Effects and formula optimization of Rosa roxbunghii pomace substrate on the yield and volatile flavor compounds of Lentinula edodes

Researchers discovered that using Rosa roxbunghii fruit waste as 30% of the growing medium for shiitake mushrooms produces better yields and more flavorful mushrooms compared to traditional sawdust-based methods. This sustainable approach solves a waste disposal problem while making mushrooms taste better, with higher levels of umami-contributing compounds. The findings could help local farmers reduce costs and improve mushroom quality while managing agricultural waste responsibly.
