Embodiment 1

[0033] (1) Cleaning of raw materials: Wash the raw materials of the fresh berry and remove the rotten fruit;

[0034] (2) Juicing separation: weigh the cleaned fresh fruit and put it into the juice extractor, collect the juice and transport it to the juice storage tank for storage, and collect and transport the pomace to the extraction tank;

[0035] (3) Leaching: prepare citric acid solution, the mass concentration of citric acid solution is 0.05%; The pomace obtained by citric acid solution and step (2) is mixed in a mass ratio of 3:1, and stirred and extracted at 60° C. hour; Separation and filtration and collection of filtrate, the separation and filtration adopts nanoscale ceramic membrane filtration, the ceramic membrane pore size is 50nm;

[0036] (4) Adsorption on column: Adsorb the filtrate collected in step (3) on a macroporous resin column. The flow rate of the upper column is 100L / h. Elute until free of impurities; then elute with ethanol with a mass fraction of 8...

Embodiment 2

[0040] (1) Cleaning of raw materials: Wash the raw materials of the fresh berry and remove the rotten fruit;

[0041] (2) Juicing separation: weigh the cleaned fresh fruit and put it into the juice extractor, collect the juice and transport it to the juice storage tank for storage, and collect and transport the pomace to the extraction tank;

[0042] (3) Leaching: prepare citric acid solution, the mass concentration of citric acid solution is 0.09%; The pomace obtained by citric acid solution and step (2) is mixed in a mass ratio of 3:1, and stirred and extracted at 60° C. hours; separation and filtration and collection of filtrate, the separation and filtration adopts nano-scale ceramic membrane filtration, the ceramic membrane pore size is 30nm;

[0043] (4) Adsorption on column: Adsorb the filtrate collected in step (3) on a macroporous resin column. The flow rate of the upper column is 100L / h. Elute until free of impurities; then elute with ethanol with a mass fraction of 8...

Embodiment 3

[0047] (1) Cleaning of raw materials: Wash the raw materials of the fresh berry and remove the rotten fruit;

[0048] (2) Juicing separation: weigh the cleaned fresh fruit and put it into the juice extractor, collect the juice and transport it to the juice storage tank for storage, and collect and transport the pomace to the extraction tank;

[0049] (3) Leaching: prepare citric acid solution, the mass concentration of citric acid solution is 0.07%; The pomace obtained by citric acid solution and step (2) is mixed in a mass ratio of 3:1, stirring and extracting at 60°C for 4 -5 hours; separate and filter and collect the filtrate, said separate and filter adopts nano-scale ceramic membrane filtration, the ceramic membrane pore size is 30nm;

Abstract

The invention discloses a method for extracting anthocyanin from aronia melanocarpa. The method comprises the following steps of: (1) cleaning raw materials; (2) performing juicing and separating; (3)conducting extracting; (4) performing adsorbing on a column, and conducting eluting with ethanol; (5) carrying out vacuum concentration to a relative density of 1.12-1.15, adding citric acid into theobtained concentrated paste to adjust the PH value to 2.5-2.6, and then carrying out spray drying to obtain powder; and (6) adding a stabilizer into the powder prepared in the step (5) to prepare thearonia melanocarpa anthocyanin, wherein the stabilizer comprises ascorbic acid, vitamin E and a bamboo leaf antioxidant. The anthocyanin prepared by the method is stable in content, the problem thatthe content of anthocyanin is reduced in the storage process is avoided, and the anthocyanin can be stored for two years or more at normal temperature.

Description

technical field [0001] The invention relates to the technical field of anthocyanin extraction, in particular to a method for extracting anthocyanin from berry. Background technique [0002] Berry, also known as Aronia melanocarpa (Aronia melanocarpa), scientific name Aronia black fruit, is native to wet forests and swamps in eastern North America. Since 1989, my country has introduced 8 varieties from abroad. Abundant planting resources. Berry fruit is rich in polyphenols, sugars, organic acids, minerals, vitamins and various trace elements, among which the content of polyphenols is the highest among fruits. In recent years, domestic research on its function has increased. Its fruit juice has strong antioxidant properties, as well as anti-cancer, anti-inflammatory, prevent urinary tract infection, treat diabetes, protect the liver, and treat obesity. It has a remarkable effect on cerebrovascular diseases. Regular consumption of berry can adjust human body functions, regulat...
