Analysis of nutrient composition of several common wild edible fungi in three provinces of north China

In order to understand the nutritional value of wild edible fungi,several wild edible fungi of three provinces in northern China(the Inner Mongolia Autonomous Region,Liaoning Province,Jilin Province)were used as materials in the test,compared with Letinous edodes and Pleurotus ostreatus which were common on the market,to find the nutritional differences. The results showed that ash content in the 11 wild edible fungi species were much higher than artificial cultivation. In the comprehensive evaluation of protein content and amino acid,Pleurotus ostreatus(CK1)and Letinous edodes(CK2)were higher than JI-2 and JI-3,while they were less than other areas of edible fungi. In the polysaccharide and crude fiber,Pleurotus ostreatus(CK1)and Letinous edodes(CK2)were at the medium level. In general,although there was a big difference of nutritional components in these wild edible fungi,developing the wild edible fungi had definitive value.
