Description
Technical Field
The invention belongs to the technical field of food science, relates to an egg pickling system, and particularly relates to a system and a method for quickly making reproduced eggs by a medium-high voltage electric field method.
Background
The reproduced egg is an egg product without changing the shape of fresh eggs after salt, alkali, vinasse, marinating and frying, and mainly comprises preserved eggs, salted eggs, vinasse eggs, marinated eggs and various cooked eggs. The reproduced eggs needing to be processed by the pickling process mainly comprise preserved eggs, salted preserved eggs and pickled eggs, wherein the preserved eggs, the salted eggs and the salted preserved eggs are processed most widely.
The salted egg has unique flavor and convenient eating, and is mainly prepared by salting with salt. The salted egg yolk can be used as raw material for processing other foods, such as: moon cakes, rice dumplings and the like can also be used as raw materials of certain dishes. The pickling principle is that Na in the pickling liquid + And Cl & lt- & gt continuously enters the duck eggs under the action of osmotic pressure, so that water in the egg yolks is gradually lost, the original uniformly distributed emulsified fine fat beads are gradually separated and separated out and are aggregated into obvious oil liquid or oil drops, and the egg yolks are in a rich and moist oil-out state, so that the unique and delicious flavor of the salted eggs is created. The period for processing the salted eggs by the traditional method is generally 30-40 days, and the salting period is longer. The salted eggs processed by the traditional method have the following problems: 1. because the pickling period is long, a large amount of capital of an enterprise is accumulated on the salted eggs in the pickling process, and once the quality of the products in the pickling process is problematic, the enterprise faces serious loss; 2. the traditional salted egg processing cycle is too long, and the microbial pollution is serious in the processing process. Although the subsequent sterilization step is carried out, under the action of microorganisms, the protein in the eggs is decomposed into amine substances harmful to human bodies and generates hydrogen sulfide, and the finished product egg yolks after cooking have a 'black ring' phenomenon, so that the quality and sales of the product are influenced.
Preserved eggs are special reproduced egg products in China, and the yield of the preserved eggs is the top of egg products in China. Preserved eggs have a long processing history in China, and have the advantages of rich nutrition, unique flavor and the like. Besides being eaten directly, the preserved eggs can also be used for processing Chinese special dishes such as: preserved egg bean curd, preserved egg and lean meat porridge and the like are well received by consumers. Preserved egg is made up of duck's egg and egg through preparing soup (mud) with lime, alkali and salt or preparing pickling liquid with sodium hydroxide. In the pickling process, OH & lt- & gt in the pickling liquid enters the poultry egg, so that egg white protein is denatured to form dark brown gel. Preserved eggs processed by the traditional method have the following problems: 1. the traditional preserved egg pickling method has long pickling period, generally about 40-90 days, is open-type pickling, is easy to volatilize alkali liquor, has harm to the respiratory tract and the environment of operators during manual operation, and needs to be improved urgently in production environment; 2. due to the long pickling period, a large amount of capital of enterprises is accumulated on the preserved eggs in the pickling process, and once the quality of products in the pickling process is poor, the enterprises are subjected to serious loss and even failure.
The salted preserved egg is a unique delicious food of Guangan in Sichuan, and is prepared by firstly putting spices into an iron pan for boiling, cooling, then putting salt into the iron pan for preparing a pickling solution, putting the cleaned eggs into the pickling solution for pickling, taking out the eggs after soaking for 17-21 days, and sterilizing. The salted preserved egg combines the advantages of preserved eggs and salted eggs, and the egg is not only a delicious food for wine, but also one of the best dishes for breakfast. There is currently less research on the process of salted preserved eggs.
