Abstract
The present study developed T2 and SPE based
multivariate control charts to evaluate and monitor
the quality changes of tilapia (Oreochromis
mossambicus) (W. K. H. Peters, 1852) Stored in chilled
condition. Principal Component Analysis was performed
to transform the correlated set of response
variables into uncorrelated set of new variables. The
first three principal components together explained
86% of total variability in the data. The same was
used to develop T2 and SPE based multivariate
control charts to monitor the quality profile of
tilapia during storage. The variability of response
variable was within the confidence limits of control
charts during storage. It was found that tilapia had
9 days of shelf life.
