Description
Technical field
The present invention relates to a kind of new method of peeling green peel of walnut, specifically a kind of method of utilizing low temperature green peel of walnut to be removed again rascal after freezing by high temperature melt.
Background technology
As everyone knows, walnut is one of " world's four big dry fruits ", and high nutritive value and health-care effect are arranged, and simultaneously very high medical value is arranged also, is subjected to people's favor for a long time always.Along with rapid development of national economy, the improving constantly of people's living standard no longer satisfied edible and used dried walnut, and bright walnut also comes into the market in a large number, the edible and use for people.Yet the method for traditional peeling green peel of walnut is difficult to guarantee its fresh food quality.So far, the method for traditional peeling green peel of walnut mainly contains two kinds: stack retting takes off the rascal method and sprays ethephon (CEPHA) and accelerates the ripening and take off the rascal method.Its shortcoming is: stack retting takes off the rascal method: it is serious to rot; Time is long, generally needs about 7 days; Fruit stone is seriously polluted, and the walnut surface of taking off behind the rascal is dusky, and there is local pollution on part walnut surface, have in addition kernel take place rottenly, seriously influenced the product quality of walnut; As a large amount of productions, it pollutes and the deterioration rate of kernel also can be more serious.Spraying ethephon (CEPHA) accelerates the ripening and take off the rascal method: generally have two kinds, a kind of is to spray ethephon (CEPHA) after adopting, and another kind is to spray ethephon (CEPHA) before adopting; Spray ethephon (CEPHA) after adopting, be to be that the ethephon (CEPHA) of 3000～5000mg/kg soaked fruit 5 minutes with concentration, and then after spraying the ethephon (CEPHA) of going up this concentration, stack retting just begins to take off rascal about 5 days, though its time has shortened 2 days, but still longer, though its pollution rate and deterioration rate reduce also still higher (accounting for 1/3) to some extent; Spray ethephon (CEPHA) before adopting: be to be that the ethephon (CEPHA) of 800～1200mg/kg was sprayed on the walnut fruit face adopting in preceding 10 days, pluck again after 10 days, also need to carry out the system of macerating of a period of time afterwards with concentration.Spray ethephon (CEPHA) and accelerate the ripening and take off the rascal method, spray ethephon (CEPHA) before no matter adopting or after adopting, yet need to carry out stack retting; The whole rascal processing procedure of taking off, the time is long; After taking off rascal, ethephon (CEPHA) has certain residual quantity, the people is known from experience damage.
More than two kinds of method for peeling green peel all seriously influenced the product quality of walnut, and do not meet pollution-free food and requirements of green environmental protection; Thereby the commodity and the edibility of walnut have been influenced.
Summary of the invention
The purpose of this invention is to provide a kind of method of new peeling green peel of walnut, this method can be quick, a large amount of takes off rascal, takes off the shell surface clean behind the rascal, pollution-free; Color is beautiful; Kernel never degenerates; From skin rate height, easily decortication can be used for industrialization and takes off the rascal processing; Meet pollution-free food and requirements of green environmental protection.Fundamentally solve the difficult problem of the nice decortication of walnut, be particularly suited for fresh-eating walnut and take off the rascal processing.
In order to achieve the above object, the technical scheme that the present invention takes is: the walnut that maturation is good is chosen disease, insect pest fruit, carry out cryogenic freezing then, cryogenic temperature is-5～-25 ℃, treat the green peel of walnut deep colling after, be warming up to＞0 ℃ of thawing, remove rascal, through cleaning, airing, just can pack again, use for the user.
The thawing method can adopt nature to melt method or thawing modes such as hot blast or hot water.
Take off rascal and can adopt artificial rubbing to peel off, mode such as also can adopt mechanical oscillation or machinery to squeeze to get rid of.
Its technical process is: and the walnut fresh fruit selects → and sharp freezing → intensification melts → peels off rascal → cleaning → airing → finished product packing.
The walnut fresh fruit is selected: the walnut of the band rascal of maturation is selected, removed sick, insect pest fruit.
Sharp freezing: the walnut fresh fruit of picking out is carried out cryogenic freezing, and cryogenic temperature is-5～-25 ℃, makes the green peel of walnut deep colling;
Heat up to melt: the walnut of deep colling rascal is warming up to＞0 ℃ melt.The method of melting that heats up can adopt nature to melt; Also can adopt modes such as hot blast or hot water to melt fast, the temperature of hot blast, hot water generally is being advisable more than 30 ℃; The high more thawing time of temperature is short more.
Peel off rascal: the walnut after rascal is melted takes off rascal.Stripping means is a lot, can adopt that manual removal such as rubbing are peeled off etc.; Also can adopt the mode of mechanical stripping rascal, vibrate as moto-vibro screen and peel off, or machinery drum or hinge cage squeeze and to get rid of etc.
Clean: the walnut that will peel off behind the rascal cleans with clear water, cleans the rascal slag foam that goes to the walnut shell surface.
Airing: the walnut after will cleaning carries out airing, and walnut shell is dried, and the degree of drying should meet the pertinent regulations of walnut kind benevolence water content.
Finished product packing: the walnut that dries is packed, just can be sold and use for the user.
The present invention will carry out earlier freezing with the walnut of rascal to rascal, and then the thawing that heats up, and rascal just is easy to be stripped from, and has substituted traditional stack retting method.Because rascal is easy to deep colling, also be easy to after the deep colling melt, this has just shortened the time widely, and rascal also is easy to be stripped from, and brings great convenience to peeling off rascal; And whole process is not used chemical agent, does not have the residual of chemical agent, yet can not produce harm and environment is produced pollution human body when edible, meets the requirement of environmental protection and pollution-free food fully.Therefore, the present invention has quick, a large amount of rascal that takes off, and takes off the shell surface clean behind the rascal, and color is beautiful; Kernel never degenerates, and is pollution-free; From skin rate height, easily decortication; Meet characteristics such as pollution-free food and environment protection requirement.Fundamentally solve the difficult problem of the nice decortication of walnut, be particularly suited for fresh-eating walnut and take off the rascal processing.
