Abstract: Objective To explore the rapid drying method of barley seedling powder. Methods The drying process of barley seedling powder was studied by hot air drying and microwave drying equipment. The effects of hot air temperature, microwave power and water cut rate on the content of chlorophyll and total flavonoids in the drying process were investigated.
Results The optimum combined drying conditions were: hot air temperature 66.2 °C, microwave power 231 W, conversion point moisture content 50.91%, the chlorophyll content was (6.006±0.192) mg/g, and the relative error with the theoretical prediction was -0.77%; the content of total flavonoids was (5.695 ± 0.145) mg / g, and the relative error from the theoretical prediction was -1.18%. Compared with hot air drying, the nutrient content of the combined dried barley powder increased by 3.69% and 13.04%, respectively, and the drying time was shortened by 22%. Conclusion Combined drying with hot air and microwave is a better method for drying barley seed powder, which provides a scientific reference for the drying process of barley seed powder.
