Valorization of cork stoppers, coffee-grounds and walnut shells in the developm...
Cruz, Rui; Rainer, Bernhard; Wagner, Isabella; Krauter, Victoria; Janalíková, Magda; Vicente, António A.; Vieira, Jorge M.The development of sustainable materials from the valorization of waste is a good alternative to reducing the negative environmental impact of plastic packaging. The objectives of this study were to develop and characterize pectin-based composite films incorporated with cork or cork with either coffee grounds or walnut shells, as well as to test the films’ genotoxicity, antioxidant properties, and biodegradatio...
Chitosan coating functionalized with flaxseed oil and green tea extract as a bi...
Mendes, Cíntia G.; Martins, Joana T.; Lüdtke, Fernanda Luisa; Geraldo, Ana; Pereira, Alfredo; Vicente, A. A.; Vieira, Jorge M.Ecological and safe packaging solutions arise as pivotal points in the development of an integrated system for sustainable meat production. The aim of this study was to assess the effect of a combined chitosan (Ch) + green tea extract (GTE) + essential oil (thyme oil, TO; flaxseed oil, FO; or oregano oil, OO) coating on the safety and quality of vacuum-packaged beef during storage at 4 °C. An optimized bio-base...
Development and characterization of pectin films with Salicornia ramosissima: b...
Pereira, Daniela G. M.; Vieira, Jorge M.; Vicente, António A.; Cruz, RuiPectin films were developed by incorporating a halophyte plant <i>Salicornia ramosissima</i> (dry powder from stem parts) to modify the film’s properties. The films’ physicomechanical properties, Fourier-transform infrared spectroscopy (FTIR), and microstructure, as well as their biodegradation capacity in soil and seawater, were evaluated. The inclusion of <i>S. ramosissima</i> significantly increased the thic...
Effect of chitosan-Aloe vera coating on postharvest quality of blueberry (Vacci...
Vieira, Jorge M.; Flores-López, M. L.; Jasso de Rodríguez, D.; Sousa, Maria C.; Vicente, A. A.; Martins, JoanaThe present study was carried out to evaluate the effect of chitosan-based edible coatings with Aloe vera extract on the postharvest blueberry fruit quality during storage at 5 °C. Firstly, A. vera fractions (pulp and liquid) were extracted from leaves and evaluated in terms of antifungal and antioxidant capacities. The choice of the most adequate chitosan and A. vera fraction concentrations to be incorporated ...
