Benefits of technology

This patented process involves crushing or grinding vegetables with certain techniques like heat treatment for better release of volatile compounds during processing. By applying this technique, it becomes possible to break down large pieces into smaller parts that contain more useful chemicals than traditional methods such as steam explosion or organosolv processes. Additionally, these new technologies have been developed specifically designed to improve both taste perception and production yield while reducing damage caused by excessive temperatures used when making cigarettes containing specific types of essential oils. Overall, this innovative approach allows us to efficiently produce valuable products without causing harmful side reactions on plants' cells.

Problems solved by technology

Lignum coffee (L.) Coffee) belongs to an annual plant that contains over 20% resin gums called guanilla bark). It's commonly found throughout North America but it may have other uses such as traditional use in cookery like roasting rice and breadmaking. Its main active component being luteolin is known from Lauricum acid BMPRINESA® which helps improve blood flow and reduce swelling during exercise activities.

Abstract

The invention provides a method for preparing a liquorice root extract for tobaccos. Liquorice root slices are subjected to high-pressure puffing, and are then subjected to supercritical CO2 extraction and molecular distillation to obtain the liquorice root extract for tobaccos. The method provided by the invention has the advantages that the extraction yield of active ingredients in the liquorice roots can be improved; the glycyrrhizic acid content in the obtained liquorice root extract is high; when the liquorice root extract is applied into a cigarette, the effects of enriching the cigarette flavor, sweetening and moisturizing the smoke gas and correcting the smoking taste can be achieved.
