Umami Light Switch

Umami Light Switch

Shiitake mushroom (Lentinula edodes) treated with blue light kept higher flavor-supporting sugars during spore discharge, with mannitol up 11.1%, fructose up 12.0%, and soluble sugars up 71.2% versus untreated controls. Blue light also activated energy and umami metabolism enzymes while shifting photoreceptor gene expression by 1.13–2.93×. The result is a simple postharvest tool for protecting shiitake’s savory flavor as the mushroom starts to age.
