    摘要： Processes and compositions are described for the use in foodstuff, chewing gum, toothpaste and medicinal product flavor and aroma and perfume aroma augmenting, enhancing, modifying and imparting compositions and as foodstuff, chewing gum, toothpaste, medicinal product, perfume and perfumed article aroma imparting materials of 1-(3,3-dimethyl-2-norbornyl)-2-propanone (hereinafter referred to as the "norbornylpropanone derivative") having the structure: ##STR1## (which structure is intended to cover both the "endo" and the "exo" isomers thereof). Addition of the said "norbornyl-propanone derivative" to consumable materials is indicated to produce:A. In foodstuffs, foodstuff flavorings, chewing gums, toothpastes and medicinal products, fruity/berry, pine needle-like aromas and sweet, fruity/berry, blueberry-like, pine needle-like, pine balsam flavor characteristics; andB. In perfumes, colognes and perfumed articles, sweet, berry, woody, piney, mint aroma notes with a damascenone-like character and buttery and minty nuances.
