Abstract
Cassava flakes and “garri” are some of the popular cassava products consumed in Africa, Southeast Asia, and Brazil. These products are
cherished for their creamy colour and characteristic aroma. The aroma compounds responsible for the unique aroma notes of these products
were evaluated by means of solid-phase micro-extraction (SPME). Results confirmed that the divinylbenze-carboxen-polydimethylsiloxane
(DVB-CAR-PDMS) fibre was the most appropriate for the isolation of aroma compounds in the cassava products. In addition, the best
response was attained when the extraction temperature was 60°C, equilibrium time 20 min, extraction time 10.94 min, and water addition
35%. Analysis of the odorants led to the identification of 21 compounds with an array of odour notes. However, results of the aroma extract
dilution analysis (AEDA), and odour activity values (OAVs) showed that guaiacol, 3-methylbutanal, methylpropanal, and butyric acids
contributed intensely to the characteristic aroma of both cassava flakes and garri
