ABSTRACT: This performed a technical application of tamarind residues (peel and seeds) in a habitually-consumed food product (cookie) and to verify its sensory and market acceptance. We initially proceeded by preparing the peel flour and roasted seeds by conventional drying. Then, the flours were physico-chemically characterized. Next, the products were prepared; cookies were prepared replacing wheat flour with peel flour (PF0, 15 and 30%), and a second kind of cookie was made by replacing wheat flour with roasted seed flour (SF0, 15 and 30%). Affective tests (hedonic scale, attitude and ordering) and purchase intention were subsequently evaluated to verify sensory acceptability. All cookies generated high energy value. The fiber content was higher in the incorporated formulations compared to the standards. The highest sensorial acceptance mediansfor the peel flour cookies were for the standard cookie and the cookiewith 15% peel flour, which were statistically equivalent. Conversely, the cookie with 30% peel flour had lower medians compared to the others. Other tests also revealed better scores for standard formulations and 15%peel flour. There was no difference in the medians by the hedonic tests, attitude and purchase intentionfor cookies prepared with roasted seeds, presenting scores indicating high sensory and market appreciation. It is concluded that it is possible to incorporate tamarind peel flour and roasted seeds in cookies and add nutritional value, especially at a concentration of 15%.
