  1. aCompound quantified as μg/g DW of the corresponding standard.
  2. bCompound quantified as Meqv rutin/g DW.
  3. Germination was carried out for 0 (day 0), 3 (day 3), and 5 (day 5) days, and subsequently subjected to simulated gastrointestinal digestion (Day 5 + SGID). Fermentation was carried out for 0 (flour) and 48 h (F + SSF), and the fermented flour was subsequently subjected to simulated gastrointestinal digestion (F + SSF + SGID).
