- Abstract
The present study evaluated the quality and freshness of royal jelly by determining superoxide dismutase (SOD) activity in royal jelly using the xanthine oxidase method, to optimize royal jelly pretreatment, and compare variations in SOD activity in royal jelly under different storage times and temperature conditions. Furthermore, SOD activity in royal jelly products associated with different production processes and nectar sources were analyzed. The optimized pretreatment method involved diluting and dissolving the royal jelly samples in saline to three times the volume and centrifuging twice at 6 000 r/min and 4 ℃ for 20 min. The optimized pretreatment method was used to determine SOD activity in royal jelly. SOD activity decreased significantly with increases in storage time and temperature. Moreover, the production process and pollen sources for bees influenced SOD activity in royal jelly to some extent.
