Curcuminoids found in turmeric have attracted attention due to their remarkable biological activity. Nanoencapsulation may improve their technological properties, but extraction and encapsulation procedures could be time-consuming and expensive when carried out separately. This work aimed to combine extraction and nanoencapsulation steps to obtain curcuminoids-polyvinylpyrrolidone (PVP) nanoparticles directly from plant rhizomes. This single-step procedure was evaluated by a Rotatable Central Co...

Abstract Background Curcumin is a yellow-orange, hydrophobic compound extracted from Curcuma longa and widely used by oriental cultures. It displays numerous biological activities and shows antimicrobial activity against both Gram-positive and Gram-negative bacteria, as well as yeasts and molds. However, its low water solubility decreases its bioavailability and hinders its industrial use. Curcumin may be modified by micro/nanoencapsulation or nanonization (transformation in nanometric crystals)...

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...

Nontoxic conserving agents are in demand by the food industry due to consumers concern about synthetic conservatives, especially in minimally processed food. The antimicrobial activity of curcumin, a natural phenolic compound, has been extensively investigated but hydrophobicity is an issue when applying curcumin to foodstuff. The objective of this work was to evaluate curcumin microcrystals as an antimicrobial agent in minimally processed carrots. The antimicrobial activity of curcumin microcry...

In the present work, poly (lactic acid)/thermoplastic starch/gelatin sheets were produced by calendering–extrusion process and silver nanoparticles (AgNPs, synthesized by chemical reduction with d-glucose), were incorporated at sheet surfaces to promote antimicrobial activity. A gelatin solution containing AgNPs was enzymatically crosslinked as a layer at sheets surface using transglutaminase. AgNPs presented 63 nm (z average size) and spherical shape (scanning electron microscopy, SEM) while mo...
