Abstract

The present article covers a brief introduction on how repeated exposure design can be utilized for developing new food products. A generic consumer taste test which measures consumer acceptance in one trial may have limitation in predicting long-term acceptability of a product. The article describes the changes in food preference and choice during the course of life from infants to elderly. Then, several possible theories that proposes to delineate the underlying mechanisms for acquiring the liking for food is introduced. The article also discusses general experimental design, case studies which adopted repeated exposure design, the limitations and rapid test methods to predict long-term acceptance.

본고에서는 제품개발을 위한 소비자 조사에서 반복섭취 설계를 적용하는 접근법에 대해 살펴보았다. 제품에 대한 소비자 기호도는 비교적 역동적으로 변화할 수 있어 1회적 기호도 평가는 신제품에 대한 장기적 기호도 예측에 한계가 있다. 특히 시장이 형성되지 않은 제품군의 신제품에 대한 소비자의 기호도를 측정하기 위해서는 반복섭취 설계가 유용할 수 있다. 식품에 대한 반복섭취 설계는 익숙한 식품보다는 새로운 식품에서의 기호도 형성을 연구하는 것이 효과적이다. 다만 반복섭취 설계에 특성상 비교적 오랜 시간이 소요되기 때문에 실험진행자와 대상자 모두에게 어려운 설계이기도 하다. 향후 장기적인 기호도 변화에 대한 보다 빠르고 정확한 예측이 가능한 실험기법의 개발이 필요한 실정이다.
