“…Gelatin powder was purchased from R&M Chemicals (Malaysia) and three different concentrations of gelatin (10,15, and 20 wt %) were prepared in this study. The gelatin powder was dissolved in distilled water and heated using a hotplate with magnetic stirrer at 45 °C and 500 rpm.…”

“…The process is essential to improve its weak mechanical strength and degradation in vivo as well as modifying the state of molecular interactions between the polymer chains to regulate its physiochemical properties [9]. However, the convective oven has drawbacks such as not being energy-efficient, nonuniform heating, and inferior dried product quality [10]. Although freeze-drying is the preferred option, it also has inherent drawbacks such as prolonged drying time, high maintenance and operating costs [11].…”

Microwave heating was utilized as a dehydration method to produce gelatin membranes. The results demonstrated that the moisture content reduced drastically at higher microwave power, and the effective diffusivities were determined. The specific energy consumption was recorded at a higher range for 10 wt % but an opposite trend was observed for the moisture extraction rate. The spectra of all dehydrated gelatin membranes were quite similar to that of gelatin powder. Microwave dehydration increased the disordered structure of gelatin which enhanced the amphiphilicity. The surface morphology revealed a rough membrane surface which could aid the adhesion and growth of human skin cells.

In recent years, the research in the field of medicinal plants as therapeutic supplements has increased significantly. Lavender extract is widely used among medicinal plant products due to its unique therapeutic properties. Since drying processes require high energy, this study was conducted to study the performance of the spray dryer in the production of lavender extract powder at three levels of air temperature 150°C, 180°C, and 210°C, three levels of compressed air flow rate 6, 8, and 10 L/min and ratios of maltodextrin‐drying aid to the mass of dry matter of the extract 0%, 25%, and 50% by response surface method. For this purpose, the energy efficiency and exergy of the powder production process were examined. According to the obtained results, increasing the inlet air temperature and the inlet air flow rate increased the energy efficiency and exergy and decreased the energy efficiency and exergy, respectively. The energy efficiency of the drying process varied in the range of 6.55%–15.87%, and the exergy efficiency () of the drying process in the range of 2.87%–5.84%. Also, the of the spray dryer was calculated in the range of 20.05%–38.78%. Based on the energy efficiency and exergy, the optimal production of lavender plant extract powder was obtained at the air temperature of 210°C, the compressed air flow rate of 6 L/min, and the amount of drying aid of 11.9 g/L.
