Abstract

The quality of agricultural produce, such as fruit and vegetables, is defined by grading criteria based on the assessment of primary product attributes determined at harvest. These quality measures, which characterize important end-product intrinsic attributes such as flavor and texture, are used by processors and retailers to differentiate retail products; hence they determine farm-gate and retail prices for each crop variety. Despite their importance, limited published research has systematically linked these attributes at harvest to consumer preference at retail level. In this article, we adopt a demand system, the Almost Ideal Demand Systems, to assess the effects of the intrinsic quality attributes on consumers' purchase choices across six different quality grades that relate to 41 vegetable products sold by a leading United Kingdom (UK) retailer over a two year period. Findings suggest that consumers are both able to differentiate products based on the attributes determined at harvest and willing to pay a premium for these attributes. These findings are relevant to both industry and public health practitioners intending to maintain or expand demand for vegetables in the UK. (C) 2014 Elsevier Ltd. All rights reserved.
