摘　　要：Rose jam is a Chinese traditional food,usually preserved from rose petals and sugar.There were few metabolomics studies on rose petals accompanying pickling.We conducted a LC-MS/MS based metabolomics study to feature the dynamics profiles of rose jam nutrients.The rose jams with 10-,20-and 30-days’sugar-pickling under different sun-exposure gradients were analyzed.Ultimately,there were 838 and 213 rose jam metabolites being identified in positive and negative ion mode,respectively.And a total of 492 differential metabolites accompanying pickling were detected.The dynamic temporal profiles of rose nutrients revealed that metabolites in rose jams showed directional distribution according to sugar-pickle times and parallel distribution according to sun exposure gradients.The temporal features of the nutrients suggested that the sugar pickling process could remain most of rose nutrients and expand the diversity of them.These results revealed the influence of sugar ratio and exposure time on rose jams nutrition composition and might be used as a theoretical guidance for the process optimization of rose jams industrial standardization production.
