复合型保润剂对膨胀烟丝感官品质和保润性能的影响

Influence of compound humectant on sensory quality and moisture retentivity of expanded cut tobacco

为了研究复合型保润剂对膨胀烟丝的影响,采用膨胀前加料方式,按0.1%的施加比例加料制备膨胀烟丝,并进行物理指标、感官品质和保润性能对比.结果表明,添加复合型保润剂的膨胀烟丝与空白样品相比,物理指标得到明显提高,长丝率由43.4%提高到50.8%,整丝率由69.7%提高到74.1%,填充值由2.163 mm/g提高到2.463 mm/g,而碎丝率则由2.8%降低到2.1%;膨胀烟丝感官品质由65.0分提高到68.8分;保润性能得到明显改善,平衡含水率提高,失水速率降低.

In order to investigate the influence of compound humectants on expanded cut tobacco,casing mode before expansion was used.Expanded cut tobacco was prepared by 0.1%compound humectants and then expanded.Physical indexes,sensory quality and moisture retentivity were compared.The results indi-cated that：physical indexes were enhanced obviously,the long cut rate increased from 43.4%to 50.8%, the whole cut rate increased from 69.7% to 74.1%,the filling value increased from 2.163 mm/g to 2. 463 mm/g,the broken cut rate was reduced from 2.8% to 2.1%;sensory quality of expanded cut to-bacco increased from 65.0 point to 68.8 point;moisture retentivity was improved visibly,balanced mois-ture content was elevated and speed of dehydration was decreased.
