Problems solved by technology

This patent uses modern membrane treatment technology. Although the safety is guaranteed and no miscellaneous gas is introduced, the membrane treatment intercepts substances according to the molecular weight, and cannot extract the aroma components in tobacco to the greatest extent. high, expensive
[0005] Patent 200910006909.7 "Preparation method of wild perilla absolute oil" discloses a preparation method of wild perilla absolute oil. The preparation method of wild perilla absolute oil includes preparation of wild perilla cotyledon powder, organic solvent reflux extraction concentration, reflux Melting, freezing, suction filtration concentration, molecular distillation separation and purification, to obtain the absolute oil of wild perilla cotyledon. The reason why this patent has the conditions for molecular distillation after extraction, concentration and alcohol analysis is because of the protein, pectin, sugar content and other contents in wild perilla seed Very low, only simple extraction and concentration treatment is needed to clean it; however, for sun-cured tobacco, which has high protein, pectin and sugar content, this method is difficult to apply

Embodiment 1

[0046] A method for preparing sun-cured tobacco absolute by floating oil method, comprising the steps of:

[0047] Step (1), extraction: reflux extraction is performed on the sun-cured tobacco leaves, and the filtrate is filtered to obtain the extract;

[0048] Step (2), concentration: Concentrate the extract obtained in step (1) at a temperature of 65°C to a density of 1.15g / cm 3 , to obtain a concentrated solution;

[0049] Step (3), refrigerating and stratifying: refrigerating the concentrated solution obtained in step (2) for stratification to obtain the upper oily substance and the lower water-soluble substance;

[0050] Step (4), secondary concentration, alcohol analysis and filtration: at a temperature of 68°C, vacuum-concentrate the upper oily substance obtained in step (3) to obtain a secondary concentrate; add absolute ethanol to the secondary concentrate Carry out alcohol analysis, after no more precipitates are separated out, filter and remove the precipitates to...

Abstract

The invention relates to a method for preparing sun-cured tobacco net oil by an oil bleaching method and its application, and belongs to the technical field of tobacco flavors and fragrances. The method includes extraction, concentration, refrigerated layering, secondary concentration, alcohol precipitation, filtration, tertiary concentration, molecular distillation and a series of procedures to obtain sun-cured tobacco purée, and prepares tanning purée into an aromatizing module, which is applied to in cigarettes. The invention uses ethanol of different concentrations as extractant and extractant, abandons steps such as membrane filtration and petroleum ether extraction in traditional methods, and uses the principle of oil-water separation to skillfully separate oily substances and water-soluble substances in the sun-cured tobacco extract. , the macromolecular water-soluble substances such as sugars and proteins are removed, and the main aroma components in the sun-cured tobacco are retained to the greatest extent. The method is simple, safe, economical and has a high net oil yield. After the obtained cigarette oil is applied to cigarettes, the aroma of the smoke is full and mellow, the coordination is good, the thickness of the smoke is obviously improved, and the application effect is good.

Description

technical field [0001] The invention belongs to the technical field of flavors and fragrances for tobacco, and in particular relates to a method for preparing sun-cured tobacco absolute by a floating oil method and an application thereof. Background technique [0002] Molecular distillation technology is a new type of liquid-liquid separation technology that has developed rapidly in recent years. Because it is especially suitable for the separation and purification of high boiling point, heat-sensitive and easily oxidized materials, and has the advantages of high vacuum and low separation temperature, it has been widely used in food and medicine. It has significant advantages in the separation of natural products in the fields of daily chemicals, spices, etc., and can better enrich the characteristic aroma components of natural products. However, when molecular distillation technology is used to separate natural products, in a high vacuum and high temperature environment, ma...
