Pu-erh tea: Fermentative process as a potentialized of sensory aspects and bioactive profile – a review

Abstract

Pu-erh is a fermented Chinese tea with characteristics of mild, woody flavor and dark red color. The preparation of the tea starts from leaves of Camellia sinensis in natura that undergo a drying in the sun. Its classification is given in two categories: a raw tea similar to green tea and a matured tea that is fermented. Matured tea has a higher market value due to the processes involved in manufacturing, especially in terms of aging. Pu-erh has numerous benefits for human health, which are closely related to the bioactive profile of the main chemical components of tea, being polyphenols, theabrownins, flavonols, polysaccharides, amino acids and alkaloids. The increasing introduction of Pu-erh tea in the diet of consumers results in the need to explore information associated with consumption through analysis of the available literature, addressing current scientific evidence. Therefore, the present review sought to elucidate the fermentative process of Pu-erh tea production, its chemical composition, its sensory aspects and health benefits.

Possible Mechanisms of Dark Tea in Cancer Prevention and Management: A Comprehensive Review

“…For example, Fu brick tea has a higher content of catechin and flavonoid glycosides, while Pu’er tea has a higher content of catechin derivatives, flavonoids, and alkaloids [ 7 ]. Studies have confirmed that dark tea has a high potential for anti-cancer activity for human health [ 8 , 9 , 10 , 11 ], and it is recommended as a nutritional supplement for the prevention and management of cancer [ 12 , 13 , 14 ]. Therefore, this review summarized the possible anti-cancer mechanisms of dark tea in the past 10 years through articles on the Web of Science, PubMed, and Google Scholar.…”
