“…Microbial safety is one of the most important factors to be considered for the preservation of minimally processed fruits and vegetables [54]. Blueberries provide an excellent source of nutrients for microorganism growth because they are high in water, starch, and vitamins [55,56]. Figure 5 shows the effect of different treatments on the total viable counts of blueberries during storage.…”

Blueberries are a rich source of health-promoting compounds such as vitamins and anthocyanins and show a high antioxidant capacity. Thus, considerable commercial and scientific interest exists in prolonging its postharvest life to meet the year-round demand for this fruit. In this investigation, the effect of a chitosan-based edible coating, as well as a chitosan-based edible coating containing nanosized titanium dioxide particles (CTS-TiO2), on the postharvest quality of blueberry fruit quality was evaluated during storage at 0 °C. The blueberries were treated with a chitosan coating (CTS) and a CTS-TiO2 composite, respectively. The most suitable chitosan and nano-TiO2 fraction concentrations to be incorporated in the coating formulation were prepared based on the wettability of the corresponding coating solutions. Changes in firmness, total soluble solids (TSS), titratable acidity (TA), ascorbic acid (VC), malondialdehyde (MDA), polyphenol oxidase (PPO), and peroxidase (POD) activities, anthocyanins, flavonoids, total phenolic content, and microbiological analysis were measured and compared. This combined treatment prevented product corruption. Compared with CTS, the CTS-TiO2 composite coating application effectively slowed down the decrease in firmness, TSS, VC, and TA in the blueberries. Additionally, changes in the total polyphenol, anthocyanin, and flavonoid contents and the antioxidant capacity of CTS-TiO2 composite coating blueberry fruits were delayed. Therefore, these results indicated that the chitosan/nano-TiO2 composite coating could maintain the nutrient composition of blueberries while playing a significant role in preserving the quality of fruit at 0 °C.

The influence of novel nano membranes on the quality characterizes of cucumber fruits during storage was evaluated. Chitosan (C), Titanium dioxide nanoparticles (T), and sodium tripolyphosphate (S) were used for the synthesis of novel nano membranes. Samples were divided into four lots. One lot was coated with water; another with C-Film, another with C/T-Film, and the fourth lot with C/T/S-Film. All the samples were dried with forced air at 25 °C for 1 h. Samples were stored in plastic trays for 21 days and evaluated every 7 days (0, 7, 14, and 21 days) at 10 °C. Quality characterizes included texture-profile analysis, pitting and warts appearances rates, acidity, pyruvate enzyme oxidation, and microbial population, especially psychrophilic bacteria. Results revealed that the C/T-Film treated cucumber samples showed the lowest values loss in almost all the texture analysis, gumminess (N) 441.79, resilience 0.035, hardness (N) 1145.02, and cohesiveness 0.19, compared to other coating treatments; while cucumber samples treated with (C/T/S-Film) established the lowest values loss in chewiness (N) 231.41. Cucumber samples treated with C/T/S-Film showed the lower value of pitting and appearance rates 0.67 and 0.21, respectively. For cucumber samples treated with C/T-Film and C/T/S-Film reported the same acidity values as 4.63 at the end of the storage period. The pyruvate enzyme oxidation was higher (187.53 n mol/kg FW) in cucumber fruits treated with C/T/S-Film, compared with cucumber treated with C/T-Film that recorded value of 166.09 n mol/kg FW. After 21 days of the storage period, C/T/S-Film-coated samples had the least psychrophilic bacterial counts 7.03 Log CFU/g, lower than C/T-Film-coated samples 7.6 Log CFU/g. So, in the current work novel nano membranes, consisting of chitosan, titanium dioxide nanoparticles, and sodium tripolyphosphate were effective to extend the shelf-life of cucumbers until 21 days during storage.
