Concentrations of Essential Trace and Toxic Elements Associated with Production and Manufacturing Processes in Galician Cheese.

The objective of this study was to determine the trace element composition and the toxic metal residues in Galician cow's milk cheese produced in different systems (artisan, industrial, and organic). Fourteen elements (As, Cd, Co, Cr, Cu, Fe, Hg, I, Mn, Mo, Ni, Pb, Se, and Zn) were determined in 58 representative samples of Galician cheeses by inductively coupled plasma mass spectrometry. The toxic elements were present at low concentrations, similar to those reported for other unpolluted geographical areas.

Characterization of Chickpea ( L.) Flour Films: Effects of pH and Plasticizer Concentration.

The use of flours as a material for biopolymer-based film preparation has gained interest due to the fact that they are a natural mixture of compatible macromolecules and due to their low cost. Chickpea flour shows a promising composition for the development of edible films. The aim of this study was to characterize and evaluate the properties of chickpea flour films as affected by pH (7 or 10) and plasticizer concentration (1% or 3% /) of film-forming solutions.
