Preserving Shiitake Mushrooms

Preserving Shiitake Mushrooms

X-rays can be used to extend the shelf life of shiitake mushrooms (Lentinus edodes). A 0.5 kGy dose effectively maintained sensory qualities, including flavor and texture, for up to 35 days. The treatment reduced microbial growth, minimized nutrient loss, and preserved key compounds like soluble proteins and phenols. Higher doses (1.0–1.5 kGy) altered the mushrooms’ odor profile, but the 0.5 kGy dose proved ideal for retaining freshness and nutritional value.
