Are egg classes enough, or do we need an egg quality index?

Abstract

This research on eggs from one of the largest producers on the Serbian market shows variations in the most important internal and external quality characteristics in relation to freshness (expressed in Haugh Units (HUs)) and weight class (S, M, L, XL). In parallel, sensory evaluation was conducted (for the two most common culinary methods of preparation) in order to determine whether consumers notice differences in quality when consuming scrambled eggs and how panellists perceive boiled eggs. Knowing that HUs are a scientific-based quality dimension, as opposed to weight classes that are consumer-based and associated with size of eggs, the authors have introduced a new total quality index elevating the perspective of HUs.
