Embodiment 1

[0028] A method for preparing beverage using peony root pigment, comprising the following steps:

[0029] Step 1. Preparation of peony root pigment

[0030] a. Dig out fresh red peony roots, wash them with water, remove impurities, and then dry them to a moisture content of not more than 10% to obtain dried peony roots, pulverize the dried peony roots, and pass through a 20-mesh sieve to obtain Peony root powder, set aside;

[0031] b. In the peony root powder obtained in step a, add the ethanol solution of 5 times its weight and soak, the mass concentration of the ethanol solution is 70%, filter after soaking 2d, collect the filtrate, for subsequent use; add its weight 5% to the filter residue obtained after the filtration. times the ethanol solution, the mass concentration of the ethanol solution is 70%, filter after soaking for 2d, collect the filtrate, then merge the filtrate twice, for subsequent use;

[0032] c. The combined filtrate obtained in step b is placed in ...

Embodiment 2

[0036] A method for preparing beverage using peony root pigment, comprising the following steps:

[0037] Step 1, prepare peony root pigment, the preparation method is the same as that of embodiment 1;

[0038] Step 2. Use peony root pigment to prepare beverage

[0039] Take the prepared peony root pigment, dissolve it in water according to the ratio of the material to liquid ratio of 1:10, adjust the pH value to 6 with citric acid after the dissolution is complete, pass through a 200-mesh sieve to obtain a pigment solution, which is for subsequent use; Add it to the prepared beverage raw material liquid, the weight ratio of the beverage raw material liquid and the pigment liquid is 80:1. After mixing and stirring evenly, adjust the pH value to 5.5 with citric acid, and then age for 48 hours, and pass 200 mesh after ageing. Screen, homogenize twice and then fill, that is, to complete the preparation of beverages.

Embodiment 3

[0041] A method for preparing beverage using peony root pigment, comprising the following steps:

[0042] Step 1, prepare peony root pigment, the preparation method is the same as that of embodiment 1;

[0043] Step 2. Use peony root pigment to prepare beverage

[0044] Take the prepared peony root pigment, dissolve it in water according to the ratio of material to liquid ratio of 1:10, adjust the pH value to 5 with citric acid after dissolving completely, pass through a 200-mesh sieve to obtain a pigment solution, which is for later use; Add it to the prepared beverage raw material liquid, the weight ratio of the beverage raw material liquid and the pigment liquid is 50:1. After mixing and stirring evenly, adjust the pH value to 5 with citric acid, and then age for 42 hours, and pass 200 mesh after ageing. Screen, homogenize twice and then fill, that is, to complete the preparation of beverages.

Abstract

The invention mainly relates to a method for preparing beverage by using a peony root pigment. The method comprises the following steps: step one. preparing the peony root pigment, to be specific, drying obtained peony roots, crushing the peony roots so as to obtain peony root powder, then soaking and extracting by using ethyl alcohol, filtering, concentrating filtrate and drying so as to obtain the peony root pigment; and step two. preparing the beverage by using the peony root pigment, to be specific, adding water to the peony root pigment so as to dissolve the peony root pigment, adjusting pH value, sieving by using a 200-mesh screen so as to obtain pigment liquid for later use, adding the obtained pigment liquid to prepared beverage raw material liquid, mixing, uniformly stirring, adjusting pH, then ageing for 36-48 hours, sieving, homogenizing two times, and canning, thus finishing the preparation of the beverage, wherein the weight ratio of the beverage raw material liquid to the pigment liquid is (30-80): 1. According to the method, the peony root pigment is added to the beverage, so that the obtained beverage is right in color and good in safety without side effects and is a non-industrial synthetic product. Due to adoption of a full-ecological technology in a preparation process, the method has the advantages of energy conservation, environmental protection, healthcare and the like.

Description

technical field [0001] The invention relates to the application field of pigments, in particular to a method for preparing beverages using peony root pigments. Background technique [0002] At present, most of the pigments used are synthetic pigments, which are tar dyes, which not only have no nutritional value, but are also harmful to the human body. Long-term use will endanger human health and easily cause cancer. Therefore, plant dyeing has been mentioned again. Moreover, natural pigments have attracted more and more attention in the field of scientific research, and have a tendency to replace artificial pigments. [0003] The whole body of peony is a treasure, and its root bark, leaves, flowers and fruits all have good application value. Moutan cortex, the roots are excavated in autumn, the fine roots are removed, the root bark is stripped, dried in the sun, and used raw or fried. "Compendium of Materia Medica": "Nourishing yin and reducing fire, detoxifying spot poiso...
