Abstract
The invention discloses a kind of ascorbic extracting method of lemon, comprise the following steps：Step 1: peeling removes seed；Step 2: separation of solid and liquid, will remove the peel except the lemon after seed squeezes broken, and be put into centrifuge and carry out separation of solid and liquid, obtain lemon fluid；Step 3: microfiltration membrane impurity removal, micro-filtrate membrane filtration device is passed through by gained lemon fluid, the big molecular impurity in lemon fluid is removed, lemon juice clarification permeate is obtained；Step 4: separation UF membrane, is clarified permeate by lemon juice and is separated using separation film device, obtain seperation film permeate；Step 5: concentration film concentration, carries out concentration to seperation film permeate using device for ultrafiltration membrane, obtains vitamin C concentrate；Step 6: crystallization.The ascorbic extracting method of lemon of the present invention, is concentrated, isolation technics extracts vitamin C from lemon, simplifies production technology using film, improves production efficiency, and extraction process is carried out at normal temperatures, it is ensured that ascorbic quality.
Description
Technical field
The invention belongs to biological medicine preparation field, more particularly to a kind of ascorbic extracting method of lemon.
Background technology
Lemon is that most have one of fruit of medical value in the world, and it is rich in vitamin C, carbohydrate, calcium, phosphorus, iron, vitamin
B1, vitamin B2, nicotinic acid quininic acid, citric acid, malic acid, coumarin, a large amount potassium element and low amounts sodium element etc., to human body ten
Divide beneficial.Vitamin C can maintain the generation of the various tissues of human body and cytoplasm, and keep their normal physiological functions, people
Internal matrix, bonding and collagen etc., are required for vitamin C to protect when vitamin C to lack, the glue between cell
Thing also just and then tails off, and so, cell tissue will become fragile, and loses the ability of resistance external force, and human body is easy for scurvy occur.
Ascorbic extracting method is a lot, mainly there is molecular distillation technique method and membrane separation technique extraction method, UF membrane skill
Art is that material science is combined with intersecting for medium isolation technics, has the advantages that energy-efficient, equipment is simple, save, extensively should
Extraction for vitamin.
The content of the invention
Ascorbic lemon is simply extracted from lemon it is an object of the invention to provide a kind of energy-efficient, technique
Ascorbic extracting method.
A kind of ascorbic extracting method of lemon of technical solution of the present invention, comprises the following steps：
Step 1: carrying out peeling to citron fruit, except seed；
Step 2: separation of solid and liquid, will remove the peel, except the lemon after seed squeezes broken, is put into centrifuge and carries out separation of solid and liquid, obtain lemon
Liquid；
Step 3: microfiltration membrane impurity removal, removal of impurities film filter is passed through by gained lemon fluid, the macromolecular removed in lemon fluid is miscellaneous
Matter, obtains lemon juice clarification permeate；
Step 4: separation UF membrane, is clarified permeate by lemon juice and is separated using separation film device, obtain seperation film transmission
Liquid；
Step 5: concentration film concentration, carries out concentration to seperation film permeate using device for ultrafiltration membrane, obtains vitamin C dense
Contracting liquid；
Step 6: crystallization, gained vitamin C concentrate is cooled, solubility reduction, liberating vitamin C crystal.
It is preferred that, in the step 2, centrifuge speed is 200 r/min, centrifugation time 30 minutes.
It is preferred that, in the step 4, seperation film is milipore filter, and molecular cut off is 25000.
It is preferred that, in the step 5, ultrafiltration retaining molecular weight is 10000.
It is preferred that, the micro-filtration film device, separation film device, device for ultrafiltration membrane are equipped with high-pressure pump, flowmeter, temperature
Meter, regulating valve.
The technology of the present invention beneficial effect：
The ascorbic extracting method of a kind of lemon of the present invention, by the processing of lemon fluid separation of solid and liquid, at follow-up microfiltration membranes
Reason reduces live load, then many by being removed to lemon fluid progress micro-filtration film process removal big molecular impurity, separation film process
Sugar and macromolecular pectin obtain vitamin C concentrate, and finally concentrate is concentrated using milipore filter concentration systems, it is ensured that
Ascorbic quality, and improve crystallisation by cooling efficiency.
Brief description of the drawings
Fig. 1 is a kind of ascorbic extracting method flow sheet of lemon of the invention.
Embodiment
For ease of skilled artisan understands that technical solution of the present invention, in conjunction with Figure of description to the technology of the present invention side
Case is described further.
As shown in figure 1, a kind of ascorbic extracting method of lemon of the present invention, comprises the following steps：
Step 1: carrying out peeling to citron fruit, except seed；
Step 2: separation of solid and liquid, will remove the peel except the lemon after seed squeezes broken, and be put into centrifuge with 200 r/min, carry out solid-liquid point
From centrifugation time 30 minutes obtains lemon fluid；
Step 3: microfiltration membrane impurity removal, removal of impurities film filter is passed through by gained lemon fluid, operating pressure 5bar removes lemon fluid
In big molecular impurity, obtain lemon juice clarification permeate；
Step 4: separation UF membrane, is clarified permeate by lemon juice and is separated using separation film device, operating pressure 10bar,
Obtain seperation film permeate；
Step 5: concentration film concentration, using device for ultrafiltration membrane to seperation film permeate carry out concentration, operating pressure 20bar,
Obtain vitamin C concentrate；
Step 6: crystallization, gained vitamin C concentrate is cooled, solubility reduction, liberating vitamin C crystal.
Invention is exemplarily described above in conjunction with accompanying drawing for technical solution of the present invention, it is clear that the present invention is implemented
It is not subject to the restrictions described above, as long as the various unsubstantialities for employing inventive concept and technical scheme of the present invention progress change
Enter, or it is not improved the design of invention and technical scheme are directly applied into other occasions, in protection scope of the present invention
Within.
