The true color of coffee beans

Coffee beans are one of the most common foods in our daily lives, and their color is also one of the important reference factors when people choose and taste coffee. Coffee beans of different types and processing methods have different color characteristics. The following will introduce some knowledge about the true color of coffee beans.

1. Coffee beans in their original state

In their raw state, coffee beans that have not been processed or roasted appear light green or dark green. This is because they still contain moisture and other chemicals in the ripe but unprocessed process. This color in the raw state is usually completely different from the finished coffee we see and buy in the market.

2. Comparison before and after baking

When roasting, the original dark green color becomes more obvious and gradually turns into yellowish brown, tan or even dark brown. Many chemical reactions occur during this process, the most important and influential of which are the reactions between sugars and amino acids. These reactions lead to changes in the color of coffee beans, and also affect the taste and flavor of coffee beans.

3. Coffee bean roasting degree and color

Different degrees of roasting will make the coffee beans present different colors. Generally speaking, light roasting will make the coffee beans retain more of the original dark green color with a slight yellowish brown. Medium roasting will turn the coffee beans into brown, while dark roasting will turn them into dark brown or even close to black.

4. Effect of pigment oil on color

In some special cases, producers may add certain substances to change or enhance the color of coffee beans. The most common and widely used of these is food-grade dye oil. This oil can easily penetrate the surface of coffee and change its appearance. However, you need to be careful about the presence of such artificial additives when purchasing and tasting.

5. The relationship between coffee bean color and quality

The color of coffee beans does not necessarily directly reflect their quality. Although dark roasted coffee beans are generally considered to have a stronger and more bitter taste, this does not mean that they are high-quality coffee. In fact, everyone has different preferences for taste and flavor, so choosing coffee that suits your taste is the most important thing.

in conclusion

In short, coffee beans will present a variety of colors after being roasted. From dark green in its original state to yellowish brown, brown or even black brown, each color represents a specific degree and flavor characteristics. However, when choosing and purchasing, you need to pay attention to whether there are artificial additives, and understand that there is no necessary connection between color and quality.
