A greater share of the stomach? Role of provenance and ethical standards on consumers’ food choices and purchasing intentions

Abstract

Purpose

Provenance and ethical standards reflect foods that traceable and are supportive of the environment, sustainability and justice in the food supply chain. The purpose of this study is to understand higher education consumers’ food choices and to examine the predictors of purchasing intention of food with provenance and ethical standards.

Design/methodology/approach

An online questionnaire was completed by 296 students and staff members of the University of Central Lancashire. The questionnaire collected information on socio-demographic profiles; food choices, provenance and ethical standards; ethical purchasing and sourcing requirements and purchasing intention of food products with provenance and ethical standards. Descriptive statistics were used to determine the frequency of distribution of all socio-demographic characteristics. Multiple regression was used to examine if attitude, perceived behavioural control and subjective norms of the Theory of Planned Behaviour (TPB) significantly predict the consumers’ purchasing intention (Step 1). Exploratory factor analysis was conducted on the behavioural items using principal components estimation and varimax rotation. Multiple regression on the expanded TPB (Step 2) using the obtained factor scores were conducted to determine if the factors were significant predictors of purchasing intention of food with provenance and ethical standards.

Findings

Multiple regression on the expanded TPB model revealed that only attitude and perceived behavioural control were significant predictors of purchasing intention of food with provenance and ethical standards. The regression model explained about 50 per cent of the variance of the intent to purchase food with provenance and ethical standards where R² = 0.50 (Adjusted R² = 0.47). This was significantly different from zero F (5, 89) = 17.77, p < 0.001. The incorporation of “Preference for ethically sourced food” and “Perceived knowledge and status of provenance standards” did not increase the prediction of purchasing behaviour.

Originality/value

Two broad themes were identified from the factor analysis where the first factor prioritises “Preference for ethically sourced food” and the second factor conceptualises “Perceived knowledge and status of provenance standards”. The TPB was expanded to incorporate both factors but did not increase the prediction of purchasing intention. The authors recommend that other potential predictors, for example, moral concerns or perceived value of food with provenance and/or ethical standards to be tested using an extended TPB framework. The study is of value to higher and further education catering services to encourage more sustainable and local food consumption.
