Abstract

The invention relates to a tea beverage for relieving physical fatigue and a preparation method thereof, the tea beverage comprises the following components: water, an oolong tea extract, rhizoma polygonati, lycium barbarum polysaccharide, an aloe extract and xylooligosaccharide, and the oolong tea extract is obtained by extracting an oolong tea extract by a polyvinyl alcohol + ethyl acetate/sodium chloride aqueous two-phase system. The oolong tea extract concentrate is subjected to secondary processing and purification treatment through an aqueous two-phase extraction technology, so that beneficial active ingredients are more enriched, meanwhile, the unique taste and fragrance of oolong tea are not lost, the experience of a drinker is good, the fatigue state of the drinker can be obviously improved, and insomnia cannot be caused.

Description

technical field [0001] The invention relates to the technical field of functional tea beverages, in particular to a tea beverage for relieving physical fatigue and a preparation method thereof. Background technique [0002] As one of the symbols of China, tea not only has its cultural function, but also plays a very important role in human health. Oolong tea is one of many tea products in China, and its anti-fatigue effect on people has attracted widespread attention. In recent years, people have continued to conduct in-depth research on the anti-fatigue effect of oolong tea, and found that oolong tea extract can excite the nervous system, improve the reaction ability, and also enhance the oxygen supply capacity and delay the fatigue of the body. In particular, the functional components of theanine and γ-aminobutyric acid in tea have obvious effects against fatigue. [0003] Theanine, the chemical name is N-ethyl-L-glutamine, is a unique non-protein free amino acid in tea....
