Determination of Fatty Acid Composition of Food Containing Short Chain Fatty Acids

Enzymatic preparation of structured oils containing short-chain fatty acids.

Structured oils prepared by enzymatic transacylation with triacylglycerols (TAGs) and various fatty acids (FAs) were characterized. Transacylation with trilaurin and saturated FAs (C4:0-C16:0) was performed using Lipozyme RM-IM under standard reaction conditions. The structured oils thus produced had transacylation ratios of 25-37%, as medium-chain FAs > long-chain FAs > short-chain FAs. This r...

Long-chain fatty acid determination

You, J., X. Zhao, Y. Suo, Y. Li, H. Wang, and G. Chen, Determination of LongChain Fatty Acids in Bryophyte Plant Extracts by HPLC with Fluorescence Detection and Identification with MS, J. Chromatogr. B 848:283–291, 2007. A sensitive method has been developed for the determination of long-chain fatty acids (LCFAs) (>C20) using 1-[2-(ptoluenesulfonate)-ethyl]-2-phenylimidazole-[4,5-f]-9,10-phena...

Inhibition of Thermophilic Anaerobic Digestion of Waste Food by Long Chain Fatty Acids and Propionate

Volatile Fatty Acids and Fatty Acid Composition of Silage Species

In this study, total fatty acid composition and volatile fatty acid of silage species in Turkey was determined by using Gas Chromatography (Shimadzu 15-A). Total lipids were extracted from the corn silage, alfalfa silage and figüre silage samples by the method of Folch et al. Silage species were a total of 15 different fatty acids. These fatty acids between C12 to C24 have changed. Unsaturated ...

Simple, rapid method for determination of propionic acid and other short-chain fatty acids in serum.

A semimicro method for measuring propionic and other short-chain fatty acids in serum is presented. The procedure requires as little as 200 microliter of serum. Data are provided for premature infants, children, adults, and patients with propionicacidemia.
