Abstract: In this study, in vitro digestion and fermentation was employed to simulate the consumption of fermented okara and hence, evaluate its potential as a functional food ingredient. This is to develop a method of utilizing okara without producing secondary waste. Fermentation increased the amount of soluble dietary fiber by 187%. Bioaccessibility of amino acids, fatty acids, and vitamin K2 MK-7 is higher in the digestion supernatant of fermented okara. Bacillus subtilis also remained viable after digestion. Supernatants of fermented okara exhibited higher bio accessibility of total phenolic content and higher DPPH radical scavenging activity in the small and large intestines. Similarly, the concentrations of acetic acid, propionic acid, and butyric acid were 44.4%, 46.9%, and 51.8% higher, respectively. The gut microbiota was also found to be different in the fermentation supernatants between fermented and unfermented okara. Results demonstrated the potential of fermented okara as a functional food ingredient.
