Identification of Odorous Compounds in Fresh and Rotten Swine Manure

摘要: In order to elucidate the nature of malodor from piggery wastes, volatile compounds in fresh faeces, urine, rotten and mixtures faeces urine were isolated by freeze vacuum distillation continuous extraction identified gas chromatography-mass spectrometry. Many alcohols detected not but faeces. Various fatty acids determined at high concentrations all samples, their abundance was different urine. Large amounts phenols came Aromatic carboxylic only decreased rapidly during digestion. Indole 3-methylindole which present showed a reverse change concentration
