| 摘 要： | 为运用概率分级和回归分析方法揭示普通丝瓜褐变度与总酚含量之间的相互关系,从而建立普通丝瓜基于褐变度正态分布的分级标准,研究测定38份普通丝瓜的褐变度和总酚含量。采用X-1.2818S、X-0.5246S、X+0.5246S和X+1.2818S 4个点将丝瓜褐变度概率分为5级,即极低(1级)、低(2级)、中(3级)、高(4级)、极高(5级),并将其与总酚含量进行线性回归分析。普通丝瓜果肉褐变度变化范围为2.17~9.60,平均值为6.211,变异系数为29.77%,经K-S正态性检验符合正态分布,建立褐变度和总酚含量的线性回归方程y=3.559x-2.837,两者之间存在显著的线性关系。普通丝瓜果肉褐变度与总酚含量呈显著正相关。

Probability Classification of Luffa Browning Degree and Its Regression Analysis with Total Phenol |
| |
| Abstract: | The research aims to use the method of probability classification and regression analysis to reveal the relationship between luffa browning degree and its total phenol content, and establish a standard luffa grade based on normal distribution of the browning degree. The browning degree and total phenol were determined among 38 luffa varieties. Furthermore, luffa browning probability was divided into five grades i.e., extremely low (1), low (2), medium (3), high (4), extremely high (5)] according to four points (i.e., X-1.2818S, X-0.5246S, X+0.5246S and X+1.2818S), and its linear-regression with total phenol was analyzed. The K-S normality testing results showed that the browning degree which ranged from 2.17 to 9.60 conformed to normal distribution, and had an average value of 6.211 and a variable coefficient of 29.77%. There was a significant linear relationship between luffa browning degree and total phenol, and a linear regression equation was established (i.e., y=3.559x- 2.837). The results showed that there was a significantly positive correlation between luffa total phenol and its browning degree. |
