Filmes de celulose bacteriana com atividade antioxidante
Lima, Helder Levi Silva; Barroso, Maria Karolina de Araújo; Carneiro, Maria José Magalhães; Brígida, Ana Iraidy Santa; Borges, Maria de FátimaNo presente trabalho objetivou-se a obtenção de filmes antioxidantes de celulose bacteriana íntegra (CBI) e CB microfluidizada (CBMF) através da incorporação de peptídeos antioxidantes (PAGPT). Os PAGPT foram obtidos após hidrolise enzimática da gelatina de pele de Tilápia. Para os filmes de CBI, os peptídeos foram adsorvidos pela técnica de banho-finito sob agitação. Para os filmes de CBMF, diferentes misturas...
Filmes antioxidantes comestíveis de celulose bacteriana e hidrolisado de gelati...
Lima, Helder Levi SilvaEdible polymers, natural compounds and nanotechnology are often associated in studies that aim to obtain high performance bioactive films, an innovative technology for food preservation and food quality/safety improvement. Bacterial cellulose (BC), a natural nanostructured polymer, exhibit unique properties and applicability in the food industry. BC can be obtained by bioconvertion of nutrients from agroindustr...
Bacterial cellulose nanofiber-based films incorporating gelatin hydrolysate fro...
Lima, Helder Levi Silva; Gonçalves, Catarina; Cerqueira, Miguel Ângelo; do Nascimento, Elégenes Sampaio; Gama, F. M.; Rosa, Morsyleide F.In this work, films based on bacterial cellulose nanofibers (BCNFs) incorporating gelatin hydrolysate (GH) from tilapia skin were produced. The effect of plasticizer (sorbitol or glycerol) and GH incorporation was evaluated on the physicalchemical and optical properties of films. BCNFs were produced using bacterial cellulose obtained from Hestrin and Schramm (HS) medium (BCNF-HS) or cashew apple juice (BCNF-CM)...
Avaliação do potencial do líquido de sisal e do suco de caju para a produção de...
Lima, Helder Levi SilvaBacterial cellulose (BC) is an interesting biomaterial for researchers because it presents structure in nanoscale dimensions, high crystallinity degree, high porosity, biocompatibility, and high technological potential. Alternative carbon sources have been studied to replace traditional synthetic medium as a substrate for BC production, achieving satisfactory results. The aim of this work was to evaluate BC pro...
