Description
Technical field
The present invention relates to the supercritical carbon dioxide method for extracting of lycopene in a kind of dry powder of tomato peel.
Background technology
At present, do not retrieve as yet from the tomato skin powder and extract lycopene method.In the world, have only Xinjiang red sail Bioisystech Co., Ltd according to application for a patent for invention number to be: the technology of " 200410056828.5 preparation technologies that are called dry powder of tomato peel " is produced the tomato skin powder.In order from above-mentioned dry powder of tomato peel, to obtain lycopene, be necessary to provide a kind of at this tomato skin powder extraction lycopene method.
Summary of the invention
The extracting process that the purpose of this invention is to provide the lycopene in a kind of dry powder of tomato peel, this method is easy, efficient, productive rate is high, has very high using value.
Be the supercritical carbon dioxide method for extracting of lycopene in a kind of by the following technical solutions dry powder of tomato peel of the present invention that achieves the above object, it is characterized in that: it may further comprise the steps: put into dry powder of tomato peel in the extraction kettle, and feed supercritical CO
2The fluid-mixing of fluid and extraction aid, the extracting pressure of control extraction is 28-50Mpa, extraction temperature is 45-70 ℃, the extraction time is 1.5-5 hour, and carbon dioxide consumption: 20-60 is (carbon dioxide volume/weight of material) doubly, and extraction aid is a lower alcohol, extraction aid consumption: 5-30% (extraction aid volume/weight of material), after the extraction, decompression separation goes out extract, and carbon dioxide returns CO
2The source.
Employed dry powder of tomato peel among the present invention, its preparation technology's process description is as follows:
1, the skin seed separates
The separation of tomato skin seed mainly relies on the gravity suspension method to finish.Separation can be at ambient temperature, has in the pond of following structure to carry out.At first the skin slag is put into the pond, add water and stir evenly.Water consumption is controlled at 6-30 doubly (W/W skin seed mixture).Needed mechanical agitation then 30 minutes.Time of repose after stirring＞2 hours.The row's of opening hole skin is emitted severe edema due to hypofunction of the spleen mixture.Dewater with 20 order nylon net filters, obtain the fresh fruit skin.Skin: seed=1: 1 (W/W).At last, the seed aqueous mixtures is discharged in the row of opening seed hole, dewaters with 20 order nylon net filters, obtains bright seed.
2, pulverize
The fresh fruit skin is ground into latex needs three crushing process altogether.First and second employing colloid mills.The colloid mill roll flute is a diamond structure, when grinding for the first time, adds 0.5 times in water (W/W tare weight), and the roll flute spacing is pine (adjustment disk loosens 3.5 circles).When grinding for the second time, need not to add water, roll flute spacing tight (adjustment disk loosens 1.5 circles).After grinding for the second time, the latex distribution of particle sizes:
＞20 orders:＜5% (W/W)
20-40 order: 40% (W/W)
＜40 orders:＞45% (W/W)
Pulverize for the third time and adopt high-speed shearing machine.After shearing, the latex distribution of particle sizes:
＞20 orders: do not have
20-40 order:＜20% (W/W)
＜40 orders:＞80% (W/W)
3, spray-drying
(1) equipment
Adopting the design evaporation capacity of drying tower is 130 kilograms/hour, and tower body is by nozzle, cylinder (internal diameter=3.6 meter; Height=7-14 rice), cone (maximum inner diameter=3.6 meter; Height=2.2 meters), the powder outlet is formed at the bottom of form, vibration hammer, turn hammer, the outlet of whirlwind powder and the tower.Tower body inwall and nozzle are made by L316 type stainless steel.It is aerosol type that nozzle is installed in cat head center nozzle arrangements, and the fluid tangent line of nozzle outermost spray orifice ejection and the angle of horizontal direction are miter angle, bore 16-22 millimeter.All the other structures are with general drying tower.
(2) method
Be transported to cat head nozzle place through the latex of shearing by delivery pump, through the nozzle atomisation.The dry powder that forms can be respectively from the cat head nozzle, through the nozzle atomisation.The dry powder that forms can be respectively at the bottom of the tower mouth and whirlwind mouth collect.The cat head intake air temperature is 170-200 ℃, and powder air outlet temperature is 80-90 ℃ at the bottom of the tower.
Tomato skin dry powder
The water content of whirlwind mouth powder is 17-20%
The water content of powder is 20-25% at the bottom of the tower
The pigment content of powder is about 0.15-0.2% at the bottom of the tower
The pigment content of whirlwind mouth powder is about 0.13-0.15%
Total dry powder (powder at the bottom of the tower+whirlwind mouth powder) flour extraction: 8.6% (W/W fresh weight).
