Efeito do congelamento e do tempo de estocagem da polpa de acerola sobre o teor de carotenóides

Abstract: A acerola (Malpighia glabra L.) é uma das principais fontes naturais de vitamina C e, também, excelente fonte de carotenóides. O potencial vitamínico destes pigmentos e sua possível associação com o processo de carcinogênese têm despertado grande interesse na química e estabilidade dos carotenóides em alimentos. O objetivo deste trabalho foi avaliar o efeito do processo industrial de congelamento da polpa de acerola, praticado em pequena empresa do município de Fortaleza-CE, visando à manutenção da estabilidad… Show more

“…The uvaia pulp analyzed presented values above 20 μg g -1 of carotenoids; therefore, it can be indicated as a potential source of this compound. Still comparing uvaia pulp with other fruit pulps, its values for carotenoids are higher in relation to the pulp of acerola (7.1 μg g -1 ) (Agostini-Costa, Abreu, & Rossetti, 2003) and of whole açaí pulp (0.21 to 3.84 mg of β-carotene 100 g -1 ) (Santos et al, 2008).…”

“…Lima et al (2009) studied Buriti from the state of Goiás and found β carotene values of 31220 μg / 100 g and α carotene values of 5352 μg / 100 g, being both higher than those found in DOI 10.1590/0100-29452017 864 Jaboticabal -SP ANTIOXIDANT ACTIVITY AND PHYSICOCHEMICAL CHARACTERISTICS OF BURITI ... this work. Agostini-Costa et al (2003) studied the influence of freezing and storage on the α and β carotene content in acerola pulp and found that over time, there may be a reduction of up to 63% in β carotene content, and there is no loss of α carotene. According to Ângelo and Jorge (2007), the methodology of analysis of any type of food can directly influence the results obtained, since chromatographic apparatuses are more precise and meticulous when compared to analyses performed in conventional way.…”

“…However, changes can occur even at temperatures below 0 °C. The speed at which foods have been frozen and the temperature stability during storage are factors that contribute to their stability (AGOSTINI-COSTA; ABREU; ROSSETTI, 2003;YAMASHITA et al, 2003;SILVA et al, 2010).…”
