Abstract

Purpose – Domestic preparation practices influence the sensory properties and nutritional composition of food products. Information on the variability in actual domestic preparation practices is needed to assess the influence of applied conditions on the sensory and nutritional quality of food. The collection of such information requires a reliable, valid and practical research method. The paper aims to discuss these issues. Design/methodology/approach – Direct in-home observations, observations in a model-kitchen using cameras, and a self-reporting questionnaire were evaluated for reliability and validity, to study domestic food preparation practices by consumers. Broccoli preparation practices by Dutch consumers were checked by these three methods in this research paper. Findings – All three research methods were found to be test-retest, inter-observer, parallel-form reliable; and face, content and concurrent valid. However, the self-reporting questionnaire is the most practical research method that can be administered on a large number of respondents in a short time to capture the wide variations in preparation practices. Originality/value – Consumers can be assisted on domestic food preparation practices that reach their sensory preferences (e.g. texture, colour) as well as have health benefits on consumption.
