The egg is a structure that is produced, as a reproductive agent, by the females of certain species of animals (birds, reptiles, fish and insects), which are spherical or oval in shape and usually surrounded by shells. Eggs are generally used for the ectopic growth of these organisms in the early stages of their lives. They are rich in nutrients, an excellent source of high nutritional proteins, vitamins and trace elements. A large egg contains on average 70 calories, 6 grams of protein and 5 grams of fat.
All eggs sold packaged have a code in their shell. The first number of the code is 0, 1, 2 or 3 which means:
0: Organic egg
1: production of free-range chicken
2: chicken production that grew in a chicken coop
3: production of hen grown in a battery cage - cages.
The number is followed by two letters stating the country of origin (eg EL for Greece). The following numbers refer to the production unit, the production chamber and the batch code. Just below this order there may be other numbers indicating their expiration date , which may not exceed 30 days from the date of packing. EU standardization rules require that additional packaging information must be included in each egg pack:
- Class A and / or Fresh Eggs
- Number of eggs in the package
- Egg Weight
- Date of Consumption
- The number of the Ocher Center checked eggs
- Name of the packing center / address / phone
- The advice on keeping in the refrigerator after purchase
Finally, there are four egg sizes:
- S Small eggs up to 53 gr.
- M Medium eggs 53-63 gr.
- L Large Eggs 63-73 gr.
- XL Very large eggs over 73 gr.
