A Disposable Hypoxanthine Sensor Based on a Micro Oxygen Electrode

Analytical Letters, 1989
Abstract A disposable type micro enzyme sensor was constructed using a Clark-type micro oxygen electrode and immobilized xanthine oxidase (EC 1.1.3.22) for the assay of hypoxanthine which is an important marker for the fish freshness estimation. The sensor showed a good response to hypoxanthine and allowed the determination of hypoxanthine in the ...

Yeast alter micro‐oxygenation of wine: oxygen consumption and aldehyde production

Journal of the Science of Food and Agriculture, 2017
AbstractBACKGROUNDMicro‐oxygenation (MOx) is a common winemaking treatment used to improve red wine color development and diminish vegetal aroma, amongst other effects. It is commonly applied to wine immediately after yeast fermentation (phase 1) or later, during aging (phase 2).

Effect of micro‐oxygenation on sensory characteristics and consumer preference of Cabernet Sauvignon wine

Journal of the Science of Food and Agriculture, 2011
Abstract BACKGROUND: The main objective of this study was to improve the structure of a Cabernet Sauvignon red wine in a short period of time by micro‐oxygenation (MOX) at high rates (25 and 50 mL L −1 month −1 ...

Micro‑oxygenation in red wines: Current status and future perspective

Food Chemistry
Micro‑oxygenation (MOX) is the technology providing a slow and continuous oxidation reaction in the whole winemaking process to improve wine quality. However, traditional methods of oxygen management struggle to achieve a precise control over oxygen at critical process points, failing to meet the personalized and diverse production demands of wine.

Efficiency of processing stabilizers using a micro-oxygen uptake technique

Polymer, 1989
Abstract The thermooxidative stability of various low density polyethylene (LDPE) film formulations was investigated using the technique of micro oxygen uptake measurement following multiple extrusions. The results show that the micro oxygen uptake technique is more sensitive than conventional test methods.

Effect of Wine Properties and Operating Mode upon Mass Transfer in Micro-Oxygenation

International Journal of Food Engineering, 2010
All along wine-making and during its ageing, oxygen plays an important role for the evolution of the wine. Solubilization of oxygen into musts or wines occurs when gaseous oxygen is brought into contact with the liquid. In this work, the specific technique of wine micro-oxygenation is addressed through the evaluation of transfer capacity for oxygen ...

Catalase activity measured with a micro oxygen electrode in a pressurized reaction vessel

Analytical Biochemistry, 1977
Abstract The assembly and the use of a simple airtight pressurized reaction vessel are described for the measurement of catalase activity with a micro oxygen electrode in an optically heterogenous medium. The oxygen concentration is expressed as the ratio of observed current to the current in an air-saturated solution.

Enhanced Ammonium Oxidation and Iron Cycle of Feammox Under Micro-Oxygen Condition

Environmental Research
Autotrophic anaerobic ammonium oxidation coupled to Fe(III) reduction (Feammox) is a promising technology for treating low C/N wastewater. However, Feammox still faces bottlenecks of slow ammonium oxidation rate and the continuous supply of Fe(III) source. This study adopts micro-oxygen strategy to overcome these obstacles.

An untargeted metabolomics approach to wine micro-oxygenation

2011
Micro-oxygenation is a common winemaking practice for red wine, that consist in a continuous addition of small amounts of oxygen into the wine in order to improve its color, aroma, texture and conservation time. Object of our project was to study wine micro-oxygenation through LC-MS untargeted metabolomic profiling.

Assessment of macro- and micro-oxygenation parameters during fractional fluid infusion: A pilot study

Journal of Critical Care, 2017
The main goal of this study was to assess whether maximal fluid infusion improves both oxygen delivery (DO2) and micro-circulatory parameters during hemodilution. The secondary objective was to assess the ability of baseline micro-circulatory parameters to predict oxygen consumption (VO2) response following fluid infusion.In a postoperative cardiac ICU,
