我所从1986年开始在室内培植金针菇,并测定了不同品种金针菇的几种营养成分含量。现将测定方法和结果简报如下:实验方法(一)制备样品将适量鲜金针菇的菌盖、菌柄分开,放入40～50℃鼓风干燥箱中烘约24小时后置空气中与空气湿度相平衡24小时以上,即为风干样品。(二)水分测定采用105℃干燥法。称取风干试样约5,000克,放入105℃干燥箱中烘至恒重。(三)灰分测定称取已测水分的干样品2～5克,在电炉上烧至无烟后,移入550～660℃高温炉中灰化至灰白色(约2～3小时),取出置干燥器冷却
Since 1986, I have cultivated Flammulina velutipes indoors and determined the contents of several nutrients in different varieties of Flammulina velutipes. Now the determination of the method and results are as follows: Experimental methods (a) Preparation of the sample amount of fresh Flammulina vetiver cover, stipe separate, into the oven at 40 ~ 50 ℃ Bake for about 24 hours after the setting of air and air humidity Phase equilibrium for more than 24 hours, that is, air-dried samples. (B) Determination of moisture using 105 ℃ drying method. Weigh about air-dried sample of about 5,000 grams, into the oven at 105 ℃ drying to constant weight. (C) Determination of ash Weigh 2 to 5 grams of dry sample measured moisture, after burning on a hot stove to smokeless, moved to 550 ~ 660 ℃ high temperature furnace ashed to gray (about 2 to 3 hours), remove the dry Cool the device
