Study On Volatile Components In Oats And Oats Flakes And Effects Of Oats Flakes In Patients With Hyperlipidemia

In order to study the flavor and volatile compounds of oats,oats kernels and oats flakes inShawan Xinjiang,Honghao Hebei,Saibao Neimeng,Ximai Guangxi,Jinwei Guangdong andQingmai Qinghai were extracted by headspace solid phase microextraction(HS-SPME),andanalyzed by gas chromatography-mass spectrometry(GC-MS).Then compared the changes ofthe volatile components in oats flakes by oats kernels and oats kernels,oats flakes in differentparts.Meanwhile,raw oats,dehulled oats,kiln and dried oats, rolled oats and oat flakes ofQinghai alpine oats were analysed,then study the changes of the volatile components duringprocessing. In addition, in order to understand the physiological of oat flakes, this paperselected alpine oats in Qinghai and naked oats in Xinjiang for clinical trials. Determiningthese indexes such as total cholesterol(TC),triglycerides(TG),high-density lipoproteincholesterol (HDLC), low density lipoprotein cholesterol (LDLC),blood glucose and weight, itaimed to analyze the effects on blood lipids,blood glucose and weight of different oat flakes.The main results were as follows:(1)The same volatile compoments of oats kernels in Shawan Xinjiang,Honghao Hebei, SaibaoNeimeng, Ximai Guangxi, Jinwei Guangdong and Qingmai Qinghai were Nonanal, Benzaldehyde, Hexanal,Dodecane, Tridecane, Tetradecane,1-Hexanol, Dibutyl phthalate,1,2-Benzenedicarboxylic acid,bis(2-methylpropyl)ester,2(3H)-Furanone,2-pentyl-Furan and Naphthalene.(2) The same volatile compoments of oats flakes in Shawan Xinjiang, Honghao Hebei, SaibaoNeimeng, Ximai Guangxi, Jinwei Guangdong and Qingmai Qinghai were Nonanal, Benzaldehyde,Undecane,Dodecane, Tridecane, Decane,1-Hexanol,2-pentyl-Furan, Naphthalene, Toluene, p-Xylene andEthylbenzene.(3)The same volatile compoments of alpine oats in five processing stages wereNonanal, Benzaldehyde, Dibutyl phthalate, Hexanoic acid, n-Hexadecanoic acid,2-pentyl-Furan andOxime-, methoxy-phenyl-.(4) Patients with hyperlipidemia was randomly assigned to consume40-50grams of alpine oats in Qinghai and naked oats in Xinjiang oatmeal per day for12weeks.Then we can know the two oats dietresulted in a significant reduction in body weight, GLU, TC and TG（P＜0.05),increase in HDLC（P＜0.05).
