Tea is a popular non-alcoholic beverage that maintains exclusivity as well as mass appeal for respite and relaxation. Tea is fast gaining importance for its health benefits as a nutraceutical. In addition to its global end-use, tea plantations as a whole are undergoing a transition towards mechanization, and agro-technolotgies for farm mechanization have been rationalized. With the advent of biotechnological approaches, management of genetic resources and plant improvement are evolving, both for improving productivity and quality under normal and stress environments. Tea manufacture is also undergoing process of transformation due to the advent of new machines with precise and controlled steps of manufacture. Pre-withering machine is a disruptive concept in tea processing and is highlighted in this book. Various diversified health care products e.g. theaflavins, polyphenols, theanines decaffeinated tea etc. are getting place in the market. Fast teas viz., Ready-to-Drink teas, tea concentrates, instant tea, tea based juices and tea wines are in queue for impacting the markets. In this book, effort has been made to bring together the latest advances on aspects of tea husbandry, physiology, biochemistry, manufacture and biotechnology to give a one stop exposition of status on Tea Technology to the reader.
