In the present investigation, plate count analysis was used as a complementary
method to investigate the effectiveness of the hyperspectral
imaging technique in the contamination control of pork by two different
approaches. First, hyperspectral images were used to classify the studied
samples into fresh or spoiled pork. The NIR spectra coupled with LDA
showed very good results with over 95% accuracy for spoilage detection
and could be applied to determine the shelf-life of pork. A rapid test to
predict both the number of bacteria and the remaining shelf-life should
have enough sensitivity to be able to detect a bacterial number lower
Industrial relevance: A novel method based on hyper spectral imaging technique has been successfully developed
for determining the total viable count (TVC) and psychrotrophic plate count (PPC) in chilled pork during storage
non-destructively for the meat industry.
