Summary: | Puffing process modifies the chemical and physical properties of the grains. In this study, oats were puffed by subjecting them to pressure of 1.0 and 1.2 MPa, following which the bioactive constituents and antioxidant activities in the oat extracts were investigated. The polyphenol content in puffed oat extracts increased in a pressure-dependent manner (109 and 157 mg gallic acid equivalent/100 g at 1.0 and 1.2 MPa, respectively). In addition, gallic acid was synthesized after puffing (518 µg/g of extract at 1.0 MPa) and was the most abundant phenolic acid in puffed oats. The antioxidant activities, which were determined by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2-azino-bis-3-ethylbenzothiazoline-6- sulphonic acid (ABTS) radical scavenging activities, were improved in oat extracts after puffing (+245 and +184% at 1.2 MPa, respectively). In conclusion, puffing process of oats increased the extractability of polyphenols, including gallic acid, which positively affected its antioxidant activities. These results will provide useful information when using puffed oats for food production. |
