Flammulina velutipesis highly valued and widely consumed because of its nutritional and functional benefits, and its global demand is steadily increasing. However, rapid quality deterioration and short shelf life create an urgent need for effective preservation and advanced quality assessment of Flammulina velutipes. The aim of this review was to identify methods that reduce postharvest quality loss, extend shelf life, and optimize storage and distribution practices for Flammulina velutipes. Chemical treatments (including antioxidants, 1-methylcyclopropene, and edible coatings), low-temperature plasma, and innovative nanocomposite-based packaging have been effective in maintaining Flammulina velutipesquality after harvest. Nevertheless, further discussions on the economic feasibility, safety, and sustainability of these technologies are essential for their practical and industrial applications in Flammulina velutipespreservation.
