Problems solved by technology

However, due to the use of easily oxidized vitamin C, the color of the product becomes darker during storage and transportation, which leads to a decline in function
In addition, because the dissolution of vitamin C has its specific conditions, the production process is more complicated

Embodiment 1

[0016] The filter tip is used as a carrier, and the antioxidant tea polyphenol and the synergist citric acid are mixed with an appropriate amount of adhesive in a weight ratio of 1:1 to 20:1. In the process of bonding the tow, the above-mentioned tow adhesive is directly sprayed on the tow, so that the active ingredients in the adhesive are evenly bonded on the tow. Finally, the tow is processed into a nitroxide free radical suppressing cigarette filter. When the filter is connected to ordinary cigarettes, the inhibition rates of nitric oxide and oxygen free radicals are increased to 35-58% and 32-56% respectively, which effectively reduces the formation of nitrosamines in the body and has the effect of detoxification. effect. At the same time to NO 2 The inhibition rate also reached 10-16%.

Embodiment 2

[0018] The filter tip is used as a carrier, the antioxidant tea polyphenol and the synergist citric acid with a weight ratio of 1:1 to 20:1 are mixed with an appropriate amount of distilled water to prepare an infusion. The ordinary cigarette filter is placed in the soaking agent and soaked until the soaking agent completely soaks the filter fiber, so that the active ingredients in the soaking agent are evenly distributed on the surface of the filter fiber. Squeeze off excess soaking agent from filter fibers. By dehumidifying at low temperature, the cigarette filter for suppressing nitrogen oxide free radicals can be prepared. When the filter is connected to ordinary cigarettes, the inhibition rates of nitric oxide and oxygen free radicals are increased to 40-68% and 41-71% respectively. 2 The inhibition rate also reached 10-18%. During storage and transportation, the filter is resistant to discoloration and can maintain long-lasting function.

Embodiment 3

[0020] 90% tea polyphenols and 100% citric acid are prepared with distilled water to prepare tea polyphenols and citric acid with a weight concentration of 3%, wherein the weight ratio of antioxidant tea polyphenols and synergist citric acid is 2 :1~4:1. Place the polypropylene filter purchased on the market in the soaking agent until the soaking agent completely saturates the filter fiber, so that the active ingredients in the soaking agent are evenly distributed on the surface of the filter fiber, increasing the contact with the smoke. contact surface. Squeeze off the excess soaking agent in the filter fiber, and the liquid squeeze rate is about 40-50%. Then, dehumidify at low temperature, and the cigarette filter for suppressing nitrogen oxide free radicals can be prepared. 0.0015-0.02 grams of active ingredients loaded on each centimeter of cigarette filter tip (filter tip length). Finally, the filter is attached to the back of the regular cigarette. When oxygen free r...

Abstract

The cigarette filter tip has tea polyphenols and citric acid as effective components. Tea polyphenols and citric acid in the weight ratio of 1-20 to 1 are mixed into two adhesive, the two adhesive is sprayed to the surface of two, and the two is finally processed into cigarette filter tip capable of inhibiting nitrogen oxygen free dradical. Or, the active components are compounded with distilled water into soaking agent, and the soaking agent is used to soak filter tip fiber before rolling to eliminate humidity. The filter tip is jointed to cigarette and can result in an inhibiting rate to NO, oxygen free radical and No2 of 35-68 / %, 32-70 % and 10-16 % separately.

Description

technical field [0001] The invention relates to a cigarette filter and a preparation method thereof, in particular to a cigarette filter for suppressing nitroxide free radicals and a preparation method thereof. Background technique [0002] Because tobacco contains tar, harmful substances in solid phase and abundant tertiary amine saline. Especially the tertiary amine saline and alkali in the gaseous phase will generate various strong carcinogens including N-nitroso substances at the moment of smoking and inhalation, while nitrogen oxides are the carcinogenic N-nitrosamines. The main precursor, causing DNA oxidation, destroying gene bases, causing DNA damage, etc. [0003] In order to solve these problems, in recent years, both at home and abroad have adopted active carbon fiber or acetate fiber filter tip to remove the harmful substances of cigarettes. However, these measures can only suppress tar and solid-phase harmful substances, and have little ef...
