Influence of hydrocolloids (galactomannan and xanthan gum) on the physicochemic...
Andrade, F. J. E. T.; Albuquerque, Priscilla B. S.; Moraes, G. M. D.; Farias, M. D. P.; Teixeira-Sá, D. M. A.; Vicente, A. A.; Carneiro-da-Cunha, M. G.Most gluten-free bakery formulations have starch sources of low nutritional value. The objective of this work was to use fava beans (Phaseolus lunatus) for the production of gluten-free sponge cakes, in addition to evaluating the effects of the partial substitution of fava bean flour by galactomannan and xanthan gum, isolated or mixed at 0.5 and 1.0% proportions, compared with a commercial reference. The proper...
Approaches in biotechnological applications of natural polymers
Albuquerque, Priscilla B. S.; Coelho, Luana C. B. B.; Teixeira, J. A.; Carneiro-da-Cunha, M. G.Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. ...
Quercetin-loaded lecithin/chitosan nanoparticles: physicochemical characterization
Souza, M.; Vaz, A. F. M.; Cerqueira, Miguel Ângelo Parente Ribeiro; Correia, M. T. S.; Vicente, A. A.; Carneiro-da-Cunha, M. G.Quercetin is an abundant flavonoid in food plants and has been extensively investigated for its pharmacological effects that include anti-tumor, anti-inflammatory, antioxidant, and hepatoprotective activities. Being sparingly soluble in water and subject to degradation in aqueous intestinal fluids, the absorption of quercetin is limited upon oral administration. The aim of this study was to encapsulate querceti...
A novel antimicrobial lectin from Eugenia malaccensis that stimulates cutaneous...
Brustein, V. P.; Souza-Araújo, F. V.; Vaz, A. F. M.; Araújo, R. V. S.; Paiva, P. M. G.; Coelho, L. C. B. B.; Carneiro-Leão, A. M. A.; Teixeira, J. A.Objective The present work reports the purification and partial characterization of an antibacterial lectin (EmaL) obtained from Eugenia malaccensis seeds as well as the evaluation of its effect in the daily topical treatment of repairing process of cutaneous wounds in mice. Materials and methods The cutaneous wound was produced by the incision of the skin and use of lectin in the treatment of mice cutaneous wo...
Development of galactomannan membranes from seeds of Cassia grandis for immobil...
Albuquerque, Priscilla B. S.; Arruda, I. R. S.; Soares, P. A. G.; Souza, M.; Costa, R. M. P. B.; Freitas, A. C. C.; Correia, M. T. S.; Teixeira, J. A.Galactomannans are polysaccharides present in the endosperm of numerous plants, particularly the Leguminosae, with several functions, including reserve carbohydrates. Polysaccharides membranes have been used as cross-linked matrix for immobilization of different biomolecules. Lectins are ubiquitous proteins in nature and can be used for a variety of biomedical applications. The aim of this work was the developm...
Immobilization of concanavalin A (Con A) in Xyloglucan film for biotechnologica...
Arruda, I. R. S.; Souza, M. B. S.; Souza, M.; Carneiro-da-Cunha, M. G.; Correia, M. T. S.; Silva, M. V.; Vicente, A. A.Xyloglucan is a polysaccharide extracted from plant seeds, including Hymenaea courbaril var. courbaril, popularly known as jatobá. This carbohydrate has the ability to form matrices for the immobilization of bioactive molecules. Lectins are proteins that, once incorporated in polysaccharide films, can preserve their biological activities. Concanavalin A (Con A) is a lectin that has several biological applicatio...

Physical properties of Policaju based films
Souza, M. P.; Cerqueira, Miguel Ângelo Parente Ribeiro; Souza, B. W. S.; Teixeira, J. A.; Vicente, A. A.; Carneiro-da-Cunha, M. G.The use of edible films in the food protection and preservation has recently increased since they offer several advantages over synthetic materials, such as being biodegradable and environmentally friendly. This work aimed at producing and evaluating the physical proprieties of polysaccharide films from Anacardium occidentale L. tree gum (Policaju) with a view to further application as a coating of fresh fruit....
Production of β-carotene nanoemulsions prepared by a high-speed blender: charac...
Silva, Hélder D.; Cerqueira, Miguel Ângelo Parente Ribeiro; Souza, B. W. S.; Ribeiro, Clara; Avides, Maria do Carmo; Coimbra, Jane S.An efficient implementation of nanotechnology at the industrial level depends on the development of new tools for the application of strategies aimed at improving food quality and human health. Such strategies should offer the potential to significantly improve the solubility and bioavailability of many functional ingredients. The aim of the present work was to prepare -carotene stable nanoemulsions as potentia...
