[et. al] - Influence of lactose on the diffusion of calcium ions at physiological temperature. "Food Chemistry". ISSN 0308-8146. Vol. 163 (2014) p. 284–288 | Serial title, monograph or event: | Food Chemistry | Volume: | 163 | Abstract: | Mutual diffusion coefficients for calcium chloride (0.100 mol dm−3) in aqueous solutions containing lactose at various concentrations (from 0.005 to 0.200 mol dm−3) have been measured at 37 °C (physiological temperature), by using a conductimetric cell coupled to an automatic system to follow the diffusion. This cell uses an open-ended capillary method based on the measurement of the electrical resistance of a solution placed inside the capillaries at recorded times. The analysis of the CaCl2 diffusion coefficient values obtained suggests the presence of some CaCl2/lactose aggregates in the media, which are influenced by the temperature. | URI: | https://hdl.handle.net/10316/27903 | ISSN: | 0308-8146 | DOI: | 10.1016/j.foodchem.2014.04.108 | Rights: | openAccess |
