Goose eggs are rich in nutrients, but improper preservation, it is easy to cause corruption and deterioration. In addition, the production of goose eggs has a certain seasonality, in order to ensure that the original quality of fresh eggs and maintain a balanced supply of the market, should do a good job of preserving fresh eggs. Fresh eggs in the preservation of the former, can be used to identify the sensory identification method, light perspective identification method (photo egg method) and specific gravity method to identify its freshness, remove the old eggs, so as not to affect the preservation effect. The following are several methods of preservation of fresh eggs.　　1. Refrigeration method will be tested and qualified fresh eggs, stored in the temperature of 1 ~ 2 ℃, relative humidity 80% ~ 85% of the cold storage, at such temperatures, the embryo stops developing, egg microbial and enzyme activities are inhibited, thereby reducing the changes in the contents of the egg, to achieve the purpose of preservation of freshness.　　Fresh eggs should be pre-cooled for a few days at a low temperature of 3~4℃ before moving them into cold storage. Cold storage of eggs should be clean, no odor, the general preservation time of 4 to 6 months, family life if a small amount of eggs, can be placed in the refrigerator, generally can be saved for 30 to 50 days.　　2. Lime water storage method lime (calcium oxide) after encountering water to generate calcium hydroxide, calcium hydroxide and then combined with the carbon dioxide discharged from the egg, generating insoluble calcium carbonate sunk in the eggshell, the eggshell on the pore blocking, so that the egg respiration is weakened to prevent the eggs from evaporation of water outward and outside the invasion of microorganisms, so as to achieve the purpose of preservation. However, the lime water preserved eggshell will be deposited on a layer of calcium carbonate, eggshell more gray, thin, easy to crack, and eggs slightly lime flavor.　　Practice is to take 0.5 kg of quicklime plus 25 kg of water and mix thoroughly, after 2 days of static precipitation, take the above clear liquid poured into the tank, and then put the selected eggs into the tank to soak, covered with a cylinder lid, the surrounding temperature to maintain below 25 ℃ preferably 10 ~ 15 ℃. After the storage of eggs after the lime water liquid surface to form a glass-like film, which is a normal phenomenon. Using this method can generally save 3 ~ 4 months.　　3. Simple storage method using in the container with filler, such as grain chaff, sawdust, grains, beans, plant ash, etc. for fresh egg storage. This method is mainly to exclude the air in the container, reduce the fresh egg respiration, inhibit the activity of microorganisms and enzymes within the egg, to extend the preservation period of the egg. Specific practice is: put a layer of filler in the container on a layer of eggs, until the container is full.　　4. Coating preservation method Using a variety of coating agents coated on the surface of the eggshell, blocking the eggshell pores, preventing the evaporation of water within the egg and microbial invasion, so that changes within the egg slowly to achieve the purpose of preservation. Specific practice is: 0.1% of borax water disinfection of fresh eggs, dry and put into the coated agent (such as paraffin oil) impregnated with a few seconds kind of fish out, placed in a ceramic pot to dry, at a temperature of 20 ℃ in the environment of the preservation of storage for about 50 days.　　5. light brine storage method 5 kg of fresh water, 35 grams of salt, boiled and stirred, removed and cooled, the egg into the container, and then the matching brine into the brine until the brine is higher than the surface of the egg 3 ~ 4 cm can be. Due to the role of light brine has antiseptic and inhibit the propagation of bacteria, coupled with the isolation of the air with the outside world, so it can maintain the original quality of fresh eggs. Eggs stored in this way to eat with fresh eggs. But in high temperatures, should not be used this method. Fresh goose eggs can also be salted, alkaline, bad, brined and processed into eggs, salted eggs, bad eggs, brined eggs, tiger eggs, etc. for sale, you can get more benefits.
