摘要： A method of producing a liquid tobacco extract is provided, the method including the steps of: preparing a tobacco material; heating the tobacco material at an extraction temperature of between 100 degrees Celsius and 160 degrees Celsius for at least 15 minutes, the tobacco material being heated directly; collecting volatile compounds released from the tobacco material during the heating step; and forming a liquid tobacco extract including the collected volatile compounds, the tobacco material being microwave heated during at least one step of the method. A liquid tobacco extract produced by the method is also provided.

摘要： A method of producing a liquid tobacco extract is provided, the method including the steps of: preparing a tobacco material; heating the tobacco material in an extraction chamber at an extraction temperature of between 120 degrees Celsius and 160 degrees Celsius for at least 90 minutes; spraying atomised water into the extraction chamber during the heating step; collecting volatile compounds released from the tobacco material during the heating step; and forming a liquid tobacco extract comprising the collected volatile compounds. A liquid tobacco extract produced by the method is also provided.

摘要： A method of producing a liquid tobacco extract, the method including the steps of: preparing a tobacco material; applying an alkaline solution to the tobacco material to produce an alkalised tobacco material; heating the alkalised tobacco material at an extraction temperature of between 100 degrees Celsius and 160 degrees Celsius for at least 30 minutes, the alkalised tobacco material being heated in a flow of inert gas or in a flow of a combination of an inert gas with water or steam, and a water content of the alkalised tobacco material, prior to the heating step, being between 10 percent by weight and 20 percent by weight; condensing volatile compounds released from the alkalised tobacco material during the heating step and collecting condensate of the volatile compounds; and forming a liquid tobacco extract comprising the condensate of the volatile compounds.
