Abstract

The invention provides a method for preparing a crocus sativus extract with a pervaporation membrane. The preparation method specifically comprises the following steps: (1) taking dried crocus sativus and performing reflux extraction, so as to obtain crocus sativus extracting liquid; (2) concentrating the crocus sativus extracting liquid; (3) enriching aroma substances in waste liquid after concentration with the pervaporation membrane; (4) supplementing the enriched aroma substances back into concentrated solution, so as to prepare the cigarette-used crocus sativus extract. The cigarette-used crocus sativus extract prepared with the method reserves the special aroma of the crocus sativus; after the crocus sativus extract is added into a cigarette, the crocus sativus extract has the effects of increasing the volume of aroma of the cigarette, improving the smoke quality, giving fresh and sweet aroma to the cigarette, reducing stimulation, covering miscellaneous gases, enabling smoke to be gentle and fine, becoming good in comfort degree of an oral cavity, increasing the sweet feeling of the cigarette after taste, and so on; and the adaptability of the crocus sativus extract in the cigarette is enhanced.

Description

technical field [0001] The invention relates to a method for preparing flavors and fragrances for tobacco, in particular to a method for replenishing aroma substances through a pervaporation membrane and preparing a saffron extract for tobacco. Background technique [0002] In modern cigarette production, flavoring is considered to be a technology that cannot be ignored. Cigarette products are more distinctive due to the selection of various spices, and bring unique fragrance and satisfaction to consumers when they smoke. . Natural flavors are widely used in cigarettes due to their rich aroma, unique aroma characteristics, mellow aroma quality and other characteristics. At present, natural flavors for tobacco are mostly extracted by solvents. The biggest disadvantage of this process is that the concentration process has a large loss of aroma. The current situation of the loss of aroma substances caused by concentration in the process of solvent extraction has become a resea...
