Description
Technical field
The present invention relates to the technical fields of food processing extraction, and in particular to a method of anthocyanidin is extracted by blueberry.
Background technology
Blueberry, a kind of small berries, for fruit in blue, color and luster beauty, blue by 1 layer of white fruit powder package, pulp is fine and smooth, plants
Son is minimum.Blueberry averagely weighs 0.5-2.5g, maximum weight 5g, edible rate 100%, sweet and sour palatability, and it is pleasant that there is perfume to feel well
Fragrance, for eat raw good merchantable brand.Blueberry contains super polyphenoils anthocyanidin, is that the most potent free radical that finds so far is clear
Except agent, body immunity is improved, various inflammation in vivo is eliminated, reduces the aging speed of skin and organ.Blueberry contributes to
It is also to have benefited from anthocyanidin contained in blueberry to improve immunity, and anthocyanidin has powerful inoxidizability in addition to oneself itself,
The absorption that can also promote vitamin C and vitamin E, to improve the immunity of the human body.
Invention content
Technical problem to be solved by the present invention lies in overcoming existing technological deficiency to provide, a kind of method is reasonable, nutrition is rich
A kind of method that anthocyanidin is extracted by blueberry rich, easy to make, easy to use.
The technical problems to be solved by the invention are realized using technical solution below:
A method of anthocyanidin being extracted by blueberry, which is characterized in that include the following steps:
(1) fresh blueberry is put and carries out fully drying 10-12 hours in the sun, cured;
(2) blueberry after curing is put into 75% ethanol solution of 3-5 times of parts by weight and is impregnated, and carried out slow
Stirring, makes the polyphenol substance in blueberry peel be substantially dissolved in ethanol solution and can play bactericidal effect, and soaking time is that 0.5-1 is small
When, blueberry is filtered out after the completion of impregnating, retains the ethanol solution of immersion;
(3) blueberry peel handled step 2 well, meat, seed separation, blueberry seed is ground with low temperature low speed burrstone mill,
The blueberry seed slurries for collecting grinding, blueberry juice is broken by blueberry peel and meat mixing with wall-breaking machine;
(4) the blueberry seed slurries that step 3 is collected are mixed with blueberry juice, the ethanol solution of step 2 is added, stirs evenly
Afterwards, the microwave treatment 5-10min under microwave frequency 2250MHz, power 600W stands 10-20 minutes, continues microwave treatment 5-
10min stands 10-20 minutes, continues microwave treatment 5-10min, and coprocessing 3 times is again heated to reflux state, recycles ethyl alcohol,
Obtain extracting solution;
(5) extracting solution macroporous absorbent resin mixed bed is adsorbed into 5-8h, 35-45 DEG C of adsorption temp recycles distilled water
Macroporous absorbent resin is washed, then desorbs 3-5h, 40-50 DEG C of desorption temperature, by gained ethyl alcohol stripping liquid through subtracting with 70% ethyl alcohol
Pressure concentration waits for that cooled to room temperature after ethyl alcohol recycling, residue are sent into freeze drier, dry institute to recycle ethyl alcohol
It obtains solid and micro mist is made to get anthocyanidin through micronizer.
Using preceding by pre-processing, preprocess method is the macroporous absorbent resin:First macroporous absorbent resin is submerged
Yu Shuizhong is warming up to reflux state heat preservation mixing 5-10min with the heating rate of 5 DEG C/min, adds Sodium Polyacrylate and small

Height pollutes low advantage;
(2) present invention carries out sunlight with drying maturation process before blueberry processing to blueberry, on the one hand plays ultraviolet sterilization
Effect, on the one hand plays quickening maturation to blueberry, the polyphenol substances such as the anthocyanidin in blueberry can be dramatically increased, to indigo plant
It is impregnated with ethanol solution before certain kind of berries extraction, the anthocyanidin on blueberry crust can be made fully to dissolve, increase carrying for anthocyanidin
Taken amount, does not waste more environmentally friendly, and is extracted jointly using blueberry peel, blueberry meat, blueberry seed, will not only waste, increase flower yet
The extraction of green element;
(3) present invention is purified using ethyl alcohol, safer compared to propyl alcohol, methanol equal solvent, is also more convenient recycling, has
Conducive to environmental protection, while microwave treatment is used, ethyl alcohol can be made to be merged evenly with solution to be extracted, dramatically speed up Polyphenols cyanine
The leaching velocity of element improves the recovery rate of Polyphenols anthocyanidin;
(4) present invention isolates and purifies Polyphenols anthocyanidin using macroporous absorbent resin mixed bed, obtained by raising
The time required to greatly shortening purifying while Polyphenols anthocyanidin purity, the loss of the Polyphenols anthocyanidin in purification process is reduced
Amount, and macroporous absorbent resin is pre-processed, not only enhance the patency of its internal gutter, also greatly improves its adsorption activity
Desorption activity under being acted on ethyl alcohol.
