摘　　要：为延长鱼腥草鲜品和种茎的存放时间,促进鱼腥草人工栽培生产,选用3种不同保鲜试剂(草酸、焦亚硫酸钠和柠檬酸),应用单因素试验和正交试验设计,以蒸馏水为空白对照,研究3种试剂对鱼腥草感官品质和营养品质的影响。结果表明:贮藏7 d以后,草酸、焦亚硫酸钠、柠檬酸溶液对保持鱼腥草的感官品质有明显促进作用,褐变率在0%~45%;而对照处理鱼腥草腐烂严重,褐变率达65%;草酸对鱼腥草褐变的抑制效果最显著,焦亚硫酸钠能显著抑制不良气味的产生,柠檬酸对鱼腥草地下茎硬挺度的保持效果最好;当处理溶液为草酸50 mg/L、焦亚硫酸钠80 mg/L、柠檬酸350 mg/L组合时,鱼腥草在贮藏7 d后失重率最小,保水效果较好,贮藏保鲜效果最好,可为鱼腥草保存提供参考。In order to prolong the storage time of fresh products and seed stem,and promote artificial cultivation of Houttuynia cordata Thunb.,three different fresh-keeping reagents (oxalic acid,sodium pyrosulfite and citric acid) were selected to study the effects on the sensory quality and nutritional quality of H.cordata Thunb.by single factor experiment and orthogonal experiment design,with distilled water as blank control.The results showed that oxalic acid,sodium pyrosulfite and citric acid could significantly promoted the maintenance of sensory quality of the root of H.cordata Thunb.after 7 days of storage,with browning rate ranged from 0% to 45%,while serious decomposed in the control treatment,which browning rate reached 65%.Oxalic acid had the most significant inhibitory effect on the browning of the H.cordata Thunb.,sodium pyrosulfite could significantly inhibit the production of bad odor,and citric acid had the best effect on maintaining the stiffness of H.cordata Thunb..When the treatment solution was the combination of oxalic acid of 50 mg/L,sodium pyrosulfite of 80 mg/L and citric acid of 350 mg/L,the weight loss rate of the H.cordata Thunb.was the lowest after 7 days of storage,the water retention effect was better,and the storage preservation effect was the best,which could provide reference for the preservation of H.cordata Thunb..
