Chitosan nanogels condensed to ferulic acid for the essential oil of Lippia origanoides Kunth encapsulation

Abstract

In order to enable the applicability of the essential oil of Lippia origanoides Kunth, increasing its stability and dispersion in aqueous base, were prepared nanogels of chitosan modified with ferulic acid to be used in their encapsulation. The results obtained by FTIR and C SSNMR revealed the formation of CS-FA link in the different synthesized nanogels, while the studied by DLS showed particles with varied sizes and positive charge. A satisfactory encapsulation capacity of the essential oil was obtained for the nanogels. However, the nanogel synthesized with the highest proportion of ferulic acid in relation to chitosan 0.760 g of ferulic acid (CF1) showed the highest encapsulation efficiency of 20%. The results indicate the CF1 nanogel potential to encapsulate important components of the essential oil of L. origanoides, being able to guarantee the constituents, preservation, moreover facilitate the dispersion and release, expanding its use.

In vitro and in vivo antiparasitic action of essential oils of Lippia spp. in Koi Carp (Cyprinus carpio) fed supplemented diets

“…In L. origanoides oil, p-cymene was the most abundant compound, followed by carvacrol and γterpinene. These results differ from those obtained in other studies (51,4), which found a higher proportion of carvacrol (41.1-49.7%), with p-cymene being the second most abundant compound. Isolated carvacrol from L. origanoides showed antifungal activity against A. fumigatus and A. flavus (10), and p-cymene from the same plant was effective against Trypanosoma cruzi and Leishmania chagasi (28).…”

Synthesis and Encapsulation of bis-eugenol in a Mesoporous Solid Material: Enhancement of the Antioxidant Activity of a Natural Compound from Clove Oil

“…This technology can embed compounds and protect these ingredients against deterioration, volatile losses, or premature interaction with other ingredients [14]. In special, different research groups have investigated the utilization of essential oils or antioxidant agents encapsulation using different materials, such as chitosan nanoparticles [31,32], jelly-alginates complex microparticles [33], casein micelles [34] and β-cyclodextrin [27].…”

Current Applications of Bionanocomposites in Food Processing and Packaging

“…Nanogels have recently attracted scientific and industry attention because, as hydrogels, their well-defined structures can shift their morphology and shape when subjected to external inputs such as temperature, pH, salt, or magnetic fields. The faster swelling/deswelling characteristic feature of nanogels allied with their excellent permeation abilities, high load capacity, controlled release of active compounds, and faculty to enhance the solubilization of numerous hydrophobic substances, are important advantages when applied as nanocarriers [ 27 , 66 , 67 , 68 ].…”
