摘　　要：为探究不同生物保鲜纸对采后百香果贮藏品质的影响。以百香果为研究材料,用不同处理的保鲜纸(800 mg/L纳他霉素、800 mg/Lε-聚赖氨酸)放入装有百香果的保鲜袋中,在(20±0.5)℃条件下贮藏,研究不同保鲜纸处理对采后百香果贮藏期果实品质的影响。结果表明,纳他霉素和ε-聚赖氨酸保鲜纸均能够抑制失重率、皱缩指数、相对电导率和丙二醛含量的增加,能有效维持果实的好果率、可溶性固形物(total soluble solids,TSS)含量、可滴定酸(titratable acid,TA)含量、维生素C含量、可溶性蛋白(soluble protein,SP)含量,且显著增强果实的超氧化物歧化酶(superoxide,SOD)活性,有效抑制果实霉菌及酵母菌的生长,较好地保持了百香果的贮藏品质。其中,在贮藏期20 d时,对照组、纳他霉素和ε-聚赖氨酸的百香果好果率分别为83%、90%、86%,纳他霉素的保鲜纸处理比ε-聚赖氨酸的保鲜纸效果更好,因此,800 mg/L纳他霉素保鲜纸更适宜百香果采后保鲜,能有效地保持百香果采后贮藏品质,并延长贮藏期。The work aimed to investigate the effect of different preservative paper on the storage quality of passion fruit.The passion was taken as the tested material,which was treated with different preservative paper(800 mg/L natamycin and 800 mg/Lε-polylysine)after harvest.The three groups of fruits were stored at(20±0.5)℃and the indexes were determined.The effect of natamycin andε-polylysine preservative paper on the quality of passion during postharvest storage was investigated.The results showed that compared with the control,natamycin andε-polylysine preservative paper could inhibit the increase of peel defect index,weight-loss ratio,malondialde-hyde content and relative conductivity.It also maintained good fruit ratio,total soluble solids content,titratable acid content,Vitamin C content and soluble protein content.Besides,the SOD activity of fruit was improved and the occurrence of fruit mold and yeast was re-duced.The good fruit ratio of passion fruits in groups CK,natamycin,ε-polylysine were 83%、90%、86%respectively after 20 days stor-age.Therefore,the preservation effect of the natamycin preservative paper treatment group was better than that of theε-polylysine preserv-ative paper treatment.
