“…The relative optimum concentrations of several activators (divalent cations) and cofactors, such as FAD and TPP, were investigated with the probe assembled as a pyruvate biosensor. An extended linearity up to 100 mM of citric acid was achieved (Maines et al 2000). Ribeiro et al prepared several selective membranes for citrate electrodes, having distinct mediator solvents and, in some cases, p-tert-octylphenol as an additive.…”

The importance of analyses of different parameters in food products and monitoring of a production process requires quick and reliable analytical methods and devices. For this purpose, biosensors can be a suitable option, whereas most of the current quality control techniques are time consuming, expensive, and unpractical. In this paper, we describe biosensors developed for analysis of different components present in food samples, namely, glucose, fructose, sucrose, lactose, lactic, malic, acetic, ascorbic, citric and amino acids, ethanol, glycerol, and triglyceride. Biosensors showed desirable sensitivity, selectivity, and response time required for various applications. They are often designed to avoid interference from components present in a complex sample to be analyzed.

“…Another requirement is the ability of the sensor to operate over the environmental concentration range of the analyte of interest in order to eliminate steps as sample dilution. Glucose determination up to 2000 mM [9], malic acid up to 40 mM [47] and citric acid up to 100 mM [48] have been reported. These approaches however are not such as yet able to be used directly in natural products, e.g., fruits, since their pH values differ significantly from the enzyme optimum.…”

“…Biosensors for malic acid employed enzymes including malate dehydrogenace (MDH) (Gamella, et al, 2010;Mazzei, Botre, Favero, 2007) and malate:quinone oxidoreductase (MQO) (Molinero-Abad, AlonsoLomillo, Dominguez-Renedo, Acros-Martinez, 2014). The determination of citric acid requires co-immobilization of three enzymes -citrate lyase (CL), oxalacetate decarboxylase and pyruvate oxidase (PO) (Kim, 2006;Maines, Prodromidis, Tzouwara-Karayanni, Karayannis, Ashworth, Vadgama, 2000). Whereas the determination of tartaric acid using a biosensor has not been published yet.…”
