中文摘要:

      目的 对目前市售的红谷黄酒类产品(无其他辅料添加)的营养价值及安全性进行分析评价。方法 采用比色法对产品的总蛋白、总多糖、总多酚、总黄酮、总皂苷、尿素含量及自由基清除能力进行测定, 利用高效液相色谱法对γ-氨基丁酸(γ-aminobutyric acid, GABA)、苯甲酸及生物胺(biogenic amine, BA)含量进行测定, 比较市售红谷黄酒产品的组间差异以及与其他类型黄酒产品的异同。结果 市售红谷黄酒产品拥有较高的营养价值, 其中SC品牌黄酒具有较高的GABA与总皂苷含量, GC品牌黄酒具有较高的总多酚与总黄酮含量, 同时具有最佳的体外抗氧化能力。从安全性角度分析, 除SC品牌黄酒中总BA含量较高外, 其余市售红谷黄酒产品的BA含量以及所有产品的尿素含量均处于较低水平, 苯甲酸均未检出。结论 市售红谷黄酒产品相较于其他原料酿造的产品, 具有更高的营养价值与较强的抗氧化性能, 且产品的总体饮用安全性较高。本研究明确了红谷黄酒的产品优势, 为红谷黄酒的推广提供数据支撑。

英文摘要:

      Objective To analyze and evaluate the nutritional value and safety of the currently commercial red millet Huangjiu products (without other additives). Methods The content of total protein, polysaccharides, polyphenols, flavonoids, saponins, urea and free radical scavenging capacity of the product were determined by colorimetry, and the content of γ-aminobutyric acid (GABA), benzoic acid and biogenic amine (BA) were determined by high performance liquid chromatography. The differences between the groups of commercial red millet Huangjiu products and other types of Huangjiu products were compared. Results The commercial red millet Huangjiu products had high nutritional values, among which SC had highest GABA and total saponin content, GC had highest total polyphenol and total flavonoid content, and also had the best in vitro antioxidant capacity. From the perspective of safety, in addition to the high content of total BA in SC, the BA content and urea content of all products sold in the market were at a low level, no benzoic acid was detected. Conclusion Compared to products brewed from other raw materials, the commercially available red millet Huangjiu products have higher nutritional value and stronger antioxidant properties, and the overall drinking safety of these products is relatively high. This study clarify the product advantages of red millet Huangjiu and provide data support for its promotion.
