Instant solid beverage containing natural tea catechin, theanine and stachyose

Abstract

The invention provides an instant solid beverage which is rich in natural tea catechin, theanine and stachyose. The used catechin is a tea extract of which the total content of catechin is above 90 percent and from which caffeine is removed; the theanine is extracted from tea; the stachyose is physically extracted from Chinese artichoke; konjac gum powder with different viscosities is obtained bypartial hydrolysis under the control of an enzymatic method. The beverage is prepared from the following components in percentage by weight: 60 to 80 percent of tea catechin, 10 to 30 percent of tea theanine, 1 to 10 percent of stachyose and 0.5 to 5.0 percent of konjac gum powder. The mixture is prepared into powder, blocks, particles or microcapsules. The catechin has the effects of resisting oxidation and clearing free radicals in a human body; the theanine has the effects of strengthening the brain and improving sleeping; the stachyose has good effects of improving intestinal flora and promoting calcium absorption; the instant solid beverage has good solubility, is ready to drink, has no tea leaves and is convenient to take and drink; and the instant solid beverage does not affect sleeping after being taken by the aged, pregnant, children, and patients with heart disease and neurasthenia.

Description

technical field [0001] It belongs to the technical field of deep processing of agricultural products, and especially belongs to the instant solid drink of natural tea catechin, theanine and stachyose. Background technique [0002] Tea catechins are a general term for a class of substances. Numerous studies at home and abroad have shown that they are effective in eliminating free radicals in the human body, anti-oxidation, anti-radiation, lowering blood sugar and blood lipids, antibacterial, preventing cardiovascular and cerebrovascular diseases, and anti-cancer. It is the most active component of tea polyphenols (Green Tea Polyphenols, GTP). There are seven main catechins with high content and strong activity in tea: E-C, EGC, D-C, EGCG, ECG, GCG and CG. [0003] At present, tea polyphenols have been widely used in food (ingredients and additives), medicine, health care products, daily chemicals (toothpaste, shower gel, shampoo, etc.), textiles, and air conditioning purific...
