On the molecular consideration of tea antioxidant quality and their shelf life assessment

Abstract

Tea, in brief, can be ascribed as the most popular, cheapest and utility drink after water. newlineWithout any promotional or awareness program for drinking tea, it was popularized newlinelong back and consumption of tea is an age-old habit and two-thirds of the world s newlinepopulation is habituated to consume tea, infused leaves of Camellia sinensis. Though newlinetea had probable an unassertive beginning and its acceptance believed to spread from its newlineorigins in China to entire East Asian country to Western Europe and the Americas. newlineSince long past few decades, scientists have paid an intense interest to the prospective newlinehealth assistances of tea and have revealed that most of the traditional stories about tea newlinemay essentially be true. Tea leaves comprises several naturally occurring newlinephytochemicals, including polyphenols, catechin and their several derivatives are newlineevidenced to have worthy antioxidant properties. Antioxidants are proving to be newlineessential as it neutralizes free radicals (voluntarily evolved during different metabolic newlinefunctions), if remain unattended in cells over time, causes destruction of cellular newlineelements, such as genetic substances and lipids, and contribute to cellular necrosis, newlineleading to chronic disease. Considering the above, demand for quality tea production is newlinea frontline issue to the health conscious people. newlineIn view of the above, the recent challenges to the scientific world is to develop superior newlinecultivars (high yielding, disease resistance) with better aroma quality and elevated newlinenutraceuticals traits. Presently available tea cultivars are mostly developed through newlineselection of elite genotype from wild or controlled cross-pollinated members, and their newlinevegetative propagation followed by released as commercial clones . Only a few newlinecultivars are derived following conventional breeding. In recent times conventional newlinemethods are integrated with non-conventional or molecular techniques in order to time newlinesaving and with less laborious and better effectiveness.
