Food choice model (Shepherd & Sparks, 1994, 1999)
CSIRO Understanding food choices of Asian Consumers
Eurocentric approaches to understanding consumers’ food choice / behaviour
• The science of food choice is mostly described almost exclusively in terms of western (European origin) cultures
• for example, Frewer & van Trijp, 2007; Shepherd & Raats, 2006; Cox & Anderson, 2004; Meisleman & MacFie, 1996; MacFie & Thomson, 1999; Frewer et al, 2001; Marshall, 1995
• Social psychology • “Almost all the theories and data of contemporary psychology
come from western populations (e.g. Europeans, North Americans, Australians, etc)” (Triandis, 1996 p 407)
• Cross-cultural validity• Theories and tools need to be tested in Asian cultures
CSIRO Understanding food choices of Asian Consumers
Scope
• Size: • 50% of the world’s population is Asian
• Dynamics: • Asia is the fastest growing continent in terms of population and
economy (Newman, 1999)• Diversity
• Poorest (Laos) to the richest (Japan)• Published (English) literature focus:
• East & South East Asia• Units of analysis:
• inaccurate and dangerous to make generalisations about geographic, national or cultural “units of analysis” (Douglas & Craig, 1997).
• care should be taken to account for segmentation and/or define homogenous groups of consumers
CSIRO Understanding food choices of Asian Consumers
Globalisation of the food supply
• Increasing choice through greater availability • Global “food systems” (Rozin, 2007)• global products are often the result of producer “push”
for greater efficiency not necessarily based upon consumer demand.
• Much of the interests in food choice and acceptance are based upon a western global food industry wishing to design products for other markets
• However specific cultural values are considered most strong in respect for non-durable consumer goods such as foods (Schutte & Ciarlante, 1998).
CSIRO Understanding food choices of Asian Consumers
Are ‘Western’ consumer science tools and approaches appropriate for Asia?
• Cross-cultural psychology• Cultural issues of bias and equivalence • Recognition of the difference between universal
behaviours and culturally specific behaviours (Triandis, 1994, 1996; Berry 1989).
• Borrowing from linguistics • phonetics meaning universal sounds - etic describes universal
behaviours • phonemics meaning sounds unique to one language - emic
culturally specific. • Triandis (1996) asserts that science seeks to
understand generalizations, • e.g. common elements in food choice (etics)
• however these may manifest as culturally specific emicelements.
CSIRO Understanding food choices of Asian Consumers
Etic and emic (Berry, 1989)
• a classic example of emic is Japanese perception • 5th basic “taste” umami (O’Mahony & Ishii, 1986).• often translated as “savoury”
• Koreans identify an important flavour construct pertaining to noodles as “kusu” (Prescott, 1998)
• a composite flavour also lacking English translation
• Qualitative work (e.g. focus groups) may be necessary to identify which particular issues are salient to a particular culture
• hence avoiding “pseudo-etic” approaches that mistakenly assume universality (Triandis, 1994).
CSIRO Understanding food choices of Asian Consumers
Culture as a major determinant of human food choice
• traditions, beliefs, and values are amongst the main factors influencing preference, mode of food preparation, serving and nutritional status.
• “If one wanted to know about an individual’s food preference, the best question to ask would be, ‘What is your culture or ethnic group?’” (Rozin, 1990)
• A psychological definition of culture:• “shared cognitions, standard operating procedures and
unexamined assumptions”. (Triandis 1994; 1996)• Applied to food behaviour:
• Most Australians do not question the addition of salt to fries (hot chips)
• Do Vietnamese question the high salt content of fish sauce?
CSIRO Understanding food choices of Asian Consumers
Culture’s 7 constructs (Triandis 1994; 1996)
• Tightness • cultural and domain variation in the strength of social norms, rules and regulations. • Japanese culture is thought to be “tighter” (than the USA) generally across mainly domains.
• Cultural complexity • the multiplicity of religious, economic, political, educational, social and aesthetic standards. • Driven by population density
• Active – passive • Obeying elders, • Confucian
• Honour• Respect for elders; • food as gifts
• Collectivism • In many Asian cultures “the self” is defined as an aspect of the collective (e.g. family). • Personal behaviours are subordinated to the collective.
• Individualism • The self is defined as independent and autonomous from collectives. • Personal goals are primary and social behaviour is shaped by attitudes, hedonics and
judgements of utility. • dominates Western behaviour.
• Vertical and Horizontal relationships • Hierarchy contrasts with egalitarian social behaviour. • Many Asian societies are characterised by vertical or hierarchical relationships.
CSIRO Understanding food choices of Asian Consumers
Collectivism and individualism
4 important attributes 1. self
• unit of social space is the individual or group 2. goal structures
• individualists give priority to individual goals 3. behaviour as a function of norms and attitudes
• individualists are driven by attitudes, • collectivists driven more by social norms
4. focus on needs • in-group (collectivists) • social exchange or contractual relationships (individualists).
