Application of edible nanolaminate coatings with antimicrobial extract of Flour...
Salas-Méndez, Esperanza de Jesús; Vicente, A. A.; Pinheiro, Ana Cristina; Ballesteros, Lina F.; Silva, Pedro; Rodríguez-García, RaúlEdible coatings have potential to reduce postharvest losses of fruit such as tomato. In this study, the effects of nanolaminate coatings incorporated with extracts of Flourensia cernua, an endemic plant of the arid and semi-arid regions of Mexico, has been investigated. Ethanol extracts of F. cernua (FcE) were prepared and incorporated into polyelectrolyte solutions of alginate and chitosan. The nanolaminates w...
Scale-up and evaluation of hydrothermal pretreatment in isothermal and non-isot...
Aguilar, Daniela L.; Rodríguez-Jasso, Rosa M.; Zanuso, Elisa; Rodríguez, Diana Jasso de; Amaya-Delgado, Lorena; Sanchez, Arturo; Ruiz, Héctor A.The production of tequila in Mexico generates a large amount of agave bagasse per year. However, this biomass can be considered as a potential source for biofuel production. In this study, it is described how the hydrothermal pretreatment was scaled in a bench scale, considering the severity index as a strategy. The best condition was at 180°C in isothermal regime for 20min with 65.87% of cellulose content and ...
Compositional features and bioactive properties of whole fraction from Aloe ver...
López, M.; Romaní, Aloia; Cerqueira, M. A.; Rodríguez-García, Raúl; Rodríguez, Diana Jasso de; Vicente, A. A.Aloe vera processing leaves generates a liquid and bagasse fraction. The resulting bagasse is mostly discarded as waste. Both the bagasse and liquid fraction can have interesting metabolites with biological activities for pharmaceutical and agro-food industries. The main objectives of the present work were: (1) to characterize the gel, liquid fraction and bagasse of A. vera; (2) to obtain extracts from bagasse ...
Characterization and evaluation of antifungal activity in vitro of Aloe vera fr...
Flores-López, M. L.; Cerqueira, M. A.; Romaní, Aloia; Rodríguez, Diana Jasso de; Vicente, A. A.Aloe vera leaves can be separated in a liquid fraction (exudate) and a mucilaginous pulp (gel). Recently, the antifungal activity of their components has been reported. The common technique for gel extraction from A. vera leaves are the traditional manual (in this case the liquid fraction is not separated) and a mechanical methods. Moreover, as a result of its processing the bagasse is obtained. The aim of this...
Empirical modeling as an experimental approach to evaluate simultaneous sacchar...
Ruíz, Héctor A.; Silva, Daniel Pereira da; Ruzene, Denisse S.; Lima, Luís Filipe Torrinha Ferreira; Rodríguez, Diana Jasso de; Vicente, A. A.In simultaneous saccharification and fermentation (SSF) of lignocellulosic materials, a rapid conversion to ethanol of the produced glucose is expected. The principal benefits are to minimize enzyme sugar inhibition, to improve cellulose conversion rates and to reduce cost compared with separated hydrolysis and fermentation, due to the occurring synergy between enzyme-yeast-substrate in one bioreactor.
