Problems solved by technology

However, when dill seeds are extracted by conventional steam distillation method, since the extraction process needs to go through high temperature, the decomposition, polymerization and configuration transformation of active ingredients are prone to occur, which will affect the aroma of dill oil.
Moreover, when the dill seeds are extracted by steam distillation, some impurities in the dill seeds coexist with the mucilage of the resin, and contain more non-aromatic components. When applied to cigarettes, it will bring oral residues, tongue coating, etc. shortcoming

Embodiment 1

[0027] (1) steam distillation obtains dill oil;

[0028] (2) Dill oil is diluted with 30% aqueous ethanol in a ratio of 1:15 (g:mL);

[0029] (3) Add 40% food-grade β-cyclodextrin vesicle wall material and 5% food-grade sodium sulfate in the diluent;

[0030] (4) Stir evenly in a constant temperature water bath at 45°C, let it stand for stratification after uniformity, and at this time, the dextrin layer can be made into microcapsule products;

[0031] (5) Continue to add 2 times the volume of absolute ethanol to the dextrin phase, stir fully, and release the capsule core;

[0032] (6) centrifuge, get ethanol layer;

[0033] (7) Distill the ethanol layer under reduced pressure to reclaim ethanol to obtain dill oil.

Embodiment 2

[0035] (1) Use 40% ethanol aqueous solution as a solvent, soak the dill raw material for 24 hours according to the raw material and solvent 1:20 (g:mL), to obtain dill extract;

[0036] (2) adding 40% food-grade β-cyclodextrin vesicle wall material and 10% food-grade sodium chloride to the extract;

[0037] (3) Stir evenly in a constant temperature water bath at 60°C, let it stand for stratification after uniformity, and at this time, the dextrin layer can be made into microcapsule products;

[0038] (4) Continue to add 4 times the volume of absolute ethanol to the dextrin phase, fully stir, and release the capsule core;

[0039] (5) centrifuge, get ethanol layer;

[0040] (6) Distill the ethanol layer under reduced pressure to reclaim ethanol to obtain dill oil.

Embodiment 3

Abstract

The invention provides a microcapsule purification method and application of dill oil for cigarettes. The method comprises the following steps: by using a 30-60 vol% ethanol water solution as a solvent, preparing dill seeds and the solvent into a dill extracting solution in a mass ratio of 1:(3-20); (2) adding a 30-60 wt% cyclodextrin capsule wall material and a 5-40 wt% inorganic salt or inorganic alkali into the extracting solution; (3) stratifying the mixed solution at 30-60 DEG C to obtain a solvent layer and a dextrin microcapsule layer; (4) adding anhydrous ethanol into the separated dextrin microcapsule layer, sufficiently stirring, and releasing the capsule core; and (5) separating the ethanol layer out of the mixed solution, and finally carrying out vacuum distillation on the ethanol layer to obtain the dill oil for cigarettes. The method can obtain the dill oil for cigarettes by purification, and has the advantages of simple purification process, mild conditions and favorable purification effect; and the purified dill oil can cover the impure gas and lower irritation when being used in cigarettes.

Description

technical field [0001] The invention relates to a method for preparing cigarette essence and fragrance, in particular to a method for purifying microcapsules of dill oil for cigarettes and its application. Background technique [0002] Dill is an umbelliferous plant, also known as fennel. Dill seeds are often used as a seasoning in food production, and can also be used to prepare food flavors, which have the effects of increasing appetite and strengthening the spleen. Dill essential oil can also be used in tobacco as a flavor and fragrance, which can cover up miscellaneous gas and reduce irritation. However, when dill seeds are extracted by the conventional steam distillation method, since the extraction process requires high temperature, the decomposition, polymerization and configuration transformation of the active ingredients are prone to occur, which affects the aroma of dill oil. Moreover, when the dill seeds are extracted by steam distillation, some impurities in th...
