摘　　要：为探究不同浓度的硫氢化钠(NaHS)处理对莲雾果实保鲜效果的影响,以莲雾果实为试材,分别经0.3、0.6、0.9、1.2 mmol/L的NaHS水溶液释放的H2S熏蒸处理,以蒸馏水熏蒸处理作为对照组,于4℃下贮藏,每2 d取样测定可溶性固形物含量、可滴定酸含量、硬度、呼吸速率、失重率和絮状绵软指数等指标,确定适宜的NaHS水溶液浓度。结果表明:与对照组相比,不同浓度NaHS处理的莲雾果实均具有较低的呼吸速率,较高的果实硬度、可溶性固形物含量和可滴定酸含量,较低的果实失重率和絮状绵软指数。其中,以0.9 mmol/L NaHS处理的保鲜效果最佳。因此认为,0.9 mmol/L NaHS处理可作为在4℃条件下贮藏采后莲雾果实的适宜条件。To investigate the effects of hydrogen sulfide(H2S)fumigation treatment released from different concentrations of aqueous sodium hydrosulfide(NaHS)solutions on the preservation of wax apple fruit.Wax apples were fumigated with H2S released by 0.3,0.6,0.9,1.2 mmol/L aqueous NaHS solutions,respectively(referred to as different concentrations of NaHS treatment),with distilled water fumigation serving as the control group,stored at 4℃,and samples were collected every 2 days for analysis.Various parameters including total soluble solid(TSS)content,titratable acid(TA)content,firmness,respiration rate,weight loss rate,and cottony softening index were tested to determine the appropriate concentration of NaHS aqueous solution.Results demonstrated that,compared to the control group,the fruit treated with different concentrations of aqueous NaHS solution had a lower respiration rate,a higher firmness,TSS,and TA contents while indicating a lower weight loss rate and cottony softening index.Among these treatments,0.9 mmol/L NaHS treatment exhibited the best preservation effect.Therefore,0.9 mmol/L NaHS treatment could be used as a suitable condition for storage of harvested wax apple fruit at 4℃.
