Oxalate biosensor: a review
Oxalate biosensors (OBs) are based on either measurement of oxygen or electrons generated from splitting of H 2 O 2 or heat released during oxidation of oxalate by immobilized oxalate oxidase. OBs are grouped in four classes based on probe used (DO meter, electrochemical, SIRE technology and thermochip). OBs work optimally at: time, 5 s to 15 min; pH, 2.8 8.0; temp., 30 38°C and linearity, 1.0 ...
متن کاملDNA-based biosensor for the electrocatalytic determination of antioxidant capacity in beverages.
Reactive oxygen species (ROS) are produced as a consequence of normal aerobic metabolism and are able to induce DNA oxidative damage. At the cellular level, the evaluation of the protective effect of antioxidants can be achieved by examining the integrity of the DNA nucleobases using electrochemical techniques. Herein, the use of an adenine-rich oligonucleotide (dA(21)) adsorbed on carbon paste...
متن کاملAscorbate Oxidase-Based Amperometric Biosensor for l-Ascorbic Acid Determination in Beverages.
A novel biosensor for l-ascorbic acid determination in different beverages was elaborated. The ascorbate oxidase enzyme (AAO) from Cucurbita sp., EC 1.10.3.3, was immobilized on a screen-printed carbon electrode with poly(ethylene glycol) (400) diglycidyl ether (PEGDGE) as a crosslinking agent. The standards and samples were measured first with a blank electrode. An inert protein, bovine serum ...
متن کاملReview: Diversity of Microorganisms in Global Fermented Foods and Beverages
Culturalable and non-culturable microorganisms naturally ferment majority of global fermented foods and beverages. Traditional food fermentation represents an extremely valuable cultural heritage in most regions, and harbors a huge genetic potential of valuable but hitherto undiscovered strains. Holistic approaches for identification and complete profiling of both culturalable and non-culturabl...
متن کاملMembrane processing of fruit juices and beverages: a review.
Membrane technology for the processing of fruit juices and beverages has been applied mainly for clarification using ultrafiltration and microfiltration, and for concentration using reverse osmosis. The effects of product preparation, membrane selection, and operating parameters are important factors influencing filtration rate and product quality. Technological advances related to the developm...
