Abstract
PurposeThe article aims to address two questions: “What are the important extrinsic variables in consumer food studies?” and “Which are focused on the most?”Design/methodology/approachAn extensive search of previous literature was conducted to find data on papers related to extrinsic variables in food studies. Both an electronics search through computerized library databases (Web of Science, Food Science and Technology Abstract), and reference lists from relevant research papers were used.FindingsThe article finds that acceptance and intention to purchase measures regarding foods are associated with consumption and purchase process and are used as an indirect way of obtaining data to understand consumer behavior. Although the importance of intrinsic variables such as color, aroma, flavor and texture in food acceptance and choice are very well recognized, several studies have shown that other variables also play an important role in food acceptance, preference, choice and intention to purchase. This article presents the more studied extrinsic variables using the conjoint analysis and repertory grid methods.Research limitations/implicationsThis article shows data only on repertory grid and conjoint analysis. There are other methodologies such as focus group, laddering interviews and questionnaires that can be used to investigate the role of extrinsic variables on consumer attitude.Originality/valueContext variables are the most studied extrinsic variables. Production method, nutritional information, protected denomination of origin/certification and origin are some of these variables and are directly linked with consumer concerns about the product. The authors believe that the change in consumer behavior globally drives the search for motives that better explain choices.
