Description

A kind of preparation method of high grafting degree pectin egg white product
Technical field
The invention belongs to the technical fields of food processing, are related to a kind of preparation method of high grafting degree pectin egg white product.
Background technique
Liquid eggs refers to liquid fresh egg, is birds, beasts and eggs through decladding of beating eggs, packaging refrigeration (or freezing) after centainly handling by egg liquid, The product consumed instead of fresh egg.Liquid egg product includes concentration liquid eggs, egg pulp, protein liquid, egg yolk liquid plus salt or sugared egg yolk Liquid, enzyme modification egg yolk liquid, the yellow and white mixed liquor of different proportion etc..Birds, beasts and eggs have the characteristics that high nutrition, easily absorb, with meat Class, grain, vegetables etc. are the same, occupy very high ratio in daily life.And by birds, beasts and eggs be processed into liquid eggs both improved it is additional Value is also convenient for transporting and consume, may advantageously facilitate egg product industrial expansion.Liquid eggs is basic on nutrition, flavor and functional characteristic The characteristic of fresh birds, beasts and eggs is remained, and quality is stablized.Liquid egg product health can save several weeks without harmful bacteria at refrigerated temperatures, It such as adds salt or sugar can be reserved for several moons in the case of freezing, reduce cost of labor, machinery, which is beaten eggs, improves yield rate, directly Apply to produce product, is easy transport and storage, there is no eggshell garbage problem.Chinese Poultry egg production position is at the forefront in the world, per capita Egg consumption has also been more than world average level, is egg production and consumption big country, but the birds, beasts and eggs consumption pattern in China is still with band shell Based on fresh egg, only liquid egg product is mainly also to be ignored needed for steaming in the processing of the products such as egg based on auxotype in the market The good function characteristic wanted.
Preparing the liquid egg product with high grafting degree by Maillard reaction at present has good adjusting product function special Property potentiality, in terms of being concentrated mainly on basic research for liquid eggs report, in terms of product initiative, CN106616508A is related to one The preparation method of kind high foaming egg liquid;CN106579403A is related to a kind of preparation method of high retentiveness egg liquid, but these sides Method ignores influence of the grafting degree to egg liquid product in industrial production just for the simple processing of egg liquid.2018, Zuo Yingxin Et al. have studied glycosylation have improvement result to protein function characteristic, improve the emulsifying activity and stable emulsifying of protein Property and dissolubility, so select sugar carry out functional characteristic change.Glycosylation can improve the functional characteristic of protein, And modification reaction does not need other chemical reagent, preparation method mainly uses dry heating method, and the consumed time is longer, and wet heating Just this defect is compensated for, has many advantages, such as that easy temperature control system, reaction time are short, but reacts more fierceness often along with formation Middle and later periods product is glycosylated, and influences functional characteristic and the safety of graft product, thus needs strictly to control during the reaction The factors such as temperature, time, pH value and substrate ratios processed.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of high grafting degree pectin egg white product, simple process, no later periods Product, Product Safety is high, improves egg white glycosylation grafting degree.
The purpose of the present invention is achieved through the following technical solutions:
A kind of preparation method of high grafting degree pectin egg white product, the specific steps are as follows:
(1) Fresh Egg is cleaned, decladding of beating eggs takes its egg white solution, discards yolk for egg white solution and sieves with 100 mesh sieve net Filtering, is diluted 10 times with water;
(2) ingredient is added, 6~10 parts of pectin, is stirred evenly, and carry out shearing homogeneous, shear rate 8000rpm is cut Cutting the time is 3 minutes;
(3) egg liquid after homogeneous is subjected to pH and is adjusted to 7~10;
(4) pectin egg liquid mixed liquor is subjected to heating 50min at 60~100 DEG C.
As more preferably technical solution of the invention: 8 parts of pectin described in step (2).
As more preferably technical solution of the invention: pH described in step (3) is adjusted to 8.5.
As more preferably technical solution of the invention: heating pectin egg liquid mixed liquor at 80 DEG C in step (4).
It has the advantages that
Preparation method provided by the invention improves egg white solution glycosylation grafting degree, and there is simple process to control well, without after Phase product, Product Safety are high.
The product of offer of the invention is not added with other food additives, and the uniform and stable property of liquid egg product is good, improves liquid eggs Functional character, meet national standard, can greatly meet the needs of consumer is to healthy food instantly.
It can store 12 days, meet in national standard about liquid eggs based article at 4 DEG C after product sterilization thoroughly provided by the invention Microbiological requirements.
The pectin that the present invention uses has preferable gelation, is carrying out glycosylated while improving egg white solution protein Stability.
