Problems solved by technology

However, in these tea concentrates or tea extracts, due to the extraction and concentration process, the boiling tea extraction method is used, which changes the composition of the tea leaves during the preparation process, especially the aroma in the tea leaves is basically lost and cannot be fully retained. The aroma of tea leaves keeps the taste and efficacy of tea drinks

Abstract

The present invention discloses an instant tea capsule, which comprises a tea concentrate and a capsule shell according to a mass ratio of the tea concentrate to the capsule shell of 70:30, wherein the tea capsule shell comprises, by weight, 70-80% of glutinous rice starch, 5-10% of an organic acid, and 10-20% of sodium bicarbonate, and the tea concentrate is screened with a 80-100 mesh sieve. According to the present invention, the tea concentrate retains most of the water-soluble components of the tea raw leaf, wherein the sodium bicarbonate and the organic acid in the capsule shell can be quickly subjected to the effervescent reaction and the produced gas bubbles are attached to the tea concentrate powder after the instant tea capsule is put into the infusion container and the capsule shell contacts the water, such that the tea concentrate can be promoted to be rapidly dispersed and dissolved so as to form the clarified and uniform tea beverage, wherein the tea aroma is rich; and the instant tea capsule has characteristics of easy carrying and easy infusion, can achieve the infusion with room temperature water, has advantages of rapid disintegration and rapid dissolution, and can achieve the good taste tea beverage.

Description

technical field [0001] The invention relates to the technical field of tea extract concentrates, in particular to an instant tea capsule and a preparation method thereof. Background technique [0002] China is the hometown of tea. As the most common drink in life, tea has the effect of fitness and curing diseases, which is related to the ingredients in tea. Studies have shown that tea polyphenols (catechins), tea pigments, tea polysaccharides, theanine and other ingredients contained in tea have anti-oxidation (eliminate oxygen free radicals), anti-inflammatory, antibacterial, enhance immunity, reduce blood fat, Bi-directional regulation of blood pressure and blood lipids, anti-atherosclerosis, improvement of microcirculation and multiple effects of reducing the incidence of cardiovascular disease. [0003] Chinese people have a history of drinking tea for more than 4,700 years. In daily life, people obtain tea beverages by brewing tea leaves. In this case, the brewing pro...
