O papel da clorofila na alimentação humana: uma revisão

Post-harvest conservation of camu–camu fruits (Myrciaria dubia (Kunth) Mc Vaugh) using different temperatures and packages

“…The greatest means were observed in the fruits stored with no package with 43.09 μg 100 g -1 of pulp, followed by the PVC and PET treatments with 40.74 and 40.46 μg 100 g -1 of pulp, respectively, which had their ripening delayed. Published studies ascribe to plant extracts, antimutagenic and anticancer effects of chlorophyll, since these are related often to antioxidant activity, though by an indirect mechanism (Lanfer-Marquez, 2003).…”

“…According to Lanfer-Marquez (2003), there are few scientific works relating the intake of chlorophyll with some effect beneficial to human health, nevertheless, advertisements that chlorophyll would bring benefits over practically all the tissues, organs and systems of the human organisms, especially as the prevention of coronary diseases, certain kinds of cancers diabetes and cataract are concerned, have been conveyed.…”

Constituintes químicos e atividade antioxidante in vivo de flavonoides isolados de Clusia lanceolata (Clusiaceae)

“…As feofitinas são consideradas produtos de degradação das clorofilas, durante o processo de degradação ocorre a substituição do átomo de Mg por dois átomos de H, processo conhecido como feofitinização. 24 Apesar da ocorrência relativamente rara na natureza, a diversidade estrutural das feofitinas e as atividades biológicas que apresentam têm despertado muito interesse.…”

Physical Properties of Edible Gelatin Films Colored with Chlorophyllide

“…Structurally, they are formed by four pyrrolic rings and a fifth isocyclic ring located at the side of the third pyrrolic ring, bonded to each other via methylenic bridges and containing one magnesium atom on their inside. A molecule of propionic acid esterified to a long chain acyclic alcohol, usually a phytol, can be found on the fourth pyrrolic ring, conferring a hydrophobic character to the chlorophyll (Delgado-Vargas and Paredes-López 2002;Francis 2002;Lanfer-Marquez 2003;Humphrey 2004;Chattopadhyay et al 2008). Porphyrin is a stable ring-shaped molecule around which electrons are free to migrate.…”

“…These pigments are obtained from plants and only differ with respect to the position of the functional groups -CH 3 and -CHO, respectively, on carbon 3 (Kidmose et al 2002;Humphrey 2004). These differences in the structure of the chlorophyll are sufficient to produce different Moreover, chlorophyllide is a green pigment obtained by removal of the phytyl group of chlorophyll through hydrolysis in dilute alkali or the action of chlorophyllase, and is thus water soluble (Kidmose et al 2002;Lanfer-Marquez 2003). These chlorophylls are green in color because they absorb strongly in the red and blue regions of the visible spectrum (Kidmose et al 2002).…”
