As intra-thyroidal iodine stores should be maximised before conception to facilitate the increased thyroid hormone production during pregnancy, women who are planning to become pregnant should ideally consume 150 μg iodine/d (US RDA). As few UK data exist for this population group, a cross-sectional study was carried out at the University of Surrey to assess the iodine intake and status of wome...

Hydrogenation of oils might be considered as the largest reaction in the edible oil industry. The reaction consists of the addition of hydrogen at the double bounds of fatty acids. Although for some reasons this might be considered a desirable reaction but for some others it might create problems in the food and nutrition chain circle due to the formation of saturated and trans fatty acids. Soy...

Iodine is an essential trace element in the human diet. The following work presents the latest information concerned with iodine determination in raw milk, in Iran. Iodine content of milk was determined by Sandell-Kolthoff method where the samples were taken from Holstein dairy cows, in Shahrkord, the central part of Iran. Thirty six samples were taken from transportation tanks in semi industri...

Based on international standard procedures, the degree of unsaturation on biodiesel was evaluated, called iodine value. Two titration techniques were used to determine the iodine value: colorimetric and potentiometric techniques. The uncertainty of measurement was used to evaluate the quality of the results. The potentiometric technique showed better quality in the determination of the iodine v...

OBJECTIVE To assess iodine nutrition and thyroid function in Mexican childbearing age women. METHODS 101 childbearing age women (21.7 ± 3.5 years) randomly selected from the university student population participated in this cross-sectional study. TSH, thyroid hormones, anti-thyroid antibodies, thyroid volume, iodine intake, and urinary iodine concentration (UIC) were assessed. The knowledge ...

Fatty acid methyl esters prepared from canola, palm, soybean, and sunflower oils by homogenous basecatalyzed methanolysis were stored for 12 months at three constant temperatures ( 15, 22, and 40 C) and properties such as oxidative stability, acid value, kinematic viscosity, low temperature operability, and iodine value were periodically measured. Oxidative stability was significantly reduced u...

This paper presents a modified method of iodine determination in biological material using the results of various authors and own knowledge. For our procedure the iodine mass loss was experimentally determined using radionuclide 1 2 5 l . The average value of iodine mass losses 19.8 % indicates that the method is suitable for the determination of microquantities of iodine (10—400 (ig dm") in bi...

the specific geographical situation of iran places the country among the areas which encounter with deficiency of iodine. such deficiency induces some disorders which vary in different ages. because of high risk of some of these disorders, iodine prophylaxis seems to be important. some authors believe that the prevalence rate of goiter and measurement of iodine in students can be the best way f...

Algae are becoming a strategic source of fuels, food, feedstocks, and biologically active compounds. This potential has stimulated the development of innovative analytical methods focused on these microorganisms. Algal lipids are among the most promising potential products for fuels as well as for nutrition. The crucial parameter characterizing the algal lipids is the degree of unsaturation of ...
