Abstract: | "Betalains extracts were obtained from Fuchsia bougainvillea (Bougainvillea sp.) by using ethanol and distilled water acidified with 1% citric acid. The Betalains present were identified by UV-Vis spectroscopy (~ 537 nm), signal from which the total concentration of betalains was obtained. A stability study was performed on the extracts at different storage temperatures by calculating its concentration over time. The conditions to which the measurements performed were: pH 5.5 (the most stable for this pigments) and temperatures of 4 ° C, 25 ° C and 40 ° C. The temperature has a greater influence on the degradation of betalains, since when stored at high temperatures degrade more rapidly at room temperature degradation slower more however occurs, and 4 ° C samples are stable for at least the time period to which the study was conducted." |
