General information
Carl ROTH also offers reagents suitable for food analysis.
On the following pages, you will find the determination of
• Nitrogen according to Kjeldahl
• Sugar
• Mercury
• Trichinae
• Fat
and the determination of the
• Iodine value
• Acid value
• Peroxide value
• Saponification value
as well as other determining factors such as
• Viscosity
• Density
• Hydroxyl value
• Fluoride ions
Iodine Value Determination
The iodine value is a measure of the unsaturated fatty acids in glycerides. The more olefinic double bonds there are in the fat, the higher the iodine value.
Peroxide Value Determination
The peroxide value of a substance denotes how much peroxide it contains. In a mixture of glacial acetic acid and chloroform, the peroxide oxidises the iodide into elementary iodine. The resulting quantity of iodine is then back-titrated using a thiosulphate solution (where a starch solution is used as the indicator). The blank solution tested in parallel is used to calculate the results.
