Appearance characteristics and growth form of coffee beans

Coffee beans are one of the most common foods in our daily lives. They have unique appearance characteristics and growth forms. This article will discuss the appearance, color, size, and growth process of coffee beans.

Appearance characteristics

First, let's take a look at the appearance of coffee beans. Generally speaking, mature coffee beans are oval or oblate, and have a depression called the "back ridge". This back ridge is caused by the contraction of the skin during the development of the fruit. In addition, there are small protrusions on both sides of the back ridge, called "naked eyes". These protrusions may vary on coffee beans of different varieties and origins.

In addition, before being processed, coffee beans are usually wrapped in a red or yellow peel. This peel is very hard and can protect the seeds inside from damage. Of course, the peel will be removed during processing.

color

The color of coffee beans is also one of their appearance characteristics. Generally speaking, mature coffee beans appear dark brown or black brown. This is because during the development of the fruit, the seeds inside gradually turn dark brown and produce many organic compounds.

However, it should be noted that in some special cases, coffee beans may appear in other colors. For example, coffee beans picked before they are fully ripe may appear green or light yellow. During the roasting process, coffee beans will become darker due to the high temperature.

size

In addition to appearance and color, coffee beans also come in different sizes. Generally speaking, large varieties are usually rounder and relatively large, while small varieties are relatively smaller and may be flatter in shape.

In addition, the same coffee fruit may contain coffee beans of different sizes. This depends on factors such as nutrient allocation during fruit development and seed growth rate.

Growth form

The growth process of coffee beans can be divided into several stages. The first is the seed germination stage, when the seeds begin to germinate under suitable temperature and humidity conditions and form seedlings. Then comes the seedling stage, when the seedlings gradually grow leaves and carry out photosynthesis.

This is followed by the vegetative stage, during which the plant continues to grow and branch, and finally the flowering and fruiting stage, during which the plant produces small white or light pink flowers and fruits.

It should be noted that the growth morphology of coffee beans may vary under different varieties and environmental conditions. For example, coffee beans grown at high altitudes are usually shorter and have smaller leaves, while those grown at low altitudes are relatively taller.

Summarize

In summary, coffee beans have unique appearance characteristics and growth forms. By observing their appearance, color, size, and understanding their growth process, we can better understand the mysteries hidden behind this delicious food.
