To provide a method of manufacturing shredded leaf midrib for improving whiteness of cigarette ash.SOLUTION: A method comprises a step (1) of eluting leaf midrib of tobacco as a raw material, a step (2) of repairing the leaf midrib of the tobacco after the elution treatment with glycerol so as to restore machining resistance strength of the leaf midrib of the tobacco, and a step (3) of removing the glycerol remaining in the leaf midrib of the tobacco and cutting the leaf midrib of the tobacco to obtain shredded leaf midrib. By adding to a cigarette and using the shredded leaf midrib obtained in the present invention, whiteness of the cigarette ash can be significantly improved by 15 to 30 units, an ash coagulation index can be lowered by 1 to 2 units, the change in the functional quality of the cigarette is small, and there is no safety concern. As compared with a method for improving the whiteness of cigarette ash by means of conventional leaf midrib cutting (rate of crushing is about 10 to 20%), the method is capable of controlling the rate of crushing to within 2 to 3% and significantly reducing the production cost.SELECTED DRAWING: Figure 1 【課題】紙巻きタバコの灰の白色度を向上させる中骨刻の製造方法を開示する。【解決手段】原料のタバコの中骨を溶出処理するステップ（１）と、タバコの中骨の耐加工性強度を回復させるように、溶出処理後のタバコの中骨をグリセロールで修復するステップ（２）と、タバコの中骨に残留したグリセロールを除去し、タバコの中骨を裁刻して中骨刻を得るステップ（３）と、を含む。本発明で得られた中骨刻を紙巻きタバコに添加して用いることにより、紙巻きタバコの灰の白色度を１５～３０単位著しく改善し、灰凝固指数を１～２単位低下させることができ、紙巻きタバコの官能品質の変化が小さく、安全性の懸念がない。従来の中骨刻の処理により紙巻きタバコの灰の白色度を向上させる方法（破砕率が約１０～２０％）に比べて、この方法は、破砕率を２～３％以内に制御し、製造コストを大幅に削減することができる。【選択図】図１
