Abstract

Polypyrrole is one of the conducting polymers that easily synthesized on the different substrates at low temperature. In this work a nanosized POLYPYRROLE (PPy) coated polyester fiber was provided by chemically-deposition of PPy on the surface of polyester. The PPy fiber was employed to the extraction of volatile organic compounds (VOCs) in YOGURT samples as an extraction agent. The effects of QUINCE SEED MUCILAGE (Qm) and storage time on the sensory, PHYSICOCHEMICAL properties, total peak area and the total peak height of volatile compounds of YOGURT in gas CHROMATOGRAPHY (GC) were studied. A factorial design with central points and star points was applied to design the experiments and find out the interaction between different factors and relation between sensory and PHYSICOCHEMICAL properties and GC parameters (total peak area and total peak height) of YOGURT. The results showed that the YOGURT sample acidity is increased by increasing of storage time and YOGURT sample modified by mucilage has more acidity than blank YOGURT, QUINCE SEED MUCILAGE and storage time affect sensory and PHYSICOCHEMICAL properties of YOGURT. There is good relation between sensory properties and GC parameters of YOGURT, so it is possible to determine quality, odor, storage time and other properties of YOGURT samples by gas chromatographic analysis of YOGURT.
