In addition, raising the temperature to 60°C led to a decrease in the mass transfer rate WL/SG and thus a decrease in the quality of the final product. At a temperature of 50°C, the viscosity of the solution with 60% concentration is very high, so that the water loss curves were very close to the water loss curves at 50% concentration, so the best temperature and concentration are at 50°C and 50%, respectively, and the results showed that the ratio of fruits to solution 10:1 is the optimal ratio, and the best duration of the osmotic drying process was 6 hours, The concentration of 60% and the temperature of 30 °C are the optimal conditions for maintaining the high nutritional value, biologically active compounds and antioxidant activity, by forming a layer of sucrose that protects the fruits from deterioration during subsequent manufacturing processes.
