technical field

The invention belongs to the field of spices for tobacco, and in particular relates to a preparation method of spices, and also relates to the prepared spices and their uses.

Background technique

Plant-based natural fragrances are fragrance-containing products extracted from the flowers, grasses, leaves, branches, trunks, stems, roots, skins, fruits, seeds, resins or balms of aromatic plants, most of which are oily or ointment Shape, few are resinous or semi-solid. Depending on their form and method of preparation, they are commonly called essential oils, tinctures, extracts, absolutes, balsams, or oleoresins, such as rose essential oil, date tincture, licorice extract, brandy balsam, and ginger oleoresin.

Among the preparation methods of plant-based natural spices, steam distillation is a common method. The water vapor is passed into the container containing the plant raw materials, and the volatile components are distilled out with the water vapor. The components of the prepared natural fragrance are aromatic volatile oils, which are generally referred to as essential oils. In steam distillation, water mainly plays three functions, namely, water dispersion, hydrolysis and thermal effect. The process of water action is simply summarized as follows: Wetting the surface of the raw material—water molecules penetrate into the cell tissue of the raw material—water replaces the essential oil or Trace dissolution—diffusion of essential oil into water—formation of azeotrope of essential oil and water—simultaneous distillation of essential oil and water vapor—condensation—separation of oil and water—essential oil. Except for the plant raw materials whose main aroma components are easily dissolved, hydrolyzed or decomposed in boiling water, most aromatic plants can be used to prepare essential oils by steam distillation. There are three main forms of steam distillation: water distillation, water distillation and water vapor distillation. The equipment for steam distillation mainly includes three parts: distillation still, condenser and oil-water separator. There are many deficiencies in the existing steam distillation process. For example, when extracting the oil in the water by extraction, a large amount of polluting organic extractant needs to be used; re-evaporation will destroy or decompose the effective components that are sensitive to temperature.

Reverse osmosis is a membrane separation technology that uses pressure difference as the driving force to separate the solvent from the solution to achieve the purpose of separation, extraction, purification or concentration. It is opposite to the direction of natural osmosis and is called reverse osmosis.

At present, a new method for preparing spices is still needed to obtain a novel spice product.
