摘要:

研究山西老陈醋生产过程中酚类、黄酮类化合物含量及DPPH·清除能力的变化,并分析它们之间的相关性。结果表明:熏醅阶段总酚、总黄酮含量显著增加;总酚含量和总黄酮含量均与DPPH·清除率呈正相关,相关系数分别为0.9340 和0.9005;三者之间的多元线性回归方程(生产线2)为:Y=29.061+50.472X1+13.138X2,相关系数为0.954;总黄酮与总多酚含量之间也呈现较高的正相关性,其中生产线3 的相关系数为0.881。

Abstract:

The changes in contents of total phenolic compounds and total flavones and DPPH radical scavenging activity during Shanxi overmature vinegar production were investigated and the correlation among them was analyzed. Both the contents of total phenolic compounds and total flavones at smoking solid-substrate fermentation stage went up notably and were positively correlated with the DPPH radical scavenging activity and the correlation coefficients were 0.9340 and 0.9005, respectively. The multiple linear regression equation for the DPPH radical scavenging activity as a function of the contents of total phenolic compounds and total flavones was Y = 29.061 + 50.472X1 + 13.138X2 (production line 2), and the correlation coefficients 0.954. In addition, a high positive correlation was also found between the contents of total phenolic compounds and total flavones with the correlation coefficient of 0.881 (production line 3).
