'''Instant coffee''', also known as '''soluble coffee''', '''coffee crystals''', and '''coffee powder''', is a beverage derived from [[Coffee|brewed coffee beans]]. It enables people to quickly prepare hot coffee by adding hot water or milk to the powder or crystals and stirring. Instant coffee is commercially prepared by either freeze-drying or spray drying, after which it can be rehydrated.

==History==
Instant coffee was invented and patented by inventor [[David Strang]] in 1890, with [[Alphonse Allais]], a Frenchman, developing his own method in the same year. High demand during [[World War II]] significantly increased the popularity of the product, which was used as a quick way to ensure coffee was available for soldiers.

==Production==
The production of instant coffee involves multiple steps. First, green, unroasted [[Coffee bean|coffee beans]] are cleaned and sorted. These beans are then roasted and ground. The ground beans are brewed with water to produce a concentrated coffee solution. This solution is then either freeze-dried or spray-dried to remove the water, leaving behind dehydrated crystals of coffee. These crystals can then be packaged and sold as instant coffee.

===Freeze-drying===
In the freeze-drying process, the coffee extract solution is frozen to about -40 degrees Celsius. It is then broken into smaller granules, which are dried in a vacuum with low heat. This process is generally considered to produce instant coffee of a higher quality compared to spray drying.

===Spray-drying===
In the spray-drying process, hot air is used to evaporate the water in the coffee extract. The droplets of coffee extract are sprayed into a hot air stream (180-220 degrees Celsius). As the water evaporates, dried coffee particles are left behind. These particles are then collected and packaged.

==Health==
Instant coffee contains slightly less [[Caffeine|caffeine]] and more [[Acrylamide]] than regular coffee. However, the health implications of these differences are unclear, and more research is needed.
