Packaging is today indispensible vehicle to maintain the quality of foods during storage, transport and handling. It is essential need of today’s food industry to protect food products from outside influences and damage, to hold the food products together and provide consumers with ingredient and nutritional profile. In addition, it helps minimizing the use of chemical additives and reducing the impact of packaging waste on the environment (Marsh and Bugusu, 2007). Now days, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology (Kerry et al 2006). It is well known that, new food packaging technologies developed during …show more content…

Major components of biosensor
a) Biologically Active Material: a biological derived material is the one that interact with the food under study .e.g. Antibodies enzymes, microorganisms etc.
b) Detector Element: the detector element which is also called as transducer which transform biological signal into another signal that can more easily measure. I.e. amplified signal e.g. optical transducer, electrochemical transducer, calorimetric transducer etc.
c) Signal Processor: It is used to display the result in user friendly manner.

Most of the enzymes used in biosensor are Oxidizes but there are certain limitations as their activity is susceptible to pH, temperature, ionic strength etc. The enzyme sensor array’s application area was tested from meat to fish products, dairy products, fermented foods and then compared with the conventional LC (Liquid Chromatography) (Lange and Wittman 2002). In food analysis, for the simultaneous determination of the three biogenic amines putrescine, histamine and tyramine is prevalent. The enzyme sensor’s lower detection limits were 5 mg/kg for putrescine and 10 mg/kg for histamine and tyramine with a linear range up to 100 mg/kg for putrescine and 200 mg/kg for histamine and tyramine (Otles and Yalcin, 2012). Thus, biogenic amines are an indicator of food deterioration and only an indirect indicator of food freshness in meat (Rokka et al., 2004) and for monitoring fish spoilage, Pacquit et al. (2007) developed a colorimetric dye-based sensor that detects the presence of total volatile basic nitrogen (TVB-N), a product of
