A salted duck egg production process based on a light salt technology comprises the following steps:

(E) and cooking and packaging: cooking the pickled eggs, and packaging.

It can be understood that the cleaning and the removing have the existing standards and equipment, the eggs are divided into different quality grades, and the poor removing is only needed, and if the cleaning is carried out, the cleaning can be carried out by adopting equipment such as a ZYF-JS1 egg cleaner, a ZYF-JS1-J3B egg cleaning production line and the like. In the classification aspect, classification is carried out according to the weight of the eggs so as to carry out differentiated process treatment later, and the classification can also be carried out by adopting the existing equipment such as a ZYF-J2L (R) egg classifier, a ZYF-D3(6) -3T egg classifier and the like. The yellow-white mixing is to mix the egg white and the egg white by using the mixing device. The food bag can be packaged in vacuum, or can be contained in a container such as a plate, a bowl, a basket, a bottle and the like, and the food bag can be selected reasonably according to requirements according to local conditions.

Further, eggs are classified into six grades of S-, S +, M-, M +, L-and L +, and the weight of each grade of single egg is respectively as follows: s < - > is less than 55g, S < + > is less than or equal to 55g and less than or equal to 65g, M < - > is less than or equal to 65g and less than or equal to 75g, M < + > is less than or equal to 75g and less than or equal to 85g, L < - > is less than or equal to 85g and less than or equal to 95g, and L < + > is more than; selecting eggs of four grades of S +, M-, M + and L-for later use. It can be understood that eggs which are too small, too large are difficult to process and difficult to ensure the effect, so that the eggs are reserved for other purposes, and only eggs with four grades of S +, M-, M + and L-are selected for standby.

Further, the step (D) of separately pickling according to different grades includes: the salt content in the salting material corresponding to the eggs with the grades of S +, M-, M + and L-is gradually increased, and the increasing value is gradually reduced; and/or the salting time of eggs corresponding to the grades S +, M-, M + and L-is gradually increased and the incremental value is gradually reduced. It is understood that the marinade can be the simplest salt water, and various seasonings such as high-degree wine, cooking wine, vinasse, spices, vanilla, hot pepper and the like can be added, and the seasonings are reasonably selected according to the appetite requirement, wherein the salt content which is most related to oil production, sand formation, taste and the like is mainly considered.

Further, the step (D) of separately pickling according to different grades includes: the salt content of the salting material corresponding to the S +, M-, M + and L-eggs in the grades is 10.5 +/-0.4% (wt), 13.5 +/-0.4% (wt), 15.5 +/-0.4% (wt) and 16.5 +/-0.4% (wt) respectively; and/or the salting time lengths corresponding to the grades of S +, M-, M + and L-eggs are respectively T +7 +/-0.5 days, T +10 +/-0.5 days, T +12 +/-0.5 days and T +13 +/-0.5 days, wherein T is a variation parameter, and influence factors of the variation parameter comprise season, air temperature, altitude and air pressure. It can be understood that because the interior is yellow and white, and the original yolk substance exists at the position close to the eggshell, the oil and sand are easy to produce, the treatment period is greatly shortened, and the salt consumption is greatly reduced. T is reasonably changed according to the season, air temperature, altitude and air pressure of a manufacturing place, for example, T is 0 in summer, 3-5 in spring and autumn, and 8-10 in winter. The air temperature, air pressure, altitude and the like are similar, and the main consideration is the difficulty of salt entering the egg product, so that the salting time is short and the salt concentration is low when the salt enters the egg product easily, and conversely, the salting time is long and the salt concentration is high.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
