What Processes Are Used To Make Instant Coffee?
As a coffee lover, you do not necessarily need to turn your nose up at an instant cup of Joe, you just need to know which process to look for to make sure that all of the flavors are still there when you create your instant coffee product.
There are two processes used to make instant coffee, freeze drying and spray drying. Freeze drying is the preferred method because the coffee product is left out so that all of the water naturally evaporates, leaving a coffee concentrate. This concentrate is then frozen, and the ice is taken out of the freeze dried coffee crystals in a process called sublimation. This allows the essential oils to remain in the freeze dried coffee crystals so that your instant cup of Joe is as delicious as ever.
Spray drying also does allow water to evaporate so that a coffee concentrate is formed again, and then this concentrate is placed in a hot air chamber so that the water is evaporated at a high temperature. This leaves coffee crystals at the bottom of the chamber, but the essential oils are zapped from the product because of the high heat that is used.
Keep these facts in mind when looking for premium instant coffee to give you some added convenience during travel, camping, or even baking!

Thanks for the information about spray dried vs freeze dried coffee. We're Coffee Importers, LLC, and considering adding to our fresh roasted, flavored products a type of "instant" coffee. Yet, since we've never been big fans of anything but whole bean coffee we'd like to know more about the different processes for creating an "instant" cup of coffee. Is there anything that may rival freshly roasted, freshly ground and freshly brewed coffee?
Thank you for your comment! Though nothing may beat a freshly roasted, freshly ground, and freshly brewed cup of coffee, methods for creating instant coffee have come a long way. It is recommended to look for instant coffee produced as freeze dried because it will preserve the most natural flavors within the final product. This is a more involved process, but when instant coffee is freeze dried, the frozen water can be removed, so the essential oils of the coffee beans will still remain for a better taste and flavor. Spray dried instant coffee is more compromised and will often strip away the flavors in the coffee because of the temperatures used. For the freshest and best tasting instant coffee, it is best to use freeze-dried instant coffee!
