Problems solved by technology

At present, the Rosa roxburghii oral liquid produced from Rosa roxburghii raw juice on the market is difficult for consumers to accept because of the sour taste.
At the same time, thorn pear products mainly adopt traditional heat sterilization technology, which greatly destroys the V in thorn pear. C , SOD and other natural active ingredients
The problems referred to above have seriously limited the commercial value of Rosa Roxburghii Oral Liquid

Embodiment 1

[0027] In this embodiment, the prickly pear oral liquid is prepared according to the following method:

[0028] (1) select fresh frozen prickly pear fruit raw materials without rotting and deterioration;

[0029] (2) The prickly pear fruit is subjected to brush spraying, cutting, blanching and bubbling cleaning;

[0030] (3) Cold beating the prickly pear fruit, the temperature is less than or equal to 10 °C;

[0031] (4) performing a low-temperature oxygen-isolating juicer for the prickly pear pulp, the temperature is less than or equal to 10 °C, and the dissolved oxygen amount is 1 mg / L, to obtain the prickly pear original juice;

[0032] (5) processing with a horizontal centrifuge, the conditions are: 3000rpm, 10min;

[0033] (6) the ceramic membrane of 10kDa aperture carries out ultrafiltration separation, and the water content in the gained concentrated solution is 70%;

[0034] (7) the concentrated solution separated by ultrafiltration is mixed with a deastringent, and...

Embodiment 2

[0040] Prepare the prickly pear oral liquid according to the method of embodiment 1, the difference is that step 7) is as follows:

[0041] Use column chromatography to remove astringency: the decolorizing agent is AB-8 macroporous resin; the chromatography column is: caliber 50mm, height 500mm, column volume 800mL; AB-8 resin packing height is 2 / 3 of the chromatography column, and the upper The sample flow rate was 10ml / min, and the effluent was collected and performed step 8).

Abstract

The invention provides low-astringent transparent roxburgh rose oral liquid and a preparation method thereof. The method comprises the following steps: preparing roxburgh rose into roxburgh rose normal juice; performing centrifugal treatment on the roxburgh rose normal juice, and collecting supernate; performing ultrafiltration concentration treatment on the supernate to obtain a concentrated solution; performing deastringency treatment on the concentrated solution to obtain a deastringency solution; carrying out degassing and filling treatment on the deastringency liquid; and performing ultrahigh pressure treatment on the filled roxburgh rose juice to obtain the roxburgh rose oral liquid. Wherein the deastringency treatment is carried out by adopting macroporous resin. The roxburgh rose oral liquid prepared by the method is light in astringent taste, rich in nutritional ingredients, high in content, high in activity, simple and convenient in preparation method, low in cost and suitable for large-scale production.

Description

technical field [0001] The present invention relates to the field of food. Specifically, the present invention relates to a low-astringency transparent prickly pear oral liquid and a preparation method thereof. Background technique [0002] Rosa roxburghiiTratt (Rosa roxburghiiTratt) is the fruit of the Rosaceae perennial deciduous shrub Reeling Flower. It is a unique fruit in Southwest my country. Phenols, polysaccharides, trace elements and other active ingredients. Prickly pear fresh fruit medium V C The content reaches 1380~1470mg / 100g, the SOD activity reaches 5667~5797U / g, and the polyphenol content reaches 1822~2281mg / 100g, which is known as the "Three Kings Fruit". Studies have shown that prickly pear has anti-oxidation, anti-aging, antibacterial, stomach and digestion, regulating immunity, anti-tumor, hypoglycemic, hypolipidemic, anti-atherosclerosis, detoxification, hangover and liver protection. [0003] The tannin content in the fresh fruit of prickly pear is ...
