Aroma compounds and physicochemical and functional properties of traditional Tokat bread.

This study aimed to determine the physical (height, weight, volume, color, etc.), chemical (protein, fat, ash, moisture, etc.), functional (total phenolic, flavonoid, and antioxidant capacity), nutritional (total, soluble, insoluble dietary fiber, and important starch fractions), and texture properties and volatile organic compounds of traditional Tokat bread. In addition, yeast and bacterial species were isolated and identified from the sourdoughs used in its production. Having a 6-day shelf life, traditional Tokat bread has an average total dietary fiber content of 14.64%. The predictable glycemic index was 83.09, and the slowly digestible starch content was 6.15%. In traditional Tokat bread, 45 different volatile aroma components were identified, and . , . , . , . , and . species were mostly isolated in sourdough. The characteristics of traditional Tokat breads produced by traditional methods in different regions were determined. It is predicted that the taste and aroma of traditional Tokat bread originate from the hornbeam and pelite woods used in the baking stage and the sourdough used. The yeast composition of the breads collected from different regions also varies.
