Description

The processing method of the turbid juice debitterize of a kind of concentrated lemon
Technical field:
The present invention relates to lemon extract deep process technology field, is the processing method of the turbid juice debitterize of a kind of concentrated lemon specifically.
Background technology: lemon can make to contain in juice a large amount of bitter substances in process is squeezed the juice in processing, cause the concentrated lemon juice processing to have certain bitter taste, domestic do not have the enterprise that processes concentrated lemon juice merely, the external concentrated conventional debitterize of the turbid juice of lemon generally uses movable bed resin debitterize, enzyme preparation suppresses bitterness value method, the movable bed resin debitterized technique debitterize time is long, flesh-content to turbid juice has a certain impact, in debitterize process, can attach some pulp, and the regeneration of resin bothers, the consumption of water is large, enzyme preparation suppresses just to have covered bitter taste, in practice bitter taste is not reduced.
Summary of the invention:
The object of the invention is to overcome that movable bed resin directly carries out all restrictions of debitterize to turbid juice and processing method that the turbid juice debitterize of a kind of concentrated lemon is provided, mainly solve a debitterize difficult problem for the turbid juice of existing concentrated lemon.
In order to achieve the above object, the present invention is achieved in that
A processing method for the turbid juice debitterize of concentrated lemon, comprises following operation:
(1), squeeze the juice: the technique of squeezing the juice routinely, makes lemon juice;
(2), bar kills: lemon juice is killed through routine bar;
(3), enzymolysis: the lemon juice after bar kills is cooled to 50～55 DEG C to enter enzymatic vessel, doses pectase and stirs, and pectase addition is 10000～12000ml/10 ton tank, and enzymolysis time 15～20 minutes, makes enzymolysis juice;
(4), ultrafiltration: enzymolysis juice is filtered by three grades of ultrafiltration systems, and high pressure is 4.0～5.5Mpa, and low pressure is 0.2～1.0Mpa, and a secondary internal circulating load is 70～75m 3/ hour, three grades of internal circulating loads are 100～105 m 3/ hour, total clear juice amount is 2.8～4.0 m 3/ hour, super filtered juice amount is 88～90% of total enzymolysis juice amount;
(5), resin debitterize: adopt resin column to carry out debitterize in the clear juice of ultra filtration, resin content is 2.7～3.2 m 3/ post, super filtered juice is taking flow velocity as 3.0～4.0 m 3/ hour by resin, resin operation 17～22 hours, makes the clear juice of debitterize lemon;
(6), mix: the insoluble matter that the clear juice of lemon after debitterize and ultrafiltration are held back and the enzymolysis juice 5～10% without ultrafiltration, in the stainless cylinder of steel that is provided with agitator, stir, make the turbid juice of lemon;
(7), concentrated: by turbid lemon juice, through evaporimeter, technique concentrates routinely, and being concentrated to pol is 42-48Brix;
(8), cold-aseptic filling: the turbid juice of lemon after concentrated stirs in finished pot, carries out sterile filling;
Preferably, the turbid juice limonin of prepared concentrated lemon content <5ppm.
The invention has the beneficial effects as follows: the processing method of the turbid juice debitterize of a kind of lemon of the present invention is the much progress that turbid juice is produced debitterize technology, suitably reduce fruit juice viscosity in enzymolysis operation by the addition of determining pectase, adopt the ultrafiltration system of three-stage filtration to ensure the amount of resin clear juice used, retain the insoluble matter in juice completely, the enzymolysis juice amount that control enters ultrafiltration accounts for the ratio of total juice amount, adopt debitterize resin to remove the limonin of super filtered juice, several persons effectively coordinate, and make in the concentrated turbid juice of lemon limonin content below 5ppm.This debitterize concentrates the turbid juice technique of lemon, has improved debitterize efficiency, has extended the service life of resin, has greatly reduced the time of process, has improved output, has reduced production cost.
Brief description of the drawings
Fig. 1 is Technology Roadmap of the present invention.
Its concrete test is as follows
1, not definite (viscosity of reduction fruit juice and reserve part pectin do not affect the separation of ultrafiltration) of pectase addition
Adopt German WEISS pectase to test, to determine the impact of Different adding amount on ultra-filtration flux.
Figure DEST_PATH_DEST_PATH_IMAGE001
  
Pectase addition accounts for the impact (testing with the turbid juice of flesh-content <2%) of enzymolysis juice ratio on super filtered juice:
Figure RE-DEST_PATH_IMAGE003
2, clear juice determining through resin flow:the relatively removal effect of limonin under different flow.
(1) debitterize resin column adopts 3 m 3/ post
(2) experimental technique
1# scheme flow is 4.0 m 3/ hour;
2# scheme flow is 3.5 m 3/ hour;
3# scheme is 3.0 m 3/ hour.
(3) experimental result
Figure 2014100856375100002DEST_PATH_IMAGE004
(4) conclusion
I is when pectase addition reaches 10000ml/10 ton hour, and the addition that continues raising pectase is little to the contribution of super filtered juice flux, therefore, adds pectase 10000ml at 10 tons of enzymatic vessels.
Ii adopts 2# scheme, and super filtered juice limonin removal efficiency just reaches 96.74%.
III is added 10000ml pectase, super filtered juice accounts for 90% of enzymolysis juice total amount, according to the cubage of 2# scheme limonin, limonin content 4.0ppm (11.8Brix) in the concentrated turbid juice of lemon, meet <5ppm (11.8Brix) standard, and in turbid juice, limonin removal efficiency reaches 87.0%.
