Description générale

Valeric acid is a renewable chemical that can be obtained via hydrogenation of levulinic acid in the presence of nickel-based catalyst or from lignocellulosic biomass. It can undergo esterification to form valerate esters, which can find applications as blending agents for gasoline and diesel, used in the production of biofuels.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Protocoles

In this study, SPME was used for the analysis of free fatty acids in Parmesan cheese using a 65 μm Carbowax/divinylbenzene (DVB) SPME fiber. Headspace extraction of the cheese sample was conducted at 65 °C for 15 minutes and analyzed by GC with FID detection. SPME is ideal for analyzing the volatiles associated with solid food samples. The phase chemistry of the Nukol GC column provides excellent peak shape of acidic compounds.
