Cassava is widely cultivated in tropical and subtropical regions for its starchy
tuberous root, a great source of carbohydrates. It has a variety of applications,
like animal feeding, culinary or alcoholic beverages. As it is a tropical root,
it undergoes Postharvest Physiological Deterioration (PPD), which is characterized by streaks of blue/black in the root
vascular tissue, which with time spread and cause a brown discoloration. PPD
begins quickly within 24h postharvest and, because of that, the roots need to be
rapidly consumed. Some studies revealed that the deterioration is caused mostly
from wound-healing responses
1. This study was conducted to identify changes
and discriminate cassava samples (IR data) from different regions during PPD with the aid
of supervised and unsupervised methods of data analysis.
