Nanotechnology in the agri-food sector: Consumer perceptions

Area of Science:

• Food Science
• Consumer Behavior
• Nanotechnology Applications

Background:

• Nanotechnology offers innovative solutions for food processing and packaging.
• Understanding consumer perceptions is crucial for the adoption of these technologies.

Purpose of the Study:

• To assess Spanish consumers' opinions on nanotechnology in food processing and packaging.
• To identify key areas of nanotechnology application in the food industry.
• To evaluate consumer neophobia towards new food technologies.

Main Methods:

• Literature review to identify nanotechnology applications in food.
• Consumer survey to gauge opinions and purchase intentions.
• Assessment of neophobia levels related to food technologies.

Main Results:

• Five key nanotechnology applications were identified: new ingredients, antimicrobial systems, processing methods, sensors, and packaging.
• Products utilizing nanotechnology received positive evaluations, with packaging applications favored over direct food incorporation.
• Consumers exhibited medium neophobia; those with more technological knowledge were less neophobic and more receptive.

Conclusions:

• Nanotechnology has potential in food processing and packaging, particularly in packaging applications.
• Consumer acceptance is influenced by the perceived role of nanotechnology and existing knowledge levels.
• Targeted communication can mitigate neophobia and enhance consumer trust in novel food technologies.
