One possible approach to understand consumer perception and
purchase decisions of food products is the application of qualitative
techniques (Roininen et al., 2006). These techniques involve
tasks that are less structured than quantitative approaches, such
as surveys based on fixed questionnaires, and thus allow deeper
probing of consumer behaviour (Lawless & Heymann, 2010). They
are appropriate to identify market opportunities, generate ideas
and hypothesis, explore and develop new concepts, and understand
consumer perspectives prior to quantitative research (Lawless
& Heymann, 2010).
