What on earth is instant coffee? Should we drink instant coffee or raw bean coffee?

As early as 1890, the New Zealander David Strang invented the instant technology and applied for a patent. After that, George Washington invented the technology for mass production of instant coffee and brought it to market in 1910. In 1938, in order to deal with the surplus of coffee beans, the Brazilian government and Nestle jointly improved their production technology, especially by adding the same amount of soluble carbohydrates to improve the flavor before drying, making Nestl é a leading brand in the instant coffee industry. In the 1980s, Maxwell and Nestle coffee successively entered the Chinese market, and the instant coffee of the two giants brought the first coffee enlightenment to China.

The production process of instant coffee mainly includes the following parts.

1. Pretreatment: removing impurities from coffee raw materials

two。 Roasting: the substances in coffee beans undergo complex physical and chemical reactions to form unique coffee aroma substances.

3. Grinding: grind cooked beans into powder

4. Extraction: to extract the soluble components of coffee into water at a certain temperature and pressure.

5. Concentration-drying: forming process to get instant coffee powder

Throughout this production method, it can be said to be a great innovation, which greatly simplified the previous complex coffee brewing process, made coffee as a simple and easy drink quickly popular, and directly led to the first wave of coffee in the world.

(the second wave of coffee is dominated by Starbucks espresso)

(the third wave of coffee is dominated by boutique cafes.)

How can I get instant coffee?

Whether you drink two-in-one or three-in-one instant coffee, they are all products of science.

When we come to the instant coffee factory, we will see a large vat of coffee liquid that is ready to be made into instant powder. the process is very simple, just dehydration. When the water in the coffee liquid is removed, it is the instant powder that everyone scoops out of the coffee can. That is, the soluble powder retains the coffee substance that is soluble in water.

The procedure of dehydration can be divided into the following two kinds: freeze drying and spray drying.

It should be noted that some of the substances in coffee are lost during processing, especially caffeine and aroma molecules. Even the quality of coffee powder has a lot to do with the drying process. Some manufacturers even add substances to fill these lost flavors.
