“…Garjonyte and Malinauskas [16] immobilized GOx using an electropolymer coating. Despite the primary focus of this research on the blood glucose market, the large amount of knowledge gained in the area has led to the development of several glucose sensors for food [17][18][19]. Boujtita et al [20] concentrated on making biosensors applicable to industrial needs.…”

Production processes require quality control. The quality of food going to the consumer must always be assured. Traditionally this was performed by taking a sample and sending it to a remote laboratory. While this is successful for most samples, this was not always the case. Having remote laboratories means that there could be a significant lag-time between sampling and results. Some unstable samples may have changed or the source material could have been already used/processed by the time they are analyzed. Sensor-based systems, especially those incorporated within flow injection analyzers, can overcome this problem. As the systems can be small and inexpensive relative to other automated analyzers, they can easily be fitted onsite. With the sensors fitted within the production process, a nearly instant reading can be achieved. The advantages and disadvantages of physical, chemical, and biosensors and their applicability to food analysis are discussed. Particular attention is focused on the improvements made to the underlying technology used in biosensor construction.

Glucose Oxidase (GOD) oxidizes glucose to -gluconolactone in presence of moleculer oxygen by forming hydrogen peroxide. As a result of the catalysed reaction, GOD is widely used in cases where glucose or molecular oxygen should be removed to extend the shelf life of foods or used in the production of controlled hydrogen peroxide or gluconic acid. One of the most important application areas of GOD is the construction of the glucose biosensors. There are several studies about GOD purification, immobilization, industrial and analytical applications, so, fast and sensitive determination of GOD activity is essential for these studies. In this study, GOD activity determination methods were reviewed mainly four approaches: determination of decrease in glucose or oxygen concentration and determination of increase in hydrogen peroxide or gluconic acid levels.
