The potential of the visible infrared (Vis–IR) (400–1100 nm) transmittance method to assess the internal quality (freshness) of intact chicken egg during storage at a temperature of 30 ± 7 C and 25 ± 4% relative humidity was investigated. Two hundred chicken egg samples were used for measuring freshness and spectra collection during egg storage (up to 25 days). Two correlation models, fi…
