In food industry, spices are mostly used to improve colour, odour, taste and aroma of different foods, and as antioxidants and antimicrobial agents. Spices come from different parts of plants, such as leaves, seeds, bark, fruits, roots, berries and pods. Sensory properties of different spices can be described with McCormick's spice wheel, which includes sensory descriptors for odour and aroma. In graduation thesis we have studied the use of spices in bakery products for improvement of colour and aroma, and antioxidant and antimicrobial activity. Also we wanted to investigate the effect of the addition of selected spices (anise, allspice, ginger and turmeric) on some sensory properties (appearance, odour, taste, aroma, fragility and solubility) and overall liking of cookies. The cookies were prepared with addition of spices and then sensory evaluated with a panel of students. The major differences between the cookies were in appearance, odour, taste and aroma. The control sample (without spices) received the highest scores for most sensory properties except for the appearance, where only cookies with ginger were evaluated better. In assessing the solubility and fragility of cookies the hedonic scores were comparable between the samples. In evaluating the overall likeness, the best results were obtained for the control, followed by cookies with anise and allspice, while the lowest scores were obtained for cookies with ginger and turmeric. Cookies with ginger received lower hedonic score because of spicy, burning aftertaste, whereas cookies with turmeric were evaluated lower because of too intense yellow colour.
