Abstract

The present invention discloses a preservation method of fresh eggs. The preservation method of the fresh eggs comprises the following steps: collected fresh eggs are fully soaked in a 25%-35% sodiumchloride solution for 5-7 min, a soaking water temperature is 15-19 DEG C, and blood spots, feces, soil and other dirt on surfaces of fresh egg shells are softened; and the residue blood spots, feces,soil and other dirt on the surfaces of the fresh egg shells of the soaked fresh eggs are brushed away using a brusher. The method can effectively remove the blood spots, feces, soil and other dirt onthe surfaces of the fresh egg shells, the fresh eggs are successively disinfected using two methods of peroxyacetic acid solution spraying and ultraviolet radiation, and finally a preservative applying method is used. A film-applying method uses a macromolecular compound with a film-forming function as the preservative, one of three of chitosan, polyvinyl alcohol and liquid paraffin is applied onthe surfaces of the egg shells to form an artificial protective film on the egg shells, air-pores of the egg shells are blocked, and escape of carbon dioxide and loss of moisture from the eggs can bereduced.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a fresh egg preservation method. Background technique [0002] Eggs, also known as chicken eggs and chicken eggs, are eggs produced by hens. There is a hard shell on the outside, and there are air cells, egg white and yolk inside. Rich in cholesterol and rich in nutrition, an egg weighs about 50 grams and contains 7 grams of protein. The amino acid ratio of egg protein is very suitable for the physiological needs of the human body, easy to be absorbed by the body, the utilization rate is as high as 98%, and the nutritional value is very high. It is one of the foods that humans often eat. According to analysis, every 100 grams of eggs contains 12.8 grams of protein, mainly ovalbumin and ovalbumin, which contain 8 kinds of amino acids necessary for the human body, and are very similar to the composition of human protein. The absorption rate of egg protein by the human bo...
