Effect of compost formulation and postharvest management on quality parameters of button mushroom

Abstract

Purpose The main objective of the present study was to evaluate the effects of compost formulation made from agricultural by-products and thermal treatment of fresh mushrooms on the postharvest quality parameters. Methods Quail manure was evaluated as an alternative ingredient to the broadly used chicken manure for compost preparation. In addition, the treatment of fresh mushrooms by hot water to extend shelf-life was tested. Quality parameters including color (browning due to microbial activity), cap opening and the weight loss (senescence) were evaluated. Results The nature of the manure employed as base material in the substrate can affect the postharvest browning ratio of mushroom. However, no significant differences in Δb value, weight loss or cap opening were noticed between two different substrates during storage of harvested mushrooms. The cap opening ratio was further retarded while applying thermal treatment to the mushrooms at 55 °C. Conclusions The use of chicken manure as base material to prepare mushroom substrate reduces mushroom browning during storage compared to quail manure, although mushrooms from quail compost are whiter at picking. Postharvest treatment at 45 °C for 4 min was the best to minimize the weight loss.

Effect of different cooking methods on selected quality criteria and polycyclic aromatic hydrocarbon content of cultivated mushrooms (Agaricus bisporus)

“…Ranjbar et al . (2019) also reported that button mushrooms harvested from quail manure compost exhibited a higher L* value, indicating a whiter appearance, compared to those harvested from chicken manure compost. Additionally, compost used for mushroom production can also affect the post‐harvesting changes.…”

“…Ranjbar et al . (2019) noted that mushrooms cultivated on chicken manure maintained their whiteness for longer storage duration than those grown on quail manure.…”

“…In this context, El Sebaaly et al (2019) reported significant variations in water content, protein, carbohydrates, crude fibres, fat, ash, and mineral composition, including Na, Mg, K, Ca, and Fe, in button mushrooms due to the different type of substrate used for mushroom production. Ranjbar et al (2019) also reported that button mushrooms harvested from quail manure compost exhibited a higher L* value, indicating a whiter appearance, compared to those harvested from chicken manure compost. Additionally, compost used for mushroom production can also affect the post-harvesting changes.…”

Mycoselectivity of Mushroom Compost and Surfaces, Disinfected with Gas Chlorine Dioxide

“…Microorganisms play an important role in high-yielding production of A. bisporus. Compost preparation is a critical step in the cultivation process, where the biochemical transformations that take place during composting, provide the nutrients that determine mushroom growth [7][8][9]. Viera and Pecchia (2018) and many other authors [11,12] described the influence of pasteurization conditions of compost, and additives or external microorganisms on the composition of the fungal growth and the fruiting environment.…”
