초록

A process for manufacturing a fast infusing black leaf tea. The process involves (a) withering tea leaves to a moisture content between 64 and 70%, (b) macerating the withered leaves tea leaves by the controlled application of both shear and compression forces sufficient to disrupt the majority of cells within the tea leaf, to introduce morphological changes in the tissue and to redistribute the cell contents, (c) fermentating the resulting dhool, (d) firing the leaves to arrest the fermentation and (e) drying and sorting the fired leaves to give black ...

The invention claimed is: 1. A process for manufacturing larger leaf black tea comprising the steps of withering and macerating tea leaves modified to deliver increased shear and compression, allowing them to ferment, firing the leaves to arrest fermentation and then drying and sorting them to yield black leaf tea, the process being characterised in that the tea leaves are withered to a moisture content of between 64% and 70% before being macerated by the controlled application of both shear and compression forces sufficient to disrupt the majority of c...
