摘　　要：为分析不同片型复烤片烟色差、质体色素的差异性及变化,选择红大C3F、K326 B3F烟叶作为对象,利用叶片振动分选机分别对2种烟叶原料的复烤片烟进行筛分,并对不同片型复烤片烟色差参数L*(明度值)、a*(红度值)、b*(黄度值)、△E(总色差值)及质体色素(叶黄素、β-胡萝卜素)质量分数的差异、变化趋势以及色差参数与质体色素间的Pearson相关性、函数关系进行分析。结果表明:①对于红大C3F、K326 B3F复烤后片烟,不同片型间的色差参数L*、a*、b*、△E值及叶黄素和β-胡萝卜素质量分数总体均存在显著性差异。②随着片烟尺寸的减小,L*值呈先降低后升高的变化趋势,a*、b*、△E值及2种质体色素质量分数均呈先升高后降低的变化趋势,且4个色差参数及2种质体色素变化的拐点均为小片。其中,小片的L*值最低,a*、b*、△E值以及2种质体色素质量分数均为最高;碎末的L*值最高,但a*、b*、△E值以及2种质体色素质量分数均为最低。③叶黄素、β-胡萝卜素及其总量与L*值呈显著或极显著负相关,与a*、b*、△E值呈显著或极显著正相关;分别对2种烟叶原料不同片型复烤片烟的色差参数与质体色素总量进行回归分析,L*、a*、b*、△E值与质体色素总量之间均存在高度拟合的线性关系。对于同一等级烟叶,不同片型复烤片烟的色差和质体色素质量分数存在较大差异和规律性变化趋势。In order to establish the relationship between leaf color difference and plastid pigment in redried strips of different sizes,the threshed strips of Hongda C3F and K326 B3F tobacco leaves were sieved by a vibratory screen.The color difference parameters,L*(lightness value),a*(redness value),b*(yellowness value),△E(total color different)and the contents of plastid pigments(lutein,β-carotene)in redried strips of different sizes were measured and used to construct Pearson correlation and functional relationships between the color difference and plastid pigment contents.The results showed that:1)The redried strips had significant differences in the values of L*,a*,b*,△E,and also the contents of lutein,β-carotene.2)With the decrease of strip size,the value of L*decreased first and then increased;the values of a*,b*,△E and the contents of two plastid pigments increased first and then decreased,and the inflection points of the variations were in the small strips for the four parameters and the two plastid pigment contents.Among them,the L*value of the small strips was the lowest,while the a*,b*,△E values and the two plastid pigment contents were the highest.The L*value of tobacco dust was the highest,while the a*,b*,△E values and two plastid pigment contents were the lowest.3)The contents of lutein,β-carotene and their total content significantly or extremely significantly negatively correlated to L*value,and significantly or extremely significantly positively correlated to a*,b*,△E values.Regression analysis was carried out between the color difference parameters and the total content of plastid pigments,there was a highly fitting linear relationship between L*,a*,b*,△E values and the total plastid pigment content.For the tobacco leaves of the same grade,color difference and plastid pigment contents differed greatly among the redried strips of different sizes.
