Embodiment 1
[0036] Dissolve proanthocyanidin and vitamin C (100%) in a ratio of 1:2 in 95% ethanol to prepare a solution. Spray this solution evenly into the filter tow. After drying, the tow is made into a filter, and the filter is connected with a filterless red camellia cigarette to make a low-radical cigarette. The contents of proanthocyanidin and vitamin C contained in the filter tip of the cigarette are respectively 0.00015% and 0.0003% of the weight of the shredded tobacco in terms of weight ratio. Using ordinary Hongshan tea cigarettes as the reference cigarettes, the spin-trapped electron spin resonance technique was used to detect the gas-phase free radicals in the smoke of the above-mentioned low-radical cigarettes and the reference cigarettes. The detection condition is to use a smoking machine to imitate human smoking, with a flue gas flow rate of 400ml / min, smoking once every 2 seconds, with an interval of 1 minute. Use two layers of Cambridge filter paper to collect the tar, an...
Embodiment 2
[0038] According to the same method as in Example 1, the cigarettes with filters containing 0.00015% of the weight of the shredded tobacco by weight and the control cigarettes were tested, and calculated according to the above free radical scavenging rate calculation formula, The scavenging rate of gas phase free radicals is 22.6%. The specific results are shown in Table 2.
Embodiment 3
[0040] According to the same method as in Example 1, the cigarettes with filters containing 0.0003% of the weight of the shredded tobacco by weight and the control cigarettes were tested, and calculated according to the above free radical scavenging rate calculation formula, The scavenging rate of gas phase free radicals is 27.6%. The specific results are shown in Table 3.
