Find Out Which Eggs Failed the Freshness Test at This Supermarket!

Choosing among the multitude of products on the shelves of supermarkets has become increasingly challenging. To help consumers make informed decisions, Il Salvagente conducted a comprehensive test of 22 of fresh eggs. The test aimed to determine the best and worst brands based on various parameters, including hygiene, freshness, pesticide residue presence, and deformities in shape. While all brands performed well overall, some stood out as superior choices. Let's delve into the details of the test results.

Freshness Evaluation of Eggs

One crucial aspect analyzed by Il Salvagente was the freshness of the eggs. To assess freshness, the laboratory employed a simple yet effective test involving a glass of water. By observing the movement of the eggs, the test yielded valuable insights:

  • If the egg remains upright, it is fresh.
  • If the egg tilts slightly, it is starting to age.
  • If the egg floats, it is old and unsuitable for consumption.

During the test, Naturelle Bio eggs, Carrefour bio eggs, Coccodì Bio eggs, and Conad Verso Natura bio eggs exhibited freshness issues. It is important to note that the test was conducted on a specific sample from each brand and purchased from a single point of sale. Therefore, the results may not be applicable to all eggs of the same brand found across the entire Italian territory. Il Salvagente emphasizes that despite the freshness concerns, the edibility of the eggs was never questioned.

Furthermore, the bio brands mentioned above also presented another concern—the presence of a flattened yolk, rather than a high and round one.

Why Do Some Eggs Age Faster?

Il Salvagente sought to understand why certain eggs tend to age more rapidly than others. Experts at the laboratory elucidated the factors contributing to the aging process:

Enzymatic, microbiological, and chemical reactions are responsible for the aging of eggs, as explained by the laboratory. These reactions begin from the moment the eggs are laid, approximately 28 days before the indicated Best Before date on the label. The speed of these reactions varies depending on external factors such as the animal's condition, food storage, ambient temperature, transportation, and handling. Therefore, even eggs laid on the same day may exhibit differences in freshness. If you prioritize freshly harvested eggs, it is advisable to purchase them directly from a trusted farmer, preferably organic sources.
