摘要: 以葛根全粉为原粒，采用正交试验设计优化酶解反应体系参数，制备多孔葛根粉末，并经流化床制粒工艺得到多孔葛根颗粒，将所制备的多孔葛根颗粒添加到卷烟滤棒中可降低卷烟有害成分，改善卷烟感官品质.葛根全粉酶解制备多孔葛根粉末的最佳条件为：酶添加量0.8%，糖化酶与α-淀粉酶的质量比1：1，pH=5.5，反应温度50℃，酶解时间16 h.流化床制粒配方为：选取粒径>80目的酶解多孔葛根粉末作为制粒原料；m（羧甲基淀粉钠）：m（羧甲基纤维素）=3：5，浓度为8%的复配溶液作为制粒粘结剂.Abstract: Orthogonal test was investigated to optimize conditions of enzymatic hydrolysis for Pueraria with pueraria whole powder as material.Porous pueraria granule was prepared by fluid-bed granulation technology.The optimal enzymatic hydrolysis conditions were determined as enzyme concentration 0.8%,the mass ratio of glucoamylase and α-amylase was 1:1,pH value was 5.5,the reaction temperature was 50℃,and hydrolysis time was 16 h.Formulation factors of fluidized bed granulation processing were as follows:particle size of micro-porous starch was larger than 80 mesh as granulating material,and the optimized binder formulation contained 3 wt% sodium carboxymethyl starch and 5 wt% Sodium carboxymethyl cellulose mix solution.The prepared porous pueraria granule was added to cigarette filter rod to reduce the harmful ingredients in cigarette smoke and improve the cigarette sensory quality.
