does not damage the fruit. The primitive measurements
of impact test do not give substantial information about
the classification of guava maturity. The accuracy of
classification can be improved by performing CA and
LDA on derived indices. The accuracy reaches 77.4%
with the stiffness K as a calibrator from textural analysis
and 84.21% with post-harvest days as a calibrator. How-
ever, a method with an accuracy of classification better
than 75% is good enough for practical application [19].
Hence, this laboratory study encourages the use of fall.
