Abstract

The invention relates to a preparation method and application of a coffee baked fragrant substance. The method is implemented through the following steps that 1 to 5 parts of big particle coffee, 10 to 60 parts of medium particle coffee and 5 to 50 parts of small particle coffee are weighed according to the weight parts; then, 100 to 500 parts of polyhydric alcohol and 0.01 to 1 part of polysaccharide-iron compounds are added and are uniformly stirred, wherein the polysaccharide-iron compounds are dextrin polysaccharide-iron compounds or dextran iron compounds; reflux condensation is performedfor 0.5 to 3h at an oil bath being 150 to 250 DEG C; then, 200 to 2000 weight parts of solvents are added; ultrasonic extraction is performed for 10 to 60min; then, oscillation extraction is performed for 10 to 60min; then, centrifugation is performed for 4 to 15min; supernatant liquid is taken and is filtered by an organic filter membrane; then, reduced pressure distillation is performed; solvents are removed; the coffee baked fragrant substance is obtained. Through raw material refined preparation processing, in the separation process, by aiming at the characteristic ingredients of adding certain aroma and taste of smoke gas or improving the suction comfort (reducing the stimulation and the like), targeted extraction is performed to obtain the pure fragrant substance; smoke gas irritantor mixed gas substances such as macromolecular substances can be removed; the pure baked fragrant aroma substance is obtained.

Description

technical field [0001] The invention relates to a method for preparing a roasted aroma substance, in particular to a method for preparing a roasted coffee aroma substance, and also relates to the roasted coffee aroma substance obtained by the preparation method and its application, belonging to the field of flavors and fragrances for tobacco. Background technique [0002] Roasted aroma is a kind of aroma in roasted aroma, which is an important part of cigarette aroma. In recent years, there have been researches on the use of enzyme technology, microbial fermentation technology, Maillard reaction, etc. to enhance the aroma and produce aroma of traditional jujube extracts, which enriches the aroma of jujube extracts to a certain extent and increases the concentration of aroma components. content. Common cigarette additives such as malt extract are used to increase the roasted aroma of smoke. However, the roasted fragrance of the above-mentioned products obtained is not outst...
