Abstract

The supercritical carbon dioxide (SCO2) extraction of biomass for aroma components has the characteristics of high extraction efficiency, low pollution, and easy separation of the extraction products. Combined with appropriate raw material pretreatment methods, the physical and chemical properties of the raw materials can be changed to further optimize the extraction process. However, the effects of different pretreatment methods on the yield and composition of biomass SCO2 extraction products are still unclear. Therefore, this research used tobacco waste residue (TWR) as raw material to explore the effects of different pretreatment methods (grinding, freeze-drying, torrefaction and acid-washing) on the composition of its SCO2 extraction products. Research shows that compared with untreated tobacco waste residue, grinding effectively increases the yield of SCO2 extraction products of TWR and the extraction product yield increased over 30%; the freeze-drying and torrefaction processes caused a large loss of the extractables, leading to a reduction in extraction efficiency, a decrease in the content of the pyridines in the extraction product, and an increase in the relative content of the hydrocarbons. Acid washing effectively changed the relative content of the hydrocarbons and the pyridines in the extract while having a low impact on the yield of the extraction product, directionally increasing the content of hydrocarbon aroma components.
