|October 1, 1992
Summary
Garlic consumption is influenced by personal beliefs about taste, smell, and health. Social norms and past behavior significantly predict garlic use, indicating a complex interplay of factors.
Area of Science:
- Food Science
- Consumer Behavior
- Social Psychology
Background:
- Understanding consumer attitudes towards food products is crucial for market analysis.
- Garlic consumption involves complex beliefs and social perceptions.
- Previous research has explored food-related behaviors, but specific factors influencing garlic use require further investigation.
Purpose of the Study:
- To evaluate beliefs, attitudes, and norms regarding garlic consumption.
- To measure social annoyance associated with garlic odor compared to other odors.
- To apply the Fishbein-Ajzen model to predict garlic consumption and intention.
Main Methods:
- 100 shoppers in Helsinki were interviewed about garlic.
- A postal questionnaire assessed annoyance from social odors, including garlic.
- The Fishbein-Ajzen model was used to analyze predictors of garlic consumption.
Main Results:
- Key beliefs about garlic: good taste, unpleasant smell, health benefits.
- Users and non-users exhibited different belief patterns.
- Garlic odor was perceived as less annoying than sweat or alcohol.
- The Fishbein-Ajzen model explained 35-36% of consumption variation; 56-62% with past behavior.
- Both attitudes and subjective norms significantly predicted garlic use.
Conclusions:
- Garlic consumption is influenced by a combination of personal attitudes and social norms.
- Food-related behaviors like garlic use are shaped by both individual perceptions and social context.
- The study highlights the multifaceted nature of dietary choices.

The Scientific Method
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...
The Tongue and Taste Buds
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
Gustation
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
Olfactory Receptors: Location and Structure
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
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,...
The Physiology of Taste
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the diffusion of...
