how to spot fake egg

On a particular Sunday, a woman who gave her name as Ms. Tian was shopping at a vegetable market in Luoyang, in central China’s Henan province, when she noticed a van selling eggs for about 6¢ cheaper than they were going for in supermarkets, the Guangming Daily reported. Assuming that the eggs were from a countryside seller not aware of city prices, she took her chances and bought 2.5 kg of the bargain eggs — which turned out to be fakes. This post from 39Net teaches you how to identify fake chicken eggs from the real ones.

Fake egg’s shell is made of calcium carbonate. Egg yolk and egg white are made of sodium alginate, alum, gelatin, eatable calcium chloride and then add water and food coloring. First pour a set amount of sodium alginate into warm water and mix it into egg white like shape, then mix it with gelatin together with benzoic acid, alum and other chemicals to make the egg white. Egg yolk is just adding lemon yellow food coloring. Together with calcium chloride to form egg mixture into the mold to produce the egg membrane. Egg shell is made of paraffin wax, gypsum powder, calcium carbonate and other materials.


Fake egg is full of chemicals, the main ingredient calcium alginate, at most is a gel. Alum, gelatin etc are only as additives, auxiliary agents. There are national standards on the use of additives; the amount of them is clearly defined. In the artificial eggs they have become the major components; they are not beneficial to the human body. Artificial egg has little or no nutrition value compare with the real egg.

How to identify fake eggs: After opening the egg, egg white and egg yolk will soon mix together.


1. Fake egg’s shell is a little shinier than the real egg, but it is not very noticeable.


2. When touch the fake egg by hand, it feels a little rougher than the real egg.


3. Shake the fake egg will make some noises, because water overflows from the solid agent.


4. Real egg smells a little like raw meat.


5. Tap the egg lightly. Real egg makes a more crisp sound than the fake egg.


6. Shortly after opening the fake egg, egg yolk and egg white will melt together. This is because the egg yolk and egg white are made of the same raw materials.


7. When frying a fake egg, the yolk will spread without being touched.


Toxicological and Side Effect of Artificial Eggs

In the US, UK and other countries additives have an acceptable daily intake value (IDA) which is used as a security value for human intake without health risks. Thus, the side effects must be indicated based on the overcome of ADI values. The marking of egg shell is covered by Commission Regulation 1274/91. This states that ‘Egg shell shall be marked in an indelible color resistant to boiling. The product used must comply with the provisions in force in respect of coloring matters that may be used in foodstuffs intended for human consumption.’ All colors listed in Schedule 1 may be used either to decorate egg shells or to stamp egg shells. Migration of color from the shell to the egg would be negligible and, therefore, even those colors that are listed in Schedule 4, and restricted for certain uses, may be used for this purpose. For example erythrosine, which appears to be the color most commonly used for this purpose, continues to be permitted. Consumers as well as professional food handlers may be follow the safe procedures when handling and preparing eggs and food containing eggs. These procedures are of particular importance in countries (i.e. UK, Europe etc.) where there are cases of egg-borne salmonellosis caused by S. enteritidis. Sometimes calcium carbide is used in formulation of fake eggs. The calcium carbide which is hazardous, when ingested, inhaled skin irritant and even toxic to lungs and mucous membranes. Repeated and prolonged ingestion may damage certain organs. It produces acetylene and calcium hydroxide upon moisture contact. Acetylene a flammable gas that might contain the toxic impurities of hosphine and arsine. Ca(OH)2 – calcium hydroxide is irritating to respiratory system to skin and risk serious damage to eyes. The use of sodium benzoate-it forms carcinogen benzene when used in combination with potassium benzoate and ascorbic acid. Combination with certain food color is known to cause hyperactivity in children .The alum which is used as medicine but excess intake may cause irritation of mucous membrane of GIT, nausea and vomiting . The artificial egg may be dangerous for human because it’s made of different types of chemical compound. SEE: Six Classes Of Food: Functions, Sources and Examples
