摘要/Abstract

摘要： 以糯米为主要原料、板栗作为一种营养强化成分，按照传统黄酒的发酵工艺，酿制出一种具有丰富营养成分的新型板栗黄酒。通过乙醇分级沉淀法得到板栗黄酒多糖CWP，并使用超滤技术对其进行分离纯化，最终获得2 种具有不同多糖分子质量段的板栗黄酒多糖CWP-1（＞100 ku）和CWP-2（30～100 ku）。CWP-1和CWP-2主要由8 种单糖成分组成，包括半乳糖、甘露糖、葡萄糖、阿拉伯糖、木糖、岩藻糖、半乳糖醛酸和葡萄糖醛酸。红外光谱分析表明，2 种多糖均显示出多糖的典型吸收峰，并且CWP-1存在α-和β-糖苷键构型。体外免疫活性实验表明，CWP-1和CWP-2能够显著诱导小鼠巨噬细胞RAW264.7分泌肿瘤坏死因子-α、白细胞介素6和一氧化氮，并且其分泌细胞因子能力高于在相同质量浓度下的脂多糖。本研究结果将为板栗深加工产品开发和新型黄酒中功能性成分的研究和利用提供理论参考。

Abstract: Polysaccharides (CWP) from nutritious wine made from glutinous rice with added Chinese chestnut as a nutritional fortifier using the traditional fermentation process of Chinese rice wine (Huangjiu) were obtained by fractional ethanol precipitation and purified by ultrafiltration into two fractions: CWP-1 (> 100 ku) and CWP-2 (30–100 ku). CWP-1 and CWP-2 were mainly composed of eight monosaccharides, including galactose, mannose, glucose, arabinose, xylose, fucose, galacturonic acid and glucuronic acid. Infrared spectroscopy analysis showed the typical absorption peaks of both polysaccharides and the presence of α- and β-glycosidic bond conformations in CWP-1. In vitro immunological assays showed that CWP-1 and CWP-2 significantly induced the secretion of tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6) and nitric oxide (NO) by mouse macrophages RAW 264.7, and their capacity to secrete cytokines was higher than that of lipopolysaccharide (LPS) at the same mass concentration. This study will provide theoretical references for the research and utilization of functional components in chestnut processed Chinese chestnut products and new Huangjiu.
