Cocoa bean

The cocoa bean, also known as cocoa or cacao, is the dried and fully fermented seed of Theobroma cacao, the cacao tree. From this bean, we get cocoa solids and cocoa butter, which are used to make chocolate and other treats. Cacao trees grow naturally in the Amazon rainforest and have been important to cultures for thousands of years.

Cacao was first used at least 5,300 years ago by the Mayo-Chinchipe culture in South America. Later, it became a valued part of Mesoamerican cultures, where cacao beans were used as money and in special ceremonies. Today, most cocoa comes from West Africa, with Ivory Coast producing the most.

Cocoa beans aren’t just tasty—they also have healthy substances like phytochemicals, flavanols, and theobromine. It takes about five years for a cacao tree to grow big enough to produce beans, and these trees can live for up to 100 years. As the world loves chocolate more each year, finding ways to grow cocoa safely and sustainably is very important.

Etymology

The word "cocoa" comes from "cacao," which might have been mixed up with the word coco. The original word kakaw(a) has sparked debate about whether it started in the Nahuatl language or a Mixe-Zoquean language.

Long ago, in the 18th century, people called these beans "chocolate nuts," "cocoa nuts," or simply "cocoa." The name "cocoa beans" became popular in the 19th century.

History

The cacao tree, which grows in warm areas near the Equator, has a long and interesting history. It was first grown more than 5,300 years ago in what is now Ecuador by ancient people. Later, it spread to other parts of South America and Mesoamerica, where it was used in special ceremonies and even as money by people like the Maya and Aztecs.

When the Spanish explorers arrived in Mexico, they discovered the local people enjoying a special drink made from cacao beans. They brought this drink, called chocolate, back to Europe, where it became very popular. Today, most of the world’s cacao comes from Africa, especially countries like Ghana and the Ivory Coast.

Varieties

Main article: Types of cocoa beans

Cocoa beans are grouped into three main types: Forastero, Criollo, and Trinitario. Criollo beans have been highly valued for a long time and were originally from South America. When European explorers came, they brought different beans called Forastero from South America, which means “strange” or “foreign.” These are often from West Africa. Trinitario beans are a mix of Criollo and Forastero.

Cultivation

A cocoa pod is about 17 to 20 cm long with a rough, leathery rind filled with sweet, juicy pulp surrounding 30 to 50 large seeds. These seeds start off soft and a pale lavender to dark brownish purple color.

During harvest, the pods are opened to collect the seeds, which are then placed to ferment. This process changes the seeds' color to brown and prepares them for making chocolate. Cacao trees grow in hot, rainy tropical areas near the Equator, and their pods grow directly from the trunk of the tree, making them easier to harvest by hand.

Production

In 2022, the world produced about 5.87 million tonnes of cocoa beans. The country that grew the most cocoa was Ivory Coast, making up about 38% of all the cocoa grown. Other big producers of cocoa beans were Ghana and Indonesia.

Cocoa trading

Cocoa beans are often placed in special bags for shipping and storage, but they can be attacked by pests. To keep the beans safe, people use special seals and low-oxygen containers.

Cocoa beans, butter, and powder are sold in special markets called futures markets. The main markets are in London and New York. These markets help decide the price of cocoa products around the world.

Sustainability

Many countries and groups work together to help make cocoa farming better for people and the environment. They focus on fair pay for farmers, protecting forests, and making sure cocoa comes from places where it’s grown responsibly. For example, some companies and organizations have joined forces to help cocoa farmers earn a good living and protect forests from being cut down.

There are also special labels on cocoa products, like Fairtrade, that show the cocoa was grown in a way that helps farmers and the environment. These labels can mean better farming practices and fairer prices, though not all farmers always benefit equally. Farmers are learning ways to grow cocoa that are better for the land, like using trees to give shade to the cocoa plants, which helps keep the soil healthy and protect wildlife.

Economic effects

Cocoa plays an important role in Nigerian economy, making up a large part of the country's foreign exchange and providing income for farmers. Farmers can grow other fruit trees to supplement their income, especially when cocoa prices change a lot. While growing cocoa in direct sunlight can increase yields for a short time, it can harm the soil over time. Using trees to provide shade helps protect the soil and supports long-term cocoa farming.

People around the world enjoy cocoa in many forms, using over 3 million tons of cocoa beans each year. After harvesting, cocoa beans are processed into different products. The Netherlands is one of the largest processors of cocoa, handling about 13% of the world's supply. Europe and Russia together process about 38% of the world's cocoa. Demand for cocoa has been growing, especially in developing countries where incomes are rising. However, future supply may face challenges due to changes in weather patterns in key cocoa-growing regions.

Chocolate production

Main article: Chocolate § Processing

To make 1 kilogram of chocolate, about 300 to 600 cocoa beans are used. These beans are roasted, cracked, and cleaned to get pieces called nibs. The nibs are then ground into a thick paste called chocolate liquor or cocoa paste. This paste is mixed with cocoa butter, sugar, and sometimes vanilla to make chocolate.

Cocoa powder can have about 12% fat, and cocoa butter is used not just in chocolate bars but also in candies, soaps, and cosmetics. Roasting the beans or nibs helps give chocolate its flavor, with different roasting times and temperatures creating different tastes.

Phytochemicals and research

Cocoa contains many helpful substances called phytochemicals, such as flavanols, procyanidins, and flavonoids. Eating chocolate or cocoa that is rich in flavanols may help lower blood pressure a little bit, especially in the short term. Raw cocoa has the most flavanols, while dark chocolate has some, since cooking can break them down.

Cocoa beans also have a substance called theobromine and a small amount of caffeine—much less than what is found in coffee beans. Theobromine is found in cocoa solids and can dissolve in fat.
