Resumo

O objetivo deste trabalho foi analisar o teor de compostos bioativos extraídos da cenoura, através de delineamento experimental de 3 fatores, 3 níveis e dois pontos axiais, incluindo tempo de extração (17- 37- 57 min), temperatura (30-50-70ºC) e concentração de etanol (50-65-80%). O resultado foi expresso em porcentagem. Com base nos resultados, pode-se dizer que o tempo não influenciou significativamente a extração dos compostos antioxidantes (p> 0,001), e que a temperatura é diretamente proporcional ao rendimento. Em relação aos compostos fenólicos apenas a temperatura foi significativa, e para os flavonóis, apenas o tempo e a proporção. O uso de etanol como solvente apresentou bons resultados quando comparado aos solventes comumente utilizados, além de ter a qualidade de ser economicamente viável e de grau alimentício. Outro fator importante foi o pré-tratamento da amostra, que permitiu bons valores de rendimento quando comparado à literatura.
