1. Objective
The agri-food industry increasingly needs reliable, low-cost analytical techniques to control the quality of food and food products. This need stems not only from the demands of regulatory bodies, but also from consumers' growing interest in the composition of the products they consume. Foods are now subject to detailed labelling of their major and minor constituents (artificial flavourings, sweeteners, antimicrobial agents, allergens, glucose in sugars and syrups, alcohol in wines, hydrogen peroxide and sulfites as preservatives, antibiotics in milk, glutamate, vitamins...). Analytical techniques are playing an increasingly important role in controlling raw materials, verifying product content and assessing freshness.
Numerous methods have been developed and applied to the analysis of foods, providing information on their physical and chemical characteristics,...

Economic data
The biosensor industry is booming. The market comprises 4 segments: medical, environmental, agri-food and military, with medical applications accounting for the vast majority (90% of sales are of glucose-detecting biosensors).
In the food industry, pathogen detection is the biggest market. In the USA, a recent study

Commercially available biosensors
Despite a large number of publications on biosensors applied to food analysis, only a small number of systems are commercially available. The disadvantages that need to be overcome are the limited lifetime of biological compounds, large-scale production and ease of use.
