JPH03198766A - Tobacco filter of safflower oil - Google Patents

Abstract

PURPOSE:To obtain a tobacco filter capable of providing satisfaction in smoking with low contents of nicotine and tar without inhibiting aroma and taste by encapsulating safflower oil and adding the resultant encapsulated oil to the filter. CONSTITUTION:A tobacco filter obtained by treating safflower oil with, e.g. polyvinyl alcohol and a surfactant sorbitan monostearate or corn starch to provide slurry safflower oil capsules and adding the resultant safflower oil capsules to a filter sheet so as to afford about 3% amount thereof based on the filter sheet with a spray.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cigarette filter that achieves low nicotine and low tar content, does not impede the aroma and taste, and provides a satisfying smoking experience.

(Prior Art) Conventionally, in order to achieve low nicotine and low tar content, activated carbon has been attached or filled to an acetate filter or a nonwoven filter.

In addition, there are also cigarettes that have a large number of fine holes in the wrapping paper around the outer periphery of the cigarette or in the outer periphery of the tip, and draw in outside air to dilute the smoke and make it low in nicotine and low in tar.

(Problems to be Solved by the Invention) L: In conventional products that use activated carbon, when the activated carbon adsorbs cigarette smoke and then desorbs the smoke, which has become low nicotine and low tar, it creates a blue gas that inhibits the flavor of the smoke. It has the disadvantage of producing an odor. This grassy smell is commonly called charcoal cheese.

Moreover, activated carbon has the drawback that it has a high ventilation resistance, making it difficult to smoke, and the filtration rate of nicotine and tar is only 4 at most.
There is also the drawback that it is between 0 and 50%.

In addition, the above-mentioned products provided with micropores have the disadvantage that they do not provide the satisfaction of smoking because they draw in outside air at the same time as the cigarette smoke and dilute the cigarette smoke to achieve low nicotine and low tar content.

An object of the present invention is to provide a cigarette filter that has low nicotine and low tar content without deteriorating the flavor and taste, and which does not make smoking difficult or unsatisfactory.

(Means for solving the problem) Safflower oil is a semi-drying oil containing 70% linoleic acid, and is a high-quality edible oil.It is harmless to hygiene and has the property of being odorless even when heated. have It also has the property of enveloping and removing nicotine and tar. The present invention was made based on this new knowledge, and is characterized in that safflower oil is encapsulated and contained in a cigarette filter.

(Function) Since the safflower oil is encapsulated, it prevents the safflower oil from penetrating into the filter fibers and staining the filter. However, since cigarette smoke has a temperature of 40°C and contains 60% water, the capsule ruptures due to the smoke during smoking, and the safflower oil easily comes into contact with the cigarette smoke, and the safflower oil removes the nicotine and tar contained in the smoke. It can be removed by wrapping, and since safflower oil is odorless even when heated by smoke, it does not impair the flavor of the smoke.

(Example) 10g of safflower oil was collected in a container, and polyvinyl alcohol P
Mix with 10 g of 25% aqueous solution of 500 and add 70 g of water.
g, surfactant sorbitan monostearate 1-0, 1
g, and 0.1 g of sorbitan monooleate were added thereto, and the mixture was stirred for 10 minutes at 1 liter, 100 orp using a homomixer. After 5 minutes, 5g of cornstarch was added and further stirred with a homomixer at 1l100Orp.
After a few minutes, it becomes a slurry of encapsulated safflower oil.

This is placed in a plug machine tank, and 3% slurry of safflower oil capsules is added to the filter sheet by spraying.

After winding up the plug into a plug with a diameter of 7.0 mm and a length of 102 mm using a winding machine, the plug is cut into six pieces to form filter tow.

This single 17 mm long filter tow is connected to one end of a cigarette to form a tip.

The nicotine of the filter chip according to the embodiment of the present invention and the conventional commercially available cigarette filter chip,
A comparison of the filtration rates of tar is as follows. The longevity of Taiwanese cigarettes was used as the conventional cigarette.

Since no fine holes are made in the wrapping paper, the effect is that smoking W4h1 can be obtained.

Furthermore, since the encapsulated safflower oil is in the form of a slurry, it can be rolled up onto a filter without adding plasticizers or adhesives, resulting in improved manufacturing efficiency.
