Derivative formation in the chromatographic analysis of food additives.

Comparative Investigation of Food Supplements Containing Ascorbic Acid

A simple, specific, precise and accurate reversed phase liquid chromatographic (RP-LC) method has been developed for the determination of ascorbic acid in different food additives. The chromatographic separation was achieved on a LiChrosorb C18, 250 mm x 4.6 mm, 5 μm column at a detector wavelength of 230 nm and a flow rate of 1.5 ml/min. The mobile phase was composed of acetonitrile and water ...

Determining the amount of Acrylamide in Potato Chips Using Xanthydrol as a Derivative Representative with Gas Chromatography-Mass Spectrometry

Background and Objectives: In the production process of foods rich in carbohydrates and some other foods containing precursors of acrylamide formation, there is the possibility of acrylamide creation, which is a mutagen and carcinogen material. This study aims to introduce and optimize a new method for determining acrylamide in potato chips using xanthydrol as a derivative representative with g...

Evaluation of Mutagenic Potentials of Some Food Additives by Ames Test

Some chemicals used by human such as food additives are mutagenic and mutagenicity effects analysis of them is very important because of considerable consumption by man. One of the most common methods used in the recognition of the chemicals' mutagenicity is Salmonella Typhimurium Reverse Mutation (Ames) test. The purpose of the present study is mutagenicity effects analysis of sodium nitrite, ...

Determination of the Lipophilicity of Some Food Additives by Chromatographic Methods

The Effect of Nano-Additives on the Hydration Resistance of Materials Synthesized From the MgO-CaO System (RESEARCH NOTE)

In this study, the effect of variety of Nano- additives doping on the hydration resistance of the MgO-CaO system was investigated. Samples were prepared from calcined dolomite and magnesite. Nano-additives that contained cations with various valences (trivalent and tetravalent) used as  a dopant. The bulk density, apparent porosity and hydration resitance were studied and evaluated. Also, phase...
