Interpretive Summary: Modified atmosphere packaging (MAP) has been used to retain the quality of postharvest produce. In the present study the effect of MAP on quality of berry fruit of Sea buckthorn (Hippophae rhamnoides L., a hardy, deciduous shrub, native to Asia) during refrigerated storage was investigated. Sea buckthorn berries were packaged in vented clamshell containers (air control), 160 OTR or 525 ORT bags and stored at 10oC for 10 days. The packaging effects on berry quality were indicated by the changes in headspace compositions, moisture contents, pH, color (CIE L*, a* and b* values), Total soluble solid (TSS), texture (springiness and hardness), and antioxidant activity (capacity of scavenging hydroxyl free radical and inhibiting oxidation of 2,2'-azino-di-(3-ethylbenzthiazoline)-6 sulfonic acid) during storage. Our results show that O2 content at equilibrium was below 2% in 160 OTR bags and 16% in 525 OTR bags, respectively, and CO2 was 18% in 160 OTR bags and 3% in 525 OTR bags. There were no significant differences between three package treatments for pH, moisture contents and texture by the end of storage. However, color, TSS, and the antioxidant activity of fruits were higher in MAP treated samples, especially 160 OTR packaging, than the air control. These results demonstrate that MAP affects the quality of sea buckthorn berries and can be used to retain the fruit antioxidant activity during postharvest storage and could be used to extend the marketlife for commercial distribution. Key words: packaging, MAP, berry fruit, market quality
