摘要:以不同干燥方式得到西藏金耳干品为研究对象,对真空冷冻干燥(编号LDJE )、热风烘干(编
号RFJE )得到的
金耳干品的粗蛋白、粗脂肪、氨基酸、挥发性成分进行比较分析。结果表明,LDJE 粗蛋白含量略低于RFJE ,LDJE 的粗
脂肪含量比RFJE 含量高,RFJE 和LDJE 中必需氨基酸的总量占整个金耳的39.67%~41.76%,两种干燥方式金耳的必需氨基酸质量分数均超过FAO/WHO 模式谱的参考值。2种干燥方式所得到金耳2个样品通过气相色谱-质谱联用(gas chromatography-mass spectrometer ,GC-MS )共检测到107种化合物,其中真空干燥81种,特有化合物16种;热风干燥91种,特有化合物26种。鼎的读音

Abstract :Tremella aurantialba dried products were obtained from different drying methods ,the cr
ude protein ,crude fat ,amino acid and volatile components of Tremella aurantialba dried products obtained by vacuum freeze drying (numbered LDJE )and hot air drying (numbered RFJE )were compared and analyzed.The results showed that the crude protein content of LDJE was slightly lower than that of RFJE ,and the crude fat content of LDJE was slightly higher than RFJE.The total amount of esntial amino acids in RFJE and LDJE accounts for 39.67%-41.76%of the whole Tremella aurantialba .The amino acid mass fractions all exceeded the reference values of the FAO/WHO model spectrum.A total of 107compounds were detected by gas chromatography-mass spectrometer (GC-MS )in two samples of Tremella aurantialba obtained by two drying methods ,of which 81were vacuum dried and 16were peculiar compounds ;91were dried by hot air and 26were peculiar compounds.Key words :Tremella aurantialba ;nutrition evaluation ;gas chromatography -mass spectrometer (GC -MS );
