Dimethylpolysiloxanes Trans Fatty Acids

Dimethylpolysiloxanes or methyl silicones are commonly added to fats and oils to prevent oxidative foaming in products used in frying Trans fatty acids are a kind of fat that is found in foods. Excessive ingestion of this type of fat is associated with elevated low density
applications. To measure the amount of Dimethylpolysiloxanes, a direct aspiration, flame atomic absorption method is used. lipoprotein (LDL) cholesterol levels, which increases the risk of heart disease. Food entrepreneurs have been taking measures for some
time by independently developing low trans fatty acid foods and selling them on the market. At the same time, nations such as the
Instrument Optics Parameters United States and Denmark are obligated to display the trans fatty acid content on food labels and to adhere to content restrictions
Equipment :Atomic Absorption Spectrophotometer Measurement wavelength (nm) :251.6 on trans fatty acids.
AA-7000F Slit width (nm) :0.7
Lamp current (mA) : 20 BGC mode :BGC-D2
Shown here is a quantitative analysis study conducted for trans fatty acids by the ATR and transmission methods. Measurement was
conducted according to the official method as prescribed by The American Oil Chemists' Society (AOCS). Measurement was also conducted
Results and Repeatability
by the transmission method in cases where the trans fatty acid content was assumed to be very low.
