Description
Technical field
The invention belongs to garden stuff processing technical field, be specifically related to the barking method of a kind of fruit and vegerable.
Background technology
Fruit and vegerable peeling is requisite operation in some fruit and vegetable product courses of processing, and the quality of peeling is by direct shadow
Ring the quality of goods, the acceptable degree of consumer and the economic benefit of fruit and vegerable intensive processing.The most traditional fruit
Vegetables barking method mainly includes the peeling of machine barking, steam peeling, chemical peeling, hot water, freezing peeling.Machine
Tool peeling is to use more a kind of peeled technology at present, and technology maturation, production efficiency is high, commonly used and Herba Marsileae Quadrifoliae
Really, pear and other fruits.Steam peeling efficiency is high, and product yield is high, can cause product surface heat to a certain extent
Damage, be not suitable for the fruit of the easy oxidizing brown stains such as Fructus Mali pumilae.Chemical peeling is to use dipping by lye fruit and vegerable, really
Vegetables surface separates through the corrosion of alkali liquor certain time, fruit pulp, thus reaches the effect of peeling.But it is chemical
Peeling, owing to causing pulp organization to disintegrate, remove the peel many, consumption greatly, and sarcocarp rough surface is uneven, process
Improper meeting causes sarcocarp serious discoloration, so chemical peeling not only reduces the utilization rate of raw material, and affects product
Quality.Simultaneously because the residual of chemical reagent is discharged with a large amount of in the course of processing, polluted product also severe contamination
Environment.Hot water peeling is the purpose being immersed in boiling water by mellow fruit and having reached fruit and vegerable peeling, the method
There are certain requirements fruit maturity, crude fruit cannot be used for the method and removes the peel.Freezing peeling is main to be used
In Fructus Vitis viniferae peeling stalk, the existing relevant report of Japan.
But above-mentioned barking method or have certain injury to fruit and vegerable self, causes peeling the adaptability of big product to be lost relatively
Weak, poor to the decortication effect of some fruit and vegerable.The peeling of fresh chilli is imitated by the most above-mentioned all of barking method
Fruit is the most poor, and this limits the exploitation of some fruit and vegerable new product to a certain extent.
Summary of the invention
For solving above-mentioned deficiency of the prior art, it is an object of the invention to provide a kind of fruit vegetable peeling side
Method, the strong adaptability of this barking method, the peeling of multiple fruit and vegerable can be simultaneously used for, product loss is little, peeling effect
Rate is high.The present invention is achieved through the following technical solutions for achieving the above object.
The barking method of a kind of fruit and vegerable, specifically includes following steps: (1) fruit and vegerable clean: by fruit and vegerable to be removed the peel
Clean up, remove the impurity such as epidermis earth;(2) humid heat treatment: it is damp and hot that the fruit and vegerable after cleaning are placed in constant temperature
In case, adjusting temperature and be 45-90 DEG C, relative humidity is 60%-90%, processes 10-50min;(3) vacuum takes off
Skin: fruit and vegerable are immediately placed in vacuum tank after humid heat treatment while hot, suction is 0.09-0.098MPa, very
Empty room temperature is 15-30 DEG C, maintains vacuum environment 30-90s, and in 2s, instantaneous vacuum breaker degree makes vacuum chamber afterwards
Interior recovery to atmospheric pressure state, atmospheric pressure state i.e. normal atmosphere 101.325kPa, make fruit and vegerable skin breakage;(4)
Washing: the fruit and vegerable water after application of vacuum rinses out epidermis.
As optimal technical scheme, in described step (2), humid heat treatment temperature is 55-80 DEG C, and relative humidity is
70%-80%, the process time is 20-30min.
As optimal technical scheme, in described step (3), during vacuum decortication, the temperature in vacuum tank maintains
Between 20-25 DEG C.
As preferably, described fruit and vegerable include Fructus Capsici, Fructus Lycopersici esculenti, Rhizoma Solani tuber osi, Radix Ipomoeae.
The fruit and vegerable that the present invention uses humid heat treatment to treat decortication carry out the pre-heat treatment, can be according to fruit and vegetable food ripening journey
The processing of degree needs to control temperature and is 45-90 DEG C, during humid heat treatment the cell of fruit and vegerable fully absorb moisture and
Expand.In vacuum exfoliating process, vacuum indoor pressure reduces rapidly, and fruit and vegerable epidermis inhales water saturated intracellular water
Divide rapid explosive evaporation, make fruit and vegerable epidermal tissue rupture.Vacuum process is carried out at a lower temperature, causes fruit and vegerable
Epidermis and internal bigger thermograde, epidermis drastically shrinks, interior detail intracellular moisture transpiration, and fruit and vegerable epidermis is thin
Born of the same parents rupture under the dual function of inside and outside bigger thermograde and inside and outside bigger pressure.Meanwhile, by instantaneous broken
Vacuum is also recovered to atmospheric pressure state, and external and internal pressure change the most suddenly makes fruit and vegerable epidermis burst further,
Fruit and vegerable Skin shrinkage and be kept completely separate with sarcocarp.
Without chemical substance in processing procedure of the present invention, processing procedure is safe and nontoxic, environmental protection, by self
Effect make skin breakage, the damage to fruit and vegerable self is less, product loss little.
