Study on Osmanthus fragrans wine's extraction and nutrient compoments

In order to explore the different extractive conditions and nutrient compoments of Osmanthus fragrans wine,we took the white spirit and fresh petals of Osmanthus fragrans to produce the different concentrations Osmanthus fragrans wine using different alcoholic degrees and solid-liquid ratios. Then,obtained the best extractive condition of Osmanthus fragrans wine by principal component analysis.The results showed that the best Osmanthus fragrans wine extractive condition was soaking the petals into the 66 degree alcoholic under the1∶ 20( kg ∶ L) solid-liquid ratio for six months. In this condition,the contents of each nutrient compoments were the highest( total flavonoids 1.14 g,anthocyanin 7.49 mg,vitamin C 39.9 mg,total sugar 2.58 g,Fe 1.14 mg,Mn 0.17 mg,Zn 0.94 mg,Cu 0.23 mg,Mg 7.69 mg,Ca 2.91 mg). Taken together,this study had achieved the preliminary screening of Osmanthus fragrans wine extractive condition and would be helpful for the further exploration of Osmanthus fragrans wine.
