Quality assessment poultry egg using spectroscopy and maximum liklihood(ml) classifier

Authors: Aboonajmi, M, Ta Najafabadi
Description: The objective of this research was to investigate the feasibility of transmission spectroscopy for Quality assessment of poultry egg. For this purpose special egg holder developed then Haugh Unit and storage time were nondestructively measured using transmission spectroscopy. To obtain a considerable variation in freshness, 300 eggs were stored at 2 environment: (5?C, 75R%H) and (24?C,40%RH). The nondestructive spectral measurements from 300 to 1100nm were compared with Haugh unit and storage time. For two group eggs, 30 eggs in each days were tested by spectroscopy and then also Haugh Unit was measured. Finally we developed our proposed algorithm to predict Haugh Unit by spectrum data as well as storage time prediction using our created database. The maximum likelihood method was compared with Partial Least square (PLS) which is already used for quality assessment poultry egg and shown that Maximum likelihood(ML) method is more effective for the experimental results.
