“…Similar to salt, increasing sugar concentration tends to decrease O 2 solubility in food, with a decrease in magnitude which depends on the nature of the sugar (and more specifically on its carbon number). For example, the addition of 1 mol.kg –1 of ribose caused a decrease in O 2 solubility of 24%, this decrease was of 29% with glucose, 38% with maltose, and 47% with raffinose (Mishima and others , ). Sugar alcohols, such as mannitol or sorbitol, have the same effect as sugars on O 2 solubility (Whitcombe and others ).…”

Oxygen and carbon dioxide solubility and diffusivity are 2 key parameters to understand gas transfer in food matrices. Knowledge of these parameters could help to predict gas concentration in modified atmosphere packaging and, consequently, to predict shelf-life of the product through the development of appropriate mathematical models. The aim of this review is to present the existing methodologies to quantify O 2 and CO 2 contents in food, especially in solid food matrices which is very challenging. There is a focus on how these methodologies could be used to determine gas transfers kinetics. Data of O 2 /CO 2 solubilities and diffusivities in food are collected and compared with a specific emphasis on the food characteristics and factors impacting them. An analysis of the current state of knowledge in solid food matrices is carried out to tentatively build a general predictive model of the O 2 and CO 2 solubility and diffusivity extendable to any kind of food matrix.

“…The reason for this is that the reaction activity of dissolved oxygen and the hydroxide ions increases with alkali concentration goes up and thus the leaching speed is accelerated (Pitzer, 1973). However, when the alkali concentration further increased from 60 wt% to 70 wt%, the extraction of vanadium decreased, this is due to the dramatic decrease in mass transfer efficiency and the oxygen solubility when the alkaline concentration is too high at low temperature (Mishima et al, 1996;Mishima et al, 1997), which is proved by our oxygen transfer efficiency study. Thus, the alkali concentration of 60 wt% was selected.…”

A new metallurgical process via aeration for the decomposition of vanadium slag in concentrated NaOH solutionwas proposed. The improvement of oxygen mass transfer coefficient when using aeration at different NaOH concentration was studied and the effects of critical reaction parameters on vanadium extraction were systematically investigated. The optimal condition was determined to be: alkali concentration of 60%, reaction temperature of 130 °C, alkali-to-ore mass ratio of 6:1, stirring speed of 500 rpm. The yield of vanadium could reach to 97.41% after reacting for 6 h under this reaction condition. The reaction temperature in this new method is 50-270 °C lower than the current liquid oxidation methods reported in the literatures, and the medium alkaline concentration declined from 85% to 60%, exhibiting significant advantages in energy consumption as well as reactor design. Kinetics study indicated that the extraction of vanadium was governed by internal diffusion, and the apparent activation energy was calculated to be 17.57 kJ/mol.
