Abstract
Solid Phase Microextraction (SPME) is an effective, cost-saving, versatile and easily automated solvent-free extraction technique that has become prevalent in the extraction and pre-concentration steps both for analytical procedures for compounds related to aroma and flavors/off-flavors in foods and beverages, as well as in the determination of exogenous contaminants in these samples. Among them, especially relevant is its application to the characterization of beers – the most popular alcoholic beverage in the world, produced after the action of yeasts over malted cereals and seasoned with hops. Therefore, in this chapter we discuss the application of SPME to the assessment of trace constituents in beers and their main ingredients.
