“…In an additional closely related work, specific enzyme systems were devised to detect analytes comprising markers of the stage of maturity and quality in selected fruits of economic importance to tropical countries, like mangoes or pineapples [56]. Analytes detected were β-D-glucose, total D-glucose, sucrose and ascorbic acid.…”

This chapter presents recent advances concerning work with electronic tongues that employ electrochemical biosensors, that is, bioelectronic tongues. (Bio)electronic tongues represent a new methodological use of (bio)sensors; they start by the use of biosensor arrays and assume the coupling of the obtained complex response with advanced chemometric data treatment; the goal is improving performance of existing sensors. Most of the bioelectronic tongues reported employ enzyme biosensors, essentially based on potentiometric or voltammetric/ amperometric transduction. This report is organized considering the different forms to incorporate biosensors, i.e. considering the number of biosensors in the array, the number of different enzymes used, if the determination is aimed to substrates or inhibitors, etc. Significant applications in real problem-solving, mainly in the food and clinical or environmental fields, are commented.

“…96 Hampl et al, 97 conducted a survey on diet of school children and concluded that children consuming higher fruits and vegetables had higher level of VC and were more healthy. In 2004 Hung et al 98 stated that higher consumption of fruits and vegetables was associated with a comparable decrease in major chronic disease risk and further supported the recommendation of consuming five or more servings of fruits and vegetables daily.…”

“…It is a direct electrocatalytic method and thus with application of Pb(II) ions the stripping potential of ascorbic acid was lowered from 500-600 to 200 mV, although the specifity was not suitable enough in real samples. Direct amperometry has also been used for examination of fruit quality and ripeness [8]. Beside the results, disadvantages mentioned were observed at the applied potential of 350 mV.…”

An amperometric detector and an enzymatic reaction were combined for the measurement of L-ascorbic acid. The enzyme cell (containing immobilized ascorbate oxidase) was connected to a flow injection analyzer (FIA) system with a glassy carbon electrode as an amperometric detector. During optimization and measurements two sample injectors were used, one before and one after the enzyme cell, thus eliminating the background interferences. Subtraction of the signal area given in the presence of enzyme from the one given in the absence of enzyme was applied for measuring analyte concentrations and calibration at 400 mV. Analysis capacity of system is 25 samples/hour. The relative standard deviation (RSD) was below 5% (5 times repeated, 400 μmol/L conc.), linearity up to 400 μmol/L, limit of detection (LOD) 5 μmol/L, fitting of calibration curve in 25-400 μmol/L range was R (2) = 0.99.
