This work was aimed to study the implication of different sensory methodologies (an analytical method by selected assessors, and two hedonic methods: Acceptability limit and Survival analysis), for determining the shelf-life of a pumpkin-orange cake. Hedonic methods were performed by two groups of consumers: group A performed acceptability test first, and then survival analysis, for the group B the order was reversed. Indeed, the survival analysis was also assessed by using a staggered design and by involving other consumers. By considering the results of both analytical method and hedonic method performed by group A, the estimated shelf-life was about 15 days, meanwhile, it ranged from 30 to 40 days, based on the results of hedonic methods performed by group B of consumers and the results of survival analysis performed by using the staggered design. Failure criteria based on consumer acceptability must therefore be accurately chosen to avoid shelf-life estimation that does not reflect consumer behavior. The combination of two sensory methodologies could be a fast way to get more information regarding both the acceptability and the reason why the consumers will accept or reject the product.

Abstract
This work was aimed to study the implication of different sensory methodologies (an analytical method by selected assessors, and two hedonic methods: Acceptability limit and Survival analysis), for determining the shelf-life of a pumpkin-orange cake. Hedonic methods were performed by two groups of consumers: group A performed acceptability test first, and then survival analysis, for the group B the order was reversed. Indeed, the survival analysis was also assessed by using a staggered design and by involving other consumers. By considering the results of both analytical method and hedonic method performed by group A, the estimated shelf-life was about 15 days, meanwhile, it ranged from 30 to 40 days, based on the results of hedonic methods performed by group B of consumers and the results of survival analysis performed by using the staggered design. Failure criteria based on consumer acceptability must therefore be accurately chosen to avoid shelf-life estimation that does not reflect consumer behavior. The combination of two sensory methodologies could be a fast way to get more information regarding both the acceptability and the reason why the consumers will accept or reject the product.File | Dimensione | Formato | |
