摘　　要：为了能快速判断出再造烟叶在线生产中原料的提取情况,采用实验室模拟生产的方法对再造烟叶原料进行提取后用手持折光仪测定提取过程中提取液的Brix值(可溶性固含量),并利用经典方法计算出原料提取率和提取液固含量,分析了提取液Brix值与固含量、提取率的相关性。结果表明,梗组原料提取液固含量为3.81%~7.21%时,Brix值与固含量有良好的线性关系(R^2=0.910 4);梗组原料提取率为24.10%~39.25%时,Brix值与提取率的线性回归方程R^2为0.819 6。当叶组原料提取液固含量为3.02%~6.55%时,提取液Brix值与固含量的线性回归方程R^2为0.956 9;当叶组原料提取率为20.14%~49.21%时,提取液Brix值与提取率的回归方程R^2为0.895 8。这说明在一定的提取范围内提取液Brix值与固含量和提取率有显著的正相关关系,在生产上可以通过快速测定提取液的Brix值来判定提取程度,并进行实时调控。In order to judge the extraction of materials in the online production of reconstituted tobacco quickly,the raw materials of reconstituted tobacco leaves were extracted by the method of laboratory simulation production.Brix value(soluble solid content)of the extract of paper-making reconstituted tobacco was measured by hand-held refractometer,and the extraction rate and solid content of the extract were calculated by classical method,and then the correlation between Brix value,solid content and extraction rate was analyzed.The results showed that there was a good linear relationship between Brix value and solid content in the range of 3.81%-7.21% in the stem group(R^2=0.9104);R square of linear regression equation between Brix value and extraction rate was 0.8196 in the extraction rate of the stem group was 24.10%-39.25%.R square of linear regression equation between Brix value and extraction rate was 0.9569 in the range of 3.02%-6.55% in the leaf group;when the extraction rate of leaf group was between 20.14% and 49.21%,R square of linear regression equation between Brix value and extraction rate was 0.8958.The results showed that there was a significant positive correlation between Brix value and solid content and extraction rate within a certain extraction range.In production,the extraction degree can be determined by rapid determination of Brix value of extraction solution,and real-time regulation can be carried out.
