Characterisation of Beef Palatability for Korean and Australian Consumers John Thompson, Rod Polkinghorne, Alan Gee Jong-Moon Lee, InHo Hwang and Kyungnam Kim John Thompson, Rod Polkinghorne, Alan Gee Jong-Moon Lee, InHo Hwang and Kyungnam Kim

Background  MSA is a carcass grading scheme which uses a predictive model to describe the palatability of beef  The MSA scheme is underpinned by consumer taste panel results  There is limited information on the influence of demographic factors on consumer scores for beef –Demographic effects on Sydney consumers –City Vs Country consumers –Japanese Vs Australian consumers  MSA is a carcass grading scheme which uses a predictive model to describe the palatability of beef  The MSA scheme is underpinned by consumer taste panel results  There is limited information on the influence of demographic factors on consumer scores for beef –Demographic effects on Sydney consumers –City Vs Country consumers –Japanese Vs Australian consumers

Background  Previous studies suggest that Korean consumers place more emphasis on taste and less on tenderness than consumers in western societies.  The question: Whether Australian and Korean consumers have the same goal posts in terms of meat quality, given the large geographical and cultural differences?  Previous studies suggest that Korean consumers place more emphasis on taste and less on tenderness than consumers in western societies.  The question: Whether Australian and Korean consumers have the same goal posts in terms of meat quality, given the large geographical and cultural differences?

Project Outline  Co-operative Project between Korea and Australia  Korean –National Livestock Research Institute, RDA staff at Suwon  Australian –Meat and Livestock Australia, Meat Standards Australia and Beef CRC  Co-operative Project between Korea and Australia  Korean –National Livestock Research Institute, RDA staff at Suwon  Australian –Meat and Livestock Australia, Meat Standards Australia and Beef CRC

Aims Overall objective  To examine sensory characteristics of Korean and Australian consumers. More specifically  To determine if Korean and Australian consumers differ in the way they score palatability of beef  The importance of demographic and design effects (cooking, treatment, muscle etc) effects on sensory responses from Korean and Australian consumers Overall objective  To examine sensory characteristics of Korean and Australian consumers. More specifically  To determine if Korean and Australian consumers differ in the way they score palatability of beef  The importance of demographic and design effects (cooking, treatment, muscle etc) effects on sensory responses from Korean and Australian consumers

Conclusions  Korean consumers are more discriminating at the lower quality grades  The effects of hang, cook and cut on palatability were similar for Australian and Korean consumers  Korean consumers are more discriminating at the lower quality grades  The effects of hang, cook and cut on palatability were similar for Australian and Korean consumers

Implications  To Australia –The MSA model predicted palatability for Korean consumers –Potential for the MSA model to underpin an international language for meat quality  To Australia –The MSA model predicted palatability for Korean consumers –Potential for the MSA model to underpin an international language for meat quality

Demographic effects on Korean consumers  Factors tested –Region of Korea –Age of consumer –Gender –Occupation –How often do you eat meat –No. of adults in the household –No. of children in the household –How do you perceive beef –Level of doneness you prefer –Income bracket  Factors tested –Region of Korea –Age of consumer –Gender –Occupation –How often do you eat meat –No. of adults in the household –No. of children in the household –How do you perceive beef –Level of doneness you prefer –Income bracket

Demographic effects on Korean consumers  No demographic factors were significant for either Grill or Korean BBQ  Examples: GRILL MQ4 –Age effects Gender MaleFemale 5657  No demographic factors were significant for either Grill or Korean BBQ  Examples: GRILL MQ4 –Age effects Gender MaleFemale 5657

Implications  To Korea –The demographics of the Korean consumers did not impact on beef palatability –A consumer testing protocol for beef palatability to be used in Korea –The MSA model provides an opportunity to accurately predict palatability for Korean consumers  To Korea –The demographics of the Korean consumers did not impact on beef palatability –A consumer testing protocol for beef palatability to be used in Korea –The MSA model provides an opportunity to accurately predict palatability for Korean consumers