• + 60 other attributes of collectivist culture (relative to individualists), some relevant to food choice e.g. • lower self esteem; • lower self efficacy; • lower use of affect in decision making; • greater group decision making.
The influence of ‘important others” and motivation to comply
CSIRO Understanding food choices of Asian Consumers
What does Culture mean in terms of food choice?
• Shared food processes and cultural favours (E. Rozin, 2000; 1982),
• exposure and familiarity• Attitudes, social norms
• – extensive application of Theory of Planned Behaviour (Ajzen, 1985) to food behaviours (Armitage & Conner, 2001; Baranowski et al, 1999)
• self esteem (Teixeira et al 2004)• predictor of weight control?
• self efficacy (Bandura’s Social cognitive theory; protection motivation theory),
• predictor of • Intentions to consume
• functional foods• Selenium enriched foods• Omega-3
• Weight control • use of affect in decision making
• Use of heuristics; short cuts• Hedonics – liking - disliking
CSIRO Understanding food choices of Asian Consumers
Beyond collectivism – individualism: Values
• Motivating beliefs or values (Schwartz, 1994, 1992; Hofstede, 1984; Rokeach, 1973)
• Schwartz’s (1992) study of 20 countries (n ~ 200/sample) included:
• PR China (5 samples); • Hong Kong (2); • Japan (3) • Taiwan (1).
• Searching for universality• Most of the Chinese samples (Shanghai teachers, students
and factory workers) deviated from the theoretical universal structure (emic).
• most important reported motivational goals or values:• “societal harmony” (Taoism)• “virtuous interpersonal behaviour” (Confucianism) • “personal and interpersonal harmony” (Buddhism)
• Hong Kong, Japan, Taiwan and Guangzhou (PRC) did fit the universal structure of values (etic)
CSIRO Understanding food choices of Asian Consumers
Philosophy & beliefs
• Underpinning values are Confucian philosophy and a multiplicity of religions
• Religion has a direct influence upon food choice (Fieldhouse, 1995; Cox & Anderson, 2004)
• Confucianism• Stability achieved by the management of interpersonal
relationships (particularly the importance of family) • relationship between individuals and society. • Self-regulation of desires, relationships, politeness, respect,
hierarchy, and social harmony • Resilient, pervasive: China (Chinese communities), Japan,
Korea, Vietnam, etc • Social norms
CSIRO Understanding food choices of Asian Consumers
Use of motivating values
• Origins in marketing and advertising (Reynolds & Olson, 2001)
• Means-end-chain (laddering) studies (Reynolds & Olson, 2001; Leppard, Cox & Russell, 2004)
• Applications to choice of foods, functional food and genetically modified foods
• Addition to Theory of Planned Behaviour (Le Page, Cox, Russell, Leppard, 2005) –
• questions the importance of values in everyday food choice• Does not add much to predictive theory based models • but could be important in terms of novel foods
CSIRO Understanding food choices of Asian Consumers
Do genetics account for differences in food acceptance?
• Genetically moderated differences in physiology may account for individual differences in sensory perception (Drewnowski & Rock,1995)
• 6-n-propylthiouracil (PROP): bitter• Marker for genetic / physiological / perception differences • Taste receptors (fungiform papillae density)• Super-tasters; medium-tasters; non-tasters• Some evidence that “Asians” are more likely to be “super-tasters”
(Parr, 1934; Drewnowski, Kristal & Cohen, 2001)• Malaysians were found to rate PROP more bitter than European-
Australians (Holt, Cobiac, Beaumont-Smith, Easton & Best, 2000) • however unrelated to perceptions of sweetness intensity or liking for sweetness.
• Conflicting US data on whether such sensitivity determines avoidance of, for example, bitter foods (vegetables):
• not in adults (Yackinous & Guinard, 2002) • in children (Bell & Tepper, 2006)
• Over-ridden by • Culinary practices? • paired conditioning (bitter coffee consumed by supertasters)?• PROP as only a marker – not a predictor
CSIRO Understanding food choices of Asian Consumers
Do Asian consumers have unique sensory perception and preference?
• Perceptions • Measured by threshold, sensitivity or discrimination tests.
• Taste• no differences in perceptions of the 4 basic tastes between
“westerners” vs. Koreans, or Japanese, or Malaysians • (Druz and Baldwin,1982; Yamaguchi, Kimura & Ishii ,1988; Laing et
al., 1993; Prescott & Bell, 1993; Holt et al, 2000)• 5th taste: Umami?
• Odour• perceptual similarity of “westerners” and Japanese or
Vietnamese (Ayabe-Kanamura et al, 1998; Distel et al, 1999; Chrea et al, 2004)
• Recognition related to experience• Colour
• Universality in naming colours (Kay & Regier, 2003)• Colours have differing cultural meanings
CSIRO Understanding food choices of Asian Consumers
Preference
• Taste intensity liking varies between cultures depending on the context or food studied,
• no consistency in direction or magnitude across products
• (Druz & Baldwin, 1982; Bertino, Beauchamp & Jen, 1983; Prescott et al., 1997; Prescott et al., 1998; Holt et al., 2000).
• product dependent differences are related to familiarity and exposure
• (Laing et al, 1994; Prescott & Bell, 1995; Prescott, 1998). • Control for familiarity and exposure
• A cross-cultural study of Chinese-origin Australians vs. European-origin Australians (Murray, Easton & Best, 2000)
• novel extruded cereal snack products. • In contrast to culture, age was found to be a factor in
discriminating between preferences for textures.

