Solid-Phase Microextraction (SPME) Techniques for Quality Characterization of Food Products: A Review

Abstract

Solid-phase microextraction (SPME) is a relatively new sampling technique wherein sample extraction and pre-concentration could be achieved in a single step. The handling of an SPME device is simple, and the analysis of volatiles could be easy. However, the process becomes complex while analyzing sample matrices of heterogeneous nature. The complexity also increases depending upon the nature of compounds to be extracted. Careful selection and optimization of extraction parameters like fiber coating selection, extraction time, agitation, addition of salt, and extraction temperature have to be undertaken to improve the sensitivity and the reproducibility of this method. This paper reviews the principles associated with SPME technique from a general application viewpoint. Also, a comprehensive review of prior research related to characterization of food quality has been reported. SPME-related solutions for environmental applications have also been analyzed to be applied for new food-related applications.

Food Analysis: Present, Future, and Foodomics

“…Advances in sample preparation aim to minimize laboratory solvent use and hazardous waste production, save employee labor and time, and reduce the cost per sample, while improving the efficiency of the analyte isolation. This includes the development and application of molecularly imprinted polymers in food sample analysis [3], the use of monoliths in sample preparation and analysis of milk [4], the development of porous monolith microextraction techniques for determination of veterinary residues in food matrices by [5], the use of the so-called QuEChERS (quick, easy, cheap, effective, rugged, and safe) methodology for determining pesticide residues in food matrices [6], the application of immunoaffinity column clean-up techniques in food analysis [7], the development of solid-phase microextraction (SPME) techniques for quality characterization of food products [8], the application of ultrasound-assisted extraction to the determination of contaminants in food and soil samples [9], and the use of liquid phase microextraction in food analysis [10]. Besides, some papers have focused on the description of sample preparation strategies used for the analysis of aflatoxins in food and feed [11], antibacterial residues in foodstuffs [12], or the determination of pesticides in foods [13].…”

A Comparative Study of Stout Beer Batch Fermentation Using Free and Microencapsulated Yeasts

“…The analysis also showed that the wort fermentation changes the color profile, depending on whether the yeast is microencapsulated or free. To verify changes in headspace flavors, the GC/MS-SPME was used (Balasubramanian and Panigrahi 2010). This technique allowed a rapid characterization and identification of VOCs in the headspace, indicating possible marker molecules.…”

A novel ultrasonic assistance dispersive solid phase microextraction for preconcentration of Beryllium ion in real samples using CeO2 nanoparticles and its determination by flame atomic absorption spectrometry

“…An important step for determination of an analyte in real samples is sample preparation that affect the selectivity and sensitivity of the analysis method. Nowadays, due to several advantages such as reducing matrix effects and interfering species, and preconcentration of the analyte, microextraction methods are widely used as sample preparation method for real samples such as biological and Pharmaceutical, water and wastewater, industrial and food samples [14][15][16][17]. Dispersive solid phase microexrtraction is a new, rapid and practical method for extraction of various analytes using a dispersing solid sorbent to separate then from the sample solution [18,19].…”
