Abstract
A kind of from the salt algae method of leaching carotene, it is to be leaching agent with the vegetables oil, algae weight is 1: 1～2 with the ratio of oil volume, 80 ± 2 ℃ of leaching temperatures.Keep once leaching in 1～2 hour thing through the oily molten product that separates, ultrafiltration must contain carotene 0.5～1%, one time leaching rate is 75～80%, algae-residue after the leaching is again through secondary leaching, separation, algae-residue is again through 40～80 ℃ of hot water slurrying, clarification separates, the dry algae albumen byproduct that gets, twice total leaching rate＞80%, the present invention is the complete non-waste technology that makes full use of raw material salt algae and leaching agent, is applicable to industrial applying.
Description
The invention belongs to the vegetables oil is leaching agent, extracts the processing method of natural Beta-carotene from unicellular salt algae.
Before the present invention realizes, from the salt algae, extract the method for natural Beta-carotene, be to utilize the dense algae thing (being commonly called as the saliferous algae sticks with paste) after gathering to add a kind of chemical substance, utilize vegetables oil directly to leach after the homogenate, though technology is fairly simple, but stick with paste the later solid-liquid separation difficulty of water content ambassador because of algae, adopt supercentrifuge.Equipment is expensive, and the higher algae of saliferous sticks with paste by force to equipment corrosion, and running cost is quite high.CN1044277 A makes leaching agent with vegetables oil or animal oil after adopting freezing heat to melt processing algae paste.The salt algae is weight ratio 1: 1 with the ratio of vegetables oil, makes the oil solution that contains carotene 1%.This method has overcome etching problem, but technological process is not described in detail, and filtered filtration residue does not deal with, and wastes bigger.
The present invention is for overcoming above-mentioned shortcoming, and providing a kind of is leaching agent extracts natural Beta-carotene from the salt algae complete process method with the vegetables oil.
The present invention realizes like this.With reference to accompanying drawing, 2. 1. freeze-dried algae powder once leach in 3. at a leaching can with vegetables oil, once leach thing 4. through a centrifugal separation process, an isolated leaching liquid through the ultrafiltration operation 5. ultrafiltration must contain the molten product of 0.5～1% natural beta-carotin oil 6.; Isolatedly once leach algae-residue and 7. 2. vegetables oil enter the secondary leaching can, 8. secondary leaching thing enters the secondary centrifuging separation circuit, secondary separation gained secondary leaching algae-residue enters pulping process again and 9. uses hot water slurrying, 10. the slurrying thing enters the clarification separation circuit again, and clarification separates the back solid part and advances centrifugal separation process for the third time
, drying process
Get algae egg white solid product
Vegetables oil leaching technology of the present invention be moisture 10～20% freeze-dried algae powder 1. be loaded on be equipped with vegetables oil 2. and the extractor that has a stirring mechanism 3. in.The ratio of volume (weight with) is compared in algae oil contact is 1: 1～2, stir heat up simultaneously jar in an air extract or use N out
2, CO
2Displace a jar interior air Deng non-oxidizing gas, in case in the algae or leach the carotene oxidation by air that and reduce extraction yield.Under 60～100 ℃ of (being preferably 80 ± 2 ℃) situations, kept 1～2 hour, this is for once leaching condition, this moment, carotene dissolved in oil phase, this once leaches thing and enters centrifugal separation process and 4. with tripod pendulum type batch centrifugal oily algae is separated, 5. extracting solution of gained uses super strainer ultrafiltration through the ultrafiltration operation, and ultrafiltration gained oil phase is and contains the molten product of 0.5～1.0% natural beta-carotin oil 6..Through centrifugation first time gained algae-residue enter the second extraction jar 7. with reinstate new plant oil from ultrafiltration operation gained filter and and carry out the secondary leaching.The leaching condition is with once identical, secondary leaching thing through the secondary centrifuging separation circuit of tripod pendulum type batch centrifugal 8., the separating obtained secondary leaching of secondary centrifuging algae-residue is with 40～80 ℃ of hot water
Slurrying 10 minutes again in the frame steel basin, 10. clarify after tripod pendulum type batch centrifugal carries out the algae water sepn at the clarification separation circuit, the algae-residue drying (airing, air-dry or with ebullated bed, air stream drying all can), dried algae-residue is the solid phase prod that contains algae albumen nearly 40%
, the packing back is as Foods or drinks additive, the separating obtained secondary raffinate of secondary centrifuging
With the separating obtained parting liquid of clarification
All returning a leaching can recycles.Return pulping process again after the water heating after the algae water sepn.
Vegetables oil of the present invention can be refined soybean oil, sesame oil, peanut oil, Semen Maydis oil, beggar's oil, willow wet goods.
The once extraction yield of leaching of the present invention can reach 75～80%, the total extraction yield in secondary leaching back＞80%
Vegetable oil extraction natural Beta-carotene technology of the present invention.Owing to adopt extracted twice, once slurrying and four separating technologies have again made full use of raw material freeze-dried algae powder and leaching agent, and intermediates recycle.And obtain oily molten product and solid algae albumen is paid product, and be a cover complete process, be applicable to industrial popularization.
Accompanying drawing is for the vegetables oil being leaching agent extraction carotene process flow diagram.
Embodiment:
Get freeze dried algae powder 250g, with purified soybean oil 500ml(weightmeasurement ratio be 1: 2) leaching can of packing into, extract a jar upper air out, under negative pressure, be heated to 80 ± 2 ℃, stir leaching after 1 hour, put into tripod pendulum type batch centrifugal, tell leaching liquid.The oily molten product that after ultrafiltration, must contain natural beta-carotin 0.8%.
With the new plant oil wash filter residue close with the filter residue oleaginousness, oil of telling that contains carotene and oily molten product merge.Filter residue is reentered into leaching can be added new plant oil and carries out second time leaching, the leaching condition is with for the first time identical, behind the separating, washing, the secondary leaching liquid is done replenishing of leaching agent for the first time, carry out the leaching first time with new algae, twice total leaching rate is that 82.4%(is in slag), the molten product A S of gained oil≤3ppm PB≤10ppm.
60 ℃ the hot water that filter residue after the secondary leaching adds twice filter residue weight slurrying 10 minutes again, the oil of telling after the clarification and secondary leaching liquid merge do the remaining water of leaching agent for the first time and algae-residue by centrifugation after, water returns slurrying usefulness again, and filter residue must contain the dried algae-residue 246g of moisture 5% after air-dry.
