Description
Technical field
The present invention relates to plant extracts technical fields, and in particular to the extraction of anthocyanidin sterling in a kind of gynura bicolor blade
Method.
Background technology
Daily the eaten food additives pigment of people is divided into natural pigment and synthetic dyestuff, is sent out in synthetic food color
Before bright, the mankind it is initially use be all natural pigment, later since synthetic food color is at low cost, use currently on the market
In food color pigment nearly all be artificial color.With going deep into for research, it has been found that most artificial color food additive
Add agent that there is side effect, some synthetic dyestuffs, which have, to be caused to let out even carcinogenic danger.Natural pigment such as anthocyanidin etc. has safety
Property high and tool nutrition and health care and other effects, but the defects of natural anthocyanidin acquisition generally needs to expend higher cost and poor stability,
And the extract that the technique that tradition extracts natural anthocyanidin obtains is typically liquid state, is unfavorable for storing and apply, therefore, opens
Hair yield is high, it is good to stablize and is modern food industry development suitable for the solid-state like natural anthocyanidin sterling that the long period preserves
There is an urgent need to.
Gynura bicolor（Cynura bicolor）Alias kwan-yin dish, red phoenix dish, red back of the body dish, red dish, Gynura bicolor etc., are composite family
The ground such as gynura segetum category perennial herb plant, native to China, Japanese and Southeast Asia, in Fujian, Taiwan, Guangdong, Hainan
Etc. ground be distributed.In recent years, gynura bicolor is as a kind of commercialization plantation eaten vegetables raw and have certain area.Artificial growth is purple
It is few to carry on the back dish pest and disease damage, management is simple and yield is high, but eats gynura bicolor raw due to influencing it with peculiar taste as common
Vegetables large area is planted.Gynura bicolor face of blade green, back side purple, therefore it contains outside chlorophyll also rich in anthocyanidin（Bag
Include cyanidin, pelargonidin, delphinidin and high mallow element etc.）, special anthocyanidin aqueous solution that gynura bicolor is rich in（Or it dries
The dry anthocyanidin powder obtained) stability is strong, safe without toxic side effect, there is prevention cardiovascular and cerebrovascular disease, protect liver, anticancer, anti-
The multiple efficacies such as oxidation and removing free radical and enhancing body immunity, meanwhile, gynura bicolor anthocyanidin is to bacterium and saccharomycete
With apparent inhibitory action, there is good fresh-keeping effect, therefore natural food colour-cyanine is developed from gynura bicolor
Plain sterling will have broad prospects.
The content of the invention
It is an object of the invention to obtain a kind of natural anthocyanidin sterling, using gynura bicolor blade as raw material, by finishing,
The measures such as dehydration, ultrasonic wave extraction, spray drying obtain anthocyanidin sterling in gynura bicolor blade, this anthocyanidin sterling can conduct
The additives such as luxury food beverage have the multiple efficacies such as nutrition and health care and color protection.
The acquisition methods of anthocyanidin sterling, are as follows in a kind of gynura bicolor blade：
（1）Choose the gynura bicolor rich in anthocyanidin（Front is dark green, the back side is dark purple）Seedling carries out domestication
Cultivating and growing, when such gynura bicolor length is to 22 ± 3cm, harvesting top young stem and leaf grows 18 ± 3cm；Take its tender leaf and top
3-5cm young stem and leafs are material, and 110 DEG C of tea baking machines are put into after cleaning drying（Model：
TYS-6CHG-6）Finish 25-30min, then adjusts curer temperature to continuing between 68-72 DEG C to bake 90-100 min,
Make gynura bicolor leaves water loss 60% or so；
（2）Solvent is done using pure water, solid-liquid ratio is 1:3 to 1:4（g/mL）, 80 DEG C of temperature, power
Pass through ultrasonic wave under 270W environment（Model：KQ-33DE ）Extract 40-50min；
（3）Gynura bicolor mixture is squeezed with filtered through gauze and firmly, gained high concentration anthocyanidin aqueous solution carries out
Spray dryer is dried（Model：YC-1800 ；120 DEG C of wind turbine temperature；Pressure：0.2Mpa ）, finally obtain purplish red dyeing defect
Blue or green element sterling powder；
（4）The aubergine anthocyanidin sterling powder of acquisition can be directly used for the formula such as food or beverage or with brown
It is sealed after the packing of color vial, is preserved under 0-4 DEG C of environment and be used further to match somebody with somebody as food or beverage etc. within 6-8 months
Side.
The beneficial effects of the present invention are：
（1）The present invention by finishing and making after its appropriate dehydration ultrasonic wave extraction again, is obtained using rich in anthocyanidin gynura bicolor tender leaf
The anthocyanidin aqueous solution of higher concentration is obtained, is dried finally by spray dryer, acquisition stability is good within a short period of time, is suitable for
The anthocyanidin sterling that long period preserves.
（2）The gynura bicolor tender leaf annual output that the present invention takes is up to 2500Kg/666.7m2, anthocyanidin sterling obtains in tender leaf
Rate is up to 7.5%-8.5%, therefore, per 666.7m2The anthocyanidin sterling raw material that field can obtain 200Kg or so in 1 year, this flower
The alternative part synthetic food color of blue or green element sterling, and develop the different functionalities food with health-care efficacy.Meanwhile this side
The natural anthocyanidin sterling that method obtains not only has very high nutritive value and health-care efficacy, and yield is high, color is gorgeous, stablizes
Property it is good, have good development prospect.
