Waterborne carbon nanotube ink for the preparation of electrodes with applications in electrocatalysis and enzymatic biosensing
(Pergamon-Elsevier Science Ltd, 2018-10)
Conductive inks with optimal properties for amperometric sensor fabrication are key materials for low cost and high performance electrodes printed on flexible substrates. In this work, electrodes made with a carbon nanotube ...
Partial purification of proteolytic enzymes and characterization of trypsin from merluccius hubbsi by-products
(Wolters Kluwer, 2015-12)
Proteolytic enzymes have been detected and partially purified from Merluccius hubbsiviscera. Crude proteinase extract exhibited its maximal activity at pH 7.94, 59.52ºC and33.93 minutes using azocaseín as a substrate. The ...
Amylase-Functionalized mesoporous silica thin films as robust biocatalyst platforms
(American Chemical Society, 2010-02)
A robust biocatalyst was produced by immobilization of R-amylase into mesoporous silica thin films with local order pore structure and 11 nm pore diameter, supported on glass stripes. The activity of this novel catalyst ...
In vitro and in vivo inhibition of Hass avocado polyphenol oxidase enzymatic browning by paeonol, beta-cyclodextrin, and paeonol:beta-cyclodextrin inclusion complex
(Soc Bioscience Bioengineering Japan, 2019-06)
Polyphenol oxidase (PPO) was extracted from Hass avocados and its physicochemical properties were analyzed. The optimum pH and temperature of the enzyme were pH 7.5 and 20°C. This PPO showed a high thermal stability, since ...
Radio-synthesized protein-based nanoparticles for biomedical purposes
(Pergamon-Elsevier Science Ltd, 2014-01)
Protein-crosslinking whether done by enzymatic or chemically induced pathways increases the overall stability of proteins. In the continuous search for alternative routes for protein stabilization we report a novel technique ...
Evidence of structural changes of an enzymatic extract entrapped into alginate beads
(Elsevier Science Sa, 2013-01)
In this work, we analyzed the structural changes of araujiain entrapped into alginate beads. Araujiain is an enzymatic preparation containing three known enzymatic fractions with each fraction individually presenting a ...
Stability of oil: Water emulsions of amaranth proteins: Effect of hydrolysis and pH
(Elsevier, 2010-08)
In this contribution we have determined the effect of limited enzymatic hydrolysis on the emulsifying capacity of amaranth proteins. The action of enzyme (alcalase and trypsin) and the pH of the continuous phase of the ...
Seaweed-based natural ingredients: Stability of phlorotannins during extraction, storage, passage through the gastrointestinal tract and potential incorporation into functional foods
(Elsevier Science, 2020-11)
Adding value to seaweed by extracting their different bioactive compounds and incorporating them into foods represent an interesting and strategic approach to diversify the functional foods offer. However, once harvested, ...
