Problems solved by technology

[0003] Aronia adenocarpus fruit is often used to process fruit juice drinks, fruit wine, jam, fruit milk, candy and other products. However, due to the large amount of tannin in the fruit of Aronia adenocarpa, raw fruit tastes sour and has a bad taste, so it is not easy to be eaten raw. Consumers accept, therefore, there is an urgent need to find a deep processing method that can utilize the active ingredients of Aronia berries, especially anthocyanins, while overcoming the bad mouthfeel of Aronia berries

preparation example Construction

[0019] In the embodiment of the present invention, a kind of preparation method of the fruit anthocyanin extract of Aronia adenocarpus is provided, comprising the following steps:

[0020] 1) Degreasing the fruit of Aronia nigra;

[0021] 2) then extracted by mixed acid aqueous solution;

[0022] 3) Purifying and extracting the extract from the resin to obtain the dry extract of the fruit of Sorbus nigra.

[0023] Preferably, in one embodiment of the present invention, the degreasing treatment of the Aronia fruit in step 1) is to dry the Aronia fruit naturally so that the water content is lower than 7% by weight, Then reflux degreasing with the petroleum ether (60 ℃ ~ 90 ℃) of liquid material ratio 5:1 (volume:mass ratio), low-temperature drying, make water content be lower than 4% weight, obtain the good Aronia nigra fruit.

[0024] More preferably, in another embodiment of the present invention, the number of reflux degreasing of petroleum ether is 2 times, 30 minutes eac...

Embodiment 1

[0035] Example 1 Preparation of Aronia fruit anthocyanin extract

[0036] 1. Pretreatment of Aronia fruit: Dry the Aronia fruit naturally to make the water content lower than 7%, and then use the oil with a liquid-to-material ratio of 5:1 (volume mL: mass g) Ether (60 ~ 90 ℃) reflux treatment twice, 30min each time, mainly to remove lipids, pigments, etc. Drying at 50°C, so that the water content is lower than 4%, to obtain the pretreated Aronia fruit;

[0037]2. Extraction: the pretreated fruit of Aronia adenocarpus and the mixed acid aqueous solution (the pH value of the mixed acid aqueous solution is 2 to 3, and the mixed acid is a mixture of acetic acid and malic acid in a mass ratio of 1:1) by The liquid-to-material ratio (volume mL:mass g) was mixed at 6:1, soaked in the dark at room temperature for 48 hours, filtered, and the filtrate was set aside, and the filter residue was added to distilled water (according to the above-mentioned Adjust the pH value of the mixed a...

Abstract

The invention provides a preparation method of an aronia melanocarpa fruit anthocyanin extract. The preparation method comprises the following steps: carrying out degreasing treatment on an aronia melanocarpa fruit; then extracting with a mixed acid aqueous solution; carrying out resin purification, extracting an immersion liquid, and thus obtaining dry extract of the aronia melanocarpa fruit. The preparation method provided by the invention has the advantages that a pretreatment method such as appropriate degreasing is creatively used before an extraction step, and the aronia melanocarpa fruit anthocyanin extract (dry extract or powder) retaining anthocyanin to the utmost extent is obtained, wherein anthocyanin content is higher than 55%.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a preparation method of anthocyanin extract from Aronia nigra fruit. Background technique [0002] Aronia nigra, also known as aronia, bulimia, is a deciduous shrub of the family Rosaceae that has edible, medicinal, garden and ecological values. Its fruit is sweet and sour with slightly astringent taste, spherical shape, purple-black skin and dark red flesh. Aronia adenocarpa fruit is rich in a large number of nutrients, such as dietary fiber, sugar, protein, polyphenolic compounds, polyphenolic compounds are the highest content in known plants, polyphenolic compounds such as phenolic acid, proanthocyanidins, Anthocyanins, flavonols, etc. are rich in content, and are closely related to the biological activity of Aronia nigra. Anthocyanins and flavonoids have special health effects, which can protect the body from free radical damage, and have multiple functions su...
