“…7, the chitinase activity of mushrooms revealed a general declining tendency, while the ⊎-1, 3-glucanase activity of samples revealed a rising trend during storage time. Changes in the activities of the two enzymes during storage were compatible with study reported by Guo et al 18 More importantly, both chitinase and ⊎-1, -3-glucanase showed higher activity in UV-C-treated mushrooms during storage, with 24.33% and 25.14% higher activity, respectively, in comparison with the control on day 21.…”

BACKGROUNDAgaricus bisporus (A. bisporus) with completely white appearance are popular with consumers. However, A. bisporus are easily senescence and spoilt, which results in browning and oxidative tissue damage with limited shelf life. This study investigated the effects of shortwave ultraviolet (UV‐C, 1.0 kJ m−2) irradiation on quality features, enzymatic browning, defense properties of A. bisporus stored at 4 °C for 21 d.RESULTSAfter storage, UV‐C irradiated A. bisporus had increased quality on sensory, color, hardness, exhibited higher content in total phenolic, brown melanin precursors, including γ‐glutaminyl‐4‐hydroxybenzene (GHB), γ‐glutaminyl‐3,4‐dihydroxybenzene (GDHB) and tyrosine content, lower accumulation of malondiadehyde (MDA), hydrogen peroxide (H2O2), superoxide radical (O2•¯) and maintained membrane integrity in comparison to control samples. Besides, A. bisporus treated by UV‐C showed lower degree of browning and higher level of self‐defense capacity which may be ascribed to the enhancement in activities of superoxide dismutase (SOD), catalase (CAT), phenylalanine ammonia lyase (PAL), Chitinase (CHT), β‐1, 3 glucanase activity (GLU) and inhibiting the activities of polyphenol oxidase (PPO) during the storage.CONCLUSIONThese results indicated that the higher self‐defense capacity with UV‐C treatment might be the mechanism associated with the delay of senescence in Agaricus bisporus. Therefore, the UV‐C treatment is suggested as a potential practical application in mushrooms.This article is protected by copyright. All rights reserved.

“…Meanwhile, the softening essence of F. velutiper is characterized by structural changes in the colloidal layer in the cell, followed by separation of the cell and degradation of the cell wall material. The cell wall of the mushroom is mainly composed of glucan, chitin and protein 26 . Fruit softening is closely related to the activity of the cell wall degrading enzymes, particularly phenylalanine deaminase (PAL), cinnamyl alcohol dehydrogenase (CAD), cellulase (Cx), pectin methyl esterase (PME) and polygalacturonase (PG) 40,41 .…”

“…Despite the abundance of nutrients and high physiological activity after harvesting, the vigorous respiratory metabolism increased the degree of senescence and water content, and high susceptibility to environmental stress (opening and stalk elongation) and microbial infestation (including pathogenic bacteria and spoilage bacteria) lead to the decay of F. velutiper . As such, its shelf life is short (generally 3–5 days), severely hindering the development of the golden mushroom industry 14,22‐26 …”

Recent advances in quality preservation of postharvest golden needle mushroom (Flammulina velutiper)

The golden needle mushroom (Flammulina velutiper) is one of the most productive mushrooms in the world. However, F. velutiper experiences continuous quality degradation in terms of changes in color and textural characteristics, loss of moisture, nutrition and flavor, and increased microbial populations due to its high respiratory activity during the postharvest phase. Postharvest preservation techniques, including physical, chemical and biological methods, play a vital role in maintaining postharvest quality and extending the shelf life of mushrooms. Therefore, in this study, the decay process of F. velutiper and the factors affecting its quality were comprehensively reviewed. Additionally, the preservation methods (e.g., low‐temperature storage, packaging, plasma treatment, antimicrobial cleaning and 1‐methylcyclopropene treatment) for F. velutiper used for the last 5 years were compared to provide an outlook on future research directions. Overall, this review aims to provide a reference for developing novel, green and safe preservation techniques for F. velutiper. © 2023 Society of Chemical Industry.

Growing concerns over the human health and environmental impacts of conventional fungicides, coupled with the escalating challenge of microbial resistance, have fueled the search for sustainable biocontrol strategies against plant pathogens. This study reports, for the first time, the green synthesis and characterization of a novel, eco‐friendly nanomaterial, designated Pleurotus eryngii‐Lecithin‐Chitosan Nanomaterial (PEELCN), derived from P. eryngii extract (PEE), lecithin (L), and chitosan (C). The structural attributes of PEELCN were elucidated using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), X‐ray Diffraction (XRD), and zeta potential measurements, confirming the successful formation of a stable and uniform nanostructure. The antifungal activity of PEELCN, and PEE, was assessed against five economically important phytopathogenic fungi: Neoscytalidium dimidiatum, Alternaria alternata, Verticillium dahliae, Bipolaris sorokiniana, and Fusarium oxysporum. Both PEE and PEELCN exhibited significant inhibitory effects on the mycelial growth of V. dahliae, B. sorokiniana, and N. dimidiatum, with varying degrees of efficacy. The differential antifungal activity suggests a species‐specific mode of action. The findings highlight the promising potential of PEELCN as a sustainable, biocompatible, and cost‐effective nanofungicide for the management of plant diseases, with the potential for development into a commercially viable biofungicide for sustainable agriculture.