Sensory preferences
(Adapted from
Mela, 1995)
CSIRO Understanding food choices of Asian Consumers
Perception and preference: conclusion
• Perception: no• Preference: yes• The evidence available to date suggests that
chemosensory abilities appear generally similar across cultures.
• Therefore, as for individual differences (Rozin, 1990), very little of the cross-cultural variation in food preferences appears to be genetically based, seemingly rather to arise from experience, dietary habits, and attitude to food (Rozin, Fisher, Imada, Sarubin & Wrzesniewski, 1999).
• “shared” processes and cultural favours introduces the concept of exposure and familiarity – cultural flavour principles
CSIRO Understanding food choices of Asian Consumers
Exposure: cultural flavour principles (Elizabeth Rozin 2000; 1982)
• “flavour principles” characterise particular cultures food preferences. • Chinese cuisine: soy sauce, rice wine and gingerroot• regional differences
• Basic foodstuffs • types of rice by variety, grain size and shape, glutinous versus non-
glutinous types (Luh in Ang et al, 1999). • Manipulative techniques;
• manipulation, particulation, incorporation, separation or extraction, marinating, fermentation, heat
• Flavour• oils, liquid sauces; aromatics; pungency
• Dynamic; Cultural integrity, changes with time • Malay Malaysians (in contrast to Chinese) consumers more open to
western influences? (Murray et al, 2001; Cox, Clark & Mialon, 2001; Meudic & Cox, 2001)
• Western influences on Japanese cuisine post 1950 (Cweirtka, 1998)
CSIRO Understanding food choices of Asian Consumers
Can we use liking as a predictor of Asian food choice?
• Affect• Hedonics; disliking - liking• Tuorila et al, (in press, Food Quality and Preference)• The best predictor of Europeans
• consumption • Likelihood to buy• Willingness to try

