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...
Nisin, 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...
This 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...
Brazil nuts are largely consumed either as a whole or as an ingredient in different food products. These seeds are rich in lipids that are susceptible to oxidation, which is the most common cause of deterioration in their sensory and nutritional quality. Active food packagings are a potential strategy to prevent food lipid oxidation. In this work, thermoplastic starch/poly (butylene adipate-co-terephthalate) (T...
In this work, β-carotene was selected to develop a novel study, namely a food colorant system based on beeswax solid lipid particles obtained by hot melt dispersion. The obtained microparticles were characterized by optical microscopy, scanning electron microscopy, particle size analysis and Fourier Transform Infrared spectroscopy. It was observed that the obtained size can be modulated by using different amoun...
A tendência pela utilização de corantes naturais em substituição dos corantes sintéticos vem crescendo dia-a-dia devido aos benefícios que estes apresentam para a saúde. Contudo, é um grande desafio para a indústria obter sistemas baseados em corantes naturais que sejam estáveis, obter produtos com bons rendimentos e isentos de toxidade, quando se visa à sua aplicação em matrizes alimentares. Existem diversas t...
