The effects of puffing on the ginsenoside composition as well as antioxidant and anti-inflammatory activities of ginseng berry were investigated to increase the utilization of ginseng berry. There was no significant difference in extraction yield between the control and puffed samples at all moisture contents and pressure conditions (p < 0.05). Major ginsenosides of ginseng berry (especially ginsenoside Re) were degraded through deglycosylation and dehydration by heat and pressure, and new minor ginsenosides (Rg3, F2, Rh2 and Rb2) were produced after puffing. Puffed ginseng berries showed higher total phenolic content (TPC), total flavonoid content (TFC) and Maillard reaction products (MRPs) than those of the control group, and these contents were increased as puffing pressure increased. In addition, higher antioxidant activities were observed in puffed ginseng berries compared to the controls, possibly due to the increase in TPC and MRPs. Antioxidant activity increased with increasing puffing pressure at all moisture contents. Nitric oxide (NO) production showed no significant inhibitory effect between control and puffed ginseng berries (p < 0.05). In the case of inflammatory cytokines, IL-6 had an inhibitory effect, but TNF-α had no inhibitory effect. Consequently, puffing showed a positive effect on the composition and the transformation of ginsenosides as well as the antioxidant activity of ginseng berries, suggesting that puffed ginseng berries can be used as a high value-added food material.
