Evaluacion de la estabilidad de carotenoides y actividad antioxidante de la flor de mastuerzo (Tropaeolum majus L. en la microencapsulacion por Spray Drying
Carotenoids were extracted from the petals of yellow nasturtium flowers (Tropaeolum majus L. with hexane, chloroform and petroleum ether at 12, 24 and 48 hours; The highest yield was obtained with chloroform at 24 hours, which was purified to be solubilized with olive oil. It was then microencapsulated with maltodextrin and gum arabic. The dispersion was carried to a Mini Spray Dried B 290 at drying temperatures of 130 degC, 150degC and 170 degC; In the microencapsulation the recovery of total carotenoids was evaluated (p<0.05) due to the interaction of the encapsulating agent and the drying temperature, the highest recovery rates were 74.10 and 83.76 At 130 degC and 150 degC respectively, with gum arabic; No difference (p>0.05) was found in antioxidant activity ranging from 393.00 to 470.97 mmol TE/g. shows. With regard to humidity, hygroscopicity, bulk density (g/cm3) and yield difference was evident (p<0.05) In the solubility no difference (p>0.05) is evident, the microcapsule of carotenoids can be used as functional food
