Automated Determination of Total Fat, Saturated Fat, Monounsaturated Fat and Trans Fat Content in Food Samples
Determination of total fat, saturated fat, monounsaturated fat and trans fat content in food samples is necessary for complying with applicable food labeling requirements. A typical procedure for saponifi cation of the sample involves refl uxing with sodium methoxide in methanol, followed by a second refl ux with boron trifl uoride in order to esterify the free fatty acids. Prior to injection i...

15 صفحه اولPurity Determination and DSC Tzero Technology
The determination of absolute purity by DSC has been an accepted technique since the mid 1960s. One source of error in the purity method, that has limited its applicability and accuracy, is uncorrected thermal lag. New DSC instrumentation incorporates these corrections directly into the heat flow signal. This superior approach leads to improved peak resolution and to more accurate purity analys...
متن کاملDetermination of Meclofenoxate Content in Meclofenoxate Hydrochloride for Injection by DSC and 1H-NMR
Two simple and rapid analytical methods (DSC and 1H-NMR), are proposed for determination of meclofenoxate in meclofenoxate hydrochloride for injection. DSC thermogram is recorded without any sample pretreatment. The response linearity is ensured by linear determination factors R2, which is 0.9982. The recoveries of meclofenoxate hydrochloride in sterile powder for injection are from 98.3% to 10...
متن کاملThree-dimensional comparison of intramuscular fat content between young and old adults
BACKGROUND Fat infiltration within skeletal muscle is known as intramuscular fat (IMF), which increases with aging. Studies have assessed IMF content, using the mid-thigh as a representative location. However, three-dimensional IMF distribution is not well understood. The aim of this study was to compare the IMF content in young and old adults by assessing its distribution along the length of t...
