Quinic acid. It gives the coffee a slight sour taste. In addition, it is a chemical substance of the Tamiflu drug.

3,5 dicaffeoylquinic acid.

Dimethyl disulfide.

Roasted green coffee beans produce a substance that is only present in the initial stages of brewing coffee, and it is also a good thing, one of the chemicals that gives human feces the smell.

Acetylmethyl methanol.

Acetylmethyl methanol, a flammable yellow liquid that helps give butter its smell, is an ingredient in artificial flavoring in microwave popcorn.

Putrescine. What makes spoiled meat so poisonous? Here's the answer. Cadaverine putrescine is produced by the breakdown of amino acids by E. coli in meat. Fuscine is naturally found in coffee beans, and as you might guess from its name, it smells foul.

Fenugreek. In terms of chemical structure, it is a folic acid molecule with a methyl group. Fenugreek breaks down to form pyridine, which gives coffee its sweet, earthy smell and prevents oral streptococcus bacteria from eroding your teeth from attaching to your teeth.

Many people have the experience of not being able to sleep due to high spirits after drinking coffee, because there is a conductive substance called adenosine in the body, which is able to control nerve activity, resulting in slowed breathing, reduced mood, reduced gastric acid secretion, and diuretic effects. Caffeine will counterfeit adenosin, making the body think that the effect of adenosine has occurred, making you feel energetic, stomach acid increases, urination more frequent, and naturally less likely to fall asleep. It is important to note that the brief lucidity caused by this caffeine does not indicate that the physical strength is really restored.

In recent years, due to the increasing attention to the problem of calcium loss and osteoporosis, there are also considerable doubts about coffee. The relationship between caffeine intake and osteoporosis is still being studied, and there is no direct evidence that caffeine causes osteoporosis, but some studies have shown that caffeine increases calcium loss. Therefore, you should eat more high-calcium foods to supplement calcium, such as preparing custard slices or custard cake to enjoy with coffee, which can not only replenish calcium, but also make coffee more delicious.

Equatorial regions such as India.

Coffee is made with coffee beans and a variety of cooking utensils, and coffee beans refer to the kernels in the fruit of the coffee tree, and then roasted in an appropriate way, which will show different degrees of sweetness, acidity, body or cleanliness in taste.

Coffee is a beverage made from roasted and ground coffee beans. As one of the world's three major beverages, it is the main drink popular in the world along with cocoa and tea. Coffee has a history of more than 100 years since it was introduced to Wenchangmai Town, Hainan, China in 1898.

In recent years, due to the increasing popularity of domestic coffee culture, the coffee we have come into contact with is no longer the same as in the past, and it is no longer in the era of instant coffee. But it's still one of the most popular drinks in the world.

Coffee contains caffeine in it.

Caffeine is a plant alkaloid.

It can be found in many plants. As a natural insecticide, it paralyzes insects that swallow caffeinated plants. The most commonly used caffeinated plants include coffee, tea, and some cocoa.

Other trees that are not commonly used include Paraguayan holly and guarana, which are commonly used to make tea or energy drinks.

The most dominant caffeine in the world** is coffee beans.

The seeds of the coffee tree), and the coffee beans are also the raw material for coffee. The caffeine content in coffee depends greatly on the variety of coffee beans and the method used to make the coffee, and even the caffeine content in the beans on the same tree can vary greatly.

In general, the caffeine content in a cup of coffee ranges from Arabic espresso.

40 mg in espresso to 100 mg in espresso. Dark roast coffee generally contains less caffeine than light roast coffee because roasting reduces the caffeine content in the beans. Coffea arabica generally has a lower caffeine content than coffea chinensis. Coffee also contains trace amounts of theophylline.

But it does not contain theobromine.

Two caffeine aliases, the Mateine and Guarana Factor, evolved from these two plants.

The world's most important caffeine** is coffee beans (the seeds of the coffee tree), which are also the raw materials of coffee.

The upper limit of caffeine intake

A 250ml jar of Red Bull.

The content of caffeine is about 50 mg, the caffeine content in a cup of 240 ml of freshly brewed coffee is about 95-200 mg, and the upper limit of caffeine intake should be about 400 mg per day.

However, everyone's acceptance of caffeine is different, some people have a high acceptance of caffeine, drinking coffee, black tea, etc. as water, and some people will have hand tremors and palpitations when they drink a little.

Symptoms such as rapid heartbeat. For the former, it is recommended to strictly follow the upper limit of 400 mg of caffeine per day, and for the latter, it is recommended to try not to consume caffeine.

According to the British "Sunday Times", United Nations researchers have found that many young and middle-aged people drink coffee every day contain acrylamide, a carcinogen! Fried and baked foods also have a fairly high acrylamide content. Scientists recommend reducing your intake.

Acrylamide is a carcinogen that is produced during cooking, especially at high temperatures, such as frying and baking. Dr. Angelica Trischer, a scientist at the research committee, said that the highest levels of acrylamide were found in French fries, potato chips, biscuits and bread, but as the research went further, it was found that other foods also produced large amounts of acrylamide, such as roasted coffee beans. Studies have found that coffee drinkers consume 13 to 39 levels of acrylamide, which is one-third of our daily acrylamide intake.

The amount of acrylamide in a cup of coffee depends on how strong the cup is, how the beans are roasted, and how well they are roasted. There are also slight differences between instant coffee and freshly ground coffee. However, the content is about 290 micrograms per kilogram.

The new study was done jointly by the World Health Organization and the Food and Agriculture Organization of the United Nations. The survey data includes 17 countries, including the United Kingdom, and a graph of acrylamide intake is depicted according to different dietary habits in each country. Those who regularly eat fresh, steamed foods consume much less acrylamide than those who always eat fried or baked.

Since the 50s of the 20th century, acrylamide has been used in industry as a chemical for water purification. In 2002, researchers in Sweden found high levels of acrylamide in some foods. Animal studies have shown that ingestion of high amounts of acrylamide may cause cancer and reproductive problems.

The UK Food Standards Agency and the European Union have issued a policy for the food manufacturing industry to reduce the amount of acrylamide produced in the production process.

Many British scientists believe that acrylamide is likely to be harmful to the human body, and it is recommended to reduce the intake as much as possible.
