Embodiment 1

[0033] A method for extracting red raspberry anthocyanins, comprising the following steps:

[0034] 2 kg of red raspberries are washed with clear water and added to the beater 1, and the red raspberries are fully crushed to form a raw material slurry. The red raspberry slurry and methanol solution are mixed at a mass volume ratio of 1: 12.5, and the temperature is 30 Under the condition of ℃ and 400W, ultrasonically extract in an ultrasonic extractor for 25min, extract the mixture A of red raspberry and methanol whose cell wall is fully broken; B, the supernatant B is the solution formed by mixing the organic solvent-soluble anthocyanins in the red raspberry and the organic solvent, and the precipitate is removed; the supernatant B is press-filtered to obtain the filtrate C;

[0035] The filtrate C was concentrated under reduced pressure at a temperature of 60°C to obtain the crude anthocyanin extract D; the crude anthocyanin extract D was passed through the XAD-7 macroporous ...

Embodiment 2

[0037] like Figure 1-4 As shown, the red raspberries are washed and added to the beater 1, the red raspberries are beaten into a slurry by the broken shaft rotating in the beater 1, and methanol is added to the beater 1, and the addition method can adopt the existing adding method. The mechanism communicates with the top of the beater 1, on the one hand as a solvent for cleaning the beater 1, and on the other hand as a solvent for red raspberries, and then opens the valve 2 between the beater 1 and the ultrasonic extractor. extractor, figure 1 Not shown in , the ultrasonic extractor should be connected between the beater 1 and the centrifuge 3. Under the conditions of 30°C and 400W, ultrasonically treat for 25 minutes to ensure that the cell wall is completely broken, and then open the gap between the ultrasonic extractor and the centrifuge 3. Valve 2, the solution enters the centrifuge 3 and is centrifuged for 20 minutes, and the centrifuged supernatant enters the concentra...

Embodiment 3

[0040] like Figure 1-4 As shown, when the supernatant is extracted from the solution centrifuged by the centrifuge 3, the drive rod 335 slidably connected to the top of the cavity drives the filter press plate 33 to move downward. 3311 is staggered with the sealing plate 333 connected by swivel 332 on the driving rod 335, and the supernatant is squeezed to the top of the filter plate 33 through the filter hole 3311. When the driving rod 335 moves down to contact with the sediment, due to the spring 334 The bottom end and the swivel 332 are connected in a non-perpendicular manner. At this time, part of the tension of the spring 334 on the swivel 332 is converted into a lateral force on the swivel 332 to make the swivel 332 rotate relative to the drive rod 335 until the swivel 332 The sealing plate 333 fixedly connected on the top is in conflict with the retaining rod 3312 on the pressure plate with holes 331, and the sealing plate 333 completely closes the filter hole 3311 to se...

Abstract

The invention discloses an extraction method of red raspberry anthocyanin, and relates to the field of anthocyanin extraction, the red raspberry after cleaning and impurity removal is used as a raw material, the anthocyanin is extracted through pulping, ultrasonic extraction, centrifugation, concentration, adsorption, elution, concentration and drying, the red raspberry cell wall is broken through a pulping machine and an ultrasonic extractor, the anthocyanin is exposed in an organic solvent, the other substances in the cells are separated from a solution dissolved with anthocyanin through centrifugation, a crude extracting solution is obtained after vacuum concentration, the crude extracting solution is filtered, adsorbed, eluted, collected, concentrated and dried to obtain anthocyanin, the integrated red raspberry anthocyanin extraction equipment is adopted, the extraction rate is increased, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of anthocyanin extraction, in particular to a method for extracting red raspberry anthocyanin. Background technique [0002] Anthocyanins have anti-oxidation and free radical scavenging functions and anti-mutation functions, and are widely used in food production as natural additives. Red raspberry anthocyanins are anthocyanins extracted from red raspberries. nutritional value. [0003] The application document with the patent number CN108003128B discloses a method for extracting grape seed proanthocyanidins. The invention overcomes the difficult problem of proanthocyanidins in the seed coat of grape seeds and the high degree of polymerization of proanthocyanidins in the extract, uses Aspergillus niger as the strain to ferment grape seeds, and utilizes cellulase, pectinase and other enzymes produced by Aspergillus niger to degrade The grape seed coat is beneficial to the dissolution of proanthocyanidins. Different v...
