Utilizing sensory evaluation to determine product shelf life
1979
Dethmers, A.E.
Storage studies to predict shelf life are an essential part of every product development, improvement, or maintenance program. Sensory evaluations of shelf life should be conducted by a sensory analyst who thoroughly understands the following factors: 1) purpose of the experiment; 2) physical and chemical composition of the test products; 3) formula, processing, and packaging treatment variables; 4) storage conditions; 5) projected storage life; 6) experimental design; 7) anticipated sensory change; and 8) sensory evaluation procedures. The factors involved in the selection of a particular sensory evaluation procedure and the determination of failure criteria are discussed. Practical applications of product shelf-life information include the establishment of the: 1) sell-by or pull date; 2) use-by or expiration date; and 3) freshness or quality assurance date.
