About the book
This book will discuss various aspects of the health benefits of Tea (Camellia sinensis). The introductory part should present different types of tea (green tea, black tea, oolong tea, yellow tea, white tea etc.), manufacturing process, and its consumption as a beverage and in other forms which attribute to the wellness and health. Beneficiary chemical constituents of tea will also be covered, followed by the discussion on antioxidant properties of these constituents. Tea contains highest polyphenolic constituents in addition to substantial quantities of flavonoids, theanine, polysaccharides, and other bioactive compounds.
Additionally, authors are expected to cover the medicinal effect of tea polyphenols viz. catechins, theaflavins and thearubigins which are the major chemical compounds of tea. Green tea contains a higher quantity of catechins as compared to black tea which becomes transformed into more complex compounds (theaflavins and therubigins) during the manufacturing of black tea. Out of many therapeutic uses these bioactive compounds, protection against cardiovascular diseases, atherosclerosis, cancer, gene mutation, and diabetics have been reported and are more promising. This book will also highlight the nutraceuticals of tea. The catechins along with other various bioactive compounds present in tea have many therapeutic properties which attribute to the development of various food products where tea constitutes as an active ingredient. That is why it is important to stress the potential use of tea and their bioactive constituents (catechins, polysaccharides, vitamins, amino acids etc.) in food products with added nutraceutical values. Finally, the contamination of tea and its effect on our health will also be covered. Tea and its food products may contain various types of contaminations which may include toxic heavy metals, pesticides, microorganisms, and environmental pollutants etc. which are present from tea infusion and from residues. These contaminations which are above the regulatory limit may pose a serious threat to public health. Submitted chapters are expected to contain novel information, be informative as well as thought-provoking.
