AB  - Xylooligosaccharides (XOS) and arabinoxylooligosaccharides (AXOS), potential 
      prebiotics, can be produced from rice bran arabinoxylan (RBAX) using commercial 
      endoxylanase enzymes. However, differences in rice bran cultivars and 
      endoxylanase enzyme types may affect extracted oligosaccharides (OS) yields. This 
      study investigated extracted OS structures derived from three different RBAX 
      using two commercial endoxylanase enzymes. RBAX extracted from commercially 
      defatted rice bran (CDRB) yielded the greatest OS amount (456.69 mg/g RBAX), 
      followed by that of the San-Pah-Tawng1 (SPT1) cultivar (231.7 mg/g RBAX), and 
      lastly, the Chai-Nat1 (CN1) cultivar (172.57 mg/g RBAX), as evidenced via 
      Ultraflo L enzyme hydrolysis. Ultraflo Max enzyme hydrolysis produced a similar 
      trend, however, OS amounts from all RBAX sources were remarkably lower (83.39 
      mg/g RBAX extracted from CDRB, 27.05 mg/g RBAX from SPT1 cultivar, and 21.53 mg/g 
      RBAX from CN1 cultivar). Interestingly, 3(2)-alpha-L-Araf-(1-4)-beta-D-xylobiose (A(3)X) 
      was the primary AXOS product in all RBAX hydrolysates prepared by Ultraflo Max. 
      RBAX extracted from CDRB solubilized by Ultraflo L (45.67% weight of RBAX) had 
      higher OS yields than that obtained via Ultraflo Max (8.3% weight of RBAX). 
      Ultraflo L was therefore a suitable commercial enzyme for short-chain OS 
      conversion from RBAX.
