The extraction device 210 comprises an extraction tank and a roxburgh rose fruit arranged in the extraction tank, wherein the extraction tank is provided with a sixth inlet end used for acid liquid to enter and a seventh outlet end used for extracting liquid to discharge, and the sixth inlet end is communicated with the third outlet end.
That is to say, the eighth exit end passes through the pipeline intercommunication with the sixth entrance point, and metasilicic acid concentrate after concentrating through first enrichment facility 150 can directly get into and draw the jar, carries out vitamin C's extraction to the rosa roxburghii tratt fruit that draws in the jar, can set up the circulation pipeline between the sixth entrance point of jar and the seventh exit end, can make metasilicic acid concentrate circulation flow back to and draw the jar in, carry out the flooding of rosa roxburghii tratt fruit to vitamin C in the rosa roxburghii tratt fruit is extracted, reduces remaining vitamin C in the rosa roxburghii tratt fruit.
In this embodiment, the concentration temperature of the first concentration device 150 is lower, is 40-50 ℃, and can be concentrated under the condition of positive pressure or negative pressure so as to obtain a metasilicic acid concentrated solution with lower temperature, and vitamin C is extracted after the metasilicic acid concentrated solution enters the extraction tank, so that the nutrients in the rosa roxburghii tratt fruit cannot be damaged, and the vitamin C nutrient components cannot be damaged.
In this embodiment, the metasilicic acid concentrated solution enters the extraction tank to extract vitamin C in the rosa roxburghii tratt fruit to obtain a vitamin C extract, the vitamin C extract is introduced into the second concentration device 220 to be concentrated to obtain a vitamin C concentrated solution, and the vitamin C concentrated solution is filtered by the second filtering device 230 and then enters the second product tank 240 to be stored.
Optionally, the concentration temperature in the second concentration device 220 is 40-50 ℃, and concentration can be performed under positive pressure or negative pressure, so as to obtain a metasilicic acid concentrated solution with a lower temperature, and after the metasilicic acid concentrated solution enters the extraction tank, vitamin C is extracted without destroying the nutrients in the rosa roxburghii tratt fruit and destroying the vitamin C nutrient components.
The metasilicic acid solution can extract vitamin C, vitamin A and dismutase from the roxburgh rose fruits, so that the vitamin C, the vitamin A and the dismutase enter the metasilicic acid solution, the obtained solution has various nutrients, and diversified elements can be supplemented for a human body.
Example 1
The preparation conditions of the metasilicic acid solution are shown in table 1,
TABLE 1 preparation conditions of the metasilicic acid solution
The obtained metasilicic acid solutions were prepared by the conditions in table 1, and the concentrations of the metasilicic acid solutions were measured as shown in table 2,
TABLE 2 concentration of metasilicic acid solution
As can be seen from table 2, in examples 1 to 4 and comparative example 1, the lower the hot water temperature is, the less effective the preparation of metasilicic acid is, the more complicated the preparation is, since the concentration treatment is required if a high-concentration solution of metasilicic acid is to be obtained, the energy consumption is required. It is understood from examples 3 and 5 to 7 that the concentration of the metasilicic acid solution is lowered as the number of cycles is smaller and the influence on the concentration of the metasilicic acid solution is not so great after 30 cycles or more in the case where the temperature of the hot water is the same.
Example 2
Vitamin C extraction was carried out using the metasilicic acid solution provided in example 3, the extraction conditions are shown in Table 3,
TABLE 3 extraction conditions of vitamin C solution
Vitamin C in the Rosa roxburghii Tratt fruit was extracted by the conditions in Table 3 to obtain vitamin C solution, the content of each component in the vitamin C solution was measured to obtain Table 4,
TABLE 4 vitamin C solution content
As can be seen from Table 4, when the fresh Rosa roxburghii fruit is used for extracting the vitamin C solution, the extraction effect is better when the concentration of the metasilicic acid solution is 30000-40000 ppm. When the dried roxburgh rose fruit is used for extracting the vitamin C solution, the extraction effect is better when the concentration of the metasilicic acid solution is 10000-20000 ppm. And the same amount of vitamin C is extracted, compared with the fresh roxburgh rose fruit, the concentration of the metasilicic acid solution required for extracting the vitamin C from the dried roxburgh rose fruit is lower.
The embodiments described above are some, but not all embodiments of the present application. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Claims (2)
1. A method for extracting a vitamin C solution is characterized by comprising the following steps: soaking dried fructus Rosae Normalis in metasilicic acid solution; the water content of the dried roxburgh rose fruit is 5% -10%, and the concentration of the metasilicic acid solution is 10000-20000 ppm.
2. The method for extracting vitamin C solution as claimed in claim 1, wherein soaking the dried fructus Rosae Normalis in the metasilicic acid solution comprises: and dipping and refluxing the metasilicic acid solution into an extraction device filled with the roxburgh rose fruits.
