Abstract: In order to provide a more reliable process for target temporal odour producing fragrance products, a computer-implemented method (100) is provided for generating a recipe profile of a fragrance product having a target temporal odour profile, wherein the fragrance product comprises a fragrance composition with one or a plurality of fragrance ingredient(s), the computer-implemente d method comprising the steps of: a) providing (110) the target temporal odour profile, wherein the target temporal odour profile comprises a time-dependent fractural amount of a plurality of odour families over a predetermined period of time, which is indicative of a desired evaporation behaviour of each odour family in the fragrance composition; b) providing (120), for each odour family, one or more fragrance ingredients having olfactive contributions matching the respective odour family; c) selecting (130) at least one ingredient from each odour family to form one or more recipes of the fragrance product, wherein each recipe comprises fragrance composition data associated with the fragrance ingredients of the recipe; d) determining (140) a temporal odour profile for each recipe; e) determining (150) a distance of each determined temporal odour profile of the one or more recipes to the target temporal odour profile of the fragrance product; f) selecting (160) at least one recipe from the one or more recipes that has a distance satisfying a predefined criterion; and g) providing (170) a recipe profile of the at least one selected recipe preferably usable for production of the fragrance product.
