The result showed that ethyl acetate increased 342% after a 5 cycle treatment. In the HPH treatment (30¡V90 MPa under 10¡V25 ¢XC with 1¡V7 cycles) of commercial sorghum spirit, the test shows that ethyl acetate and ethyl lactate were 2316 and 1586 ppm, respectively, while no obvious changes were observed in methanol, fusel oil and total acidity, and only a slight decline in ethanol. In addition, the results also show that HPH treatment can reduce the methanol content and produce other aroma compounds such as methyl acetate. Sensory evaluation also revealed improvement effects on flavor, smoothness, aftertaste and acceptability of the artificial aging technology on the production of spirits. ? 2019 Elsevier LtdAgingAromaHigh-pressure homogenizationSensory evaluationSpiritsjournal article10.1016/j.lwt.2019.01.0532-s2.0-85061643989https://www.scopus.com/inward/record.uri?eid=2-s2.0-85061643989&doi=10.1016%2fj.lwt.2019.01.053&partnerID=40&md5=0810a2a98099e32bd8e8f841e2ac68cd
