The açaí (Euterpe oleracea) is very perishable, due to its microbial,chemical and enzymatic nature. Furthermore, extensive handlingof the product during the production process also contributes to itsrapid deterioration and contamination. Results showed the açaí asa vehicle for oral transmission of Acute Chagas disease (ACD). Thepasteurization, which is an important thermal processing in the foodindustry, can inactivate the protozoan that transmits the ACD, assuringthe microbiological food safety. However, heat can aff ect importantsensory characteristics such as color and fl avor and decrease açaíacceptance. On the other hand, information about the product caninterfere in consumer choice and intention to purchase. The studywas conducted with two brands of ready-to-eat açaí, pasteurizedand unpasteurized. Aff ective acceptance tests were performed withthe samples, using the hedonic 9-point scale (1 = dislike extremelyto 9 = like extremely). Moreover, evaluations also included frequencyof consumption, and purchase intention. Results demonstrated thatthe pasteurization claim, given to consumers, increased (p<0.05)acceptance of the pasteurized sample (7.5a), initially (without theclaim) (6.2b) not as well accepted as the unpasteurized sample(7.8a) (p<0.05). Despite this, the claim of not pasteurization didnot infl uence the acceptance of the unpasteurized sample (7.8a),which remained well accepted (p>0.05) by consumers (7.8a). Theseresults reinforce the importance of the eff ect of information on theconsumers’ acceptance and purchase intention of açaí.
