Pickling method for fast pickling salted duck eggs in laser etching assistance way and implementation system thereof

Abstract

The invention relates to a pickling method for fast pickling salted duck eggs in a laser etching assistance way. The method comprises the following steps of (1) cleaning and grading of fresh eggs; (2)preparation of saturated salt solution; (3) laser etching of fresh eggs: etching a plurality of points on the surfaces of egg shells by a laser etching machine with the etching depth no more than 1 / 3to 1 / 2 of the egg shell thickness; (4) pickling of fresh eggs; (5) cleaning and drying: cleaning the pickled salted eggs by clean water to remove salt stains on the surfaces of the egg shells; performing drying; (6) packaging: performing vacuum independent packaging on the dried salted eggs by a vacuum packaging machine; (7) sterilization and cooking: performing high-temperature steam sterilization on the salted eggs subjected to vacuum packaging; meanwhile, cooking the eggs to the cooked states to obtain the salted duck eggs with proper salty and delicious mouthfeel. The method has the advantages that laser is used for pretreating the egg shells; the seepage area of sodium chloride solution is greatly increased; the seepage speed of the sodium chloride solution is accelerated; the pickling time of salted eggs is greatly shortened, so that the salt degree distribution is uniform; the egg yolk oil yield, the product uniformity and the salted egg quality are improved.

Description

technical field [0001] The invention belongs to the technical field of food and relates to the preparation of salted eggs, in particular to a laser etching-assisted pickling method for quickly pickling salted duck eggs and an implementation system thereof. Background technique [0002] Salted eggs, also known as salted eggs, salted eggs, and flavored eggs, have the characteristics of unique flavor, convenient eating, and rich nutrition. They are traditional characteristic egg products in my country and have a wide market demand. The traditional pickling methods of salted eggs mainly include salt water immersion method, salt mud coating method and grass ash method. Among them, the salt water immersion method has the characteristics of fast pickling speed, simple operation, hygienic convenience, and reusable salt water after treatment. In the production of enterprises, the method of pickling with high-concentration brine is usually used. Salt concentration and pickling temper...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art, aiming at the disadvantages that the salt and pickling spice liquid cannot quickly pass through the egg shell, penetrate into the shell, and the salinity distribution is uneven, and provide a laser etching-assisted rapid pickling of salted duck eggs The pickling method and its implementation system, the method pre-treat poultry egg shells with laser, greatly increase the penetration area of ​​sodium chloride solution, accelerate the penetration rate of sodium chloride solution, greatly shorten the salting time of salted eggs, Make the salinity distribution uniform, improve the oil yield of egg yolk, the uniformity of the product, and improve the quality of salted eggs
