Manufacturing method of lead-free preserved eggs

Abstract

The invention discloses a manufacturing method of lead-free preserved eggs and belongs to the technical field of poultry egg processing. The manufacturing method comprises the following steps: step 1, preparing preservation liquid: (1) preparing the preservation liquid from the following raw materials in parts by weight: 100 to 120 parts of a saturated sodium carbonate water solution, 10 to 20 parts of orchid flower and 20 to 30 parts of dried sea grass; (2) pouring the orchid flowers and the dried sea grass into the saturated sodium carbonate water solution and heating to 50 DEG C to 60 DEG C; keeping the temperature for 20min to 30min and filtering impurities to prepare a mixed solution; (3) after cooling the mixed solution to 15 DEG C to 20 DEG C, adding calcium hydroxide into the mixed solution until the calcium hydroxide and sodium carbonate completely react to prepare the preservation liquid; step 2, putting complete poultry eggs, which are washed, into the preservation liquid and preserving for 15 days to 20 days; keeping the preservation liquid completely immersing the poultry eggs in a preserving process; step 3, injecting carbon dioxide to the bottom of the preservation liquid at a ratio of adding 2g of the carbon dioxide into one liter of the preservation liquid, and sealing and preserving for 20 days to 25 days; step 4, covering mud on the preserved eggs. According to the manufacturing method provided by the invention, the preservation liquid and a preservation method of the preserved eggs are changed, so that the processed preserved eggs have a unique flavor and are good for health.

Description

technical field [0001] The invention belongs to the technical field of poultry egg processing, in particular to a method for making lead-free preserved eggs. Background technique [0002] After the preserved egg matures, its protein is tan or green-brown gel, elastic, and there are pine needle-like crystal patterns in the protein gel, so it is also called preserved egg. The egg yolks are solidified solids of dark green, grass green, and brown in different shades. The colors are diverse and changeable, so they are also called colored eggs and changed eggs. Preserved eggs mainly include soft-boiled preserved eggs and hard-boiled preserved eggs. Soft-boiled preserved eggs have the advantages of good palatability and convenient operation, and are the main products of my country's preserved egg processing industry. Preserved egg processing has a long history in my country and is a unique traditional egg product in my country. It has the advantages of beautiful color, bright lust...

However, the "copper method" or "copper-zinc mixed method" has brought in a large amount of copper elements. Although copper is one of the essential elements for the human body, the phenomenon of copper deficiency in the Chinese population is rare, and there is a phenomenon of "copper poisoning" instead. The method of making preserved eggs will undoubtedly cause a large amount of copper to accumulate in the human body, thus affecting people's health
