Abstract:		"Fig (Ficus carica L.) is an excellent source of sugars, dietary fibers, minerals, vitamins, organic acids and phytochemicals. The aim of the present work was to investigate the effect of fig powder supplement, as a natural sweetener and flavoring agent, on the physicochemical, microbiological and sensory characteristics of goat's milk yogurt. It aimed also to determine antioxidant capacity and volatile profile using gas chromatography/mass spectrometry (GC/MS) analysis. Pyrolysis-GC/MS (Py-GC/MS) was also used for the characterization of fig powder. Fig powder exhibited an important antioxidant activity against DPPH(.) Radical (IC(50) = 1.92 +/- 0.05 mg per mL). Volatile compounds, from several classes (acids, alcohols, aldehydes, esters, triterpenoids and others) were identified in fig powder. Py-GC/MS data revealed that degradation of fig powder macromolecules leaded to the formation of several aromatic and volatile compounds such as fatty acids, ketones, aromatic phenols, lactones among others. The addition of fig powder increased significantly (p < 0.05) the titrable acidity, the total solids, the carbohydrate content, and the total lactic acid bacteria count of yogurts. Likewise, fig powder supplement improved yogurt taste, texture and aroma and covered the unpleasant flavor of goat's milk. Thus, fig powder is a natural sweetener and flavoring agent that can be used to formulate a new stirred goat's yogurt of good quality"
