Advances in Nondestructive Technologies for External Eggshell Quality Evaluation. [PDF]
Sensors (Basel)The structural integrity of poultry eggs is essential for food safety, economic value, and hatchability. External eggshell quality—measured by thickness, strength, cracks, color, and cleanliness—is a key criterion for grading and sorting. Traditional assessment methods, although simple, suffer from subjectivity, low efficiency, and destructive nature ...
