Development of galactomannan-based films from Cassia grandis for the immobiliza...
Albuquerque, Priscilla B. S.; Cerqueira, Miguel Ângelo Parente Ribeiro; Coelho, Caroline Correa de Souza; Vicente, A. A.; Teixeira, J. A.Galactomannans are polysaccharides formed by a β(1 4)-D-mannan backbone attached to α(1 6)- D-galactose units. They are commonly extracted from leguminous seeds and used as alternative sources for the production of films. Lactoferrin (Lf), bioactive peptides (BAPs), and phytosterols are biomolecules with functional properties and potential immobilization into films. The use of galactomannan films as immobilizat...
Effect of cellulose microcrystals in starch and chitosan-based films properties
Coelho, Caroline Correa de Souza; Cerqueira, Miguel Ângelo Parente Ribeiro; Albuquerque, Priscilla B. S.; Silva, Otniel Freitas; Vicente, A. A.Cellulose microcrystals (CMC) can be used as reinforcing material in the preparation of composite films. This study aimed to evaluate the effect of CMC in starch and chitosan-based films properties. Starch/CMC and Chitosan/CMC composite films were formulated with 1% (w/v) of biopolymer, 0.25% (w/wbiopolymer) glycerol and 0.1% or 0.2% of CMC. The solutions were prepared at 70◦C during 30 min under stirring and s...
