Researchers at 成人VR视频 have discovered that moderate ultraviolet (UV) light exposure is best when the technique is used to聽enhance vitamin D鈧� in edible mushrooms. Excessive exposure聽leads to nutrient degradation or a plateau effect, they found. The paper also聽provides聽quantitative guidance.聽

The聽researchers鈥櫬爓ork聽supports聽efforts to address vitamin D deficiency, which affects between 30聽and聽50 per cent of the world鈥檚 population, as well as enhance the nutritional value of mushrooms more broadly.聽

鈥淲hile many studies demonstrated that UV could improve mushroom nutrition, there hasn鈥檛 been a standardized or optimized set of conditions that researchers and industry can reliably follow,鈥� said聽Val茅rie Orsat,聽Professor of聽Bioresource Engineering聽and study co-author.聽聽

鈥淥ur findings highlight a clear gap: the need for species-specific and unified UV treatment guidelines. These should define safe and effective ranges that consistently enhance nutrients like vitamin D鈧� without compromising quality attributes such as texture,聽colour聽or overall consumer appeal,鈥澛爏he said.聽

Regulatory bodies like the聽U.K.聽Food Standards Agency聽and Food聽Standards聽Scotland have聽confirmed that UV-treated mushroom products are safe for consumption. Human studies have聽already聽shown that consuming UV-treated mushrooms can increase vitamin D levels, confirming their nutritional benefit.聽

Meta-analysis fills in the gaps聽

Previous聽research on聽this topic聽has shown significant variability聽in factors such as UV intensities, exposure times and treatment setups used across studies, often leading to inconsistent outcomes.聽聽

In this study, the researchers聽conducted聽a meta-analysis聽of 22 studies聽published between聽2020聽and聽2025. They聽gathered聽and analyzed聽key variables such as UV intensity, exposure time, dose, mushroom form (sliced聽or聽whole) and resulting vitamin D鈧� levels, and聽applied聽a聽response surface analysis聽鈥撀燼 statistical modelling technique聽鈥撀爐o map how these variables interacted.聽聽

This approach allowed them聽to聽identify聽the safe and聽optimal聽treatment zone,聽the聽conditions that maximized聽vitamin D鈧� while聽maintaining聽mushroom quality,聽for each species.聽

鈥淚n short, we moved beyond individual studies to build a data-driven, unified picture of what works best,鈥澛燨rsat聽said.聽

Blue聽and聽green light to be considered聽

Soon,聽the team will聽begin聽exploring聽how聽different types聽of light,聽such as blue and green light,聽can be used聽individually or in combination with UV to enhance a broader range of desirable compounds聽found in mushrooms.聽

鈥淔uture research is shifting toward a more integrated approach,聽using strategically programmed聽light treatment聽from cultivation through post-harvest and storage,鈥� said聽, study co-author and聽a聽成人VR视频 PhD student. 鈥淭he idea is to develop synergistic light treatments that not only boost vitamin D鈧�, but also improve other nutrients, bioactive compounds and overall quality through storage and retail display.鈥澛�

鈥淯ltimately, this could lead to standardized, scalable light-based technologies for the mushroom industry, delivering safer, more nutritious and functionally enhanced products across the entire supply chain,鈥澛爃e said.聽
