Fatty acids composition of stale sourdough bread based on dry weight before and after 6 days solid state fermentation by N. intermedia. Fatty acid (FA) composition, total FA, total saturated fatty acids (SFA), total monounsaturated fatty acids (MUFA), and total polyunsaturated fatty acids (PUFA) in stale sourdough bread based on dry weight referred as ‘before’ fermentation begins, after 6 days solid state fermentation (whole fermentation period) by N. intermedia referred as ‘after’ and on BSG as a potential substrate. Essential Fatty acids in human are highlighted with gray.
