Acceptance of genetically modified foods: the relation between technology and evaluation

Area of Science:

• Food science
• Consumer psychology
• Biotechnology

Background:

• Consumer acceptance of genetically modified (GM) foods is a complex issue.
• Understanding the factors influencing consumer perception is crucial for market adoption.

Purpose of the Study:

• To investigate the factors influencing consumer acceptance of genetically modified food products.
• To determine how genetic modification and processing interact to affect consumer evaluation and acceptance.

Main Methods:

• Consumer surveys assessing perceptions of food products.
• Analysis of how genetic modification and processing influence perceived healthiness, naturalness, necessity, and tastiness.
• Statistical modeling to understand the mediation effects of evaluation attributes on acceptance.

Main Results:

• Both genetic modification and processing significantly impact food product evaluation and acceptance.
• Technological changes to 'natural' products (non-processed GM or processed non-GM) have a stronger effect than changes to already technologically adapted products.
• Perceived healthiness, naturalness, necessity, and tastiness mediate the relationship between technology application and consumer acceptance.

Conclusions:

• Consumer acceptance of GM foods is influenced by the interplay between genetic modification and processing.
• The 'naturalness' of a food product is a key factor in how consumers perceive and accept technological modifications.
• Evaluation attributes play a critical role in mediating consumer acceptance of GM and processed food products.
