In this paper we discuss how approach towards shelf life of food has evolved in recent decades along with the redefinition of ‘food quality’ term. Presented scenarios showed the idea of consumer-oriented approach in shelf life studies of food. Nowadays, the subject of interest is changing interaction food – consumer in relation to third factor − time. According to situation shelf life can be given as the length of time in which product maintains desired quality or functionality and then it is limited by time in which consumers still find food acceptable, or can be given as the length of time in which safety is maintained – if the second period is shorter than in the first situation. A shelf life assessment model based on consumer probability of food rejection was presented. It integrates data of objective measurements with consumer acceptability studies. Consumer-approach is visible today in the field of food commodity science, which concerns on consumers’ needs. Novel approach in shelf life studies, based on consumer perception of quality changes during storage integrates components such as commodity, producer and consumer, being thus fully in line with the scope of nowadays commodity science.
