Description
Technical field
The present invention relates to food processing technology field, it is specifically related to a kind of liquid eggs and its processing method.
Background technique
Liquid eggs be by fresh birds, beasts and eggs after a series of working processes egg liquid product obtained, egg white solution, yolk can be divided into
Liquid, egg pulp.Liquid eggs can effectively solve the problems, such as frangible shell egg, difficult transport and difficult storage, simultaneously because aseptic packaging is more
It is safe and healthy, it is more convenient to use.Currently, liquid egg product is quite universal in the U.S., Europe and Japan and other countries, liquid
Egg products processing capacity accounts for about the 30%-40% of its fresh egg total amount, however China, as the first big country of egg production, birds, beasts and eggs yield accounts for
45% or so of world's share, but the ratio of deep processing egg product only accounts for the 0.7%-1% of birds, beasts and eggs total amount.Significant problem is liquid
The production of egg encounters some bottlenecks: first, the sterilization technology of liquid eggs, manufacturer generallys use pasteurization, but egg white
Heat resistance is lower, is easy heated denaturalization, and sterilization intensity influences the functional character and nutritive value of egg white;Second, the guarantor of liquid eggs
The matter phase is usually within one month, in addition the time loss of factory and transport, time of the liquid egg product on Sales Channel are not grown.
Summary of the invention
The first object of the present invention is to provide emulsibility, the viscosity, gel of a kind of extension liquid eggs shelf-life and raising liquid eggs
Functional processing method such as hardness.
The second object of the present invention is to provide a kind of liquid eggs obtained by above-mentioned processing method.
In order to realize that the first above-mentioned purpose, the present invention provide a kind of processing method of liquid eggs, comprising the following steps: (1)
Fresh birds, beasts and eggs are taken, its egg liquid is taken after decladding;(2) hydroxypropyl methyl cellulose and pectin are added into egg liquid, after mixing evenly
Homogeneous is carried out, stable gluey mixing egg liquid is formed;(3) pasteurized process is carried out to the mixing egg liquid that step (2) obtain;
(4) it will be sealed after the container vacuum-pumping of the mixing egg liquid after pasteurized process in step (3), then advertise nothing into mixing egg liquid
Bacterium nitrogen;(5) the mixing egg liquid for obtaining step (4) is bottled, and sterile nitrogen is filled with into bottle, by bottle mouth sealing, at 0-4 DEG C
It saves.
By above scheme as it can be seen that hydroxypropyl methyl cellulose is a kind of very strong polysaccharide of surface-active, can be dissolved in water and
Partial solvent has good water-retaining property and stronger thickening capabilities, has preferable biocompatibility;Pectin, which is used as, to be had solely
A kind of water-soluble polysaccharide of special bioactivity can play synergistic effect with hydroxypropyl methyl cellulose, improve the emulsification of liquid eggs
The functional characters such as property, viscosity, gelation.Liquid eggs is filled by sterile nitrogen, greatly reduces the oxygen content in liquid eggs,
The shelf-life of liquid eggs is effectively extended, liquid eggs of the invention can be with stored refrigerated 80 days to 85 days at 4 DEG C.
Further embodiment is, in step (2), the mass ratio of hydroxypropyl methyl cellulose and egg liquid be 0.4% to
0.8%, the mass ratio of pectin and egg liquid is 0.3% to 0.7%.
As it can be seen that a small amount of hydroxypropyl methyl cellulose and pectin, which is added, can reach the emulsibility for improving liquid eggs, viscosity, coagulate
The purpose of the functional characters such as colloidality has effectively kept the original protein function characteristic of liquid eggs.
Preferably, the mass ratio of hydroxypropyl methyl cellulose and egg liquid is 0.4%, and the mass ratio of pectin and egg liquid is
0.5%.
Preferably, the mass ratio of hydroxypropyl methyl cellulose and egg liquid is 0.6%, and the mass ratio of pectin and egg liquid is
0.3%.
Preferably, hydroxypropyl methyl cellulose is in powdered.
Preferably, pectin is in powdered.
Further scheme is that pectin is low-ester pectin, and the esterification degree of pectin is 25%.
Further embodiment is that the egg liquid in step (1) is egg white solution, egg yolk liquid or egg pulp.
Further embodiment is, in step (5), after being filled with sterile nitrogen into bottle, the volumetric concentration of the nitrogen in bottle is not
Lower than 98%.
In order to realize the second above-mentioned purpose, liquid eggs provided by the invention is obtained according to above-mentioned processing method.
