Quantitative-descriptive analysis (QDA) method was used to assess the products. At each time (,, 0 3 6 months). A total of. Six sessions were carried out. For each, daily session five samples were presented Each sample, was evaluated in triplicate.? Samples were coded with three-digit randomized numbers and served in random order according to sample. Replicate and, assessor. For, each sample six 4.5 mm slices (two for appearance three for, taste and texture and one for rancid off flavor and odor). Were obtained using a commercial slicing machine and were immediately served to the parielists. After sensory, profiling. The panelists were asked to score each sample for rancid off-flavor and odor both the, slices and the plants were at room. Temperature (20-23 C). Panelists were asked to drink a sip of still water at the beginning of the sensory evaluation and. To eat unsalted crackers between samples to try to make the palate conditions similar for each sample. Attributes were rated. On the basis of 100 mm unstructured lines with anchor points at each end (0 =, = absent 100 very strong), tests were performed. At about 10.00 a.m. In a controlled sensory analysis laboratory (ISO, 8589 2007). Equipped with individual booths and under. Red lighting to mask color differences in the samples. Except during the evaluation of sausage appearance. When white fluorescent. Lighting was used. The panelists were not provided with any information regarding the samples to be tasted. The interval. Between samples was approximately 10 min.2.3.3. Consumer testing.A total of 102 consumers with an average age of 32 years and with a balanced distribution with respect to gender participated. In the test. Consumers were recruited by phone among regular eaters of sausages (defining as consuming the product at least. Once a week). In addition they had, to meet other criteria such as not reporting any conditions affecting the senses of. Taste or smell and being, available over the study period. Each participant evaluated ten samples (one 4.5 mm slice for. Each sample only after, 3 months of storage) in a controlled sensory analysis laboratory as described for QDA under white. Fluorescent lighting. Two sessions were conducted at 1 h interval; for each session five samples were presented in randomized. Order. They were asked to drink a sip of still water at the beginning of the sensory evaluation and to eat unsalted crackers. Between samples to try to make the palate conditions similar for each sample. For, each product consumers expressed an overall. Liking and a liking according to the following sensory inputs: appearance taste / flavor, and texture. Consumers rated their. Liking on a 9-point hedonic scale labeled at the left end with "extremely unpleasant" (1), at the right end with extremely. " Pleasant "(9) and at the central point with" neither pleasant nor unpleasant "(K ä HK ö Nen Tuorila & Rita 1996,,,).
