Abstract

The invention discloses a preparation method for a Pistacia weinmannifolia tobacco essence. The preparation method comprises the steps of: putting 3-10-mesh Pistacia weinmannifolia leaves or branches or barks which are sequentially dried and crushed into a carbon dioxide supercritical extraction kettle, carrying out carbon dioxide supercritical extraction and first-level decompression and separation under optimized conditions, and dissolving products of the first-level decompression and separation into ethanol or propylene glycol, so as to prepare and obtain Pistacia weinmannifolia tobacco essence and perfume. After being subjected to smoke panel test and comparison, the Pistacia weinmannifolia tobacco essence has the advantages that the richness and the exquisite feeling of smoke and fragrance of cigarettes can be obviously enhanced, the faint scent, spicy fragrance, woody fragrance, fruity fragrance and flower fragrance of the cigarettes are mainly added, the fragrance is tender, and the essence is volatile and is lightly diffused and has good compatibility with the smoke and the fragrance of the cigarettes.

Description

Technical field [0001] The invention belongs to the development field of tobacco flavors and fragrances, and specifically relates to a method for preparing tobacco fragrance wood flavors and fragrances by using carbon dioxide supercritical extraction technology. Background technique [0002] Flavoring technology is one of the core technologies for constructing cigarette brand characteristics and quality style, and flavors and fragrances are the key to flavoring technology. Although domestic flavor and fragrance companies have made some achievements in the development of various flavors and fragrances, there is still a big gap compared with the world's advanced level, which is mainly reflected in the high degree of dependence on foreign flavors and fragrances and the lack of independent core knowledge. Fragrance technology and other aspects of property rights. In addition, the statistical results show that the use of naturally extracted flavors and fragrances accounts for most of...
