Abstract

The invention relates to the field of tea drinks, in particular to a Lycium ruthenicum Murr tea drink and a preparation method thereof. The tea drink is characterized by comprising the following materials in parts by weight: 5-15 parts of a Lycium ruthenicum Murr extract, 0-20 parts of other traditional Chinese medicine flavor agents, and 0-100 parts of auxiliary materials, wherein the Lycium ruthenicum Murr extract is obtained by performing supercritical CO2 extraction on a product of fermentation of Lycium ruthenicum Murr. The Lycium ruthenicum Murr extract obtained by supercritical CO2 extraction is characterized in that the content of Lycium ruthenicum Murr polysaccharide and betaine is high and is different from a Lycium ruthenicum Murr extract in the prior art. In addition, the Lycium ruthenicum Murr tea drink is convenient to drink, unique in flavor and popular with people, is suitable for all people, and can achieve effect of enhancing immunity in daily life.

Description

technical field [0001] The invention relates to the field of tea beverages, in particular to a black fruit wolfberry tea beverage and a preparation method thereof. Background technique [0002] Lycium ruthenicum Murr is the dry fruit of Lycium ruthenicum Murr (Lycium ruthenicum Murr), which is called Alcatel in Uighur. Black fruit Lycium barbarum is a unique wild plant resource in some parts of Northwest my country. Its berries are spherical, purple-black when ripe, non-toxic and sweet. Black fruit wolfberry is rich in black fruit wolfberry polysaccharide, anthocyanin, betaine, gallic acid, protocatechin, catechin, chlorogenic acid, caffeic acid, syringic acid and so on. The content of calcium, magnesium, copper, zinc, manganese, iron, lead, nickel, cadmium, cobalt, chromium, potassium, sodium and other elements in black wolfberry was determined by atomic absorption method, and the results showed that the sodium content in black wolfberry was equivalent to , but the conten...
