Method for curing salted eggs

Abstract

The invention provides a method for curing salted eggs. A salinity gradient curing method is adopted in the method, the salt concentration of the curing solution is reduced stage by stage during curing fresh poultry eggs, the eggs are soaked into clear water at the later stage of curing, and the cleaned salted eggs are packed in vacuum and sterilized. The egg white and the yolk of the salted eggsobtained by using the method have uniform salinity, and the yolk is golden yellow and has high oil outlet rate. The method is simple, has low production cost, and has good production and development prospect.

Description

technical field

[0001] The invention provides a method for pickling salted eggs and belongs to the field of food processing. Background technique

[0002] Salted egg, also known as salted egg, salted egg, or flavored egg, is a re-product with special flavor and convenient consumption. As early as 1600 years ago, there were records in China of storing poultry eggs in salt water, and it gradually evolved into the method of processing salted eggs today. Salted eggs are regenerated eggs made from fresh duck, chicken and other poultry eggs, which are marinated with salt water or salty pure yellow mud, red mud, plant ash, etc. The most important method of salted egg processing is salt water immersion, that is, immersing eggs in a certain concentration of salt water. Due to the difference in the chemical composition of the egg white and egg yolk, their resistance to the transfer of water and salt is different. Compared with poultry egg yolk, poultry egg protein contains more...

Embodiment 1

[0049] Raw materials of fresh poultry eggs: select fresh poultry eggs, sort, grade, wash, and dry for later use;

[0050]The first pickling: prepare a 25% concentration of pickling solution, put the graded and washed fresh eggs into the pickling box (tank), make the fresh eggs completely submerged in the pickling solution, and marinate for 15 days. Drain the first pickling liquid into the pickling liquid recovery tank, and recycle the pickling liquid for reuse; inject the second pickling liquid into the pickling box: prepare a 15% concentration of pickling liquid, so that the fresh eggs are completely submerged In the pickling liquid, marinate for 10 days. Drain the second pickling liquid into the pickling liquid recovery pool for recycling and reuse of the pickling liquid; inject three pickling liquids into the pickling box: prepare a 5% concentration of pickling liquid to make fresh eggs completely Immerse in the pickling liquid and marinate for 5 days; discharge the third ...

[0053] The first pickling: prepare a 25% concentration of pickling solution, put the graded and washed fresh eggs into the pickling box (tank), so that the fresh eggs are completely submerged in the pickling solution, and marinate for 20 days. Discharge the first pickling liquid into the pickling liquid recovery pool for recycling and reuse of the pickling liquid; inject the second pickling liquid into the pickling box: prepare a 15% concentration of pickling liquid to fully submerge the fresh eggs In the pickling liquid, marinate for 5 days. Discharge the second pickling liquid into the pickling liquid recovery pool for recycling and reuse of the pickling liquid; Inject three pickling liquids into the pickling box: prepare a 5% concentration of pickling liquid to make all fresh eggs Immerse in the pickling liquid and marinate for 5 days; discharge the third pick...
