Iodine Concentration in Iranian Dairy Milk Products and Its Contribution to the Consumer’s Iodine Intake
BACKGROUND:Due to the large proportion of iodine present in milk and dairy products, they have been one of the important sources of nutritional iodine in several countries. Information about variation in milk iodine concentration in Iran is limited. OBJECTIVES:The present study was conducted to determine the iodine concentration in Iranian milk and dairy ...
متن کاملStudies on the Starch-iodine Reaction
The usefulness of the radiomicrometer in the study of reactions involving a marked color change was indicated in a previous paper (1). It was there shown that the starch-iodine reaction could be investigated in this way. The present paper reports further observations on the reaction, which bear upon the problem of the chemical specificity of some starches and upon the nature of starch-iodide. T...
متن کاملPolyvinyl alcohol as a useful indicator on iodometry: volumetric and spectrophotometric studies on iodine-PVA and iodine-starch complexes.
Iodometry is one of the easiest, most rapid and accurate methods for the determination of a relatively small amount of oxidizing agent, such as residual chlorine. Starch has long been used as a useful color indicator in iodometry. However, we found that PVA (polyvinyl alcohol with partially saponificated; e.g., saponification degree of 88%) is a more useful color indicator than starch. For exam...
متن کاملThe complex of amylose and iodine
The organization of polyiodide chains in the amylose-iodine complex was investigated by Raman spectroscopy, by UV/vis, and by second-derivative UV/vis spectroscopies complemented by semiempirical calculations based on a simple structural model. The Raman spectra indicate that the primary substructures of the polyiodide chains are I–3; and I; sub-units. The second derivatives of the UV/vis spect...
