Abstract

The invention discloses a preparation method of modified recombinant egg white, belonging to the technical field of food processing.

Description

Preparation method of modified recombinant egg white liquid
Technical Field
The invention belongs to the technical field of egg product processing, and particularly relates to a preparation method of modified recombinant egg white liquid.
Background
The egg white is the main component of the eggs, the weight of the egg white accounts for 45-60% of the whole egg, and the weight of the egg white accounts for 45-58% of the whole egg. The egg white has high nutritive value, protein accounts for more than 90% of the dry basis weight, and the balance is lipid, vitamins, minerals and the like. The egg white protein is high-quality protein suitable for human body absorption, and the absorption utilization rate is as high as 99.6%. In addition, egg white has various functional characteristics, such as foamability, emulsibility, gelation property and the like, wherein the gelation property is most widely applied in food industrial production. Egg white has good gelling properties, and is widely used as a raw material for food processing, not only to improve the texture and form of food, but also to improve the water-retaining property, thickening property, cohesiveness and the like of food, and is widely used in meat paste, fish paste, flour products and the like.
The salted duck egg white is a byproduct for producing salted egg yolk, and has higher salt content, so that the salted duck egg white cannot be fully and reasonably utilized. Except that a few raw materials are used for processing flour products such as feed, biscuits, noodles and the like, a large amount of the raw materials are directly discarded, so that the high-quality protein resource is greatly wasted, and the serious pollution is brought to the surrounding environment and water sources. The protein content of the salted duck egg white is the same as that of fresh egg white, but the functional characteristics of the salted duck egg white are influenced to a certain extent due to the action of high salt. At present, the high-value utilization of the salted duck egg white mainly adopts enzymolysis and desalination processes, including treatment modes of enzymolysis and desalination, desalting firstly and then enzymolysis and direct desalination. Generally speaking, desalination methods such as ultrafiltration and isoelectric point generally have the problems of high cost and low yield, and the high salt content of the salted egg white causes corrosion of processing equipment. On the premise of not performing desalination treatment, the functional characteristics of the salted duck egg white are improved, so that the salted duck egg white is paid more and more attention and attention on efficient value-added utilization.
