods affect the nutritional value of fruits. The biodegradable bioactive coating is one of the cost‐effective ways for the shelf‐life extension of fruits. In this regard, natural bioactive and antioxidant‐rich MPPE enriched starch‐casein composite acts as a barrier against moisture loss and gas exchange and provides a glossy appearance to the fruits. Moreover, the bioactive coating provides excellent pathogen resistance with effective retention of bioactive compounds. Using the finding of this study, the application of MPPE enriched starch‐casein composite coating to plum fruits stored at ambient (23°C) and cold (5°C) storage can extend the postharvest shelf‐life of plum, save cost and energy, and open the global marketing window for plum fruits. MPPE‐taro starch‐casein composite coating was successfully used to prolong the postharvest life of plum fruits as well as to minimize fruit processing industrial waste by utilizing pomegranate peel as a source of a bioactive ingredient. Physical (color, firmness, and weight loss), chemical (pH, acidity, and TSS), and bioactive (polyphenols, ascorbic acid, carotenoids, and anthocyanins) properties of plums were found to be retained with the application of coatings during storage. The composite coating containing natural bioactive compounds can be used as an effective alternative to ...

“…Furthermore, the foliar application of Cs-Se NPs remarkably increased proline content in bitter melon under salt stress [39]. Mahmoudi et al [40] reported that CTS-GB NPs treatment (0.5%) enhanced proline content in plum fruit during storage at 1 °C for 40 days. Accordingly, it can be deduced that the application of CTS-Arg NPs at 0.5% to plum fruit had an effective role in controlling chilling injury by increasing the content of proline.…”

“…The following treatments were applied as 10-min dips at 25 °C: control (distilled water), Arg at two concentrations (0.25 and 0.5 mM), CTS at 1% and Arg-CTS nanoparticles (CTS-Arg NPs) at two concentrations (0.5 and 1%, w/v). All nanomaterials were synthesized at laboratory of Nanochemsitry, University of Maragheh, Maragheh, Iran according to Nasr et al [31] and Mahmoudi et al [40]. A scanning electron microscope (SEM, VEGAII, XMU, Czech Republic) and transmission electron microscope (TEM; Philips CM10) was used to examine the surface morphology and the size of CTS-Arg NPs.…”

Background Plum (Prunus domestica L.) has a short shelf-life period due to its high respiration rate and is sensitive to low storage temperatures, which can lead to the appearance of chilling injury symptoms. In this investigation, we applied new coating treatments based on chitosan (CTS) and arginine (Arg) to plum fruit (cv. ‘Stanley’). Results Fruit were treated with distilled water (control), Arg at 0.25 and 0.5 mM, CTS at 1% (w/v) or Arg-coated CTS nanoparticles (CTS-Arg NPs) at 0.5 and 1% (w/v), and then stored at 1 °C for days. The application of CTS-Arg NPs at 0.5% attenuated chilling injury, which was accompanied by accumulation of proline, reduced levels of electrolyte leakage and malondialdehyde, as well as suppressed the activity of polyphenol oxidase. Plums coated with CTS-Arg NPs (0.5%) showed higher accumulation of phenols, flavonoids and anthocyanins, due to the higher activity of phenylalanine ammonia-lyase, which in turn resulted in higher DPPH scavenging capacity. In addition, CTS-Arg NPs (0.5%) treatment delayed plum weight loss and retained fruit firmness and ascorbic acid content in comparison to control fruit. Furthermore, plums treated with CTS-Arg NPs exhibited lower H2O2 accumulation than control fruit due to higher activity of antioxidant enzymes, including CAT, POD, APX and SOD. Conclusions The present findings show that CTS-Arg NPs (0.5%) were the most effective treatment in delaying chilling injury and prolonging the shelf life of plum fruit.
