Is there caffeine in instant coffee ? 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 tree beans that are transformed into water-soluble powder or granules using a variety of technological processes. A drink whose taste is close to natural coffee is obtained after adding hot water.
Manufacture
Many people wonder if there is caffeine in instant coffee. When creating this product, coffee beans are roasted, crushed and processed with hot water. Then the resulting enriched drink is dried by various methods:
- Spray ride or powder is made according to the "dispersion drying" scheme. The extract is sprayed in a stream of hot air. As a result, it dries and transforms into powder.
- Freeze-dryd (freeze-dried) is produced according to the method of “freeze drying”. The frozen extract is dehydrated in a vacuum by sublimation. This process saves the constituent substances of the product better, but it is more expensive due to the more energy-intensive technology in comparison with other types of instant coffee.
- The granular product is made from powder, which is obtained by spray drying by means of aggregation, which is a process of moistening the powder to create granules.
At least one brand of soluble vigor drink is known as a concentrated liquid.
Caffeine
So is there instant caffeine in instant coffee? Usually people have no 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 an invigorating drink. It is odorless, but at high density it gives a noticeable bitterness to the drink.
The amount of caffeine determines neither the specific taste nor the coffee aroma of the drink. Therefore, based only on taste sensations, it is impossible to assert for sure whether there is caffeine in instant coffee.
One can judge indirectly its presence by the invigorating effect of a drunk cup of drinking. Caffeine has both negative and positive effects on the body. In addition, he has psychostimulating qualities. Therefore, manufacturers, along with simple instant coffee, produce its decaffeinated version.
Amount of caffeine
Find out if instant coffee contains caffeine. Robusta beans are often used to produce instant coffee. This species has no such aroma and pronounced taste as that of Arabica. But it is cheaper, so its share in soluble inexpensive varieties can be large.
Compared to Arabica - Robusta contains more caffeine, so the drink is made strong. In a cup of instant coffee contains 60-80 mg of caffeine, and in a cup of natural ground - from 80 to 150 mg.
In the 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, caffeine is always very little. There is a standard for this type of drink: the mass fraction of alkaloid cannot be more than 0.3%.
Please note that not all types of caffeine-free drink are strictly enforced. In addition, the use of cheap methods of removing caffeine and incomplete extraction of solvent from grains affects the taste of the product. There are many types of caffeinated coffee from different manufacturers: Clipper, Nescafe, Matador, Ambassador, Le Cafe Mocca.
And there is also a natural version of caffeine-free coffee. It is known that coffee trees, whose berries this alkaloid does not contain, are grown in Brazil. They are used in the manufacture of a product under the Decaffito brand. 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 whether caffeine is contained in instant coffee. Scientists have found that a portion of an invigorating substance of 50-80 mg increases performance and improves mood, 250-300 mg can disturb the heartbeat, 400-500 mg contribute to the onset of depression, and 10,000 mg - death.
Comparison
You already know if there is caffeine in Nescafe instant coffee. Many people think that natural caffeine has more caffeine than instant coffee. There is no single answer, as there is artificial caffeine in instant coffee. The manufacturer himself decides how much of this substance will be contained in the product.
Instant coffee
Are you still asking if there is caffeine in freeze-dried instant coffee? This drink fully preserves all the beneficial qualities of coffee beans, their taste and aroma. It differs from the granular and powder soluble product, the manufacturing technology of which negatively affects the properties of the drink.
Freeze-dried instant coffee contains as much caffeine as natural. Nutritionists advise a healthy person to drink no more than two cups of a soluble freeze-dried product per day. Granular or powder coffee can be consumed up to five cups per day.
Structure
Instant coffee is divided into two types, depending on the method of preparation: freeze-dried and regular. The second is obtained by grinding coffee beans, drying them with steam. Freeze-dried is produced by freezing powdered grains. It has a lower acidity, it has more useful components.
Since the procurement process is very expensive, the price of such coffee is higher than simple. Freeze-dried soluble product has substances that are beneficial for humans, present in the grain: vitamin PP, which positively affects the nervous system, improves brain activity, saturating blood vessels with oxygen.
It also affects the metabolic processes that occur in the human body, breaking down carbohydrates with fats, turning them into energy. In this type of coffee, there is vitamin B2, which is involved in the processes of transformation of carbohydrates and proteins into energy.
It is known that freeze-dried coffee contains the same mineral substances as natural grain. Basically it is phosphorus, iron, calcium, sodium and nitrogen.
Harm and Benefit
Instant coffee affects the human body as well as natural. For example, in these drinks the level of energizing substances is almost the same - in soluble about 60 ml, in grain - 80 ml. 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 gastrointestinal tract (adding milk reduces acidity).
It is known that the main element of 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 they are at risk for the development of ailments of blood vessels and heart.
It is important to know: the drink we are considering is contraindicated for hypertensive patients, but hypotensive patients (suffering from low blood pressure) in moderation can be useful. You also need to pay attention to the high acid content. If you use the product every day, then the acidity of the oral cavity, stomach juice and saliva will increase. The enamel of teeth is quickly destroyed.
Harm can be reduced by rinsing the mouth with running water after drinking. You can not drink coffee and those who have gastrointestinal ailments. Lactating and pregnant women should discard this drink. After all, caffeine accumulates in breast milk, has a negative effect on the nervous system of the fetus.
