基于总糖/纤维素的配方烟丝均匀度评价方法建立及应用
|
摘要
为客观准确地评价配方烟丝中烟丝、再造烟叶、梗丝混配均匀度,建立了基于总糖/纤维素理论值和实际值差异的配方烟丝均匀度评价方法,通过构造不同再造烟叶、梗丝添加比例,对所建方法进行评价、应用和对比。结果表明,总糖和纤维素在烟丝、再造烟叶和梗丝中含量分布各不相同,总糖:烟丝>梗丝>再造烟叶,纤维素:再造烟叶>梗丝>烟丝。在试验范围内,采用总糖和纤维素作为均匀度评价的指标具有较好的灵敏度和准确度,当设定再造烟叶和梗丝掺配比例在5%～15%时,纤维素/总糖和总糖/纤维素对掺配比例变化的灵敏度为32%和40%,当实掺再造烟叶和梗丝掺配比例为6%～9%时,总糖和纤维素的实际检测值与理论预测值之间相对差值均<1%。与YC/T 426—2012标准对比,该方法实用性较好,在实际生产中可作为一种补充方法对配方烟丝均匀度进行判定。
In order to objectively and accurately evaluate the uniformity of cut tobacco,reconstituted tobacco and cut stem in tobacco formula,this paper established a method for evaluating the uniformity of tobacco formula based on the difference between the theoretical value and the actual value of total sugar/cellulose.This method was evaluated, applied and compared by constructing different proportion of reconstituted tobacco and cut stem.The results showed that:The content of total sugar and cellulose in cut tobacco,reconstituted tobacco and cut stem is different.Total sugar:cut tobacco>cut stem > reconstituted tobacco,cellulose:reconstituted tobacco > cut stem > cut tobacco.In the experimental range,the use of total sugar and cellulose as indicators for uniformity evaluation has good sensitivity and accuracy.When setting the ratio of reconstituted tobacco and cut stems to 5% to 15%,The sensitivity of cellulose/total sugar and total sugar/cellulose is 32% and 40%.When the blending ratio of actual reconstituted tobacco and cut silk is 6% to 9%,the relative difference between the actual detection value and theoretical prediction of total sugar and cellulose is less than <1%.By evaluated the uniformity of the tobacco formula in the silkmaking process and compared with the standard method YC/T426—2012,our method has good practicability and can be used as a supplementary method to determine the uniformity of the cut tobacco in actual production.
