Postharvest browning of mushroom (Agaricus bisporus) reduces the shelf life of harvested mushrooms. Here, mushrooms were dipped in various solutions (distilled water; DW, 0.25% rice bran extract; RB, 0.1% ascorbic acid; AA, RB + AA) for 3 min. After air-drying at room temperature, the dipped mushrooms were packaged in a polypropylene (PP) films and stored at 4 or 15°C. The quality changes of mushrooms were measured in terms of color, gas composition, firmness, and sensory evaluation during storage. Rice bran extract was measured for total polyphenol content, total flavonoid content, DPPH, ABTS radical scavenging, chelating activity and PPO inhibition activity. No difference in firmness were found in the mushroom samples regardless of dipping solution or storage temperature. At both 4 and 15°C storage temperatures, RB + AA solution-dipped samples showed the highest L value and lowest delta E value. During the storage period, sensory evaluation showed that overall acceptability of mushrooms treated with RB and RB + AA solution was higher than that of the untreated mushrooms. Total polyphenol and flavonoid contents of 0.25% rice bran extract were 36.42 mg GAE･g -1 and 4.85 mg QE･g -1, respectively. The DPPH and ABTS radical scavenging activity of 0.1% ascorbic acid was higher than that of 0.25% rice bran extract. The highest copper (Cu 2+ ) chelating activity was found in the 0.25% rice bran extract. The PPO inhibition activity of 0.1% ascorbic acid was higher than that of 0.25% rice bran extract. Our results suggest that 0.25% rice bran extract with 0.1% ascorbic acid is effective anti-browning agent for maintaining quality of Agaricus bisporus during storage.

“…When the free radicals are produced excessively, however, immunerelated factors including lipid, protein, DNA, enzymes, and T-cell are damaged (Sternas et al, 1999). And it is reported that free radicals could cause tissue injuries, carcinogenesis, infl ammation, and aging (Oh et al, 2010). Recently, the infl ammatory reaction and existence of free radicals have been getting attention as a common mechanism of related injuries of gastric mucosa.…”

“…Such a huge amount of starting materials suggest that economically interesting yields could be achieved not only for major bran and germ components, such as γ-oryzanol, tocopherols, GABA, and polyphenols, but also for a number of lesser compounds (Oh, Kim et al 2010). In line with these opportunities, the development of industrial extraction of γ-oryzanol from rice bran and bran oil has been explored in different studies by using various solvents and supercritical fluid extraction M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 24 (Perretti, Miniati et al 2003;Patel and Naik 2004;Kaewboonnum, Wachararuji et al 2008;Jesus, Grimaldi et al 2010;Heidtmann-Bemvenuti, Nora et al 2012).…”
