There are two ways to determine whether cigarettes have deteriorated: direct observation and tasting. By observing whether the color of the cigarette shredded tobacco changes from bright golden yellow to dark yellow, it can be roughly distinguished. A more effective way is to taste the spoiled cigarettes, which have a special musty smell that old smokers can identify after a puff.

Whether cigarettes are spoiled or not, generally speaking, there are two situations, too dry and too moist, too dry cigarettes are very hard and brittle, and the taste of smoking is definitely different from fresh, and too dry cigarettes are generally stored for too long, such as cigarettes for several years. If it is too damp, of course, it will be moldy, and the appearance can be seen mildew, which is generally the outer packaging has been destroyed (the film on the strip has the function of blocking moisture).

If it is a well-packaged **cigarette, it will generally not deteriorate.

It's easy to tell, just sniff it. Fresh cigarettes have a characteristic aroma, aged cigarettes have a lesser aroma, and spoiled cigarettes have a musty smell.

Have a great day.

The storage time of cigarettes such as Chinese cigarettes is related to the environment in which they are stored, and under the appropriate temperature and humidity, cigarettes can be stored for 2-3 years without affecting the taste.

Cigarettes are relatively sensitive to outside temperature and humidity, and the length of shelf life is determined by the environmental conditions in which they are stored. So, cigarettes do not have a definite shelf life. If the cigarette is at the right temperature and humidity, the cigarette can be stored for 2-3 years without affecting the taste; If it is exposed to the sun and moisture, there is a possibility of mold; In a dry and cold place, such as in the refrigerator, some can even be stored for 5 to 10 years.

Cigarettes should generally not be stored for more than 2 years, beyond this period, even if there is no mold and deterioration, the taste will change, and the quality will be greatly reduced.

1. The reason why soft-pack cigarettes are more expensive.

To be precise, it should be that the medium and high-end cigarette soft packs are more expensive, and the low-grade cigarette hard boxes are more expensive.

There is an unwritten "soft and expensive principle" in mid-to-high-end cigarettes. In fact, it is very simple, and it is only soft pack cigarettes because of the low cost. Later, there were hard-box cigarettes that were more convenient to carry and preserve (soft-pack cigarettes were easy to fold in pockets).

It stands to reason that soft-pack cigarettes are about to be eliminated, but when there are fewer and fewer soft-pack cigarettes on the market, some people think that the original soft-pack cigarettes are still easy to smoke.

Yes. The shelf life of cigarettes varies according to the storage environment, and can be stored for two to three years when the environment is dry, or even for a year if the environment is not good. Cigarettes are easily affected by humidity and temperature.

Generally, cigarettes are not packed in bulk, they will dry up or moldy after one to two years, and it is more difficult to store at high temperatures or in the refrigerator.

The dangers of smoking.

It should be noted that tobacco smoke contains hundreds of harmful substances, among which 69 carcinogens are known to cause many cancers such as oral and pharyngeal malignant tumors, laryngeal cancer, esophageal cancer, stomach cancer, liver cancer, pancreatic cancer, kidney cancer, bladder cancer and cervical cancer.

In addition, smoking can lead to chronic obstructive pulmonary disease and cardiovascular and cerebrovascular diseases, which is one of the main causes of coronary heart disease, stroke, aortic aneurysm and peripheral vascular disease, and is an independent risk factor for cardiovascular and cerebrovascular diseases.

Because people's sense of smell and taste are affected in certain ways, it is inevitable that there will be deviations sometimes. In practice, it is difficult to distinguish between two kinds of spoiled smoke

First, it is difficult to judge when high-grade cigarettes are in the initial mold but there is no obvious mold (generally as long as there is a sugar and sour smell, it means that it has begun to mold);

Second, the green miscellaneous gas of low-grade cigarettes is mixed with mildew, and it is also difficult to determine whether it is mildew.

In order to improve the accuracy of identifying mildew smoke, the following methods can be adopted:

Wipe identification method: that is, when judging the white spots on the tobacco or tobacco stems from time to time, you can use a cotton swab to wet the water, and then wring out the water to wipe the white spots, if it is a mildew spot, you can wipe it off; If you can't wipe it off, it may be a spill or a white spot on the tobacco leaf or tobacco stem.

The tobacco was placed under a 10x magnification glass and observed that the hairs on the moldy tobacco were much more than those of the mold-free tobacco, and the color was dark and the luster was poor.

If you put the moldy tobacco under a biological microscope and look at it, you can clearly see the mold mycelium.

One sniff. If the aroma of the cigarette is pure, it means that the tobacco is normal and not damp. If there is a musty or other odour, the cigarette may be damp.

Two pinching. Dried tobacco is elastic and brittle, while wet tobacco is weak and easy to break.

Three looks. Normal tobacco should be oily and shiny. If the tobacco is wet, it will lose its luster and become dark.

Four listens. Rubbing the cigarette stick with your hand, there is a slight rustling sound normally. The damp cigarette sticks are soft and silent when rubbed by hand.

Five burns. After igniting the cigarette, the normal cigarette can generally spontaneously combust 2 3 or more. Tobacco sticks that are damp or have "knots" cannot be reached.

Six sucks. Cigarettes that are not damp can be smoked normally after being lit. On the other hand, the damp cigarette is easy to extinguish and hinder normal smoking.
