Embodiment 1

[0017] A preparation method of perilla absolute oil and its application in cigarette flavoring, including perilla leaf raw material pretreatment, organic solvent reflux extraction and concentration, remelting and freezing, suction filtration concentration, molecular distillation separation and purification, absolute oil GC / MS Analysis and aroma application, the specific process steps are as follows:

[0018] (1) Perilla leaves are dried and pulverized at 40° C. to pass through a 20-100 mesh sieve to obtain perilla leaves powder.

[0019] (2) Put the perilla leaf powder obtained in step (1) into a reflux extraction tank, add ethanol, concentrate after reflux extraction for 72 hours, and obtain the primary ointment of perilla leaves.

[0020] (3) Add ethanol to the initial extract of perilla leaves obtained in step (2), redissolve and freeze for 12 to 24 hours, then concentrate by suction to obtain perilla leaf crude oil.

[0021] (4) Selectively separate and purify the perilla...

Embodiment 2

[0026] A preparation method of perilla absolute oil and its application in cigarette flavoring, which comprises the steps of putting perilla leaf powder into a refluxing extraction tank, adding ethanol, refluxing and extracting for 48 hours, and concentrating to obtain primary perilla leaf ointment; Add ethanol to remelt and freeze for 24 hours, then concentrate by suction filtration to obtain perilla leaf crude oil; use molecular distillation technology for selective separation and purification, and enrich the components below 120°C to obtain perilla leaf absolute oil, which is analyzed by GC / MS After identifying its main components, it is then used to flavor cigarettes.

Embodiment 3

[0028] A preparation method of perilla absolute oil and its application in cigarette flavoring, which comprises the steps of putting perilla leaf powder into a refluxing extraction tank, adding ethanol, refluxing and extracting for 36 hours, and concentrating to obtain perilla leaves primary cream; Add ethanol to remelt and freeze for 24 hours, then concentrate by suction filtration to obtain perilla leaf crude oil; use molecular distillation technology for selective separation and purification, and enrich the components below 160°C to obtain perilla leaf absolute oil, which is analyzed by GC / MS After identifying its main components, it is then used to flavor cigarettes.

Abstract

The invention discloses a preparation method of folium perillae neat oil, which consists of preparing folium perillae powder, organic solvent reflowing, extracting and concentrating, re-suspending, freezing, sucking filtrating and concentrating, and molecular distillation separating and purifying to obtain the folium perillae neat oil. The obtained su cotyledon neat oil is used in the cigarette flavoring, can improve the fragrance and increase the smoothness and fine degree of the smoke, and reveals unique delicate fragrance.

Description

technical field [0001] The invention relates to a preparation method of perilla absolute oil. Background technique [0002] Wild perilla is a plant of the genus Lamiaceae, also known as tortoise leaf grass and dog sun grass, sweet in nature and bitter in taste, perennial herb. It has important medicinal functions and can be used to treat sore throat, rheumatic cold, gastritis, joint swelling and pain, early cancer, snake bites and other diseases. And as a characteristic condiment, its unique fragrance has been widely accepted. With the in-depth study of its chemical composition, wild perilla absolute will also be effectively used in the process of flavoring cigarettes. [0003] At present, the method widely used at home and abroad is: after the raw material is pretreated, add a certain amount of organic solvent, extract the volatile and semi-volatile components in the wild perilla cotyledon leaves by simultaneous distillation extraction or steam distillation, and obtain wil...
