What is Whipped Coffee?
If you've forgotten or didn't know this drink existed, let me help you to remember.
This "400 times coffee", first appeared on a Korean entertainment show, and began to take the world by storm. It is very simple but very laborious. The show's practice is to stir 400 times with a spoon with bare hands, the final appearance of light coffee-colored milk froth, so "400 times coffee"!
What is the science behind 400 times coffee?
Instant coffee powder is made from brewed coffee that has undergone a process of concentration and dehydration. When drinking it, coffee can be brewed by simply adding hot water. But in fact, it cannot be completely dissolved in water, its mixture forms a stable colloid, also known as a colloidal dispersion, which is a homogeneous mixture.
The colloid contains two kinds of substances, the dispersed substance is called [dispersion] (micro-fine coffee solid particles) and the other is a continuously distributed substance called [dispersion medium] (water). When stirring, a large amount of air is introduced into the mixture to form bubbles. Normally, the small bubbles will combine to form large bubbles and then burst.
However, very fine coffee particles can be attracted to the bubble surface, surrounding and trapping the bubbles and blocking the surrounding bubbles from combining. As a result, a large number of small bubbles are retained, forming a cloud-like coffee foam.
The technical term (chemically) for this phenomenon is called Pickering stabilization.
Cloud bubble-like coffee foam is also a type of colloid, but it contains air (the substance that is dispersed) and water (the substance that is continuously distributed). The purpose of sugar, when dissolved, increases the viscosity of the mixture and helps stabilize the foam.
Only instant coffee powder will have this effect, ordinary brewed coffee (espresso or hand-brewed), 3-in-1 coffee, matcha powder, and chocolate powder cannot froth because they cannot form a colloid containing solid particles when mixed with water.
Ordinary brewed coffee contains few coffee particles or has a large particle size variation, making it difficult to effectively trap air bubbles compared to instant coffee powder.