Asian use of hedonic response scales
• Is Asian “politeness” or “positive bias”(Christopher, 1983; Triandis, 1994, Shutte & Ciarlante, 1998) a problem when assessing liking / disliking (hedonics)?
• little empirical evidence that such cultural bias exists • such assertions are often based upon ‘understandings’ of cultural
values • Use of the nine-point labelled category scale (Yeh et al,1998)
• Koreans, Chinese and Thai consumers, regardless of residency (USA or country of origin) versus US consumers,
• systematically used a narrower range• avoided “dislike” categories, • suggesting a possible cultural bias.
• Chinese-Malaysians vs European-Australians (Cox et al, 2001) • between-groups design, • labelled nine-point category scale vs. unstructured-anchored line scale, • both using computerised responses (anonymity), • no systematic cultural bias.• However non-parametric analysis suggested that the unstructured line
scale encouraged greater use of a range of possible responses • line scales may be a preferred option
CSIRO Understanding food choices of Asian Consumers
Asian use of hedonic response scales
• Yao et al, (2003) compared structured, unstructured and labelled hedonic scales across US, Japanese and Koreans consumers.
• The unstructured scale elicited a wider range of scores for US and Japanese respondents
• however Koreans gave very narrow responses regardless of the scale used.
• only partial support for the “politeness” hypothesis • many unanswered questions remain. • a definite need for “culture free” scales, • ranking might be an alternative to scoring (O’Mahony et al,
2004).
CSIRO Understanding food choices of Asian Consumers
Diet - health beliefs (food as medicine) : the old
• Traditional Chinese medicine (Huang & Huang, 1999) • emphasis on prevention and health promotion, • maintenance of health by prioritising the use of diet above
herbal medicines, above pharmaceuticals• Beliefs are resilient (Wheeler & Tan, 1983) • Interrelated taste and energy/properties to “balance” health.
• Yin• negative, cooling, feminine
• Yang• positive, male, heating
• Dominant “taste” of foods • sweet, sour, salt, bitter, pungent
• 5 “energies” or “properties”• hot, warm, neutral, cool and cold
• Is there evidence to support such diet-health relationships?• Is there conflict with western concepts of health behaviours?
CSIRO Understanding food choices of Asian Consumers
and the new: Functional foods
• Origins in Japan • “foods for specified health uses” FoSHU (Arai, 1996;
2002)• regulated
• potential for greater use of functional foods • Japan, • China • Korea• + Other Asian countries• (Tee, Chen & Ong, 2004; Kojima, 1996; Milo Ohr, 2003).
• Japanese market = US$16 billion (and growing) (http://www.functionalfoodsjapan.com/pages/3/).

