Have you ever wondered about the possibility of freeze-drying your favorite edibles? This cutting-edge preservation technique offers a unique way to extend the shelf life of food items while maintaining their flavor and nutritional value.
Nescafe, Bru etc. are instant coffee. They are made by first brewing the ground coffee and then the strained(removal of ground coffee) coffee is concentrated into a very thick liquid. This thick liquid is nothing but concentrated brewed coffee. It is then freeze dried so that it looses the water content without loosing the aroma. That’s why instant coffee is completely soluble. Also you might have noticed that we require just 1 teaspoon of instant coffee to make 1 cup of coffee but you need at least one and half tablespoon of ground coffee to make 1 cup.
You can make instant coffee at home also(but it wont taste like coffee at all)…just brew coffee and put the coffee in sunlight. You will find a layer of powder at the bottom when all the water has evaporated. This powder is nothing but instant coffee.
Freeze drying locks in all the aroma but it is carried out at -40 degree Celsius and uses a principle called sublimation(Sublimation (phase transition)). This method locks the flavours in.
There is another method called spray drying which is cheaper and more common. But the coffee made in this process is cheap and not that tasty.
Both Bru gold and Nescafe classic are spray dried. However, Bru Exotica and Nescafe Gold are freeze dried and taste better. They are more expensive also.

Process of Freeze Drying
Freeze drying, also known as lyophilization, is a process that involves removing moisture from food items through a combination of freezing and drying. The process begins by freezing the food product at very low temperatures, typically below -40°C. This freezing step helps preserve the structure of the food and prevents ice crystals from forming within the product.
Once the food is frozen, it is placed in a vacuum chamber where the pressure is lowered to create a low-pressure environment. The next step involves slowly increasing the temperature in the chamber, which causes the frozen water in the food to sublimate directly from a solid to a gas. This sublimation process removes the moisture from the food without causing it to thaw.
During freeze drying, the food goes through three main stages: freezing, primary drying, and secondary drying. In the primary drying stage, most of the water is removed from the food, while the secondary drying stage removes any remaining moisture to ensure the product’s stability and shelf life.
Freeze drying is a popular method for preserving food because it retains the food’s original taste, texture, and nutritional value. It is commonly used to preserve fruits, vegetables, meats, and other perishable items. Freeze-dried foods are lightweight, easy to store, and have a long shelf life, making them ideal for camping, backpacking, and emergency preparedness.
In conclusion, freeze drying is a sophisticated process that removes moisture from food items while preserving their quality and nutrients. By carefully controlling the temperature and pressure, freeze drying allows for the long-term preservation of a wide variety of foods without compromising their taste or texture.
