Piezoelectric quartz crystal sensor for sensing taste-causing compounds in food

Recent advances in recognition elements of food and environmental biosensors: A review

“…The rapid analysis of pirimicarb pesticides in vegetables by MIPs was examined by Sun and Fung (2006). Other recent food applications include the determination of quinine and saccharine in bitter drinks (Sun et al, 2008); and vanillin in vanilla sugar (Avila et al, 2007). The advantage of QCM sensors is that they are simple and cost effective.…”

Review: Highlights in recent applications of electronic tongues in food analysis

“…Although mass sensors are frequently used in electronic nose systems, these devices are hardly used in e-tongues [13]. Nevertheless, their high sensitivity, detection principle based on universal weight changes, capability of real-time electronic read-out, small size, robustness, and low unit cost make mass sensors applications to be promising [36].…”

“…Other application of e-tongues in determining taste-causing compounds in beverages is reported by Sun et al [36]. In this paper, piezoelectric quartz crystal (PQC) sensor array based on molecularly imprinted polymer (MIP) coating was developed for determination of quinine and saccharine in bitter drinks.…”

Electronic Tongue and Neural Networks, Biologically Inspired Systems Applied to Classifying Coffee Samples

“…In the bibliography there are diverse papers where these types of instruments have found numerous applications [4]- [6] [8]- [11]. However, it is also possible to use sensors based on other types of transduction, such as, optical or gravimetric sensors [12]- [14].…”
