[Objectives]This study to conducted to clarify various nutritional components and the composition and contents of aromatic substances in mulberry wine prepared by fermentation,and promote the quality improvement and product development of mulberry wine.[Methods]Mulberry wine was prepared with mulberry Shengguo 1 as the material using Saccharomyces cerevisiae,and its contents of total sugars,total phenols,total acids,resveratrol,protein,dry extract,ethanol content,Fe,methanol,sulfur dioxide,volatile acids,total flavonoids and proanthocyanidins were determined.Aromatic substances were extracted by n-hexane,and their components and relative contents were determined by gas chromatography-mass spectrometry(GC-MS).[Results]The physical and chemical indexes of the mulberry wine prepared by fermentation were in accordance with the national standards,and it was rich in resveratrol(10.5±0.6 mg/L),protein(381±11 mg/L),total flavonoids(406±18 mg/L)and proanthocyanidins(855±22 mg/L),which were 8.95,19.49,3.76 and 1.63 times higher than those of grape wine,respectively.The aromatic substances were mainly composed of ethyl formate(9.9%),ethyl acetate(7.6%),acetal(6.2%),propanol(5.7%),isobutanol(5.6%)and isoamyl acetate(5.3%).[Conclusions]The results of this study demonstrated that mulberry wine was rich in active substances,which suggested that mulberry wine has great potential in the fruit wine market. 展开更多
