Abstract

|
|
The new cultivar Lentinula edodes, which is named ‘Lentinula edodes GNA01’, was bred by mating strains isolated from ‘L26’ and ‘Kyoungwon9015’ obtained from Sammyungjin Research Institute, Fujian, China. L. edodes GNA01 does not have stipes like L. edodes, although it generally has a similar spherical shape. Moisture and crude protein contents of L. edodes GNA01 were lower than those of L. edodes. Meanwhile, L. edodes GNA01 contained higher levels of crude ash, crude lipid, crude fiber, and carbohydrates than L. edodes. The β-carotene content (19.05 μg/100 g) of L. edodes GNA01 was about three times higher than that of L. edodes. In addition, vitamin D content (118.53 μg/100 g) of L. edodes GNA01 was more than twice that of L. edodes. L. edodes GNA01 was a good source of mineral elements, with K and Mg contents of 2,277.50 mg/100 g and 203.15 mg/100 g, respectively. The major fatty acids of L. edodes GNA01 were C16:0 and C18:2, and L. edodes GNA01 had the highest linoleic acid (C18:2) content of 1,087.66 mg/100 g. Total phenol content of L. edodes GNA01 was 12.52 mg GAE/g, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities and ferric reducing antioxidant power (FRAP) values of L. edodes GNA01 were lower than those of L. edodes at all concentrations. However, DPPH radical scavenging activities and FRAP values of L. edodes GNA01 were above 80% and 0.9 at a concentration of 10 mg/mL, respectively.
