specific Embodiment approach 1

[0016] Specific embodiment one: in the present embodiment, the extraction method of Vaccinium anthocyanin in the present invention is: select the mature fruit of Vaccinium vaccinia without mildew to be beaten, and add 60% to 90% ( volume) ethanol aqueous solution, the ratio of the lingonberry slurry to the ethanol aqueous solution is 1g: (10-30)mL, and then adopt quadruple countercurrent under the condition of ultrasonic temperature 25-40°C and ultrasonic power 90-120W The extraction column was subjected to countercurrent extraction for 20-40 minutes, and then vacuum filtration, concentration by rotary evaporation at 40° C., and vacuum freeze-drying at -50° C. for 24 hours were carried out to obtain the bilberry anthocyanin pigment.

[0017] Test this embodiment, the result is as follows Figure 1-5 shown.

[0018] Depend on figure 1 It can be seen that the yields of extracting bilberry anthocyanins from pure organic solvents and water are low, indicating that pure organic s...

specific Embodiment approach 2

[0024] Specific embodiment two: in the present embodiment, the extraction method of Vaccinium cranberry anthocyanin of the present invention is: select the mature fruit of Vaccinium cranium without mildew for beating, and add 80% (volume) ethanol to the Vaccinium cranberry slurry Aqueous solution, the ratio of the bilberry slurry to ethanol aqueous solution is 1g:30mL, and then under the condition of ultrasonic temperature of 35°C and ultrasonic power of 105W, the countercurrent extraction is carried out by four cascade countercurrent extraction columns for 30min under the condition of ultrasonic wave, and then successively through vacuum Filtration, concentration by rotary evaporation at 40°C, and vacuum freeze-drying at -50°C for 24 hours to prepare the bilberry anthocyanin pigment.

[0025] After the anthocyanin component of this embodiment is extracted 4 times, as Image 6 , it is regarded as the end of the 4th unit extraction, and the slagging and feeding operations are c...

specific Embodiment approach 3

[0026] Specific embodiment three: in the present embodiment, the extraction method of Vaccinium anthocyanins in the present invention is: select the mature fruit of Vaccinium unmodified for beating, and add 70% (volume) ethanol to the Vaccinium serovar Aqueous solution, the ratio of the lingonberry slurry to ethanol aqueous solution is 1g: 20mL, then conduct countercurrent extraction under the condition of ultrasonic temperature 35°C and ultrasonic power 100W for 20min under the condition of ultrasonic wave, then vacuum filter and concentrate by rotary evaporation at 40°C 1. Vacuum freeze-drying at -50°C for 24 hours to prepare bilberry anthocyanin pigments.

[0027] Ultrasonic-assisted countercurrent extraction of Vaccinium anthocyanins was extracted, and the effect of ultrasonic countercurrent on the extraction of Vaccinium anthocyanins is shown in Table 1.

Abstract

The invention discloses a method for extracting vaccinium uliginosum anthocyanin, belongs to the technical field of anthocyanin extraction, and aims at solving the technical problems that a vaccinium uliginosum anthocyanin extraction process in the prior art is overlarge in solvent consumption, low in extraction efficiency, over high in cost and not suitable for continuous operation. The method for extracting vaccinium uliginosum anthocyanin, disclosed by the invention, comprises the following steps: pulping vaccinium uliginosum fruits; adding an ethanol aqueous solution to vaccinium uliginosum slurry, and carrying out countercurrent extraction under ultrasonic assistance; and sequentially filtering, concentrating and carrying out freeze-drying, so as to prepare a vaccinium uliginosum anthocyanin pigment. The method disclosed by the invention is used for extracting the vaccinium uliginosum anthocyanin. According to the method disclosed by the invention, the extraction rate of the vaccinium uliginosum anthocyanin can reach 95%-100%; an extracting reagent is saved by 50%-80%; continuous operation can be achieved; the production time is saved; and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of anthocyanin extraction; in particular, it relates to a method for extracting anthocyanin from lingonberry. Background technique [0002] Dusi lingonberry (V.uliginosum L.), also known as Dusi, black bean tree (Daxing'anling), Dushi (Xiaoxing'anling, Yichun), etc., is one of the most important Vaccinium plants in my country, concentrated in the Greater and Lesser Khingan Mountains , Changbai Mountain. The output of Daxing'an Mountains can account for 90% of the country's total, and the annual output can reach hundreds of thousands of tons. The lingonberry fruit is rich in nutrients. In addition to conventional sugar, acid, vitamin C, and mineral elements, it also contains many substances that are beneficial to human health that conventional fruits do not have, such as: natural rhodopsin, anthocyanins, polyphenols , flavonoids and other ingredients have various physiological functions such as anti-oxidatio...
