Modelling perceived quality of tomato by structural equation analysis

Abstract

Purpose – This paper aims to further progress in research on perceived quality of fresh fruit and vegetables. It seeks to develop and discuss two models for perceived quality of tomato, including the price variable as an indicator for perceived quality of tomato. Design/methodology/approach – The data come from a survey of 400 consumers that measures the importance of a set of tomato attributes on a Likert scale. The models were adjusted by means of structural equation analysis. Two procedures were followed for model development: the first started from an exploratory factor analysis. In the second, relations and correlations among variables were established starting from the theoretical framework that differentiates among search, experience and credence attributes. Findings – Two models of tomato perceived quality are formulated and discussed. Both established that the perceived quality of fresh tomato could be explained through nine attributes. Some of them can be deduced at the place of purchase; some, during consumption while others are a question of trust. With regard to using price as an indicator of the perceived quality of tomato, both models suggested the elimination of this variable from the model for perceived quality. Originality/value – Studying perceived quality has received much attention in research on the behaviour of food consumers. Nevertheless, there are not many attempts to establish models for the perceived quality of fresh fruit and vegetables. Specifically, there are very few studies on consumer behaviour that analyse the perceived quality of tomato. Thus, this study is one of the first attempts to establish a model for perceived quality of tomato.
