Instant coffee
Instant coffee is a type of coffee beverage made from dehydrated coffee extract. This extract is obtained by brewing ground coffee beans, similar to regular coffee, but in a more concentrated form. After brewing, water is removed from the extract to produce dry fragments or powder, which dissolve upon adding water. There are two primary methods for making instant coffee: spray drying and freeze drying, both of which preserve the high quality, aroma, and flavor of the coffee. The most popular method for preparing instant coffee involves adding one teaspoon of powder or granules to a cup of hot water. The strength of the coffee can be easily adjusted by adding more or less powder to the cup.
Composition of components in soluble coffee
Similar to regular coffee, soluble coffee contains many powerful antioxidants and nutrients that have a beneficial effect on our health. It may, among other things, contribute to improved mental health and prevent the development of type 2 diabetes. Comparing the elements in soluble and natural coffee, it turns out that dissolved coffee contains more health-friendly ingredients (e.g. calcium, magnesium, zinc, manganese) as well as heavy metals (e.g. aluminum, nickel). In addition, a standard cup of soluble coffee contains only 4 calories. Caffeine is the most commonly used stimulant worldwide, improving brain function and metabolism. Coffee is its main source. However, soluble coffee usually contains less caffeine than regular coffee, with a range of 30-90 mg per cup compared to 70-140 mg in a cup of regular coffee. An excessively high dose of caffeine can cause restlessness, sleep disturbances, stomach discomfort, tremors, and rapid heartbeat, so soluble coffee may be a good choice for individuals who are sensitive to caffeine.
Diverse consequences of consuming soluble coffee
Acrylamide is a well-known compound that can cause cancer and is produced during thermal processes as a by-product of the Maillard reaction. It is produced, among other things, during the roasting of coffee beans. Dissolved coffee may contain several times more acrylamides than regular coffee. Excessive exposure to this substance can damage the nervous system and increase the risk of cancer. However, if your daily diet does not provide high doses of acrylamide (e.g. fries, tea), consuming soluble coffee should not cause concerns about acrylamide exposure. Soluble coffee also contains much more oxalic acid than natural coffee, which binds with metals and can reduce their absorption. Therefore, soluble coffee is not recommended for people with kidney problems.
The finest soluble coffee solution
Generally, the quality of soluble coffee is extremely difficult to evaluate. Both the caffeine content, health benefits, and the proportion of unwanted ingredients depend on many factors, starting with the beans, through the roasting process and brewing of coffee. Coffee with one expiration date, from one producer to another, can vary twice as much in caffeine content. Given these factors, the drying process itself has little impact on the coffee we consume - although it is always a good idea to choose freeze-dried coffee. Freeze-drying is a process that involves freezing the product and then sublimating the water. During this process, no high temperatures are used, which are one of the most important factors influencing the properties of food, so freeze-drying is the gentlest method of coffee drying. There are several freeze-dried coffee varieties available on the market, including Jacobs Kronung, Tchibo Family, Tchibo Exclusive, Tchibo For Black, and Tesco Gold Coffee. In summary, if soluble coffee tastes as good as natural coffee, there is no reason to give it up, but it is important to maintain moderation. While 1-2 cups a day can have health benefits, a large amount can be harmful.
