Abstract Lutein is a bioactive found in dark leafy vegetables that may be used as a nutraceutical agent in foodstuff and an inhibitor of key enzymes of the human body such as those involved in the cholinergic system. However, its high hydrophobicity leads to low bioavailability and must be overcome if lutein is to be added in foods. The objective of this study was to evaluate the influence of nanoencapsulated lutein in the activity of the acetylcholinesterase enzyme. The in vitro study was carri...

Abstract Curcumin (E100) is a natural colorant that, besides conferring color, has bioactivity, serving as an alternative to some artificial colorants. As a hydrophobic colorant, its modification/compatibilization with the aqueous medium is required to improve stability and enable its application in hydrophilic food matrices. Herein, different formulations of curcumin (curcumin powder: PC, water-dispersible curcumin: DC: and nanoencapsulated curcumin: NC) were evaluated as yogurt colorants. PC s...
Curcumin is the main curcuminoid found in turmeric rhizomes and is a strong candidate to formulate foodstuff with specific properties. Among various bioactive properties of curcumin, its antiinflammatory activity is remarkable; on the other hand, its low water solubility leads to low absorption. Thus, new formulations need to be developed to improve its efficacy, and encapsulation is a promising alternative strategy in this regard. The objective of the present study was to obtain curcumin-loaded...
OBJETIVO: A curcumina e um composto com varias caracteristicas interessantes para uso nas areas farmaceuticas e alimenticias, todavia, sua instabilidade frente a condicoes externas e insolubilidade em agua diminuem sua aplicabilidade. Deste modo, tecnicas vem sendo estudas para melhorar as caracteristicas tecnologicas da curcumina como a nanoencapsulacao, que vem se mostrando uma alterativa promissora para aumentar a sua biodisponibilidade. O objetivo do trabalho foi encapsular a curcumina utili...
