The origin of instant coffee. The advantages and disadvantages of instant coffee which is better than coffee beans?

Why is instant solution unhealthy?

[let's first talk about the production process]

Freeze-drying is a kind of instant production method which can relatively preserve the flavor of coffee. It is generally used for high-end instant, but the production cost is high. Even if the aroma of coffee is well preserved, the price is unacceptable and the taste is not satisfactory. This is another topic.

The vast majority of instant coffee use spray drying, using high-temperature steam to remove moisture to obtain crystals. The disadvantage is that the aroma of coffee here is like the sour aroma of flowers and fruits, these low molecular weight substances with high volatility are released most quickly at high temperature, followed by aromas of medium molecular weight caramel, nuts, chocolate and so on. Under the continuous high temperature steam drying, the basically good aroma has disappeared.

At this time, you must have a question, then why the instant coffee in the cup has a unique aroma. The answer is a variety of additives, flavors. In particular, the trans fatty acids are more likely to cause cancer. Synthetic chemicals are used for consumption, even in small amounts, but accumulate in the body every day. How long do you think your body will last?

The disadvantages of instant coffee

[let's talk about choosing beans]

Generally speaking, instant coffee will choose Robusta Robusta coffee with high caffeine content and bitter taste. The price is low, the planting capacity is large, and the low altitude planting harvests many times a year. From a commercial point of view, this is a very good choice, especially for the traditional instant process where the aroma is bound to disappear. After all, its aroma comes from essence [laughter].

Of course, some instant producers also use better Arabica beans to make instant coffee. However, from a cost point of view, it is impossible to use high-quality beans. Arabica is not all good beans. As long as they are crops, there will be defects and defective products, and these eliminated defective beans are most likely to be used in instant production. Come to think of it, rotten beans, moldy beans, bacterial-infected beans, beans bitten by worms, and over-fermented smelly beans are all used for instant solubility. don't you feel creepy? Or to put it another way, if you go to the market to buy vegetables, the owner of the grocery store sells rotten vegetables and moldy vegetables, will you buy them and eat them at home? God knows what will happen after eating.

After reading the defective beans in the picture, do you feel that the cup of instant in your hand is a little bad?
