Does instant coffee have caffeine? What kind of drink is this? You will find answers to these and other questions in the article. Instant coffee is a drink made from coffee beans, which are transformed into a water-soluble powder or granules using a variety of technological processes. A drink that tastes close to natural coffee is obtained by adding hot water.
Production
Many people wonder if instant coffee contains caffeine. When creating this product, coffee beans are roasted, crushed and treated with hot water. Then the resulting enriched drink is dried using different methods:
- Spray-dry or powder is made according to the "scatter drying" scheme. The extract is sprayed in a stream of hot air. As a result, it dries up and turns into a powder.
- Freeze-dry (sublimated) is produced according to the "freeze-drying" method. The frozen extract is dehydrated insublimation vacuum. This process preserves the ingredients of the product better, but it is more expensive due to more energy-intensive technology compared to other types of instant coffee.
- A granular product is made from a powder that is obtained by spray drying by aggregation, which is a procedure for moistening the powder to form granules.
At least one brand of soluble energy drink in the form of a concentrated liquid is known.
Presence of caffeine
So does instant coffee have caffeine in it? Usually people do not doubt that this substance is present in coffee. They consider it an integral component of the drink. In fact, the alkaloid determines the well-known strength of the invigorating drink. It has no smell, but at a high density it gives a noticeable bitterness to the drink.
The amount of caffeine does not determine either the specific taste or coffee aroma of the drink. Therefore, based on taste alone, it is impossible to say for sure whether instant coffee contains caffeine.
One can indirectly judge its presence by the invigorating effect of a drunk cup of drink. Caffeine has both negative and positive effects on the body. In addition, it has psychoactive properties. Therefore, manufacturers, along with simple instant coffee, release its decaffeinated version.
Amount of caffeine
Find out if instant coffee contains caffeine. Robusta beans are often used in the production of instant coffee. Atthis species does not have such an aroma and pronounced taste as Arabica. But it is cheaper, so its share in instant inexpensive varieties can be large.
Compared to Arabica, Robusta contains more caffeine, so the drink becomes strong. A cup of instant coffee contains 60-80 mg of caffeine, while a cup of natural ground coffee contains 80 to 150 mg.
In an invigorating drink of various brands, the percentage of caffeine is different (the norm is not less than 2.8%): Tchibo Exclusive - 3.1%, Nescafe Classic - 4.2%, Café Pele - 3.8%, "Jacobs Monarch" - 3.3%, "Black Card" Gold - 4, 2%, In decaffeinated coffee, there is always very little caffeine. There is a standard for this type of drink: the mass fraction of alkaloid cannot be more than 0.3%.
Be aware that not all types of decaffeinated beverages are strictly enforced. In addition, the use of cheap methods of decaffeination and incomplete extraction of the solvent from the grains affects the palatability of the product. There are many types of decaffeinated coffee from different manufacturers: Clipper, Nescafe, Matador, Ambassador, Le Cafe Mocca.
And there is also a natural version of decaffeinated coffee. It is known that coffee trees, the berries of which do not contain this alkaloid, are grown in Brazil. They are used in the manufacture of the product under the brand name Decaffito. Theobromine accumulates in the berries of these amazing trees, which in large quantities negatively affects the human body.
Scientific research
So we answered the question of whether instant coffee contains caffeine. Scientistsfound that a serving of an invigorating substance of 50-80 mg increases efficiency and improves mood, 250-300 mg can disrupt the heartbeat, 400-500 mg contribute to depression, and 10,000 mg cause death.
Comparison
You already know if there is caffeine in Nescafe instant coffee. Many people believe that natural coffee has more caffeine than instant coffee. There is no definite answer here, since instant coffee contains artificial caffeine. The manufacturer himself decides how much of this substance will be contained in the product.
Instant coffee
Are you still asking if freeze-dried instant coffee has caffeine? This drink completely preserves all the useful qualities of coffee beans, their taste and aroma. It differs from granulated and powdered instant product, whose manufacturing techniques negatively affect the properties of the drink.
Freeze-dried instant coffee contains as much caffeine as natural coffee. Nutritionists advise a he althy person to drink no more than two cups of a soluble freeze-dried product per day. Granulated or powder coffee can be consumed up to five cups per day.
Composition
Instant coffee is divided into two types depending on the preparation method: freeze-dried and regular. The second is obtained by grinding coffee beans, drying them with steam. Freeze-dried is produced by freezing powderedgrains. It has a lower acidity, it has more useful components.
Since the harvesting process is very expensive, the price of such coffee is higher than that of a simple one. The sublimated soluble product has substances useful for humans that are present in cereals: vitamin PP, which has a positive effect on the nervous system, improves brain activity, saturating blood vessels with oxygen.
It also affects the metabolic processes that occur in the human body, splitting carbohydrates with fats, turning them into energy. This type of coffee contains vitamin B2, which is involved in the transformation of carbohydrates and proteins into energy.
It is known that freeze-dried coffee has the same minerals as in natural grains. Basically it is phosphorus, iron, calcium, sodium and nitrogen.
Harm and benefit
Instant coffee affects the human body in the same way as natural coffee. For example, in these drinks, the level of content of invigorating substances is almost the same - about 60 ml in soluble, 80 ml in grain. Despite the lower caffeine content, freeze-dried coffee also has a negative effect on the body: the nervous system suffers from caffeine, high acidity affects the function of the gastrointestinal tract (adding milk reduces the level of acidity).
It is known that the main element caffeine (regardless of the method of manufacture) increases blood pressure. This means that hypertensive patients cannot drink such a drink. You can not abuse coffee and men after 35 years, as theyare at risk for the development of vascular and heart diseases.
It is important to know: the drink we are considering is contraindicated for hypertensive patients, but for hypotensive patients (suffering from low blood pressure) in moderation it can be useful. You also need to pay attention to the high content of acids. If the product is used every day, the acidity of the oral cavity, gastric juice and saliva will increase. The enamel of the teeth is also rapidly destroyed.
Harm can be reduced by rinsing your mouth with running water after drinking. You can not drink coffee and those who have gastrointestinal ailments. Breastfeeding and pregnant women should avoid this drink. After all, caffeine accumulates in breast milk, has a negative effect on the nervous system of the fetus.
