Description
Technical field：
The present invention relates to anthocyanidin extractive technique field, and in particular to a kind of highly effective extraction method of purple sweet potato anthocyanin.
Background technology：
Purple potato, also known as purple sweetpotato, common perennial dicotyledon, draft, its is climing elongated, and stem is crawled ground.Purple potato
Potato meat color be purple, to the health substance of human nutrition, and be identified as special articles for use in recent years due to rich in anthocyanidin etc.
Kind.20-180mg/100 grams of anthocyanidin content, there is edible and medical value higher, is a kind of pure natural health food.
At present, the extracting method of widely used purple sweet potato anthocyanin is the cleaned section of purple potato, adds aqueous citric acid solution
Extract, the directly concentrated drying of dusting of gained extract solution, or extract solution is adsorbed using macroporous absorbent resin, then washed with ethanol
It is de-, drying of being dusted after concentrated ethanol.Wherein, extract solution is directly concentrated into drying of dusting, although the loss amount of anthocyanidin is small, but
Content is low；And utilize macroporous absorbent resin to process extract solution, and if selected polymeric adsorbent is poor to the Selective adsorption of anthocyanidin, meeting
Reducing anthocyanidin yield, and adsorb the anthocyanidin on resin needs a large amount of ethanol elutions, that is, allow to recycle ethanol,
Also cost input is considerably increased.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of purple potato that recovery rate is high, easy to operate and energy consumption is small flower
The highly effective extraction method of blue or green element.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of highly effective extraction method of purple sweet potato anthocyanin, comprises the following steps：
(1) purple potato cleaning：Purple potato is placed in service sink, and adds cleaning fluid to submerge purple potato, stirred every 15-30min
It is dynamic once to pull purple potato out after 1-2h, and purple potato individual layer is divided on sieve plate, 2-3min is rinsed using clear water, drain moisture；
(2) purple potato defibrination：Once purged purple potato is thinly sliced, is ground in sending into fiberizer in the lump with 5 times of weight portion water
Slurry, repeatedly defibrination three times obtain final product purple potato slurries；
(3) anthocyanidin is extracted：To pectase is added in above-mentioned gained purple potato slurries, it is sufficiently mixed, and add citric acid to adjust
Section solution ph is to 3.5, then is warming up to 45-50 DEG C of insulation standing 1-2h, is subsequently adding poloxamer and anion pp acyl
Amine, stirring makes it that 3-5h is stood after being completely dissolved, and finally crosses 200 mesh sieves, and gained filtrate is extract solution；
(4) extract solution is separated：During above-mentioned gained extract solution is added by the macroporous absorbent resin splitter that is made of filling, treat
Bottom is flowed out without solution, then in macroporous absorbent resin 2-3 times of 75% ethanol solution of weight portion of addition that will be moistened, gained mixing
Solution removes macroporous absorbent resin, obtains final product separating liquid in insulated and stirred 0.5-1h at 50-55 DEG C, sieving；
(5) powder processed：By in above-mentioned gained separating liquid feeding spray dryer, dry gained particle and be made through micronizer
Micro mist, obtains final product purple sweet potato anthocyanin.
The weight consumption ratio of purple potato slurries, pectase, poloxamer and PAMA is in the step (3)
100-150:1-2:3-5:2-3。
The cleaning fluid is made up of the raw material of following parts by weight：10-15 parts of pregelatinated wheaten starch, pre-gelatinized wheat form sediment
Powder 5-10 parts, cycloheptaamylose 3-5 parts, hydroxyethyl cellulose 1-2 parts, buckwheat powder 1-2 parts, sodium alginate 0.5-1 parts, leaves of Hawthorn
Freeze-dried powder 0.1-0.3 parts, 0.05-0.1 parts of Mi leaf freeze-dried powders, water 100-150 parts, its preparation method is：By pregelatinized starch,
Cycloheptaamylose and hydroxyethyl cellulose are added to the water, and are warming up to reflux state insulation mixing with the programming rate of 5 DEG C/min
10-15min, after naturally cool to addition pre-gelatinized wheaten starch and sodium alginate after 45-50 DEG C, then is incubated at 45-50 DEG C
Mixing 10-15min, is subsequently adding buckwheat powder, leaves of Hawthorn freeze-dried powder and Mi leaf freeze-dried powders, and gained is mixed into molten after being sufficiently mixed
In liquid feeding ball mill, 200 mesh sieves are crossed after grinding 5-8h.
Above-mentioned cleaning fluid can not only effectively remove the impurity of purple potato surface adhesion, save cleaning water consumption, moreover it is possible to play one
Fixed bactericidal effect, and it is safe to use, easily rinsed by clear water and removed.
Using preceding by pretreatment, its preprocess method is the macroporous absorbent resin：First macroporous absorbent resin is submerged
Yu Shuizhong, reflux state insulation mixing 5-10min is warming up to the programming rate of 5 DEG C/min, adds Sodium Polyacrylate and small
Soda ash, continues the insulation mixing 5-10min that flows back, and rilanit special and sodium citrate are added after naturally cooling to 50-55 DEG C,
Reflux state insulation mixing 5- is warming up to the programming rate of 5 DEG C/min again after 50-55 DEG C of insulation mixing 10-15min
10min, then naturally cools to room temperature, and filtering, gained macroporous absorbent resin is washed once, that is, complete the pre- of macroporous absorbent resin
Treatment.
The weight consumption ratio of the macroporous absorbent resin, Sodium Polyacrylate, saleratus power, rilanit special and sodium citrate
It is 15-20:0.5-1:0.1-0.2:0.5-1:0.1-0.2.
After macroporous absorbent resin is through above-mentioned pretreatment, not only strengthen the patency of its internal gutter, also greatly improve its suction
Desorption activity under attached activity and ethanol effect.
The beneficial effects of the invention are as follows：The highly effective extraction method of purple sweet potato anthocyanin of the present invention has easy to operate, energy
The characteristics of consumption is small, input cost is low, greatly reduces purple potato cleaning water consumption, shortens scavenging period, it is ensured that purple potato is clear after cleaning
Cleanliness；And by the extraction and separation method, the recovery rate of blue and white element is significantly improved, shorten extraction time, and by macropore
Polymeric adsorbent Selective Separation anthocyanidin, reduces loss amount of the anthocyanidin in extraction process.
