Physical and chemical changes during microwave drying of rice

Original language description

Microwave drying of soaked rice was studied and compared with the conventional drying process. Soaked rice was treated in microwave oven at different processing microwave energy levels, initial moisture contents and temperatures. The maximum value of drying rate for conventional hot air drying is up to 50 times lower than the rate observed for microwave drying. Amylographic gelatinisation, and pasting characteristics were used for the evaluation of microwave treatment influence on chemical and physicochemical characteristics of rice, parameters such as damaged and total starch content and water sorption capacity at 70 °C. It was found that microwave treatment did not affect the total starch content in rice, but the damaged starch content increased with the absorbed microwave energy and temperature of treatment, chiefly for the moisture content of 30 % and temperature of 100 °C. Amylographic characteristics and water sorption capacity showed minimal changes resulted from microwave dryi
