Obtention and characterization of microcrystalline cellulose from industrial me...
Gómez-García, Ricardo; Sousa, Sérgio C.; Ramos, Óscar L.; Campos, Débora A.; Aguilar, Cristóbal N.; Madureira, Ana R.; Pintado, ManuelaResidual melon by-products were explored for the first time as a bioresource of microcrystalline cellulose (MCC) obtention. Two alkaline extraction methods were employed, the traditional (4.5% NaOH, 2 h, 80 °C) and a thermo-alkaline in the autoclave (2% NaOH, 1 h, 100 °C), obtaining a yield of MCC ranging from 4.76 to 9.15% and 2.32 to 3.29%, respectively. The final MCCs were characterized for their chemical gr...
Unraveling the valorization potential of pineapple waste to obtain value-added ...
Paz-Arteaga, Sarah L.; Cadena-Chamorro, Edith; Goméz-García, Ricardo; Serna-Cock, Liliana; Aguilar, Cristóbal N.; Torres-León, CristianThe pineapple (Ananas comosus) is one of the most commercialized tropical fruits worldwide. Its high processing and consumption generate huge quantities of organic waste and severe economic and environmental issues. Embracing the circular bioeconomy concept, this fruit waste can be applied as a bioresource (raw material) for the obtention of a wide range of high-valued biocompounds by applying innovative and ec...
Solid-state fermentation for phenolic compounds recovery from Mexican oregano (...
Bautista-Hernández, Israel; Gómez-García, Ricardo; Aguilar, Cristóbal N.; Martínez-Ávila, Guillermo C. G.; Torres-León, CristianThe Mexican oregano by-products are a source of bioactive molecules (polyphenols) that could be extracted using solid-state fermentation (SSF). This study fermented the by-products via SSF (120 h) with a lactic acid bacteria (LAB) Leuconostoc mesenteroides. Sequentially, a bioactive and chemical determination was made according to the phenolic content, antioxidant activity (DPPH●/FRAP), bioactive properties (α-...
Successive fermentation of aguamiel and molasses by Aspergillus oryzae and Sacc...
Flores, Orlando; Flores-Gallegos, Adriana Carolina; Muñíz-Márquez, Diana; Contreras-Esquivel, Juan C.; Teixeira, J. A.; Nobre, ClarisseFructooligosaccharides (FOS) are usually synthesized with pure enzymes using highly concentrated sucrose solutions. In this work, low-cost aguamiel and molasses were explored as sucrose alternatives to produce FOS, via whole-cell fermentation, with an Aspergillus oryzae DIA-MF strain. FOS production process was optimized through a central composite experimental design, with two independent variables: initial su...
Impact of simulated in vitro gastrointestinal digestion on bioactive compounds,...
Gómez-García, Ricardo; Vilas-Boas, Ana A.; Machado, Manuela; Campos, Débora A.; Aguilar, Cristóbal N.; Madureira, Ana R.; Pintado, ManuelaThe objectives of this research work were to evaluate the effect of in vitro gastrointestinal digestion (GIT) on melon peel juice (MPJ) powder from fruit processing industry by-products, considering (i) the recovery and accessibility indexes, (ii) the changes on antioxidant activity, and (iii) the prebiotic effect. Throughout exposition to GIT conditions a decrease on the total phenolic content (TPC = 65.31%) a...
A chemical valorisation of melon peels towards functional food ingredients: bio...
Gómez-García, Ricardo; Campos, Débora A.; Oliveira, Ana; Aguilar, Cristóbal N.; Madureira, Ana R.; Pintado, ManuelaThe goal of this work was to characterize the profile of bioactive compounds and the antioxidant activity of inodorus melon peels. Melon peels were divided into three fractions: a solid fraction with a higher content of carbohydrates (84.81%); a liquid fraction with a higher ash content (11.5%); and a pellet fraction with a higher protein content (34.90%). The structural carbohydrates study revealed a compositi...
Biological protein precipitation: a green process for the extraction of cucumis...
Gómez-García, Ricardo; Campos, Débora A.; Aguilar, Cristóbal N.; Madureira, Ana R.; Pintado, ManuelaCucumisin (CUC) from industrial melon by-products was separated for the first time through biological precipitation using carrageenan (CRG). This approach could represent a cost-effective and environmentally friendly process for the industries, avoiding the use of expensive equipment and toxic salts or solvents, such as butanol and ethanol. In this study, biological precipitation of proteins from melon by-produ...
Candelilla wax edible coating with Flourensia cernua bioactives to prolong the ...
Ruiz-Martínez, Judith; Aguirre-Joya, Jorge A.; Rojas, Romeo; Vicente, A. A.; Aguilar-González, Miguel A.; Rodríguez-Herrera, RaúlThe improvement of the postharvest quality of tomato fruits was evaluated using an edible coating functionalized with an Flourensia cernua extract evaluating the antifungal, structural, barrier, and optical properties. The formulation and evaluation of an edible coating and its application on tomato was evaluated using a response surface methodology to determine the ideal concentrations of candelilla wax, whey ...
Process optimization of microwave-assisted extraction of bioactive molecules fr...
Araújo, Rafael G.; Rodriguez-Jasso, Rosa M.; Ruiz, Héctor A.; Govea-Salas, Mayela; Pintado, Manuela E.; Aguilar, Cristóbal N.Avocado seeds are an agroindustrial residue produced largely by avocado processing industries, which is accumulated in high quantities because it has low reuse due to its poor revalorization. The optimization of Microwave-Assisted Extraction (MAE) of bioactive compounds with high antioxidant capacity from avocado seeds were studied in the present work for the first time. Applying two experimental designs, using...
Chapter 5: Biological catalyzers of brown seaweed: biochemical properties, prod...
Cabello-Galindo, Alejandra; Ruiz, Héctor A.; Nobre, Clarisse; Prado-Barragán, Lilia Arely; Rodríguez-Herrera, Raúl; Aguilar, Cristóbal N.Brown seaweeds comprise a unique and rich composition of relevant polysaccharides and bioactive compounds that can reach up to 70% of seaweed tissue, with a wide application in food, nutraceutical, pharmaceutical, cosmetic, and biopolymer industries; but due to the complexity of the seaweed cell wall structure, the extraction methods play a very important role in the recovery of significant amounts of hydrocoll...
