摘要

The present invention relates to a manufacturing method of Hoveniea dulcis leaf tea, and Hovenia dulcis leaf tea manufactured thereby. The present invention has a purpose of manufacturing Hovenia dulcis leaf tea which remarkably improves the taste and flavor of the Hovenia dulcis leaves by searching optimal conditions for selecting Hovenia dulcis leaves, the cutting size, the steaming pressure and time, the fixated temperature and time, the rubbing method and time, the drying temperature and time, and the flavor processing temperature and time. To achieve this, the manufacturing method of the present invention comprises: (a) a step of collecting Hovenia dulcis leaves from June to August, and washing and cutting them into 3-5 cm size; (b) a step of steaming the cut Hovenia dulcis leaves at step (a) with steam of 100°C for 10-30 seconds; (c) a step of cooling the steamed Hovenia dulcis leaves at step (b) at room temperature for 5-15 minutes so that the leaf temperature becomes 30-40°C; (d) a step of conducting a rubbing process by rubbing the steamed and cooled Hovenia dulcis leaves of step (c) for 10-15 minutes; (e) a step of conducting a roasting process by roasting the rubbed Hovenia dulcis leaves at step (d) at a temperature of 160-200°C for 10-20 minutes; (f) a step of drying the roasted Hovenia dulcis leaves at step (e) at a temperature of 40-50°C for 8-12 hours so that the moisture content becomes 5-7%; and (g) a step of conducting a flavor processing by roasting the dried Hovenia dulcis leaves of step (f) in a cast iron pot at a temperature of 70-90°C for 15-25 minutes so as to express the characteristic flavors and colors of the Hovenia dulcis leaves.;COPYRIGHT KIPO 2014
