What objective measurement system, used by Australia's CHOICE magazine, measures egg freshness via egg-white thickness?

Answer

Haugh unit system

The Haugh unit system serves as a quantifiable yardstick for assessing egg freshness and quality based on objective physical characteristics. Specifically, this system measures the thickness of the egg white, or albumen. A higher Haugh unit score indicates a thicker, firmer albumen, which is characteristic of a very fresh egg. Eggs that score 60 Haugh units or higher are generally considered fresh and high-quality. Conversely, an egg scoring below 60 units is classified as weak and watery, indicating diminished freshness. This system provides a scientific metric, as demonstrated when Australia's CHOICE magazine utilized it to test over 300 samples, allowing for a comparison against established international quality benchmarks.
