example 1

[0031] Example one, get cranberry fresh fruit 1kg, be ground into the particle of 0.5~0.6cm diameter, add the deionized water of 1 times of fresh fruit weight, add cellulase and be 0.5% of fresh fruit weight, 45~50 ℃ of insulated and stirred 12 hours, Add 3 times the weight of fresh fruit water, adjust the pH value to 2.0 with edible hydrochloric acid, stir and extract for 1 hour, then filter, extract with water once again in the same way, and combine the water extract; add 7 times the weight of the residue to the residue to obtain a concentration of 70 % ethanol solution, solid-liquid separation after reflux extraction, the extract is decompressed to recover ethanol, and the alcohol extraction concentrate is obtained; the water extract and the alcohol extraction concentrate are combined and filtered, the filtrate is passed through the macroporous adsorption resin D101, and deionized water Wash until the color of the effluent is light, then gradiently elute with 10-80% ethanol ...

example 2

[0032] Example two, get cranberry fresh fruit 5kg, be ground into the particle of 0.5~0.6cm diameter, add the deionized water of 1 times of fresh fruit weight, add pectinase and be 1.0% of fresh fruit weight, adjust pH value to 5.0 with citric acid, Stir at 40-50°C for 6 hours, add water 5 times the weight of the fresh fruit, then adjust the pH value to 3.0 with citric acid, stir and extract for 2 hours, then filter, extract with water once again in the same way, and combine the water extract; Add 50% ethanol solution with a concentration of 6 times the weight of the residue, reflux extraction, solid-liquid separation, extract the extract to recover ethanol under reduced pressure, and obtain the concentrated solution of alcohol extraction, combine the water extract and the concentrated solution of alcohol extraction and filter, and pass the filtrate through Macroporous adsorption resin D201, washed with deionized water until the color of the effluent is light, and then gradient...

example 3

[0033]Example 3: Get 5 kg of cranberry fresh fruit, grind it into particles with a diameter of 0.5 to 0.6 cm, add 1 times the deionized water of the fresh fruit weight, add amylase to be 2.0% of the fresh fruit weight, adjust the pH value to 5.5,45 with edible phosphoric acid Stir at ~50°C for 2 hours, add water 8 times the weight of fresh fruit, then adjust the pH value to 1.0 with edible phosphoric acid, stir and extract for 2 hours, then filter, extract twice with water in the same method, and combine the water extract; add to the residue The concentration of 5 times the weight of the residue is 60% methanol, the solid-liquid separation after reflux extraction, the extract is decompressed to recover methanol, and the alcohol extraction concentrate is obtained, the above water extract and the alcohol extraction concentrate are combined and filtered, and the filtrate passes through the large pores Adsorption resin AB-8, washed with deionized water until the color of the efflue...

Abstract

The invention discloses an extraction method of anthocyanin and original anthocyanin components in cranberry fruits, which comprises the following steps: crushing the cranberry fruits, enzymolyzing the crushed fruits with biological enzyme, and lixiviating with water under the condition of the pH value being in the range of 1.0-5.5 to obtain water extracting solution and residues; carrying out alcohol extraction on the residues, concentrating the obtained extracting solution and recovering alcohol to obtain alcohol extraction concentrated solution; and merging the water extracting solution with the alcohol extraction concentrated solution, adsorbing with macroporous absorption resin, washing the macroporous absorption resin with water, analyzing with water-containing alcoholic solution, and concentrating and drying the obtained analytical liquid to obtain a mixture containing the anthocyanin and original anthocyanin components. The extraction method of the invention has the advantages of simple process, strong equipment generality, small investment, high yield, low cost and applicability to large-scale production; and the obtained mixture can be used as a raw material of foods, healthcare products and medicines or an additive.

Description

technical field [0001] The invention relates to a method for extracting anthocyanin and proanthocyanidin components in cranberry fruit, and the extract can be used as a raw material for food, skin care products and medicines or as an additive. technical background [0002] Cranberry (Vaccinium macrocarpaon Aiton) is a plant of the Rhododendronaceae Vaccinium genus, also known as cranberry, commonly known as cranberry in Taiwan; it is distributed in North America, Canada and the United States, and the growth environment is a wet and humid place, adapting to pH4~4.5 The acidic soil, the fruit is red, 1-1.5cm in diameter, blooms from June to August, and matures from August to October. As early as in the United States, massa plunger began to be cultivated. At present, the cultivation area in the United States is relatively large, and it has been introduced to Russia and other European regions in recent years. The world's cultivated area is 370 million acres. [0003] Cranberry...
