摘要
考察了开口箭根状茎石油醚提取物(A)、乙酸乙酯提取物(B)和正丁醇提取物(C)对水果致腐真菌(指状青霉、黑曲霉及匍枝根霉)的抑制效果,结果表明:B抑制真菌活性最强。以松香树脂(RAE)为被膜剂,研究了添加A、B、C为抑菌剂的3种保鲜剂AR、BR和CR对椪柑采后贮藏品质的影响,结果表明:A和B为抑菌剂添加在RAE被膜剂中能有效降低椪柑腐烂率,椪柑储藏36天后,添加AR和BR的涂膜处理组的腐烂指数分别为10.6%和7.2%,分别较未经任何处理的空白对照组(16.7%)降低6.1和9.5个百分点。同时,添加AR、BR和CR均能延缓丙二醛含量的升高,添加AR和BR还能使维生素C下降较慢,此外添加BR可使抗氧化酶活性保持较高水平。但与仅以RAE处理的对照组相比,AR、BR、CR处理对失重率、硬度影响较小,对可溶性固形物几乎无影响。综上,添加BR保鲜剂对采后椪柑具有良好的防腐保鲜效果。
The antifungal activities of petroleum ether extract(A),ethyl acetate extract(B)and n-butanol extract(C)of Rhizoma of Tupistra chinensis Baker against Penicillium digitatum,Aspergillus niger and Rhizopus stolonifer were investigated.The results showed that the antifungal activity of ethyl acetate extract was the strongest.On this basis,rosin resin(RAE)was used as coating agent,and the effects of preservatives(AR,BR and CR)with three kinds of Rhizoma extracts of T.chinensis(A,B and C)as antifungal agents on postharvest storage quality of ponkan were studied.The results showed that the petroleum ether extract and ethyl acetate extract in coating agent could effectively reduce the decay index of ponkan.After storage for 36 d,the decay indexes of ponkan treated by AR and BR coating were 10.6%and 7.2%,respectively,which were 6.1 and 9.5 percentage points lower than that of the blank control group(16.7%).At the same time,the addition of AR,BR and CR could delay the increase of malonaldehyde(MDA)content,the addition of AR and BR could delay the decrease of vitamin C and the addition of BR could keep the antioxidant enzyme activities at high level.However,AR,BR and CR had little effect on weight loss rate,hardness and soluble solids.Overall,the preservative BR had good preservative effect on postharvest ponkan.
