Pyrolysis of cajuput () twigs and rice () husks to produce liquid smoke-containing fine chemicals for antibacterial agent application.

Pyrolysis of cajuput () twigs and rice () husks to produce liquid smoke and antibacterial activities of the liquid smoke fractions were investigated. The liquid smoke was produced by pyrolysis at 500 °C for 8 h and contained fine chemicals, such as acetic acid, carbonyl, cyclic ketones, and phenolic compounds with pH 2.1-2.
