Problems solved by technology

The advantage of the organic solvent extraction method is that it is easy to operate and does not require complicated equipment; the disadvantage is that the consumption of organic solvents is high, time-consuming, and heating during extraction will cause oxidative degradation of anthocyanins
The microwave method and the ultrasonic method cannot carry out large-scale industrial production due to the limit value of the equipment.
Supercritical extraction can be industrialized at present, but due to the particularity of this technology, the cost of anthocyanins produced by this technology is high, and this product cannot be promoted to ordinary consumers

Embodiment 1

[0018] Put 1000kg of Sorbus berries and 5000kg of extraction solvent alkaline water (pH=12) into the extraction tank, and drop into the extraction tank 10kg of tea polyphenols with a purity of 95%. The extraction temperature is 70°C, and the extraction time is 90min. Extract 2 times and collect the extract; adjust the collected extract with acidic aqueous solution (pH=1) to make the pH between 3 and 5, and then add ZTC1+1 flocculant to it, the addition amount is 2 %, stirred for 5min at a temperature of 40°C, then stood still for 120min, centrifuged in a centrifuge, and collected the centrifugate; purified the centrifugate with D101 macroporous adsorption resin, collected the ethanol analysis solution; added 95% ethanol, so that the ethanol volume fraction reaches more than 85%, centrifuge after standing for 30 minutes, and collect the centrifugate; the centrifugate is concentrated under reduced pressure in vacuum, the vacuum degree is -0.08~-0.07Mpa, the concentration temperat...

Embodiment 2

[0020] 1000kg of Sorbus berries and 5000kg of extraction solvent alkaline water (pH=11) are dropped into the extraction tank, and 8kg of tea polyphenols with a purity of 95% are dropped into the extraction tank, the extraction temperature is 75°C, and the extraction time is 120min. Extract 2 times and collect the extract; adjust the collected extract with acidic aqueous solution (pH=1) to make the pH between 3 and 5, and then add ZTC1+1 flocculant to it, the addition amount is 2 %, stirred for 5min at a temperature of 40°C, then stood still for 120min, centrifuged in a centrifuge, and collected the centrifugate; purified the centrifugate with D101 macroporous adsorption resin, collected the ethanol analysis solution; added 95% ethanol, so that the ethanol volume fraction reaches more than 85%, centrifuge after standing for 30 minutes, and collect the centrifugate; the centrifugate is concentrated under reduced pressure in vacuum, the vacuum degree is -0.08~-0.07Mpa, the concent...

Abstract

The present invention belongs to the field of natural organic chemistry, and relates to an extraction and separation method for anthocyanidin derived from sorbus pohuashanensis fruits. According to the method, tea polyphenol is adopted as an antioxidant, extraction is performed under an alkaline condition, impurity removing is performed with a flocculant under an acid condition, primary purification is performed by using a macroporous adsorption resin, and secondary purification is performed by using an alcohol precipitation method so as to obtain the high-purity anthocyanidin product. The industrial method of the present invention has the following advantages that: 1, the water is adopted as the extraction solvent under the alkaline condition so as to substantially reduce the production cost compared with the conventional extraction using ethanol; 2, the tea polyphenol is added as the antioxidant during the extraction process so as to effectively reduce the anthocyanidin loss; 3, the flocculant is used to precipitate the impurities in the extraction liquid so as to easily improve the purity of the anthocyanidin product; and 4, the product is re-purified by using the alcohol precipitation method so as to significantly improve the purity of the anthocyanidin product. The prepared anthocyanidin of the present invention can be widely used in the fields of health food, cosmetics, and the like.

Description

technical field [0001] The invention belongs to the field of natural organic chemistry and relates to an industrialized method for preparing anthocyanins from wild rowan fruit. Background technique [0002] Anthocyanin is a water-soluble pigment that can change color with the acidity and alkalinity of the cell fluid. The cell fluid is acidic and reddish, and the cytosol is alkaline and blue. Anthocyanin is one of the main pigments that make up the color of petals and fruits. Anthocyanins are secondary metabolites of plants, which play an important role in physiology. Anthocyanins are pure natural anti-aging nutritional supplements. Studies have proved that they are the most effective plant antioxidants found by humans today. Its antioxidant properties Fifty times higher than vitamin E and twenty times higher than vitamin C. Its bioavailability to the human body is 100%, and it can be detected in the blood 20 minutes after taking it. It has a significant effect on enhancing...
