Problems solved by technology

[0004] The present invention attempts to add tea extract essence EGCG, milk protein essence whey powder and soybean protein essence soybean protein isolate under the premise of ensuring that the nutritional components are not affected, and these essences are combined to prepare an acidic protein drink, so that the Beverages contain a small amount of pure EGCG, which plays a health-care role for the human body. However, due to the poor stability of EGCG, it is easy to decompose and precipitate, and EGCG is easy to be oxidized and lose its efficacy. Therefore, the above problems must be overcome when preparing beverages that add EGCG. At the same time, ensure that the added complex protein has good stability

Embodiment 1

[0033] 1. Preparation of original protein drink

[0034] Formula: (calculated per 100 grams of product)

[0035] 0.24 grams of soybean protein isolate (including 0.22 grams of pure soybean protein isolate), 0.62 grams of whey protein concentrate (WPC-80) (including 0.5 grams of pure whey protein concentrate), 0.5 grams of oligosaccharides, 1 gram of polydextrose, fruit glucose Syrup (Type 55) 1 g, honey 0.5 g, compound stabilizer (pectin: sodium carboxymethyl cellulose = 1:3) 0.3 g, epigallocatechin gallate 5.0 mg, glycyrrhizin 0.01 g, Xylitol 0.01g, maltitol 0.01g, citric acid 0.3g, L-sodium ascorbate 0.01g, original flavor 0.08g, add water to 100g.

[0036] making process:

[0037] 1) Dissolution of the stabilizer: Mix the stabilizer into the hot water of ingredients at 75-80°C, shear and stir, disperse and dissolve, and cool to 40-50°C for later use.

[0038] 2) Dissolution of raw materials: Dissolve whey protein concentrate in batching water at 45-50°C, stir and hydrate...

Abstract

The invention relates to the field of beverage processing, in particular to EGCG (Epigallocatechin Gallate)-added compound protein acidic beverage and a preparation method thereof. According to the EGCG-added compound protein acidic beverage provided by the invention, the EGCG-added compound protein acidic beverage contains 0.7-1.0 part of protein, 0.3-0.6 part of stabilizer, 5*10<-3> to 20*10<-3> part of EGCG, 0.3-0.5 part of citric acid and 0.01-0.02 part of sodium L-ascorbate, based on 100 parts by weight of raw materials. According to the EGCG-added compound protein acidic beverage and the preparation method of the EGCG-added compound protein acidic beverage, the acidity is adjusted by adding the citric acid into the beverage, so that the pH value of the beverage can be in the range of 4.0 to 4.5, the EGCG can be stably present at the acidity, and soybean protein isolate and whey protein concentrate which are simultaneously added can also be stably present without flocculation; and bee honey, polydextrose and oligosaccharides are further added into the beverage, so that the EGCG-added compound protein acidic beverage has the advantages of comprehensive regulation and improvement on human metabolic function, excellent mouth feel and healthcare function.

Description

technical field [0001] The invention relates to the field of beverage processing, in particular to a composite protein acidic beverage added with EGCG and a preparation method thereof. Background technique [0002] Various protein beverages currently on the market mainly provide certain nutrients, water, vitamins, and minerals, but rarely combine plant protein essence, animal protein essence, and functional substances in beverages and other products. [0003] Epigallocatechin gallate (EGCG) is a component extracted from Chinese green tea. It is the main active and water-soluble component of green tea. It is the component with the highest content among catechins because of its special stereochemistry structure, EGCG has a very strong antioxidant activity, its antioxidant activity is at least 100 times that of vitamin C and 25 times that of vitamin E, it can protect cells and DNA from damage, and it plays an important role in anticancer and cardiovascular diseases. important ...
