New preservation and detection technologies for edible mushrooms: A review

Abstract

Edible mushrooms are nutritious, tasty, and have medicinal value, which makes them very popular. Fresh mushrooms have a high water content and a crisp texture. They demonstrate strong metabolic activity after harvesting. However, they are prone to textural changes, microbial infestation, and nutritional and flavor loss, and they therefore require appropriate post‐harvest processing and preservation. Important factors affecting safety and quality during their processing and storage include their quality, source, microbial contamination, physical damage, and chemical residues. Thus, these aspects should be tested carefully to ensure safety. In recent years, many new techniques have been used to preserve mushrooms, including electrofluidic drying and cold plasma treatment, as well as new packaging and coating technologies. In terms of detection, many new detection techniques, such as nuclear magnetic resonance (NMR), imaging technology, and spectroscopy can be used as rapid and effective means of detection. This paper reviews the new technological methods for processing and detecting the quality of mainstream edible mushrooms. It mainly introduces their working principles and application, and highlights the future direction of preservation, processing, and quality detection technologies for edible mushrooms. Adopting appropriate post‐harvest processing and preservation techniques can maintain the organoleptic properties, nutrition, and flavor of mushrooms effectively. The use of rapid, accurate, and non‐destructive testing methods can provide a strong assurance of food safety. At present, these new processing, preservation and testing methods have achieved good results but at the same time there are certain shortcomings. So it is recommended that they also be continuously researched and improved, for example through the use of new technologies and combinations of different technologies. © 2023 Society of Chemical Industry.

Mechanisms of Action and Preservation Effects of Packaging Systems for Mushrooms: Novel Approaches to Preserve Irish Edible Mushrooms

“…Agaricus bisporus, Lentinus edodes, Pleurotus ostreatus, Flammulina velutipes, and Pleurotus eryngii are common edible mushroom species found in mainstream foods [1]. Because of its great flavor and nutritional value, Agaricus bisporus, commonly referred to as "white button mushroom", is the most widely grown and consumed edible mushroom in the world, making up 30% of all mushroom production [2].…”

“…These effects involve physicochemical quality degradation, including cap opening, loss of essential phenolic compounds, proteins, and vitamins, water loss, cell membrane deterioration, loss of firmness, and increased microbial activity in the process of storage and transportation [20,21], in turn leading to loss of nutritional value, flavor, market acceptability value, and shelf life. Recent findings have reported a wide range of preservation techniques for fresh mushrooms, including irradiation [22], ultrasonication [22], pulsed eclectic field treatment [23,24], [25,26], 1-methylcyclopropene treatment [27], modified atmosphere packaging, active packaging, edible coatings and nanopackaging [1,15,[28][29][30][31], and biodegradable packaging made from materials such as dextran/chitosan [32].…”

Recent advances and role of melatonin in post-harvest quality preservation of shiitake (Lentinula edodes)

“…Numerous preservation techniques have the potential to minimize the deterioration of post-harvest quality and extend mushroom shelf life. Traditional methods like drying and cooling, categorized as thermal processes, are commonly used to slow down mushroom quality degradation by regulating storage temperature and water activity ( 10 ). Modified atmosphere packaging (MAP) is an alternative method that preserves fresh mushrooms’ postharvest quality ( 11 ).…”

The Effects of Preharvest Silicon Treatment and Passive MAP on Quality and Shelf Life of White Button Mushrooms in Thermoformed Recycled PET Packaging System

“…Various packaging types are widely used to extend the shelf life of mushrooms, including nano-packaging and polysaccharide nanoparticle preservation, modified atmosphere packaging, active packaging, edible film packaging, and nanocomposite packaging [3,[10][11][12][13][14]. Of these, modified atmosphere packaging (MAP) is a safe, environmentally friendly, simple and cost-effective packaging technique for maintaining the postharvest quality of fresh edible mushrooms.…”
