Abstract

The invention discloses a selenium-rich lotus leaf compound tea beverage. The beverage is prepared from the following raw materials: lotus leaves, green tea, Vc and purified water, the mass ratio of the lotus leaves to the purified water is 1:(200-240), the mass ratio of the green tea to the purified water is 1:(200-240), and 0.01-0.015 g of the Vc needs to be added into every 100 ml of the purified water. The invention also provides a preparation method of the beverage. The preparation method comprises the following steps: step 1, mixing the green tea and the purified water, putting obtainedmixture into a water bath oscillator, and performing extraction treatment to obtain green tea juice; step 2, mixing the lotus leaves with the purified water, and performing extraction treatment in anultrasonic cleaning instrument to obtain lotus leaf juice; 3, mixing the green tea juice with the lotus leaf juice; step 4, filtering composite tea soup by using an Al2O3 ceramic membrane; step 5, adding the Vc into the composite tea soup; step 6, carrying out high-pressure homogenization treatment on a sample; step 7, carrying out ultrahigh-temperature instantaneous sterilization treatment on thesample; and step 8, canning the sample. The method is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of liquid beverage processing, and in particular relates to a selenium-enriched lotus leaf compound tea beverage, and also relates to a preparation method of a selenium-enriched lotus leaf compound tea beverage. Background technique [0002] Tea beverage refers to tea soup made from tea leaves through leaching, extraction, filtration and clarification processes, or on the basis of which, water, sugar solution, sour agent, food flavor and fruit juice or plant (grain) extract Composite beverages prepared by preparing and processing. Tea beverages are rich in effective ingredients such as tea polyphenols, lignin, flavonoids, alkaloids, etc., and have the effects of cooling and thirst quenching as well as nutrition and health care. As the world's largest producer of tea beverages, China is also the largest consumer. According to statistics, the consumption of tea beverages in my country reached 13.356 million t...
