Visible spectral imaging (443–726 nm) for evaluating ultraviolet decontamination and predicting bacterial spoilage of vacuum packed chicken breasts

Visible spectral imaging (443–726 nm) for evaluating ultraviolet decontamination and predicting bacterial spoilage of vacuum packed chicken breasts

This work used portable spectral imaging to assess effects of ultraviolet (UV) (254 nm) decontamination and predict bacterial spoilage of vacuum packaged chicken breasts. Samples were scanned using spectral imaging, sampled for colour (L* - lightness, a* - redness, b* - yellowness), pH, total viable...

Zusammenfassung:This work used portable spectral imaging to assess effects of ultraviolet (UV) (254 nm) decontamination and predict bacterial spoilage of vacuum packaged chicken breasts. Samples were scanned using spectral imaging, sampled for colour (L* - lightness, a* - redness, b* - yellowness), pH, total viable (TVC) and total Enterobacteriaceae counts (TEC) over 12 days of storage at 4 °C. UV treated samples had mean a* values 0.42 units significantly higher than untreated controls (p
