Problems solved by technology

However, the production process of non-spot preserved eggs has not been popularized so far. The main reason is that there are two technical problems in the production of non-spot preserved eggs. Big heart, poor quality and storage performance

Embodiment 1

[0025] A method for producing zinc-enriched and spot-free preserved eggs. The duck eggs are screened and put into a pickling vat. Salt, tea powder, sodium hydroxide, zinc sulfate, and ferrous sulfate are added to the water, stirred and then poured into the pickling vat. For the pickling of preserved eggs, the pickling period is divided into three periods: front, middle, and last. Set the pickling temperature and ambient humidity in the early pickling tank for pickling. Sodium concentration, increase the pickling temperature in the pickling vat, adjust the ambient humidity, and continue to pickle. During the later pickling, increase the concentration of sodium hydroxide in the feed liquid, reduce the pickling temperature in the vat, and adjust the ambient humidity , continue to pickle, after the pickling is completed, the preserved eggs are cleaned and packaged, specifically including the following steps:

Abstract

A zinc-rich spotless preserved egg production method belongs to the technical field of food processing. The preserved egg production method includes the following steps: 1, selecting eggs, and grading; 2, preparing a feed liquid, 3, filling; 4, carrying out early stage preservation; 5, carrying out middle stage preservation; 6, carrying out later stage preservation; 7, cleaning, and disinfecting; and 8, drying, and packaging. The method is characterized in that zinc sulfate and ferrous sulfate are added to the feed liquid, and the concentration of sodium hydroxide in the feed liquid and the preserving temperature of in different preserving stages are changed, the addition of the soluble zinc salt in the production of preserved eggs makes the shells of the finished preserved eggs have no black spots and allows the eggs to be easily identified due to no lead, and a detection result shows that the content of zinc element in the finished preserved eggs is above 10 times that of common preserved eggs, so the preserved eggs obtained in the invention are beautiful and can supplement zinc needed by human bodies; and the good cooperative control of the concentration of sodium hydroxide in the feed liquid and the preserving temperature in different preserving stages substantially reduces the phenomena of alkali dissolved head, much yellowing and large soft yolk, improves the yield, the quality and the storage property of the preserved eggs, and makes the processed preserved eggs have good flavor.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a method for producing spot-free preserved eggs. Background technique [0002] Preserved eggs, also known as preserved eggs, have a long history of processing in my country. They are unique traditional egg products in my country and are favored by consumers at home and abroad. In recent years, with the growth of the national economy and the improvement of people's living standards, the traditional preserved egg production process has made great progress, for example: copper sulfate is used to replace lead oxide in the traditional feed solution to reduce the content of harmful element lead; The production efficiency of preserved egg processing is further improved by the material cleaning method instead of the gray bag method; the raw material waste and environmental pollution in the preserved egg production are reduced by coordinating the processing of new and old material...
