Abstract

The shelf-life of fresh mushrooms is limited to 1-3 days at ambient conditions and antioxidant characters are reduced and acquire a brown colour during post-harvest storage. Therefore, the present study was conducted to investigate the effect of some postharvest exogenous edible coating treatments of immersed in six different solutions for 5 min of calcium chloride (2%, 4%), chitosan (1%, 2%), CMC (1%, 2%) and control (distilled water) on reducing the browning, microbial load and maintaining quality during storage for 15 days at 4 ± 1 °C and 95% RH, during two successive seasons of 2021 and 2022 in 4th and 6th of January in the first and second seasons respectively. The obtained results revealed that dipping mushroom plants in a solution of chitosan 2% or calcium chloride 4% was the best treatment for reducing weight loss, while chitosan 2% for 5 min was the most effective treatment in reducing browning, PPO activity, total phenolic, flavonoids contents and inhibiting microbial counts for 12 days at 4 ± 1 °C and 95% RH.

采后外源食用包衣处理对鲜蘑菇褐变抑制及品质保持的影响

新鲜蘑菇在环境条件下的保质期限制在1-3天，在收获后的储存过程中，抗氧化特性降低并呈现棕色。因此，本研究旨在研究一些采后外源性可食用包衣处理在4±1°C和95%相对湿度下储存15天的过程中，在氯化钙（2%，4%）、壳聚糖（1%，2%）、CMC（1%，2%）和对照（蒸馏水）的六种不同溶液中浸泡5分钟，对降低褐变、微生物负荷和保持品质的影响，在2021年和2022年的连续两个季节，分别在第一季和第二季的1月4日和6日。结果表明，在4±1°C和95%RH条件下，将蘑菇植物浸泡在2%的壳聚糖或4%的氯化钙溶液中是减肥的最佳处理，而2%的壳多糖浸泡5min对降低褐变、PPO活性、总酚、黄酮含量和抑制微生物计数最为有效。

期刊介绍： Notulae Botanicae Horti Agrobotanici Cluj-Napoca is a peer-reviewed biannual journal aimed at disseminating significant research and original papers, critical reviews and short reviews. The subjects refer on plant biodiversity, genetics and plant breeding, development of new methodologies that can be of interest to a wide audience of plant scientists in all areas of plant biology, agriculture, horticulture and forestry. The journal encourages authors to frame their research questions and discuss their results in terms of the major questions of plant sciences, thereby maximizing the impact and value of their research, and thus in favor of spreading their studies outcome. The papers must be of potential interest to a significant number of scientists and, if specific to a local situation, must be relevant to a wide body of knowledge in life sciences. Articles should make a significant contribution to the advancement of knowledge or toward a better understanding of existing biological and agricultural concepts. An international Editorial Board advises the journal. The total content of the journal may be used for educational, non-profit purposes without regard to copyright. The distribution of the material is encouraged with the condition that the authors and the source (Notulae Botanicae Horti Agrobotanici Cluj-Napoca or JCR abbrev. title Not Bot Horti Agrobo) are mentioned.
