Abstract
The invention discloses a kind of preparation method of Pitaya Flower polysaccharide, belong to the processing method of Pitaya Flower.Its method is：Pitaya Flower baking is dry, ultramicro grinding, mixed after freezing with cold water, infusion 3 hours；Then cool down, filter, centrifuge, collect supernatant；Alcohol analysis, precipitation, RO membrane filtrations, mixed after filtrate concentration with dextrin；Spray drying, obtains powdered Pitaya Flower polysaccharide.The inventive method is simply efficient, and gained polysaccharide bioactivity is good, the rate of polysaccharide is high；It is a kind of method that polysaccharide is extracted from Pitaya Flower.
Description
Technical field
The present invention relates to a kind of method that polysaccharide is extracted from fruit, more particularly to one kind to prepare polysaccharide using Pitaya Flower
Method.
Background technology
Polysaccharide is a kind of calm macromolecule polymer, is widely present in nature.Polysaccharide and its compound mainly come to
Calm macromolecular substances in plant, animal cell membrane and microorganism rill wall.Polysaccharide can improve fibrinoclase
Activity, reducing blood lipid, drop neutral fat, drop T-CHOL and LDL-C, there is an obvious antitumaous effect, and plant is more
Sugar is also hypoglycemic, removes the function such as free radical, anti-aging, anti-oxidant, antifatigue.
Pitaya Flower also known as Hylocereus undatus, common nightblooming cereus, hylocereus flower.It is rich in 17 kinds of amino acid, 6 kinds of vitamins, 8 kinds of micro members
Element, and the preciousness such as abundant water-soluble dietary fiber, phytalbumin, anthocyanidin, flavonoids, soap are sweet, glucose, alkaloid
Nutritional ingredient and medicinal ingredient；Nutrition library, medical storehouse, health care storehouse are described as, is a kind of rare natural food.Flue
Fruit flower with antibacterial, anti-inflammatory, relieve inflammation or internal heat, moistening lung, cough-relieving, strengthen immunity, hypoglycemic, reducing blood lipid, hypotensive, anticancer, treatment it is high
Uric acid disease, Constipation and other effects, while also beauty, beauty treatment, the effect of anti-aging.
In dragon fruit planting process, artificial flower thinning need to be carried out within 7~8 days after every batch of flower is buddingged.Climing of every result stays 1~
The normal full bud of 2 growths remains result, and remaining is directly abandoned as discarded object, causes the wasting of resources；If it can incite somebody to action
Polysaccharide in Pitaya Flower is extracted the economic benefit that undoubtedly can significantly improve dragon fruit plantation.
The content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide a kind of preparation side of Pitaya Flower polysaccharide
Method, this method have that simple to operate, recovery rate is high, low cost and other advantages.
To achieve these goals, the technical solution adopted in the present invention is as follows：
1）Pitaya Flower is cleaned, draining, baking are dry；
2）Dry Pitaya Flower ultramicro grinding will be toasted to 400~1200 mesh, freezed 30 minutes under conditions of -20~-10 DEG C；
3）By 1:28 weight is smaller than by the water mixing of the Pitaya Flower powder Jing Guo freezing processing and 4~8 DEG C, heating infusion 3
When, cooling, filtering；
4）Filtrate is centrifuged, collects supernatant；
5）The analysis of supernatant alcohol, precipitation；
6）RO membrane filtration precipitated liquids, by 15~18 times of concentration filtrates；
7）By 1:1 weight ratio will concentrate filtrate and be mixed with dextrin, spray drying, obtain powdered Pitaya Flower polysaccharide.
Compared with the prior art, the present invention with the above mentioned technical proposal there is an advantage in that：
1）As a result of ultramicro grinding technique, therefore Pitaya Flower cell wall rupture can be made, be advantageous to polysaccharide release therein
Out, so as to improving the recovery rate of polysaccharide；
2）As a result of freezing processing technique, Pitaya Flower cell is easier to rupture in the state of cold heat build-up is gathered, and can enter one
Step promotes the raising of polysaccharide yield；
3）It due to employing dextrin in concentration process, therefore how glycoxidative not only can effectively prevent, and powder can also be crystallized into,
Preserved beneficial to product.
It is demonstrated experimentally that preparing polysaccharide using the inventive method, average recoveries are up to 60.19 ㎎/g.
Embodiment
With reference to specific embodiment, the invention will be further described：
Embodiment 1
1）Pitaya Flower is cleaned, draining, baking are done to moisture content 8%；
2）Dry Pitaya Flower ultramicro grinding will be toasted to 400 mesh, freezed 30 minutes under conditions of -10 DEG C；
3）By 1:28 weight is than the water of the Pitaya Flower powder Jing Guo freezing processing and 8 DEG C is mixed, heating infusion 3 hours,
Cooling, filtering；
4）Filtrate is centrifuged, collects supernatant；
5）The analysis of supernatant alcohol, precipitation；
6）RO membrane filtration precipitated liquids, by 15 times of concentration filtrates；
7）By 1:1 weight ratio will concentrate filtrate and be mixed with dextrin, spray drying, obtain powdered Pitaya Flower polysaccharide.
Embodiment 2
Each step is the same as embodiment 1；Wherein, step 2）In Pitaya Flower be crushed to 1200 mesh, cryogenic temperature be -20 DEG C, step
3）In water temperature be 4 DEG C, step 6）18 times of cycles of concentration.
Embodiment 3
Each step is the same as embodiment 1；Wherein, step 2）In Pitaya Flower be crushed to 800 mesh, cryogenic temperature be -15 DEG C, step 3）
In water temperature be 6 DEG C, step 6）16.5 times of cycles of concentration.
