Area of Science:

  • Food Science
  • Agricultural Engineering
  • Microbiology

Background:

  • Eggshell microcracks compromise food safety by allowing microbial contamination.
  • Detecting microcracks is challenging for human inspectors.
  • Novel technologies are needed to improve egg quality assessment.

Purpose of the Study:

  • To evaluate the impact of a modified pressure imaging system on egg quality during extended cold storage.
  • To determine if microcrack detection technology affects physical quality factors of eggs.

Main Methods:

  • Eggs were subjected to modified pressure imaging for microcrack detection.
  • Eggs were stored at 4°C for 5 weeks with weekly quality assessments.
  • Physical quality factors including Haugh units, albumen height, egg weight, shell strength, and total solids were measured.

Main Results:

  • The modified pressure imaging system demonstrated 99.6% accuracy in detecting cracked and intact eggs.
  • Only the percentage of whole egg total solids showed a significant difference between treated and control eggs (P < 0.05).
  • No significant negative impact on other measured egg quality parameters was observed.

Conclusions:

  • Modified pressure imaging for egg microcrack detection does not compromise egg quality during extended cold storage.
  • This technology can enhance food safety by reducing cracked eggs in the supply chain.
  • The system offers a reliable method for identifying microcracks without affecting product quality.
