Probiotics and Human Health

Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.

GC Analysis of Free Fatty Acids in Parmesan Cheese using Nukol™ after SPME using 65 μm Carbowax/DVB Fiber

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.
