Abstract
The invention discloses a kind of apple peel methods, comprising the following steps: (1) apple to be removed the peel is freezed to 15~20d under the conditions of -20~-15 DEG C of temperature；(2) apple after freezing is immersed in cold water, is thawed, then take out apple and drained away the water；(3) it will be put into lye dipping agent in the apple after defrosting, 5~6min of peeling processing carried out under the conditions of 50~70 DEG C of temperature；(4) cleaning is by removing the peel apple grunt 2~3 times handled.The present invention by freezing the processing mode thawed again in advance to apple progress, so that apple skin and pulp carry out initial gross separation under physical condition, while evacuated, and enhances the affinity of itself and lye dipping agent by the compactness of apple skin.Peeling processing is carried out to apple using the present invention, peeling, peeling rate 100% can be completed under the conditions of lower temperature, and be not easy brown stain, product appearance is good, has reached the processing request of food.
Description
Technical field
The present invention relates to a kind of barking methods of apple, belong to food processing technology field.
Technical background
When fruit process is at can or preserved fruit, removal epidermis is had to, and the fruit as apple, very due to its skin
It is thin, it can not remove by hand, and can only be removed the peel using decorticating agent, traditional decorticating agent is lye, and peeling loss is very big, and
It is not affine to lye since the wax coat of apple is finer and close, so that lye is difficult to permeate, and the applied at elevated temperature environment of lye,
It is be easy to cause the brown stain of apple, its original flavor is lost, the requirement of processed food is not achieved.
Summary of the invention
To solve the deficiencies in the prior art, that the purpose of the present invention is to provide a kind of is low using temperature, peeling is high-efficient
Apple peel method.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions:
A kind of apple peel method, which comprises the following steps:
(1) it freezes: by apple to be removed the peel under the conditions of -20~-15 DEG C of temperature, freezing 15-20d；
(2) it thaws: the apple after step (1) freezing being immersed in cold water, is thawed, be dipped to the surface formation of apple
Ice clothing melts completely, at this point, taking out apple, and drains away the water；
(3) it removes the peel: will be put into lye dipping agent in apple described in step (2), carried out under the conditions of 50~70 DEG C of temperature
5~6min of peeling processing；
(4) clean: the apple grunt by step (3) by peeling processing carries out clear water and washs 2~3 times, obtains product.
Further, the lye dipping agent includes following components, and the mass percentage of each component are as follows: caustic alkali 3
~5%；Sodium chloride 0.2~0.4%, sodium carbonate 0.05~0.1% and excess water.
And the caustic potash is sodium hydroxide or potassium hydroxide.
The beneficial effects of the present invention are: the present invention freezes the processing mode thawed again by carrying out to apple in advance, so that
Apple skin and pulp carry out initial gross separation under physical condition, while the compactness of apple skin is evacuated so that its with
The affinity of lye dipping agent enhances.Peeling processing is carried out to apple using barking method of the present invention, can 50~
Peeling to be completed under the conditions of 70 DEG C of temperature, realizes that peeling rate is 100% in 5~6min, and be not easy brown stain, product appearance is good,
The processing request of food is reached.
Specific embodiment
The present invention is specifically described below in conjunction with specific embodiment:

Ice clothing melts completely, at this point, taking out apple, and drains away the water；
(3) it removes the peel: will be put into lye dipping agent in apple described in step (2), removed the peel under the conditions of 60 DEG C of temperature
Handle 6min；
(4) clean: the apple grunt by step (3) by peeling processing carries out clear water and washs 2 times, obtains product.
Wherein, the lye dipping agent includes following components, and the mass percentage of each component are as follows: sodium hydroxide
