中文摘要:
      目的 研究低温贮藏环境下不同电场强度的低压静电场(Low Voltage Electrostatic Field,LVEF)对双孢蘑菇采后贮藏品质的影响。方法 随机将双孢蘑菇分为不同电压(100、200、300 V)的LVEF处理组和无任何处理的对照组,并于温度为4 ℃的环境下贮藏8 d。结果 LVEF处理能抑制质量损失率和丙二醛含量的上升,减缓软化速度,提高类黄酮和抗坏血酸等抗氧化物质的含量,抑制多酚氧化酶和过氧化物酶活性,从而延缓双孢蘑菇褐变。电压为200 V与300 V的LVEF处理保鲜效果较好,但300 V的LVEF处理抑制细胞膜的氧化损伤和酶活性弱于200 V的LVEF处理。贮藏8 d后,与对照组相比,200 V的LVEF处理的双孢蘑菇L*值增加了4.2%,BI值减少了23.1%,质量损失率减少了37.4%,硬度增加了10.4%。结论 LVEF处理能有效延缓双孢蘑菇采后贮藏品质的变化,且电压为200 V的LVEF处理双孢蘑菇保鲜效果更好。
英文摘要:
      The work aims to investigate the effects of low voltage electrostatic field (LVEF) with different electric field strengths on the postharvest storage quality of Agaricus bisporus during cold storage. Agaricus bisporus were randomly divided into LVEF groups with different voltages (100 V, 200 V, and 300 V) and a control group without any treatment, and stored at 4 °C for 8 days. The results showed that LVEF treatment inhibited the increase in weight loss rate and malondialdehyde content, slowed down the softening rate, increased the content of antioxidants such as flavonoids and ascorbic acid, and inhibited the activities of polyphenol oxidase and peroxidase, thus delaying the browning of Agaricus bisporus. LVEF treatments at voltages of 200 V and 300 V were more effective in preserving Agaricus bisporus, but the inhibition of oxidative damage to cell membranes and enzyme activities in the LVEF treatment at 300 V was weaker than that in the LVEF treatment at 200 V. After 8 days of storage, compared with the control group, the L value of Agaricus bisporus treated with LVEF at 200 V increased by 4.2%, the BI value decreased by 23.1%, the weight loss rate decreased by 37.4%, and the hardness increased by 10.4%. In conclusion, LVEF treatment is effective in delaying the changes in postharvest storage quality of Agaricus bisporus, and LVEF treatment at a voltage of 200 V is a promising technique for preserving Agaricus bisporus during cold storage.
