Description
Technical field
The present invention relates to the extracting method of a kind of Caulis Sacchari sinensis polyphenol, particularly from cane stalk, sugarcane toppers, leaf of Caulis Sacchari sinensis, Caulis Sacchari sinensis
Extraction to polyphenols in slag.
Background technology
The polyphenol compound contained in Caulis Sacchari sinensis is cinnamic acid and the predecessor of flavonoid of self-assembling formation under the effect of enzyme
It is derived, cane stalk, sugarcane toppers, leaf of Caulis Sacchari sinensis, bagasse all contains abundant polyphenols, especially at growing point
Sugarcane toppers position around is more concentrated.Research shows, Caulis Sacchari sinensis polyphenol has important biological activity and multiple pharmacological function.Energy
Enough effectively remove free radical, anti-lipid peroxidation, antitumor, mutation, atherosclerosis etc..In food, medicine, change
The every field such as cosmetic all have wide practical use.China's Caulis Sacchari sinensis aboundresources, but it is used for supplying sugar industry, industry is raw
The a large amount of bagasse produced in product often become waste material and not only pollute environment, more waste useful resource, and therefore exploitation Caulis Sacchari sinensis is many
Phenol products, the comprehensive utilization improving Caulis Sacchari sinensis is necessary.
Polyphenols in plant tissue generally and protein, polysaccharide form stable chemical combination with hydrogen bond and hydrophobic bond
Thing, polyphenol is intermolecular is also such.Extract reagent and not only polyphenol is had good dissolubility, and there is fracture hydrogen bond
Ability.Selecting alcohol-water mix reagent to extract Caulis Sacchari sinensis polyphenol, ethanol can be beneficial to many with the hydrogen bond between saboteur and hydrophobic bond
The release of phenol.Extracting method about Caulis Sacchari sinensis polyphenol need to optimize further at present.
Summary of the invention
In order to overcome deficiency of the prior art, it is achieved the effective utilization to Caulis Sacchari sinensis polyphenol, the present invention uses microwave-assisted
Being fully dissolved out of extraction, beneficially polyphenols.
The extracting method of a kind of Caulis Sacchari sinensis polyphenol, comprises the steps:
Step one: pretreatment of raw material: original sugarcane material is soaked in 80 ± 2 DEG C of water-baths 2-5min enzyme denaturing, is cooled to 10
Below DEG C, dewatering, smashing, freezing standby;
Step 2: extract: with 50-65% (volume ratio) ethanol solution as extractant, according to feed liquid weight ratio 1:5-1:10
Ratio, use microwave radiation exaraction, Extracting temperature is 55-65 DEG C, and extraction time is 10-20min, and power is 540W;
Step 3: filter: carry out sucking filtration through suction filter pump after extraction, isolate residue, obtain filtrate;
Step 4: concentrate, reclaim: concentrated by rotated for filtrate in step 3 vaporizer, obtains Caulis Sacchari sinensis polyphenol concentrated solution
1, and reclaim ethanol;
Step 5: purification: Caulis Sacchari sinensis polyphenol concentrated solution 1 in step 4 is adsorbed through NKA-9 type macroporous resin, and uses
60%-80% (volume ratio) ethanol solution carries out eluting, obtains Caulis Sacchari sinensis polyphenol eluent;
Step 6: concentrate, reclaim: the rotated vaporizer of Caulis Sacchari sinensis polyphenol eluent in step 5 is concentrated, obtains Caulis Sacchari sinensis
Polyphenol concentrated solution 2, and reclaim ethanol;
Step 7: be dried: by Caulis Sacchari sinensis polyphenol concentrated solution 2 vacuum freeze-drying in step 6, obtain Caulis Sacchari sinensis polyphenol.
In described step 3, the pressure of sucking filtration is 20-30MPa.
In described step 4 and step 6, thickening temperature is 55-65 DEG C, and the time is 1-2h, and vacuum is 0.01-
0.015KPa。
In described step 7 vacuum freeze-drying be temperature be 60-70 DEG C, vacuum be 0.02-0.03KPa under the conditions of enter
Row, dry to moisture less than 4%.
In described step one, original sugarcane material is cane stalk, sugarcane toppers, leaf of Caulis Sacchari sinensis or bagasse.
When original sugarcane material is cane stalk in described step one, also include the step removed the peel by cane stalk.
The beneficial effects of the present invention is: utilize high temperature to soak enzyme denaturing in short-term, can effectively prevent enzyme effect in Caulis Sacchari sinensis
Enzymatic browning is caused to cause aldehydes matter to convert to quinones substance in aldehydes matter.Use microwave radiation exaraction, absorb microwave
After energy, cell interior pressure exceedes cell wall expansion ability to bear and causes cell rupture, accelerates intracellular organic matter diffusion, it is thus achieved that energy
The polar water molecules of amount transfers energy to other materials, accelerates warm-up movement, when thus improving extraction ratio and greatly reduce extraction
Between.Remove bulky grain insoluble matter, the rotated evaporation and concentration of filtrate through sucking filtration after extraction, obtain Caulis Sacchari sinensis polyphenol concentrated solution, sweet
Sugarcane polyphenol yield is up to 70%, and reclaims ethanol.The absorption of macroporous resin is the most clear to the impurity in Caulis Sacchari sinensis polyphenol concentrated solution
Removing, and carry out eluting with ethanol solution, rotated evaporation and concentration obtains the Caulis Sacchari sinensis polyphenol concentrated solution that purity is about 35%.Select
Caulis Sacchari sinensis polyphenol concentrated solution is dried by vacuum freeze-drying mode, and protection polyphenols is not destroyed to the full extent.Whole carry
Take process simply, easily operate, continuous large-scale production can be realized, without chemical agent residue, it is ensured that Product quality and safety.
