Combining eutectic solvents and food-grade silica to recover and stabilize anth...
de Souza Mesquita, Leonardo M.; Sosa, Filipe H. B.; Contieri, Letícia S.; Marques, Priscilla R.; Viganó, Juliane; Coutinho, João A. P.Concentrated in the skins of red grapes are the anthocyanins, the primary colorants responsible for the fruits' reddish-purple color. These colorants are recognized for their significant antioxidant properties and potent nutraceutical and pharmaceutical ingredients. Nevertheless, their widespread use is compromised by the (i) need for more efficient yet sustainable downstream processes for their recovery and (i...
Unveiling the use of hydrophobic eutectic solutions as task-specific solvents t...
Kholany, Mariam; Schaeffer, Nicolas; Macário, Inês P. E.; Veloso, Telma; Caetano, Tânia; Pereira, Joana L.; Dias, Ana C. R. V.; Coutinho, João A. P.Haloarchaea make up a class of untapped marine microbial resources that constitute a promising source of valuable compounds with unique characteristics. Bacterioruberin is a C50 carotenoid produced by haloarchaea that possesses interesting antioxidant properties and bioactivities relevant to the food and cosmetic industries. As a substitute for the conventional organic solvents used in the extraction of nonpola...
Crustacean waste biorefinery as a sustainable cost-effective business model
Vicente, Filipa A.; Ventura, Sónia P. M.; Passos, Helena; Dias, Ana C. R. V.; Torres-Acosta, Mario A.; Novak, Uroš; Likozar, BlažMarine-derived food wastes mainly include seafood, fish and feed production resources. From the crustaceans traded annually, 6 to 8 million tonnes of valuable shrimp, lobster and/or crab shells waste are produced worldwide. In this systemic work, the researchers with complementary technical expertise, covering the fields of chemical engineering design, chemistry, materials, predictive environmental sciences and...
Integrative platform for the selective recovery of intracellular carotenoids an...
Mussagy, Cassamo U. [UNESP]; Santos-Ebinuma, Valéria C. [UNESP]; Kurnia, Kiki A.; Dias, Ana C. R. V.; Carvalho, Pedro; Coutinho, Joaõ A. P.Made available in DSpace on 2021-06-25T10:18:39Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-07; Natural bioactive compounds have been attracting growing interest from the industries as a greeneralternative to synthetic raw materials/products. Rhodotorula glutinis yeast naturally synthesizes added value compounds such as lipids and carotenoids, commonly used for cosmetic, pharmaceutical, and food a...
Sustainable strategy based on induced precipitation for the purification of phy...
Martins, Margarida; Soares, Bruna P.; Santos, João H. P. M.; Bharmoria, Pankaj; Torres Acosta, Mario A.; Dias, Ana C. R. V.; Coutinho, João A. P.Phycobiliproteins are fluorescent proteins mainly produced by red macroalgae and cyanobacteria. These proteins, essential to the survival of these organisms, find application in many fields of interest, from medical, pharmaceutical, and cosmetic to food and textile industries. The biggest obstacle to their use is the lack of simple environmental and economical sustainable methodologies to obtain these proteins ...
Uncovering the potential of aqueous solutions of deep eutectic solvents on the ...
Bisht, Meena; Martins, Margarida; Dias, Ana C. R. V.; Ventura, Sónia P. M.; Coutinho, João A. P.Marine fish industries discard huge amounts of fish waste every year, which in turn impose problems of environmental pollution and loss of economic value. About 75% of the total weight of fish is discarded in the form of skins, bones, fins, heads, guts, and scales, which contain high levels of collagen type I. Generally, major sources for commercial collagens are the skin and bone of pigs and cows; however, the...
Ionic liquid-mediated recovery of carotenoids from the bactris gasipaes fruit w...
Mesquita, Leonardo M. de Souza; Martins, Margarida; Maricato, Élia; Nunes, Cláudia; Quinteiro, Paula S. G. N.; Dias, Ana C. R. V.; Coutinho, João A. P.In this work, a process for the extraction and purification of carotenoids from the fruit Bactris gasipaes was developed. Ethanolic and aqueous solutions of ionic liquids (ILs) and surfactants were evaluated on the extraction of these pigments. Thus, we developed an optimized sustainable downstream process mediated by the best solvent with further isolation of the carotenoids and the recyclability of the IL use...
Ionic liquid-high performance extractive approach to recover carotenoids from B...
Mesquita, Leonardo M. de Souza; Ventura, Sónia P. M.; Braga, Anna R. C.; Pisani, Luciana P.; Dias, Ana C. R. V.; Rosso, Veridiana V. deNowadays, one of the biggest challenges for society is the development of appropriate technologies to process the waste residue produced worldwide. In the food sector, the generated waste is estimated to be nearly billions of tons annually. Brazil is one of the most representative examples of the economic and industrial potential of underexplored residues and raw materials. The palm heart, scientifically known ...
R-phycoerythrin extraction and purification from fresh Gracilaria sp. using the...
Vicente, Filipa A.; Cardoso, Inês S.; Martins, Margarida; Gonçalves, Cátia V. M.; Dias, Ana C. R. V.; Domingues, Pedro; Coutinho, João A. P.R-phycoerythrin is a high added-value protein found in red macroalgae with several interesting properties. Despite the promising results found when R-phycoerythrin is used as an optically active center in luminescent solar concentrators (LSCs), it still has some problems that can be attributed to the low stability of the R-phycoerythrin in the presence of the specific contaminant proteins found in the crude ext...
Integration of aqueous (micellar) two-phase systems on the proteins separation
Vicente, Filipa A.; Santos, João H. P. M.; Pereira, Inês M. M.; Gonçalves, Cátia V. M.; Dias, Ana C. R. V.; Coutinho, João A. P.; Ventura, Sónia P. M.A two-step approach combining an aqueous two-phase system (ATPS) and an aqueous micellar two-phase system (AMTPS), both based on the thermo-responsive copolymer Pluronic L-35, is here proposed for the purification of proteins and tested on the sequential separation of three model proteins, cytochrome c, ovalbumin and azocasein. Phase diagrams were established for the ATPS, as well as co-existence curves for the...
