Graphene based T-shaped monopole antenna sensor for food quality evaluation

Area of Science:

• Materials Science
• Food Science
• Sensor Technology

Background:

• Food adulteration is a significant global issue, compromising food safety, quality, and nutritional value.
• Existing detection methods often lack the speed, sensitivity, or practicality for widespread application.
• There is a critical need for novel, efficient techniques to combat food adulteration.

Purpose of the Study:

• To develop and evaluate a novel sensor for detecting adulteration in liquid food products.
• To assess the efficacy of a graphene-based T-shaped monopole antenna for food quality analysis.
• To provide a reliable method for real-time monitoring of liquid food integrity.

Main Methods:

• A graphene-based T-shaped monopole antenna sensor was designed and fabricated.
• The sensor was immersed in liquid food samples for analysis.
• Mustard oil served as the reference sample, with olive oil and rice bran oil used as adulterants.

Main Results:

• The graphene sensor demonstrated the ability to detect adulteration in liquid food samples.
• The sensor was easily immersed in samples and yielded precise analytical results.
• The system effectively differentiated between pure mustard oil and adulterated samples.

Conclusions:

• The graphene-based T-shaped monopole antenna sensor is a viable tool for liquid food quality assessment.
• This sensor technology is suitable for real-time monitoring applications in the food industry.
• The findings support the potential of advanced antenna sensors in ensuring food safety and authenticity.
