European Journal of Lipid Science and Technology, 2018 A rapid method is developed to facilitate the Fourier transform infrared (FTIR) spectroscopy analysis of edible oils using disposable polyethylene (PE) films as sample support for the determination of the iodine value (IV) and saponification number (SN). For direct IV analysis, quantification is achieved using the cis and trans double band region (3206–

Biodiesel is an alternative fuel consisting of alkyl esters of fatty acids from vegetable oils or animal fats. The properties of biodiesel depend on the type of vegetable oil used for the transesterification process. The objective of the present work is to theoretically predict the iodine value and the saponification value of different biodiesels from ...

In this study, the friction of eight kinds of poly(vinyl alcohol) hydrogel (PVA-H) samples has been studied under various load and velocity conditions to elucidate the effects of PVA factors such as the degree of polymerization (DP) and the saponification value (SV) on the tribological behavior of PVA-H.

Errors in the acid and saponification values of fatty acids
Journal of the American Oil Chemists' Society, 1962 AbstractAttention is directed to the variation in ester value of fatty acids depending upon method of isolation. The formation of sterol esters increases the ester value of fatty acids. The increase of ester value with elapsed time is discussed. The effect of ester value variation on the results obtained in soap analysis is described, and a possible ...

Quick and reagent-free monitoring of edible oil saponification values using a handheld Raman device
Food ChemistrySaponification value, the average molecular weight of fatty acids, is a crucial parameter for detecting adulteration of edible oils. Conventionally, it is determined in a laboratory setup through a time-consuming, laborious titration process using chemical reagents.
