“…That is, color change was less accelerated with increased temperature. Similar results were obtained by Ferreira et al (1999), for color degradation in water soluble annatto solution (23.9 kcal.mol -1 ), and Grizotto et al (2006), for the overall quality of fruit made from papaya (19.89 kcal.mol -1 ). Moura et al (2001) found values for activation energy of 8.0 kcal.mol q10 -1 and of 1.55 for instrumental color of strawberry pulp.…”

“…Ferreira, Neto, de Moura, and Silva (), when evaluating the kinetics of degradation of norbixin extracts, observed the formation of degradation compounds with yellow coloration when submitted to thermal processes during long periods. In this way, degradation compounds may have been formed during the drying process of the films.…”

“…Exposure to light increased the loss of norbixin similar to that has been previously reported (Ferreira et al ., ; Rao et al ., ; Parvin et al ., ). Gallardo‐Cabrera & Rojas‐Barahona () saw no effect of light, but this is probably due to limitations in their experimental setup where the norbixin loss is only measured at one timepoint.…”

“…A few previous publications have investigated the stability of norbixin in aqueous solution. These studies focus on the effect of temperature and light, where both increased temperature and light affect the stability of norbixin in aqueous solutions (Ferreira et al ., ; Petersen et al ., ), in orange juice (Rao et al ., ) and in yoghurt (Parvin et al ., ).…”
