Problems solved by technology

[0004] Invention patent CN03134577.8 adopts a single-bacteria fermentation process of adding RC212 active dry yeast at one time. At the same time, the acid adjustment method is to use D380 ion exchange resin to reduce acid after fermentation. As a result, the unique nutrients and nutrients in red raspberry fruit cannot be fully maintained. biological function
[0005] The above prior art does not solve the problem of fully utilizing the red raspberry seeds and increasing the natural nutritional components in the red raspberry juice

preparation example Construction

[0023] The invention provides a kind of preparation method of red raspberry seed extract, comprises the following steps:

[0024] 1) Crush the red raspberry seeds into powder, soak the crushed red raspberry seeds in 65-75% ethanol solution for 12-24 hours;

[0025] 2) After the treatment in step 1), reflux extraction is carried out, the extract is filtered, the filtered extract is evaporated by a rotary evaporator, and the solvent is recovered to obtain the red raspberry seed extract.

[0026] In a preferred embodiment, the mass of the pulverized red raspberry seeds in step 1) and the added volume of ethanol are 1:10.

[0027] In a preferred embodiment, the reflux temperature in step 2) is 75-85°C, and the reflux extraction time is 3h-5h.

[0028] In a preferred embodiment, it also includes purifying the red raspberry seed extract prepared in step 2).

[0029]In a preferred embodiment, the purification condition is that the solution obtained in step 2) is passed through the ...

Embodiment 1

[0045] Preparation method of red raspberry seed extract:

[0046] 1. Use a crusher to crush the red raspberry seeds into a powder state;

[0047] 2. In the extraction tank, soak the crushed red raspberry seeds with 70% ethanol solution for 12 hours (add the extractant at a ratio of 1:10 (g:ml)), and reflux and extract at 80°C for 3 hours. Filter the extract through a filter;

[0048] 3. Use a rotary evaporator to evaporate the filtered extract, and recover the solvent to obtain the crude extraction mixture of red raspberry seeds;

[0049] 4. Purification of red raspberry seed extract: Pass the mixed liquid of red raspberry seed crude extraction through the resin column at a flow rate of 2BV.h. Until it becomes turbid, the adsorbed red raspberry seed extract is finally eluted with 95% ethanol, and the eluate is collected. Rotary evaporation, solvent recovery, vacuum drying below 70°C for 2 hours, the dried product obtained is the red raspberry seed extract.

Embodiment 2

[0051] Preparation method of red raspberry seed extract:

[0052] 1. Use a crusher to crush the red raspberry seeds into a powder state;

[0053] 2. In the extraction tank, soak the crushed red raspberry seeds with 65% ethanol solution for 24 hours (add the extractant at a ratio of 1:10 (g:ml)), and then reflux and extract at 85°C for 3 hours. Filter the extract through a filter;

[0054] 3. Use a rotary evaporator to evaporate the filtered extract, and recover the solvent to obtain the crude extraction mixture of red raspberry seeds;

[0055] 4. Red raspberry seed extract: pass the mixed liquid of red raspberry seed crude extraction through the resin column at a flow rate of 2BV.h. When the macroporous resin is completely adsorbed, use distilled water to clean the impurities through the resin column until the cleaning water is not turbid. , and finally the adsorbed flavonoids were eluted with 95% ethanol, and the eluate was collected. Rotary evaporation, solvent recovery, ...

Abstract

The invention relates to preparing methods of a red raspberry seed extract product and red raspberry polymerization fruit juice, and belongs to the field of fruit juice type drinks. Red raspberry fruits and red raspberry seeds are adopted as main raw materials. The red raspberry polymerization fruit juice with a special flavor is obtained by juicing the red raspberry fruits to obtain red raspberry fruit juice; extracting the red raspberry seeds by an edible ethanol solvent to obtain the red raspberry seed extract product; purifying the red raspberry seed extract product with AB-8 macroporous adsorption resin; and adding the purified red raspberry seed extract product into the red raspberry fruit juice. The obtained polymerization fruit juice has a light red color, and drinking value and nutrition value of the red raspberry fruit juice are improved. The methods are simple in operation. The obtained products have high health care functions and a wide market prospect.

Description

technical field [0001] The invention relates to a preparation method of a plant extract and a plant fruit juice drink, in particular to a preparation method of a red raspberry seed extract and a red raspberry polymer juice. Background technique [0002] Raspberry is divided into red berry, black berry, and yellow berry. It is a berry economic fruit tree plant of the genus Rubus in the family Rosaceae. The cultivation of this plant originated in Europe and gradually formed an industry. It has a history of hundreds of years. At present, countries all over the world have gradually Cultivation of raspberry crops began, and by the end of the 1990s, the world's raspberry production had reached more than 35,640 tons. The raspberry fruit is an aggregate fruit that is red when ripe. Raspberry berries are rich in sugar, organic acid, vitamin C, vitamin E, vitamin P, vitamin B9 and hematopoietic compounds, and become a drug food that is beneficial to disease prevention and treatment, ...
