If you are one of those who like to get home and pour yourself a coffee quickly and conveniently, then this post is for you.
Freeze-dried and soluble coffee are different, but their preparation is very fast and simple. The final consumer will have access to a delicious cup of coffee by adding a little hot water or milk.
These drinks adapt perfectly to the current rhythm of life since both preparations are instantaneous. Read more to know the difference between them.
Freeze-dried and soluble coffee
The main difference between freeze-dried and soluble coffee lies in how it is processed and obtained.
Soluble coffee is obtained through a coffee concentrate that requires filters and percolators. It undergoes an atomization process, spraying it in a stream of hot, dry air.
The atomization extracts the water from the coffee, and later this liquid is poured into cylinders approximately 15 meters high.
In this way, baristas obtain an irregular and rough-shaped soluble coffee. This process is intense, and the coffee loses aroma and flavor; however, artificial substances are added as aromatic and flavoring substitutes.
Soluble coffee is not new: the product began to be marketed in 1930 and is still one of the market’s favorites today.
Freeze-dried coffee (sublimation)
Freeze-dried coffee is obtained from a sublimation process that transforms the coffee into a fine, quality granulated product.
Sublimation involves changing the solid state (ice) to the gaseous state (vapor) without passing through the liquid form.
A vacuum is generated in a special chamber, where the iced coffee bars are sublimated, turning the solidified water into steam. The coffee is progressively dried to create freeze-dried coffee particles through deep freezing.
The freeze-drying process does not require the application of chemicals, therefore, it is more ecological and healthy. Lyophilization is currently a method of preserving food, medicine, among others.
Some additional practices or techniques can be generated during this procedure, such as freezing, vacuum, and dehydration. Consequently, a dry product emerges that retains its original organoleptic characteristics, for example: aroma, flavor, and taste.
