Instant coffee
The truth is that instant coffee does not contain real coffee beans, but only dried coffee flavor solution is the result of a complex brewing process.
Process
Extraction: The process begins by passing the water through a series of full cylinders of ground coffee beans. One reason why the instant coffee is bitter because during the extraction process to be burned because the coffee grounds until the temperature hit 180 ° C. (The optimum temperature is widely agreed, among the fans of coffee, to make coffee is between 90-95 ° C).
Filtration & Concentrations: Solutions of coffee and then filtered to remove unwanted particles before the concentration phase. Here the water is removed from the solution to enhance the taste of coffee. Dehydration: At this stage the coffee solution was converted into dry form.
There are two commonly used methods; Spray Freeze drying and drying. Spray drying method is very complex, but the basic principle is for the spraying of hot air through the coffee solution to evaporate the remaining water. Freeze drying involves the rapid freezing of the coffee solution to the block which was then broken into small particles. These particles are then heated in a vacuum where the ice is vaporized and removed.
Aromatisation: All the different stages and the high temperatures used in it, destroying most of which occur in the natural flavor of coffee. Dried coffee solution, therefore, both boiled and bitter. So to help improve the taste, aroma produced during the various stages of this process is captured and then sprayed dried coffee particles.
If that's not enough to make you switch from a cup of instant coffee to a cup of freshly brewed then you might want to consider that the instant coffee, in most cases, not enough trade. In fact, one might say that the instant coffee industry, which mainly consists of large multinational companies, primarily responsible for coffee farmers receive low prices for their crops.
