Description

Method for quickly pickling black-circle-free low-salt salted eggs
Technical Field
The invention relates to a method for pickling salted eggs, in particular to a method for quickly pickling low-salt salted eggs without black circles.
Background
China is a big country for producing and consuming poultry eggs, and the yield is the first in the world. At present, the total egg production amount in China is 2600 ten thousand tons, which accounts for more than 40% of the total world production, and the annual fresh duck egg production amount in China is 350 ten thousand tons. The salted egg is a main product processed from fresh duck eggs in China, has unique flavor, convenient eating, rich nutrition, rich protein and various amino acids required by human bodies and various mineral substances such as calcium, phosphorus, iron and the like, has delicious taste and is suitable for people of all ages. The salted eggs occupy a great proportion in the livestock product processing industry in China, are also main commodities for livestock and poultry product export in China, and have the first trade quantity in the world.
The salt content in the eggs is increased due to the osmosis of the salt, and the inorganic salt in the eggs is slightly increased. The fat in the raw egg yolk is combined with the protein, so that the egg yolk does not contain oil, the pickling time is long, the protein can be denatured and is separated from the fat, the fat is gathered together to form egg yolk oil, the egg yolk contains reddish yellow ovalbumin and carotene, the egg yolk is reddish yellow when being dissolved in the egg yolk oil, the sensory properties of the salted duck eggs are improved, and the salted duck egg oil is a good pickling mark.
In the traditional processing technology generally adopted in China at present, if the low salt content of egg white is realized, the pickling time of the salted duck eggs is shortened, the pickling time is shortened, the fat and the egg white of egg yolk cannot be effectively separated, the egg yolk is oil-free or has low oil content, and the inherent characteristics of the salted duck eggs with the characteristics of freshness, fineness, tenderness, looseness, sand and oil cannot be achieved; if the oil content of the egg yolk is increased, the pickling time is prolonged, the salt content in the egg white is high, and the taste is salty. The salted eggs prepared by the traditional high-salt salting processing technology are high-salt products, are slightly salty, have poor taste and unstable quality, and can not realize low salt of yolk and egg white at the same time. Meanwhile, the traditional salting method has long salting time, generally about 60 days, and after the salted eggs are cooked to be made into vacuum-packaged salted eggs, the black yolk ring rate is high, and the product sale is influenced although the black yolk ring does not hinder the use.
At present, the consumption trend is low-salt and healthy food, and consumers are willing to accept low-salt oil yellow salted duck eggs when eating the low-salt oil yellow salted duck eggs. High-salt food has great concern for consumption because of permanent damage to certain organs (such as kidney, cardiovascular system, etc.) of human body due to high salinity. When people eat salted duck eggs produced by the traditional one-time salting process, people usually eat only yolk without egg white due to high salt content of the egg white, and the salted egg white with high salt content is discarded, so that great resource waste is caused. Therefore, the development of a new product of salted duck eggs which is safe, healthy and green becomes a necessity for the sustainable development of the salted duck egg industry.