Motives for food choice: attitudes and beliefs across cultures 1)
• Belgian, French, US and Japanese beliefs (Rozin et al, 1999) about
• diet-health link, • worry about food, • the degree of consumption of food modified to be healthier, • the importance of food as a positive force in life, • the tendency to associate foods with nutritional vs. culinary
contexts, • satisfaction with the healthiness of one’s own diet
• beliefs about the importance of diet for health = same• However for all other items there were substantial
country (and usually gender) differences. • Japanese:
• the most diet-health conscious • least anxious about their diet. • rated culinary associations with food most highly.

The Theory of Planned Behaviour, (TPB, Ajzen 1985) and Theory of Reasoned Action (TRA, Fishbein & Ajzen 1980)
• Lee (1990) modified TRA for a Korean “Confucian”culture
• included emic constructs “face-saving” and “group conformity pressure” as TRA’s “social (subjective) norms”
• regressed attitudes upon those constructs • Lee & Green, (1991) tested cross-culturally (Korea vs.
USA) the conventional design of TPB, using structural equation modeling (LISREL) for “goodness of fit”.
• The model was found to fit the Korean culture • purchase intentions were predicted by
• subjective norm (others influence) for Koreans (β 0.87) • attitudes in the USA (β 0.90). • consistent with cultural differences in values
• models appear to fit one Asian culture • limited evidence
CSIRO Understanding food choices of Asian Consumers
Recent Korean application of TPB (Chen, 2007)
• Attitudes towards organic foods (n = 440), • moderating effects of food related personality traits
• Food Choice questionnaire (Steptoe et al, 1995) • Food Neophobia scale (Pliner & Hobden, 1992); • Food Involvement scale (Marshall & Bell, 2004)
• RESULTS: • TPB variables moderated by Food involvement. • Main effects • Adjusted R2 0.77. • Intention to purchase organic foods predicted by
• Attitude (β 0.58, p <0.01); • Subjective norm (β 0.21, p <0.01); • Perceived behavioural control (β 0.22, p <0.01); • Perceived difficulty (β -0.04, p = 0.04);
• Attitudes predicted by Food Choice questionnaire items (Steptoe et al, 1995)
• mood, convenience (-), natural content, animal welfare, environment; political values, religion

Objectives (Cox, Evans, Lease, Public Health Nutrition, in press)
• To elicit predictors of variation in intentions to consume novel and conventional foods rich in Long chain fatty acids (LCO3FA), EPA and DHA,
• LCO3FA• protective against coronary heart disease (and other chronic
diseases); • enhances cognitive function (?)
• Intakes low in Australia, USA, China etc (Vietnam?)• To understand potential demand for novel sources of
LCO3FA.• “functional foods”• Hypothesis
• Perceived vulnerability to CHD would drive likelihood to consume LCO3FA rich foods

Methods
• Design • Responses from a consumer sample (n = 220) were elicited. • Independent variables included • protection motivation theory, risk/benefit, CHD risk factors and
socio-demographics.
• Stimuli (Food concepts)• Descriptions of model products representing options for
possible (future) consumption were presented • Dependent variables
• scores for “likelihood to consume”.

Multivariate analysis of results
• RM-ANOVA, post hoc Bonferroni tests• Backward elimination multiple regression
• standardised β values• For every 1 unit change in the independent variables, the
dependent variable changes by β values• R2 amount of variance explained

Conjoint & cluster analysis
• A useful tool for assessing which attributes of (novel) products may drive acceptance (van Kleef et al, 2005)
• Extrinsic (non-chemosensory) attributes• Base product• price
• Credence attributes • health claims, • sources of information
• Product concept profiles • Product attributes as drivers of acceptance
• relative importance of attributes, • utility-disutility of “levels” of attributes,• Utility = worth or value• Part-worths

Summary & conclusions
• Food choice measurement is ‘western’ in origin • a paucity of published empirical Asian studies. • differences in physiology and genetics are unlikely to
be major contributors towards differences in perceptions or preferences for foods
• Culture (belief systems, values and experiences) are likely to be central to consumer preferences
• wealth of information on culture• few published studies that link culture and consumer
behaviour• Need to build on diet-health beliefs • Some application of behavioural theories. • Importance of extrinsic attributes
CSIRO Understanding food choices of Asian Consumers
Summary & conclusions
• Food choice is complex and multivariate• At the individual level there is evidence that acceptance
is moderated by attitudes• Drivers of acceptance of “health enhanced” foods • a PERSON perspective using psycho-social predictive
theories - protection motivation theory • And from a FOOD perspective - conjoint analysis• Segments of consumers can be identified using cluster
analysis (attitudes)• Links to sensory• Need for multi-disciplinary approaches
