采前处理对双孢蘑菇采后贮藏品质的影响
Acta Edulis Fungi(2023)
Abstract
探讨采前处理对采后双孢蘑菇(Agaricus bisporus)贮藏期间品质的影响.在采收前24 h,分别用0.1、1.0、10.0 mg·mL-1的香菇(Lentinula edodes)菌糠提取物(LR-UE)和水杨酸(salicylic acid,SA)溶液均匀喷施子实体表面,喷施量为250 mL·m-2,对照组喷施相同量的自来水;采收后分装,置于室温贮藏,贮藏0 d为采收后1 h内的子实体,以后每天取样,直至样品腐烂、褐变或产生异味为止,分别测定外观、白度、硬度、丙二醛(malondialdehyde,MDA)和总酚含量以及多酚氧化酶(polyphenol oxidase,PPO)和苯丙氨酸解氨酶(phenylalanine ammonia lyase,PAL)活性.结果表明:采前子实体表面喷施1.0 mg·mL-1 LR-UE和SA的双孢蘑菇在采后贮藏期间均能保持较好的外观、较高的白度和较好的硬度;与对照组相比,采前喷施LR-UE和SA均能有效降低MDA和总酚含量,抑制PPO和PAL活性,且总酚含量与PAL活性变化趋势一致.
