A kind of thixotropic beverage and preparation method thereof

Abstract

The invention provides a method for preparing a natural thixotropic beverage with a simple preparation process, which comprises the following steps: (1) taking silkworm cocoons, removing silkworm chrysalis, taking cocoon shells, and washing them; (2) adding the cleaned cocoon shells Water, the cocoon shell and water are added in a mass ratio of 1:15-1:30, and boiled at 80-150°C for 10-120min to obtain silkworm cocoon soup; (3) filter the silkworm cocoon soup while it is hot, and pass Concentrate or dilute, and prepare sericin with a mass volume concentration of 1-50mg / ml relative to water; (4) add sugar with a mass volume concentration of 1-100mg / ml relative to water in the solution to obtain thixotropy drinks. The thixotropic beverage of the present invention is based on ancient medicine and modern science, has simple manufacturing process, low cost, does not contain any thickener, and combines the fun and functionality of the beverage.

Description

technical field

[0001] The invention relates to a thixotropic drink and a preparation method thereof, in particular to a sericin drink and a preparation method thereof. Background technique

[0002] Silk is mainly composed of two proteins with different properties, silk fibroin and sericin. Sericin covers the periphery of silk fibroin and plays a protective and adhesive role on silk fibroin. Sericin is a natural protein, which is mainly composed of 18 kinds of amino acids (8 of which are essential amino acids for human body), and amino acids with strong polar side groups such as hydroxyl, carboxyl and amino groups account for about 70% of the total, so Sericin is a water-soluble globular protein.

[0003] The content of serine (Ser), aspartic acid (Asp) and glycine (Gly) in the amino acid composition of sericin is relatively high. Serine can reduce the concentration of cholesterol in the blood and prevent and treat high blood pressure; it is also effective for tuberculosis ...

Examples

Embodiment 1

[0034] (1) get the silkworm cocoon, remove the silkworm chrysalis, take the cocoon shell, and wash;

[0035] (2) Put cocoon shells and water in a cooking pot at a mass ratio of 1:20, cook at 80°C for 120 minutes to obtain silkworm cocoon soup;

[0036] (3) Filter the silkworm cocoon soup while it is hot, add deionized water to dilute, and prepare a sericin solution with a mass volume concentration of sericin relative to water of 1 mg / ml;

[0037] (4) add the edible salt that is the edible salt of glucose and catalytic amount relative to the mass volume concentration of water of 70mg / ml, mix;

[0038] (5) The solution is sterilized under high temperature and high pressure to obtain a thixotropic beverage.

Embodiment 2

[0040] (1) get the silkworm cocoon, remove the silkworm chrysalis, take the cocoon shell, and wash;

[0041] (2) Put cocoon shells and water in a cooking pot at a mass ratio of 1:30, cook at 90°C for 60 minutes to obtain silkworm cocoon soup;

[0042] (3) Filtrating the silkworm cocoon soup while it is hot, concentrating it by blowing air, and preparing a sericin solution with a mass volume concentration of sericin relative to water of 25 mg / ml;

[0043] (4) Add maltose, fructose and a little essence with a mass volume concentration of 50 mg / ml relative to water, and mix well;

[0044] (5) The solution is sterilized under high temperature and high pressure to obtain a thixotropic beverage.

Embodiment 3

[0046] (1) get the silkworm cocoon, remove the silkworm chrysalis, take the cocoon shell, and wash;

[0047] (2) Put the cleaned cocoon shell and water in an airtight container at a mass ratio of 1:15, place the airtight container in an autoclave, and cook at 150°C for 10 minutes to obtain silkworm cocoon soup;

[0048] (3) Filtrating the silkworm cocoon soup while it is hot, concentrating it by blasting, and preparing a sericin solution with a mass volume concentration of sericin relative to water of 50 mg / ml;

[0049] (4) Glucose with a mass volume concentration of 70 mg / ml relative to water and a little wolfberry extract are added to the solution, and mixed evenly to obtain a thixotropic beverage.
