Cucumber (Cucumis sativus) is an economically important vegetable worldwide.Cucumbers have short shelf life with sensitivity to chilling injuries and fungal and bacterial postharvest diseases. Prosopis juliflora water-soluble leaf ethanolic (PJ-WS-LE) extract has a strong antimicrobial activity against many spoiling agents with time-stability and no phytotoxicity on fruits. The present study explores PJ-WS-LE extract efficacy as a coating material to preserve cucumber. 8 mg/ml of PJ-WS-LE extract increased cucumber shelf life at 22°C by 77%. At week 2, cucumber coated with PJ-WS-LE extract alone showed less than 10 CFU/g of mold as well as 76.9% and 85.8% reduction of total yeast and aerobic bacterial counts, respectively. PJ-WS-LE extract treated samples maintained the slightest change in total soluble solids and 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity. Embedding PJ-WS-LE extract in 0.5% chitosan did not improve the quality maintaining results. In vivo overall results highlight the potentials of PJ-WS-LE extract as a possible coating replacement of chemical fungicides. Novelty impact statement:• Prosopis juliflora water-soluable leaf ethanolic (PJ-WS-LE) extract extended cucumbers shelf life at 22°C by 77%.• PJ-WS-LE extract served as an antimicrobial agent that lowers surrounding bacterial and fungal counts of coated cucumber samples.• 8 mg/ml of Prosopis juliflora water-soluble leaf ethanolic maintained cucumbers storage quality-parameters up to three weeks at 8°C.

“…The smallest RMSE was calculated as 0.0012 in the "Diffusion approach" model, in the 30h70Bx trial (Table 5). Shahari et al [38] carried out a study on the mathematical modeling of cucumber drying, which is also from the same family as bitter gourd, at a drying air temperature of 50 • C. In the study, the "Newton", "Page", "Modified Page", "Henderson and Pabis", "Logarithmic", "Wang and Singh", and "Midilli et al" models were tested, and the most suitable model was chosen, since the "Logarithmic" model gave the highest R 2 , lowest RMSE, and SSE (sum of square error) values. da Cunha et al [39] dried the melon at 60 • C drying air temperature by applying four different pre-treatments as dipping, dipping with ultrasound, with vacuum and with ultrasound and vacuum.…”

A significant vegetable in the Cucurbitaceae family, the bitter gourd (Momordica charantia L.) is widely recognized for its beneficial health properties, including anti-diabetic, anti-carcinogenic, anti-inflammatory, anti-ulcer, antiviral activities. With a total of three Brix values (50, 60, and 70) and three different dipping times (10, 20, and 30 h), the goal of the current study was to identify the proper sugar and grape molasses solutions (pekmez) and dipping times for osmotic pre-treatments of bitter gourd samples to make it sweet and widely consumed. In the present study, mathematical modeling of drying processes, moisture content and water activity, total color changes, total phenolic content-antioxidant activity, and carotenoid contents were assessed. As a result of 13 different mathematical modeling tests, “Diffusion Approach”, “Logarithmic” and “Midilli et al.” models were the best models, giving the highest R2 and lowest X2-RMSE values. There were samples that were dipped at 50 °Brix grape molasses, which decreased below the 10% wet basis (w.b.) limit in the shortest time with 180 min, in a 10 h dipping time. The samples were dipped in 60 °Brix sugar, which fell below the same limit in the shortest time with 135 and 165 min, respectively, at 20 and 30 h dipping times. The highest total phenolic and carotenoid contents were found in 30 h dipping time in 60 °Brix grape molasses with 8296.87 mg/kg and 10 h dipping time in 50 °Brix sugar solutions with 89.22 mg/kg, respectively. While the phenolic content was higher in all samples dipped in grape molasses, the carotenoid content was higher in all samples dipped in sugar, which was one of the most important results of the study.

“…Consequently, an efficient drying system and proper equipment can be manufactured. Thus far, several researchers have used mathematical drying models for food and agricultural products [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Unfortunately, investigations on the drying kinetics of cellulose-based RCMs have not been addressed in depth, although the bio-based product has recently become a primary concern worldwide.…”

Drying Regimes on Regenerated Cellulose Films Characteristics and Properties

Abundant water content and its interaction with cellulose macromolecules through hydrogen bonding engenders a complex drying process, the circumstances of which have not yet been unveiled. For instance, excessive drying on regenerated cellulose membranes (RCM) causes cracking and severe shrinking, affecting the produced regenerated cellulose film (RCF). Thus, mathematical models in estimating the drying kinetics and required energy to dry RCM are necessary. This study evaluated two drying techniques of oven drying and infrared (IR) drying on RCM at different temperatures of 50–80 °C. Five mathematical models were used, namely Newton, Page, Handreson–Pabis, logarithmic, and Wang–Singh, to adjust the obtained experimental data and were statistically validated using ANOVA to review their effect on the quality of the produced RCF. A logarithmic model and a Wang–Singh model were the best models for oven drying and IR drying of RCM, respectively. It was found that the physical property of the RCF was similar to all drying types. Meanwhile, for mechanical properties, the high temperature of oven drying affected the tensile properties of RCF compared with IR drying. This study is beneficial by approximating the drying kinetics of RCM and defining appropriate drying conditions, which controls the quality of its predictive physical and mechanical properties.
