Design and optimization of a shearing grinding device for efficient separation of eggshell and eggshell membrane [PDF]

Frontiers in Bioengineering and Biotechnology
Global poultry egg production reached 100 million tonnes in 2024, and eggshell membranes account for approximately 10% of total egg mass. Mass egg consumption produces enormous amounts of waste eggshell.

Uterine Metabolomic Analysis for the Regulation of Eggshell Calcification in Chickens

Metabolites, 2021
Eggshell quality is economically important for table eggs and functionally indispensable for hatching eggs. During the formation of eggshell in the uterus, organic matrixes in uterine fluid can control and modify the formation of calcified eggshell.

Research Note: L*a*b* color space for prediction of eggshell pigment content in differently colored eggs

Poultry Science, 2022
: Eggshell color is the most intuitive external feature that affects consumer acceptance. Different eggshell colors are mainly determined by protoporphyrin IX and biliverdin content. The selection of eggshell color by the human eye with an eggshell color

Comparison between different breeds of laying hens in terms of eggshell translucency and its distribution in various ends of the eggshell

Poultry Science, 2021
: Eggshell translucency is a ubiquitous external eggshell quality problem caused by variations of eggshell ultrastructure or shell membrane. In previous studies, researchers have widely investigated this phenomenon with nutritional, environmental, and ...
