The aim of this study was to produce a fermented rice bran extract with enhanced ferulic acid γ-oryzanol contents and high antioxidant activities. The ferulic acid content in the freeze-dried extract of rice bran treated with plantase PT enzyme, increased by 4.1-fold compared to that of untreated sample, the DPPH radical scavenging activity also increased by 1.5-fold and 1.2-fold, respectively. The γ-oryzanol content of the dried powder prepared by inoculating Apergillus oryzae BOT1869 onto steamed rice bran for solid-state fermentation followed by extraction with 80% ethanol, increased 2.3-fold compared to that in an 80% ethanol extract powder of raw materials. The ABTS scavenging activity also increased 1.5-fold. When the ferulic acid content-enhanced extract and the γ-oryzanol content-enhanced extract of rice bran were mixed and subjected to liquid fermentation with Lactiplantibacillus pentosus BOT406 and then freeze-dried, the ferulic acid content of the extract powder increased about 3.0 times compared to that of original extract powder. In addition, its γ-oryzanol content increased about 1.5 times, the DPPH radical scavenging activity increased 1.4 times, and the ABTS radical scavenging activity increased 1.6 times.
