Embodiment 1

[0029] Preparation of grape polyphenol nanoliposome composite film and composite filter rod.

[0030]1. Take 30 mg of grape polyphenols sample with a purity of 98.5%, dissolve it in 50 mL of 0.05 mol / L phosphate buffer, and prepare a grape polyphenols solution. Accurately draw 20mL of grape polyphenol solution, dissolve 16mg of Tween 80 in it, heat to 60°C and keep constant temperature, stir vigorously to obtain grape polyphenol emulsion. According to the total mass of phospholipids and cholesterol is 24mg, and the mass ratio of phospholipids and cholesterol is 2:8, dissolve in 8mL of 60°C dehydrated ethanol, use a syringe to inject at a constant speed into the grape polyphenol emulsion at a constant temperature, keep the system at a constant temperature, and stir 5min to form an emulsified grape polyphenol liposome suspension. The obtained grape polyphenol liposome suspension was placed in a 500mL round bottom flask, concentrated under reduced pressure at 0.01MPa for 30min, ...

Embodiment 2

[0037] Repeat Example 1, with the following differences: the sample size of grape polyphenols is 20 mg, the mass ratio of phospholipids and cholesterol is 1:9, and the amount of absolute ethanol is 6 mL.

Embodiment 3

[0039] Repeat Example 1, with the following differences: the grape polyphenol sample size is 20mg, the phospholipid and cholesterol mass ratio is 3:7, the absolute ethanol consumption is 6mL, the DHMP treatment pressure is 300Mpa, and the grape polyphenol nanoliposome composite membrane Add evenly to the opened cellulose acetate tow at a mass ratio of 15%.

Abstract

The invention discloses a grape procyanidin nano-liposome composite membrane and application of the membrane in cigarettes. Grape procyanidin is prepared into emulsified lipidosome suspension liquid, reduced-pressure vaporization and DHPM treatment are performed to obtain a grape procyanidin nano-liposome, and then the grape procyanidin nano-liposome is compounded with polysaccharide to obtain the grape procyanidin nano-liposome composite membrane. The composite membrane is evenly added to a non-opened cellulose acetate tow to prepare a composite filter rod for the cigarettes. The composite membrane can play the protection effect on the grape procyanidin, avoid or reduce loss of grape procyanidin activity in the cigarette processing and storage process, can also achieve slow release of the grape procyanidin in the cigarettes, prolongs an activity period of the grape procyanidin while endowing biological activity, can remarkably improve the smoking quality of the cigarettes, reduce the content of hydrogen cyanide and free radicals in main stream smoke and improve the overall functionality and aroma quality of cigarette products. The preparation process is simple and rapid, the products are stable in property after long-time placement, the production process is green and environment-friendly, and the composite membrane has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of nano-liposome application and cigarette filter production, and in particular relates to a grape polyphenol nano-liposome composite membrane capable of improving the smoking quality of cigarettes. At the same time, the invention also relates to the specific application of the glucopolyphenol nanoliposome composite film in cigarette production. Background technique [0002] Since the first report of liposome structure by British scholar Bangham in the 1960s, liposomes have received more and more attention; in 1971, British scientists Rymen and others began to use liposomes as drug carriers, making them widely used in the pharmaceutical field. It has been widely used and rapidly developed into a new drug delivery system. As a carrier, the application of nanoliposomes in the fields of food and flavors and fragrances has the following excellent properties: 1) The inner water phase can embed water-soluble subs...
