This study aimed to determine the impact of ancient wheat varieties (emmer. spelt and khorasan) and spontaneous sourdough fermentation on the bioaccessibility of total phenolic content (TPC) and the DPPH antioxidant capacity evolution during breadmaking and in vitro digestion. Sourdough and yeast-fermented modern wheat breads were used as controls. After 6 h of fermentation. https://parisnaturalfoodes.shop/product-category/cheddar-style-slices/
