摘要
The chemical quality parameters and sensory evaluation of black teas changed with method of plucking. Hand-plucked teas were very rich in their green-leaf biochemical precursors and had higher contents of made-tea quality constituents than shear-plucked teas. The quality deterioration was mainly due to mechanical injury and non-selective plucking with shear-harvesting. However, tea obtained by shear-harvesting from a continuously sheared field over a prolonged period was found to be superior. The use of shears reduced the yield and increased the plucking average with a net decrease in cost of production compared to hand plucking. (C) 1998 Elsevier Science Ltd. All rights reserved.
