Food losses can occur during production, postharvest, and processing stages in
the supply chain. With the onset of worldwide food shortages, interest in reducing
postharvest losses in cassava has been increasing. In this research, the
main goal was to evaluate biochemical changes and identify the metabolites
involved in the deterioration of cassava roots. We found that high levels of
ascorbic acid (AsA), polyphenol oxidase (PPO), dry matter, and proteins are
correlated with overall lower rates of deterioration. On the other hand, soluble
sugars such as glucose and fructose, as well as organic acids, mainly, succinic
acid, seem to be upregulated during storage and may play a role in the deterioration
of cassava roots. Cultivar Branco (BRA) was most resilient to postharvest
physiological deterioration (PPD), while Oriental (ORI) was the most
susceptible. Our findings suggest that PPO, AsA, and proteins may play a distinct
role in PPD delay. |
