Abstract
Over the past few years, fermented garlic and its extracts have been increasingly used in cooking and in the daily diet due to their specific taste, nutritional composition and health benefits. The fermentation process is performed by heat treatment of garlic with controlled humidity for a longer period of time. During fermentation, chemical reactions and transformations such as Maillard reactions and caramelization reactions cause the changes in taste, nutritional composition, content of macro- and microelements as well as the content of phenolic compounds and antioxidant activity of garlic. In this paper, samples of garlic and fermented garlic were analyzed and the content of phenolic compounds, antioxidant activity, macro- and microelements as well as nutritional composition were compared. The content of Ca, K, Mg, Na, Mn, Cu, Zn, and W increased, while the content of Fe, Al, Cr, Ni, Mo, Hg and Pb decreased during fermentation. The water content decreased during the fermen...tation process, while the sugar and carbohydrate content increased significantly as a result of thermal decomposition of the polyand oligosaccharides (fructan and other complex polysaccharides). Accordingly, the energy value of fermented garlic is higher than that of fresh garlic. The content of total phenolic compounds is higher in the fermented sample compared to fresh one, indicating different chemical transformations of secondary metabolites during the fermentation process. As a measure of antioxidant activity, two assays were performed: DPPH and FIC and both showed higher activity of fermented garlic, which is positively correlated with the higher content of phenolic compounds in the sample.

AB  - Over the past few years, fermented garlic and its extracts have been increasingly used in cooking
and in the daily diet due to their specific taste, nutritional composition and health benefits. The
fermentation process is performed by heat treatment of garlic with controlled humidity for a
longer period of time. During fermentation, chemical reactions and transformations such as
Maillard reactions and caramelization reactions cause the changes in taste, nutritional
composition, content of macro- and microelements as well as the content of phenolic compounds
and antioxidant activity of garlic. In this paper, samples of garlic and fermented garlic were

as well as nutritional composition were compared. The content of Ca, K, Mg, Na, Mn, Cu, Zn,

value of fermented garlic is higher than that of fresh garlic. The content of total phenolic
compounds is higher in the fermented sample compared to fresh one, indicating different
chemical transformations of secondary metabolites during the fermentation process. As a
