This study was carried out to establish the manufacturing process of barley leaf powder tea. The optimal manufacturing process among many trials was determined with sensory evaluation. Finally established process and operation conditions were as follows: pretreatment (cutting and washing), steaming (, 30 sec), primary drying and roasting (, 40 min), rolling (RT, 25 min), middle drying and roasting (, 30 min), final drying and roasting (, 25 min), drying (, 20 min), roasting (, 20 min), and powdering (120 mesh). The barley leaf powder tea produced by this process mainly consisted of dietary fiber (33.8%), amino acids (12.9%), minerals (4.7%) and (6.9 mg%). |
