Abstract:In order to explore the basic nutrients in commercially available blueberry wine, polysaccharide components from 10 commercially available blueberry wines were isolated and extracted, their content and monosaccharide composition were determined, at the same time, the organic acids and vitamins contents were analyzed by high performance liquid chromatography. The contents of nutrients such as total phenols, total flavonoids, and total anthocyanins were determined by chemical methods. It was shown that the polysaccharides in most commercially available blueberry wines had multiple components, with mannose, arabinose, and galactose being the main monosaccharides, similar to the composition of blueberry polysaccharides. High levels of organic acids, such as quinic acid (271.73~10693.36 μg/mL), lactate citric acid (67.65~1766.40 μg/mL), and malic acid (151.53~6006.40 μg/mL), were found in the 10 commercial blueberry wines. The contents of vitamin B1, vitamin B2, and vitamin B6 in the blueberry wines ranged from 0.08 to 2.89 mg/100 mL, 0 to 4.35 mg/100 mL, and 0 to 4.95 mg/100 mL, respectively. Additionally, the contents of total phenols, total flavonoids, and total anthocyanins in the 10 blueberry wines ranged from 0.18 to 1.65 mg/mL, 0.29 to 3.48 mg/mL, and 3.47 to 117.27 mg/L, respectively. By comparing various ingredients and their contents, it was found that No. 4 blueberry wine contained more types and better content of vitamins and had a significantly higher content of phenolic substances than the other blueberry wines, indicating the best quality. Overall, the nutritional composition of blueberry wine was preliminarily revealed, laying the foundation for further investigation of its biological activity.
