The invention belongs to the technical field of health-care tea science, and relates to a novel
ampelopsis grossedentata product and a manufacturing method thereof. The method is characterized by carrying out spread-cooling, de-enzyming, spread-cooling, twisting, deblocking, initial
drying, secondary spread-cooling, twisting and forming, secondary
drying, spread-cooling, drum-
roasting, storage of semi-finished products,
drying, grading, packaging and the like on the picked fresh
ampelopsis grossedentata stem leaves, thus producing the bead-shaped
ampelopsis grossedentata. Compared with the prior art, bitter materials in the
ampelopsis grossedentata product can be reduced because carbureted
hydrogen can be effectively removed by low-temperature, high-temperature and alternating treatment, and rime, stems and green taste on the traditionally processed
ampelopsis grossedentata do not exist due to the utilized mechanical stem separation and grading stem-removal technology. The
ampelopsis grossedentata processed by the novel technology is blackish green (like
green tea), is in a tight and bent shape, and has bright liquor color and
sweet flavor. The
active ingredient of ampelopsis grossedentata has high
flavones content (25%-40%). The technology provided by the invention is applicable to modern tea mechanical
processing, can be used for batched production and meets market requirements.
