摘要

在这项研究中,从椰子壳、森贡木和玉米芯中生产并重新蒸馏出了液态烟雾。研究了液体烟雾(LS)和再蒸馏液体烟雾(r-LS)的颜色、pH 值和化学成分的变化。再蒸馏在约 100-105 °C 的温度下进行 3 小时。结果表明,三种生物质来源的再蒸馏烟液颜色比烟液浅。椰子壳、仙人木和玉米芯的 pH 值略有下降,分别从 3.63 降至 3.40、4.42 降至 3.39 和 3.53 降至 3.36。造成这一结果的原因是挥发性化合物的蒸发。同时,化学成分分析结果表明,除了酯类成分在椰壳和玉米芯中有所增加(分别从 2.98% 增加到 64.36%和从 2.98% 增加到 8.07%),其他主要成分在再蒸馏后都有所减少。

Physical and Chemical Components Characteristics of Liquid Smoke Redistillation from Different Biomass Sources
In this study, liquid smoke from coconut shells, sengon wood, and corn cobs has been produced and redistilled. The change of colour, pH value, and chemical components of liquid smoke (LS) and redistilled liquid smoke (r-LS) have been studied. Redistillation was carried out at about 100–105 °C for 3 hours. The results show that the colour of r-LS from the three biomass sources is lighter than LS. The pH values slightly decreased for coconut shell, sengon wood, and corn cobs, from 3.63 to 3.40, 4.42 to 3.39, and 3.53 to 3.36, respectively. This result is caused by the evaporation of volatile compounds. Meanwhile, the results of the analysis of the chemical components showed that all the main components of liquid smoke decreased after redistillation, except for the esters component, which increased in coconut shell and corn cobs, from 2.98% to 64.36% and 2.98% to 8.07%, respectively.
