Taste Buds and Receptors

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Area of Science:

Food Science
Consumer Behavior
Sustainable Agriculture

Background:

Edible insects (EIs) offer a sustainable alternative to conventional meat.
Consumer neophobia and resistance to EIs exist, particularly in Western countries.
Understanding perceptions is crucial for promoting EIs as a food source.

Purpose of the Study:

To investigate consumer perceptions of edible insects.
To validate a scale for measuring these perceptions.
To identify factors influencing acceptance and barriers to consumption.

Main Methods:

Descriptive cross-sectional study with a questionnaire survey.
3711 participants from six diverse countries (Croatia, Lebanon, Lithuania, Mexico, Portugal, Romania).
Factor analysis, cluster analysis, and word analysis of participant responses.

Main Results:

A 24-item perception scale across six factors was validated.
Three participant clusters emerged: Traditionalists, Shoppers, and Innovators, with significant differences.
Commonly associated words were 'disgusting,' 'protein,' and 'nutritive,' indicating ambivalence.

Conclusions:

Edible insect perceptions vary significantly by country and demographics, with global neophobia present.
Consumers recognize the nutritional value, especially protein content, of EIs.
Findings can inform policies to reduce negative perceptions and enhance consumer acceptance for sustainable food systems.
