What is the Nescafe leader doing right on the trillion dollar coffee track?
In Nestlé's Greater China region, where sales exceeded $40 billion last year, the iconic coffee business is running at a new pace, and freeze-dried coffee is providing the "fuel" for it.
According to data, the category of freeze-dried coffee was pioneered by Nestlé and an average of 400 cups are consumed every second worldwide. In a market where more and more consumers are returning to the "early C's and late A's", how is Nestlé seizing the opportunity to continue to grow its freeze-dried coffee business, and how is this long-established category going to continue to win the growing coffee market?
What is freeze-dried coffee?
Freeze dried coffee is a coffee product that is frozen to below -40°C and the water is removed in a vacuum environment. As all the water has been removed from the coffee, it can be stored under vacuum for up to 25 years.
The product can therefore be stored for a long time and can be restored to a coffee drink by simply adding hot water.
What is the mechanism of vacuum freeze dried coffee technology?
According to the thermodynamic phase equilibrium theory, the temperature of the three-phase point of water (gas, liquid and solid coexist) is 0.0098°C and the pressure is 4.579mmHg.
As shown in Figure 1, in the process of phase change of water, when. When the pressure is lower than the three-phase point pressure, the solid ice can sublimate directly to gaseous water vapour and escape without undergoing conversion to liquid water.
Why is freeze dried coffee gaining market share over traditional spray coffee?
Compared to traditional coffee made with spray technology, coffee produced with low-temperature freeze-drying technology can retain the maximum nutrient content of coffee and
It has a rich, full-bodied flavour and is easy to brew out; secondly, it has a very long shelf life and can be kept for a long time without deterioration
It is easy to carry and can be restored to a delicious coffee drink by simply adding hot water.
What is the production process of freeze-dried coffee?
1. Pre-treatment: screening, cleaning
2. Roasting
3. Grinding: to improve the extraction efficiency, the roasted coffee beans are ground into a certain particle size
4. Extraction: Under a certain temperature and pressure, the active ingredients are extracted into water
5. Concentration: through vacuum concentration, the concentration of coffee is increased at a lower temperature (i.e. the water is removed from the liquid coffee, which facilitates subsequent drying and increases production efficiency)
6. Drying: As the aromatic substances of coffee are very heat-sensitive, they are very volatile at higher drying temperatures (in fact, they are already volatile in the previous extraction and concentration processes), which is the main reason why instant coffee is often not as aromatic as fried and boiled coffee. But our vacuum freeze drying technology can solve this problem perfectly
Firstly, the coffee concentrate is frozen at a low temperature (-40°C), where the water is frozen into tiny ice crystals, and then slowly heated and sublimated under high vacuum conditions (the heating temperature will not exceed 35°C), through this low humidity drying method, the aromatic substances in the coffee (i.e. heat-sensitive substances) are well preserved, so the aroma of freeze-dried coffee is rich and pure.
