Abstract

The invention discloses a method for completely peeling off the orange segments by using pectase. The method can entirely peel off the fruit cores and wrap angles that usually can not be entirely peeled off by enzyme method and reduces subsequent manual cleaning-up procedures. Peeled orange segments are arrayed on the shelves according to the direction that the fruit cores are downward, and then the fruit cores are carried out enzymolysis for 2-6 hours by using the 0.5%-2% of pectase with pH 3.0-5.0 at the temperature of 20-50 DEG C; or the fruit cores are injected with 0.5-2mL and 0.5%-2% of pectase with pH 3.0-5.0 from the center at the top of the orange fruits and then peeling is performed after the enzymolysis for 2-12 hours at the temperature of 10-50 DEG C. After the pretreatment, the orange segments are put into the enzyme solution entirely for degradation so as to get the orange segments with complete peeling. The method is simple and practical and solves the disadvantage of being difficult to peel off orange segments completely by the enzyme method.

Description

The method of two sections full excystation clothing of enzyme process citrus fruit lobe

Affiliated technical field:

The present invention is the method that a kind of enzymolysis removes citrus fruit lobe capsule clothing, belongs to fruit processing and utilization field.

Background technology:

Oranges and tangerines are the first fruits of world's plantation output, and China's oranges and tangerines plantation area and oranges and tangerines can output occupy the first in the world.Oranges and tangerines excystation clothing technology is the critical process of producing oranges and tangerines can and oranges and tangerines cyst, and the excystation clothing all is to adopt the runner type soda acid to handle at present, and seriously polluted, the ton water consumption is big.Adopt biological enzyme to remove the capsule clothing and can alleviate these problems, enzyme is a kind of macro-molecular protein, and the diffusion coefficient in the capsule clothing is much smaller than little molecule soda acid, and therefore the speed of degraded will be lower than common acid-base method; Tangerine lobe capsule clothing is not the film of homogeneous, and is thinner at the back of tangerine sheet, and core and corner are thicker, directly adopt enzymolysis excystation clothing, the vascular bundle and the capsule clothing of fruit core and cornerite part can't be sloughed fully, influence product quality, and technology in this respect is still waiting further to improve and improve.

The invention provides the method that a kind of two step enzymatic isolation methods take off oranges and tangerines tangerine lobe capsule clothing entirely, this method is that method is simple and practical to the improvement of a step enzymolysis tangerine lobe excystation clothing.

Summary of the invention:

The object of the present invention is to provide a kind of method simply and easily, improve the removal efficiency that enzyme process is used for oranges and tangerines excystation clothing process capsule clothing.

Solution of the present invention is: will remove the peel the tangerine lobe and arrange on the top of the shelf downwards by the fruit core, fruit core position pH 3.0～5.0, behind 20～50 ℃ of enzymolysis 2～6h of 0.5%～2% pectase, the tangerine lobe is put into the degraded of pectase enzyme liquid fully obtain full excystation clothing oranges and tangerines tangerine lobe; Or from citrusfruit fruit top center to fruit in-core injection pH 3.0～5.0, the pectase enzyme liquid of 0.5～2mL 0.1%～2%, peeling behind 10～50 ℃ of enzymolysis 2～12h is put into the degraded of enzyme liquid more fully and is obtained full excystation clothing oranges and tangerines tangerine lobe.

Advantage of the present invention:

1. this method can solve the fruit core segment that is difficult to remove in the single step enzyme process oranges and tangerines excystation clothing and the capsule clothing of corner part, realizes the full excystation clothing of tangerine lobe.

2. this method is less to the damage of tangerine lobe, can reduce the percentage of damage of full excystation clothing tangerine lobe.

3. this method only needs to add a spot of equipment, handles simple, easy to utilize.

The specific embodiment:

Substantive distinguishing features that the present invention gives prominence to and remarkable result can further specify from following instantiation, but never are that the present invention is imposed any restrictions.

Embodiment 1:

Peeling satsuma orange tangerine lobe is arranged in downwards on the horizontal shelf by the fruit core, see accompanying drawing, with pH 3.0, the 1% pectase aqueous solution is dipped into tangerine lobe fruit core segment, behind 50 ℃ of enzymolysis 3h, take out the tangerine lobe and put in pH 3.0, the 1% pectase aqueous solution, 45 ℃ are continued enzymolysis 40min, and taking-up tangerine lobe water cleans up and promptly obtains full excystation clothing tangerine lobe.

Embodiment 2:

Inject pH 3.0 from satsuma orange fruit fruit top center to the fruit in-core, 1% pectase aqueous solution 2mL, behind 10 ℃ of enzymolysis 12h, the peeling distinguish, obtain pretreated tangerine lobe, the tangerine lobe is put in pH 3.0, the 1% pectase aqueous solution, 45 ℃ are continued enzymolysis 40min, and taking-up tangerine lobe water cleans up and promptly obtains full excystation clothing tangerine lobe.

Embodiment 3:

Peeling satsuma orange tangerine lobe is arranged in downwards on the horizontal shelf by the fruit core, see accompanying drawing, with pH 5.0, the 0.5% pectase aqueous solution is dipped into tangerine lobe fruit core segment, behind 20 ℃ of enzymolysis 6h, take out the tangerine lobe and put in pH 3.0, the 1% pectase aqueous solution, 45 ℃ are continued enzymolysis 40min, and taking-up tangerine lobe water cleans up and promptly obtains full excystation clothing tangerine lobe.

Embodiment 4:

Inject pH 5.0 from satsuma orange fruit fruit top center to the fruit in-core, 0.5% pectase aqueous solution 0.5mL, behind 45 ℃ of enzymolysis 3h, the peeling distinguish, obtain pretreated tangerine lobe, the tangerine lobe is put in pH 3.0, the 1% pectase aqueous solution, 50 ℃ are continued enzymolysis 40min, and taking-up tangerine lobe water cleans up and promptly obtains full excystation clothing tangerine lobe.
