The Determination of the Iodine values of Fats and Oils
As early as 1854 Knop proposed the use of potassium bromate and hyclrobromic acid for the determination of Iodine values and lately again Tolle (J. Pharm. Chem, 1905, 31, 111 and 183) and Mossier (Ph^n. Zeit., 1907) have proposed the use of Bromine from one source or another for the determination of the degree of unsaturation of fats.

متن کاملDetermination of Triglycerides in Fats and Oils
The developserit, by collaborative study, of a standardised metbod for the determination of the canponent triglycerides of animal and vegetable oils and fats is described. The procedure involves the separation of the triglycerides into groups containing the same number of carbon atoms, the separation being achieved by direct gas-liquid chranatograiy of solutions of the lipids on packed columns ...
متن کاملIntestinal Absorption of Fats.
Great progress in understanding the mechanisms of fat absorption by the mammalian intestine has been made in the past decade and a half. In contrast to the contentions of rival theorists of the century before this, it has been possible for many laboratories throughout the world to confirm observations made by use of the new tools available, and to come to agreement on current interpretations of...
