Problems solved by technology

At present, there are monomer products such as vitamin C and flavonoids extracted from seabuckthorn on the market, but there is no mixture containing vitamin P prepared from seabuckthorn
Moreover, the preparation method mostly adopts traditional methods such as steam distillation, vacuum distillation, solvent extraction, etc., which have high cost, low yield, easy oxidation of the product, and cannot be completely removed by the solvent used for extraction.

Embodiment 1

[0020] (1) Juice extraction: Seabuckthorn fruit was washed and centrifuged at a speed of 3500 rpm for 10 minutes to obtain seabuckthorn juice;

[0021] (2) Degassing: take 100 kg of seabuckthorn juice obtained above and degas it under the condition of vacuum degree of 5.13 Pa and temperature of 43° C. until there is no obvious bubble under the stirring state;

[0022] (3) Enzymolysis: add 95% sodium hydroxide solution to the degassed seabuckthorn juice to adjust the pH to 3, and add pectinase in the membrane separation type enzymolysis reactor at an amount of 2 g / liter for enzymolysis 6 Hour;

[0023] (4) Degreasing: the seabuckthorn juice after enzymolysis is passed into a disc type degreasing machine for degreasing, and its content is controlled at 0.2%;

[0024] (5) Homogenization: The degreased seabuckthorn juice is homogenized twice with a high-pressure homogenizer at a temperature of 26 ° C. The first time is to homogenize under a pressure of 14 MPa for 3 hours, and the...

Embodiment 2

[0032] (1) Juice extraction: Seabuckthorn fruit was washed and centrifuged at a speed of 4000 rpm for 5 minutes to obtain seabuckthorn juice;

[0033] (2) Degassing: take 100 kg of seabuckthorn juice obtained above and degas it under the condition of vacuum degree of 5.33 Pa and temperature of 41°C until there is no obvious bubble under stirring state;

[0034] (3) Enzymolysis: add 95% sodium hydroxide solution to the degassed seabuckthorn juice to adjust the pH to 4, and add pectinase in the membrane separation type enzymolysis reactor at an amount of 4 g / liter for enzymolysis 2 Hour;

[0035] (4) degreasing: the seabuckthorn juice after enzymolysis is passed into a disc type degreasing machine for degreasing, and its content is controlled at 0.5%;

[0036] (5) Homogenization: The degreased seabuckthorn juice is homogenized twice with a high-pressure homogenizer at a temperature of 40°C. The first time it is homogenized under a pressure of 16.4 MPa for 5 hours, and the secon...

Embodiment 3

[0044] (1) Juice extraction: Seabuckthorn fruit was washed and centrifuged at a speed of 4500 rpm for 8 minutes to obtain seabuckthorn juice;

[0045] (2) Degassing: take 100 kg of seabuckthorn juice obtained above and degas it under the condition of 5.2 Pa in vacuum and 42° C. until the stirring state has no obvious bubbles;

[0046] (3) Enzymolysis: add 95% sodium hydroxide solution to the degassed seabuckthorn juice to adjust the pH to 3.5, and add pectinase in an amount of 3 g / liter to the membrane separation type enzymolysis reactor for enzymolysis 4 Hour;

[0047] (4) Degreasing: the seabuckthorn juice after enzymolysis is passed into a disc type degreasing machine for degreasing, and its content is controlled at 0.35%;

[0048] (5) Homogenization: The degreased seabuckthorn juice is homogenized twice with a high-pressure homogenizer at a temperature of 35°C. The first time is to homogenize under a pressure of 15 MPa for 4 hours, and the second time is to homogenize at ...

Abstract

The invention relates to a method for preparing mixture containing vitamin P from sea buckthorn, and is for the prupose of providing a method for preparing a mixture containing 0.5-50% of vitamin P and 2-30% of vitamin C through extracting juice, degassing, enzyme-hydrolyzing, degreasing, homogenize, reducing acid, desugarizing, millipore filtering, freeze drying and pulverizing. The method is simple; solve the problem of brown stain of highly active substance in sea buckthorn due to high temperature oxidation by adopting biologic-physical method at low temperature, has no requirement of any solvent, no residue, low cost, and high biologically active substance yield. Vitamin P and vitamin C is in coexistence in the product, which promotes absorption.

Description

[0001] The invention relates to a method for preparing a mixture of natural active substances from plant fruits, in particular to a method for preparing a mixture containing natural vitamin P from sea buckthorn. Background technique [0002] Sea buckthorn fruit, also known as sand jujube, vinegar willow fruit, black thorn, sour thorn, Qicharigana (Mongolian name), Dapu (Tibetan name), Jihan (Uyghur name), is a plant of the family Hippophae (Hippophae). rhamnoides L.) ripe fruit. Seabuckthorn is a rich resource of vitamin P (polyphenols and flavonoids), which can enhance the durability of the human body, reduce the permeability of capillary walls, prevent the destruction of vitamin C in the body, and promote the absorption of vitamin C. At present, there are monomer products such as vitamin C and flavonoids extracted from sea buckthorn on the market, but there is no vitamin P-containing mixture prepared from sea buckthorn. Moreover, the preparation method mostly adopts traditi...
