不同栽培方式的香菇及黑木耳品质分析与比较OA

This study aimed to clarify the quality differences of representative edible fungi in Kang County,Gansu Province,i.e.,Lentinula edodes and Auricularia auricula,under different cultivation methods,so as to provide references for selecting mainstream cultivation methods and optimizing substitute substrates for the edible fungus industry in Kang County.Using L.edodes and A.auricula cultivated through two primary methods,substrate culture and log culture,in Kang County,Gansu Province as experimental materials,sensory parameters such as fruit body size and texture characteristics,as well as differences in nutritional content including fat,protein,crude polysaccharides,and mineral element levels were determined and compared in this study.Results showed that the quality of L.edodes cultivated with substrate culture was superior to that cultivated on logs,characterized by regular,uniform,and aesthetically pleasing fruit bodies.Contents of major nutrients,including protein,dietary fiber,and crude polysaccharide,as well as mineral elements such as calcium,potassium,and phosphorus,were all higher than those of log-cultivated L.edodes.Specifically,the crude polysaccharide content reached 22.6 g/kg,representing a significant increase of 85.25%compared with that in log cultivation,contents of calcium and phosphorus were 20.1 mg/kg and 1.68 g/kg,respectively,increasing significantly by 91.43%and 52.73%,respectively.The overall quality of A.auricula using substrate culture was also superior to that of log-cultivated A.auricula,as reflected by regular and uniform fruit body shape,as well as better commercial quality and palatability indicated by texture characteristics.Contents of major nutrients,including fat,protein,crude polysaccharide,melanin,total amino acids,and mineral elements such as calcium and phosphorus,were all higher to varying degrees than those of log-cultivated A.auricula.Among them,contents of fat,protein,and amino acid were 2.0,14.9,and 10.1 g/kg,respectively,representing significant increases of 100%,77.38%,and 741.67%compared with those in log-cultivated A.auricula,respectively.In conclusion,substrate culture is considered more suitable for the development of the L.edodes and A.auricula edible fungus industry in Kang County,Gansu Province.
