preparation example Construction

[0029] The application provides a method for preparing a highly stable tobacco natural flavor extract, comprising the following steps:

[0030] (1) Pulverize the tobacco, pass through a 40-400 mesh sieve, add water 3-20 times the weight of the tobacco leaves, mix and stir evenly, and ultrasonically treat for 0.5-2 hours to obtain a suspension A; in this application, the tobacco includes One or more combinations of tobacco leaves, tobacco leaf powder, recycled shredded tobacco or tobacco leaf leftovers can all realize the technical solutions of the present application.

[0031] (2) Distill the suspension A in a steam distillation device at 100-180°C for 2-6 hours, separate the collected liquid to obtain tobacco essential oil, and at the same time pour the separated water phase back into the suspension A to obtain the suspension B;

[0032] (3) Centrifuge or filter the suspension B (70-100 mesh) to obtain the tobacco extract C, add the filter residue to water 5-10 times the weig...

Embodiment 1

[0038] (1) Weigh 100 g of tobacco leaf waste, crush it with a mechanical pulverizer, pass through a 40-mesh sieve, add water 8 times the weight of the tobacco leaf raw material, stir evenly, and conduct ultrasonic treatment at 160w for 30 minutes at room temperature. Add the suspension of tobacco dust after ultrasonic treatment into the steam distillation device (connect the steam generator and the condensation device), feed water steam at 130°C for distillation for 3 hours, and separate the tobacco essential oil from the oil phase in the condensate, and the separated The aqueous phase is poured back into the tobacco dust suspension.

[0039] (2) Filter the distilled tobacco powder suspension with 60 mesh and 100 mesh filter screens respectively to obtain tobacco extract and filter residue, add 6 times the weight of water to the filter residue again, stir and extract at 80°C for 30 minutes and then Perform 60-mesh and 100-mesh filter screen filtration, combine the two tobacco ...

Embodiment 2

[0042] (1) Weigh 100g of tobacco leaf leftovers, use a mechanical pulverizer to crush it, pass through a 60-mesh sieve, add water 12 times the weight of the tobacco leaf raw material, and NaCl of 2% of the tobacco leaf weight. After stirring evenly, 180w ultrasonic treatment at 50°C 30 minutes. Add the soot powder suspension after ultrasonic treatment into the steam distillation device, keep the solution in a slightly boiling state for distillation by electric heating for 4 hours, collect the condensed mixed liquid, and add 1 / 2 and 1 / 3 volumes of The n-hexane is extracted twice, the two extracts are combined, the tobacco essential oil is separated by vacuum concentration, and the condensed water phase after extraction is combined into the tobacco powder suspension.

[0043] (2) Centrifuge the distilled tobacco powder suspension at 4000rpm to obtain tobacco extract and filter residue, add 6 times the weight of water to the filter residue again, stir and extract at 80°C for 30 m...

Abstract

The invention relates to a method for preparing a high-stability tobacco natural flavor extract. The method comprises the following steps: extracting out essential oil easy to volatile in tobacco by using a vapor distillation process, further filtering a tobacco water extract, performing vacuum concentration, returning the extracted essential oil into the concentration liquid, adding concentratedchick-pea yellow slurry, performing high-intensity homogenization emulsion so as to obtain an oil-in-water emulsion, enabling flavor essential oil to be uniformly distributed in a flavor concentrationliquid in a nano oil droplet manner, and increasing the volume ratio of emulsion-system tobacco essential oil, so as to prepare a semisolid tobacco extract product. By adopting the technical scheme,the tobacco essential oil and the extraction concentration liquid are combined and emulsified, and the flavor of the extract is completely derived from a tobacco raw material, so that the flavor is natural; and in addition, as the tobacco essential oil easy to volatile is wrapped in an emulsion water phase in the oil droplet manner, volatilization loss of the flavor of the tobacco flavor extract in storage and use can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of preparation of spices, in particular to a preparation technology of spices for tobacco, especially to a preparation method of highly stable tobacco natural flavor extract. Background technique [0002] In tobacco processing and production, a large amount of tobacco powder fragments, waste tobacco leaves, etc. will be produced. It is of great significance to fully extract the tobacco flavor components in these tobacco waste materials and then apply them to tobacco products, which is of great significance for saving resources, protecting the environment and improving economic benefits. . [0003] Tobacco extract is a kind of extract with tobacco aroma, which is made from tobacco as raw material through extraction and concentration process. It is widely used in the flavoring of cigarettes and reconstituted tobacco leaves, which can increase the natural smoke flavor of tobacco products. , reduce irritation a...
