Abstract

Abstract : In Japan, fertilised chicken eggs are used to produce influenza vaccines; however, some eggs die and then contaminate the vaccine stock solution, which causes large economic losses and raises health concerns. Therefore, a non-destructive test that allows distinction of normal and unsuitable chicken eggs was developed, first using visible and near-infrared (VNIR) spectroscopy and subsequently a light-emitting diode (LED) light source. Eggs were sampled from an egg farm, and each of the eggs categorised as either normal or unsuitable using candling. Linear discriminant analysis was applied using wavelength absorbance data to distinguish between normal and unsuitable eggs. All of the optical absorbance values of the normal eggs were found to be higher than those of unsuitable eggs. To reduce the production cost, LED lights and photodiodes were used as the light source and light receptors, respectively. A discrimination rate of 92.9% was obtained when LED was used as the light source. Highlights: LED light was used to detect unsuitable chicken eggs in influenza vaccine production. Visible-near-infrared spectroscopy was not used, nor halogen lamps. Differences in absorbance values contributed to the efficient discrimination. Multiple LED setup lowered detection rate due to interference from nearby light sources.
