Journal ArticleDOI
Microencapsulation of betalains obtained from cactus fruit (Opuntia ficus-indica) by spray drying using cactus cladode mucilage and maltodextrin as encapsulating agents
María Carolina Otálora,José G. Carriazo,Laura B. Iturriaga,Mónica A. Nazareno,Coralia Osorio +4 more
TL;DR: These microencapsulates are promising functional additive to be used as natural colorant in the food industry and allowed to obtain more uniform size and spherical particles, with high dietary fiber content.
Journal ArticleDOI
New method to determine antioxidant activity of polyphenols.
TL;DR: The capacity of polyphenolic compounds to reduce the beta-carotene-linoleic acid cooxidation enzymatically induced by soybean lipoxygenase was assayed to determine their comprehensive antioxidant ability, and quercetin and sinapic acid were most active.
Journal ArticleDOI
Supercritical fluid extraction of naringin from the peel of Citrus paradisi.
TL;DR: The highest yield (14.4 g/kg) of naringin, the major flavonoid from the peel of Citrus paradisi L., that could be achieved by supercritical fluid extraction was obtained using supercritical carbon dioxide modified with 15% ethanol and fresh peels at 95 bar and 58.6 degrees C.
Journal ArticleDOI
Variations in bioactive substance contents and crop yields of lettuce (Lactuca sativa L.) cultivated in soils with different fertilization treatments.
TL;DR: Composts and vermicomposts produced through the processing of cattle manures, agro-industrial organic wastes significantly increased lettuce crop yield enriching its pigment contents, although, in some cases, antioxidant value and phenolic levels were reduced.
Journal ArticleDOI
Model studies on the photosensitized isomerization of bixin.
Mariana A. Montenegro,Alessandro de Oliveira Rios,Adriana Zerlotti Mercadante,Mónica A. Nazareno,Claudio D. Borsarelli +4 more
TL;DR: Time-resolved spectroscopic experiments confirmed the formation of the excited triplet state of bixin and its deactivation by ground state bixIn and molecular oxygen quenching processes, and the consequences for food color are discussed.
