Abstract:
Scented tea is a kind of tea prepared from flowers or leaves after deep processing. It is rich in nutritional and functional components and has a positive effect on human health. Scented tea not only has the function of maintaining good health, but also has a certain effect on fitness; therefore, people like to use it as a drink in daily life, and during study and work. With the rapid development of the economy in recent years, the scented tea market has become increasingly prosperous. There are more than a hundred kinds of scented teas, including rose, jasmine, honeysuckle, chrysanthemum, osmanthus, and dandelion teas. In this study, the nutritional components, functional components, and bioactivity of jasmine, rose, chrysanthemum, and honeysuckle teas were reviewed. These four kinds of scented teas were found to contain proteins, vitamins, polysaccharides, catechins, theophylline, flavonoids, volatile oils, and other nutritional and functional components, which can effectively resist oxidation, delay aging, improve immunity, prevent and cure cardiovascular diseases, and kill and inhibit bacteria, among other bioactivities.
