摘要: (E)-10-hydroxydec-2-enoic acid (10-HDA) is the main fatty acid present in royal jelly (RJ). Among the criteria for royal jelly quality analysis, 10-HDA content has been proposed as a freshness parameter. In this study, 10-HDA content variations under controlled temperature storage, were evaluated as an aging indicator of RJ samples from two origins (France and Thailand). For a 12 month period, the 10-HDA content loss rates were 0.1 and 0.2% at− 18° C and 4° C, respectively, whatever the sample origin. At room temperature storage, losses …
