Curcumin Nanoparticles as a Pigment of Polyamide Textiles: Influence of Conditi...
Moraes, Katharina S.; Oliveira, Aline de; Ferreira, Bruna T. M.; Bona, Evandro; Carneiro, Jaqueline; Peron, Ana Paula; Fernandes, Marta; Zille, AndreaThe growing demand for eco-friendly and sustainable solutions in textile dyeing has attracted interest in natural dyes, since the synthetic counterparts may be potentially damaging to the environment and require the use of additives to efficiently bind them to the fibers. Curcumin, a natural dye derived from Curcuma longa L. rhizomes, has attracted attention due to its notable biological activity and vibrant ye...
Enhancement of fish protein hydrolysates for salad dressing through high shear ...
Moreira, Thaysa F. M.; Oliveira, Anielle; Rodrigues, Vanessa de Carvalho; Carvalho, Amarilis Santos; Quichaba, Michely B.; Peron, Ana P.Thermal and mechanical treatments may affect the structure of hydrolyzed proteins, thus influencing the obtaining of peptides with improved bioactivity. In this work, tila- pia muscle was treated by thermal sterilization or homogenization with ultra-turrax (UT) and hydrolyzed with alcalase to obtain FPHs with antioxidant properties in salad dressing. To evaluate the bioactive potential of FPHs, the acetylcholin...
In situ extraction/encapsulation of olive leaves antioxidants in zein for impro...
Carvalho, Amarilis Santos; Oliveira, Anielle; Moreira, Thaysa Fernandes Moya; Costa, Luis Gustavo Médice Arabel; Marcatto, Gabrielle DonatoThis study presents a sustainable and cost-effective method for preserving the bioactivity of phenolic compounds in olive leaves (OLE) during their application. The extraction and nanoencapsulation of OLE were performed in a single-step process using a rotor-stator system with zein as the encapsulating agent. The nanoprecipitation step was carried out using an aqueous sodium caseinate solution, resulting in sph...
Use of bio-waste of Ilex paraguariensis A. St. Hil. (Yerba mate) to obtain an e...
Menezes, Barbara de Sena Nunes; Caleja, Cristina; Calhelha, Ricardo C.; Pinela, José; Dias, Maria Inês; Stojković, Dejan; Soković, MarinaIn this work, a comparison between the extracts of dehydrated yerba mate (Ilex paraguariensis) and bio-waste of yerba mate leaves from the Brazilian industry was made. The incorporation of the functional extract as a preservative/functional ingredient in a pastry product (pancakes) was tested. The individual profile of phenolic compounds was determined by HPLC-DAD-ESI/MS, and the bioactive potential was assesse...
Unconventional and conventional pickering emulsions: perspectives and challenge...
Hazt, Bianca; Parchen, Gabriela Pereira; Amaral, Lilian Fernanda Martin do; Gallina, Patricia Rondon; Martin, Sandra; Gonçalves, Odinei HessPickering emulsions are free from molecular and classical surfactants and are stabilized by solid particles, creating long-term stability against emulsion coalescence. Additionally, these emulsions are both environmen-tally and skin-friendly, creating new and unexplored sensorial perceptions. Although the literature mostly de-scribes conventional emulsions (oil-in-water), there are unconventional emulsions (mul...
Fish protein hydrolysates: bioactive properties, encapsulation and new technolo...
Moreira, Thaysa Fernandes Moya; Gonçalves, Odinei Hess; Leimann, Fernanda Vitória; Ribeiro, Ricardo PereiraFish protein hydrolysates (FPHs) can be obtained from substrates such as fish muscle, skin, and wastes and assign value to these fish by-products. Proteolytic enzymes catalyze the hydrolysis of these fish substrates' peptide bonds resulting in smaller peptides that present several bioactive properties. Hydrolysates' bioactive properties are a function of the fish species used as the substrate, the enzyme select...
Lutein-loaded nanoparticles reverse oxidative stress, apoptosis, and autism spe...
Viana, Cristini Escobar; Bortolotto, Vandreza Cardoso; Araujo, Stifani Machado; Dahleh, Mustafa Munir; Machado, Franciele RomeroAutism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social interaction and repetitive behaviors. In this study, we assessed the effect of lutein-loaded nanoparticles on ASD-like be-haviors induced by prenatal valproic acid (VPA) exposure in female offspring rats and the possible involvement of oxidative stress and apoptosis. Pregnant female Wistar rats received a single ...
Evaluation of berberine nanoparticles as a strategy to modulate acetylcholinest...
Leimann, Fernanda Vitória; Souza, Luma Borges de; Oliveira, Byanca Pereira Moreira de; Rossi, Bruna Franzon; Silva, Patricia Sabino daResearchers have concentrated efforts in the search for natural-based reversible inhibitors for cholinesterase enzymes as they may play a key role in the treatment of degenerative diseases. Diverse plant alkaloids can inhibit the action of acetylcholinesterase and, among them, berberine is a promising bioactive. However, berberine has poor water solubility and low bioavailability, which makes it difficult to us...
Nanoencapsulation of Curcuma longa L. extract for the treatment of experimental...
Luz, Débora dos Anjos Weber; Rampazzo, Ana Paula de Santi; Borges, Stephanie Carvalho; Neves, Camila Quaglio; Santos, Priscila Dayane Freitas dosInflammatory bowel diseases (IBDs) are gastrointestinal chronic inflammatory diseases characterized by chronic and recurrent intestinal ulcerations. Curcuminoids are naturally occurring polyphenolic compounds with remarkable bioactivity; however, their low water affinity and bioavailability usually hinder their application. Encapsulation techniques can be coupled with extraction procedures to yield nanoparticle...
Biopreservatives against foodborne bacteria: combined effect of nisin and nanon...
Quichaba, Michely Bião; Moreira, Thaysa Fernandes Moya; Oliveira, Anielle de; Carvalho, Amarilis Santos; Menezes, Jéssica Lima; Gonçalves, Odinei HessNisin, a bacteriocin widely used in the food industry, and curcumin, the yellow pigment extracted from turmeric (Curcuma longa L.) stand out among the numerous natural preservatives that have antimicrobial activity. The conversion of these compounds into nanoparticles could be interesting as an alternative to improve technological aspects (such as the low water solubility of curcumin) and to evaluate how synerg...
