Sweden’s Disgusting Food Museum: 80 food items
Why some cultures love the tastes you hate?
Sweden’s Disgusting Food Museum:• Wine made of
baby mice • Fruit Bat Soup • Frog Smoothies• Canned pork
brains with milk gravy
But vegemite toast…
Taste and Food Preference
• ‘Taste’ is a key driver of food choice
• Evolutionary perspective of taste (sweet=energy)
• Large individual variation in capability to perceive taste

Individual variation in perception

Individual
Individual: Genetics, gender, age, health status, dietary intake, emotions, smoking status, pregnancy
Exposure: Habits, familiarity, prior experience
Environment: Culture, family/friends/ context

55% of Asians were Supertasters, compared to 24% of Caucasians were Supertasters.
Supertaster: Experiences the sense of taste with far greater oral sensation including texture

Cross-cultural differences in sensory taste perception
• Intensity perception of the 4 basic tastes between “westerners” (Australians) vs. “Asians” (Japanese) does not differ much (Laing et al., 1993, Prescott, 1998, Holt et al., 2000, Prescott & Bell, 1993)
• Differences in responses to taste stimuli emerge when hedonic responses are measured (Laing, 1993)
Cross-cultural differences in food preference
• Mean liking of sweet products were dependent on the context in which sweetness is judged (Prescott & Bell, 1995).
Exporting to Asia?
Exporting to Asia
• Asia is highly differentiated
• Preference of drinking water temperature differs throughout Asia
Challenges of exporting to China
• ~1.4 billion people in China (4.79 million in NZ)
• China is a highly differentiated nation
Challenges of exporting to China
• Representative group of Asian consumer
• Translation/Mistranslation of Sensory Perception (e.g. Sweetness and “freshness”)
• Scale usage
Conclusions
• Cross-cultural differences in food preferences and perception• China is a highly differentiated nation – cross cultural challenges
needs to be considered
