Embodiment 1

[0034] Embodiment one of the present invention provides a kind of water-soluble roxburghii powder production process, comprises the following steps:

[0035] a. the fresh fruit of Rosa roxburghii is crushed to a particle size of 20 mesh to obtain scraps;

[0036] b. Mix the crushed material with 10bv of water, and then extract the resulting mixture for 20 minutes under the conditions of an ultrasonic frequency of 25KHz and a temperature of 40°C;

[0037] c. Utilize centrifuge to separate the substance obtained in step b, then filter to obtain filtrate;

[0038] d. Concentrating the filtrate to a solid content of 30% using a reverse osmosis membrane to obtain a concentrate;

[0039] e. drying the concentrate by spray drying until its water content is 5%, so as to obtain Rosa roxburghii powder.

Embodiment 2

[0041] Embodiment two of the present invention provides a kind of water-soluble Rosa roxburghii powder production process, comprises the following steps:

[0042] a. crushing the dried Rosa roxburghii to a particle size of 40 mesh to obtain fragments;

[0043]b. Mix the crushed material with ethanol with a mass percentage concentration of 40% and 15bv of water, and then extract the obtained mixture for 40min at an ultrasonic frequency of 40KHz and a temperature of 60°C. The mass ratio of ethanol to the crushed material is 15:2;

[0044] c. using a horizontal screw centrifuge to separate the substance obtained in step b, and then using an inorganic membrane with a pore size of 0.22 μm to filter to obtain a filtrate;

[0045] d. concentrating the filtrate to a solid content of 50% to obtain a concentrate;

[0046] e. dry concentrate, until its moisture content is 3%, obtains Rosa roxburghii powder.

Embodiment 3

[0048] Embodiment three of the present invention provides a kind of water-soluble Rosa roxburghii powder production process, comprises the following steps:

[0049] Pre-treatment: select fresh Rosa roxburghii fruits with plump fruit, no insect eyes, and no mildew;

[0050] a. Pour the fresh fruit of Rosa roxburghii into metaphosphoric acid with a mass percentage concentration of 5%, and pulverize it at 4°C until the particle size is 30 mesh to obtain crushed material;

[0051] b. Mix the crushed material with ethanol with a mass percentage concentration of 20% and 13bv of water, and then extract the resulting mixture for 30 minutes at a mixed ultrasonic frequency of 20KHz and 40KHz at a temperature of 50°C. The mass of ethanol and crushed material The ratio is 15:1;

[0052] c. For the extracted substance, it is separated by a horizontal screw centrifuge with a rotation speed of 2500rpm, clarified by a disc centrifuge with a rotation speed of 6000rpm, and then filtered by a c...

Abstract

The invention provides a production process for water-soluble roxburgh rose fruit powder, which belongs to the field of food and health care. The production process for water-soluble roxburgh rose fruit powder comprises the following steps: a, crushing roxburgh rose fruit to a particle size of 20 to 40 meshes so as to obtain a crushed material; b, mixing the crushed material with 10 to 15 bv of water and carrying out ultrasonic extraction on the obtained mixture at 40 to 60 DEG C for 20 to 40 min, wherein the frequency of ultrasonic extraction is 25 KHz and/or 40 KHz; c, separating substances obtained in the step b by using a centrifuge and then carrying out filtering so as to obtain filtrate; d, concentrating the filtrate until the content of solids is more than 30% so as to obtain a concentrate; and e, drying the concentrate until water content is lower than 5% so as to obtain the roxburgh rose fruit powder. The production process for the roxburgh rose fruit powder can prepare the roxburgh rose fruit powder with well preserved nutrients, eliminates damage of the roxburgh rose fruit due to pressing and decay of the roxburgh rose fruit in the transport process of the roxburgh rose fruit and prevents consumers from injury due to contact with the roxburgh rose fruit during purchasing.

Description

technical field [0001] The invention relates to the fields of food and health care, in particular to a production process of water-soluble Rosa roxburghii powder. Background technique [0002] Rosa roxburghii is a deciduous shrub of the genus Rosa in the family Rosaceae. It is the fruit of the silk-reeling flower of the plant, also known as Cili, Muli, Wenguangguo, and Songchungui. It is a unique wild plant resource in the Yunnan-Guizhou Plateau. It is mainly produced in Guizhou, Sichuan, There are also introductions and cultivations in Jiangxi, Hubei and other provinces. Rosa roxburghii fruit contains a large amount of flavonoids, vitamin C and polysaccharides and other pharmacological components. [0003] Among them, vitamin C is a type of hexose lactone compound synthesized in plants and most animals, but humans lack the key enzymes for its synthesis, so they can only be obtained from food. The content of vitamin C in Rosa roxburghii fruit is more than 5 times that of k...
