摘要： Although the antimicrobial, nutritional, and health-promoting properties of royal jelly (RJ) have been widely confirmed, the effects of storage temperature and time on RJ quality remain to be further explored. Herein, the antimicrobial and proteomic dynamics of RJ stored under different conditions were comprehensively investigated to identify consistent and sensitive markers of RJ degradation. We confirmed the negative correlation between antimicrobial properties and increased the storage temperature and duration in RJ. Using surface plasmon resonance, we showed the protein degradation-induced conformation changes in RJ, which reflected the overall variation in RJ proteins caused by the storage conditions. Further proteomic and western blotting analyses demonstrated the sensitivity and reliability of major RJ protein 4 (MRJP4) as a measure of temperature- and time-dependent RJ changes. Based on these results, we developed a colloidal gold immunoassay strip for MRJP4 detection, providing a reliable, simple, and rapid method for the evaluation of RJ freshness.
