外源褪黑素处理对红托竹荪鲜品贮藏品质的影响

Effect of Exogenous Melatonin Treatments on the Storage Quality of Dictyophora rubrovolvata

  • 摘要: 本研究采用红托竹荪鲜品作为材料,旨在探讨不同浓度外源褪黑素处理的红托竹荪鲜品贮藏期间品质变化规律。将红托竹荪鲜品分为4个处理(CK处理、50 μL/L褪黑素处理、100 μL/L褪黑素处理及150 μL/L褪黑素处理),贮藏于(1±0.5)℃环境中。每3 d测定不同褪黑素处理对红托竹荪鲜品贮藏期间感官评价、腐烂率、呼吸强度、丙二醛含量、褐变指数、能量水平、超氧阴离子产生速率、H2O2含量及抗氧化酶的影响。结果表明:贮藏12 d时,CK、Y1、Y2和Y3处理组感官评价综合得分为2.68、6.48、8.52及7.28,腐烂率分别为30.48%、19.29%、5.48%及6.99%,此外,褪黑素处理还能够显著(P<0.05)抑制呼吸强度、丙二醛含量、褐变指数、超氧阴离子产生速率和H2O2含量的上升,维持能量水平及抗氧化酶系统的活性。由此可知,外源褪黑素处理可减缓贮藏期间红托竹荪鲜品的衰老过程,更好得维持其商品性,其中100 μL/L褪黑素处理效果最佳。

     

    Abstract: In order to explore effect of exogenous melatonin treatments on storage quality of the fresh Dictyophora rubrovolvata, using fresh Dictyophora rubrovolvata as test material, samples were devided into four treatments (CK, 50 μL/L melatonin, 100 μL/L melatonin and 150 μL/L melatonin). The storage temperature was (1±0.5) ℃. Every 3 d, the sensory quality evaluation, rot ratio, respiration rate, malondialdehyde content (MDA), browning degree index, energy metabolism, O2·generation rate, mass H2O2 fraction and antioxidant capacity were detected. The results showed that the sensory quality of CK, Y1, Y2 and Y3 at 12 d were 2.68, 6.48, 8.52 and 7.28 while rot ratio were 30.48%, 19.29%, 5.48% and 6.99%. Beside that, all the exogenous melatonin treatments could significantly (P<0.05) inhibit the respiration rate, MDA content, browning degree index, O2· generation rate and mass H2O2 fraction of the fresh Dictyophora rubrovolvata increased, and could maintain the energy metabolism and the antioxidant capacity. These results suggested that exogenous melatonin treatment could inhibit the senescence process and maintain the commodity of the fresh Dictyophora rubrovolvata. Among them, exogenous melatonin at 100 μL/L had the best preservation effect on the fresh Dictyophora rubrovolvata.
