WHO INVENTED CHOCOLATE?
Chocolate is one of the world's best-known treats, yet few people know that its origins go back thousands of years. It was the ancient Maya and Aztecs who first discovered the magical and aphrodisiac properties of cocoa beans, which they began to use as a form of currency and to prepare a bitter, spiced drink called xocolatl, reserved for sacred rituals.
For centuries, cocoa remained a secret jealously guarded by the Mesoamerican peoples, until the Spanish brought it to Europe in the 16th century, making it the exclusive preserve of Spain's most refined courts. In the 17th century, cocoa reached Italy too, sparking a genuine craze! Italians grew so passionate about this food that, in major cities such as Rome and Florence, emporiums sprang up where people could enjoy this precious beverage.
However, chocolate as we know it today, sweet and creamy, was invented much later, in the 19th century, thanks to the Dutch chemist Coenraad Johannes van Houten. In 1828, van Houten patented an inexpensive method for separating cocoa butter from the mass of roasted cocoa, obtaining a powder that could be mixed with liquids to create the famous beverage: this process, known as Dutch processing, made chocolate far easier to produce and to consume. Van Houten is also credited with inventing a hydraulic press that reduced the cocoa butter content of the roasted mass, creating a “cake” that could be ground into cocoa powder: this paved the way for the production of chocolate and of new related products, such as the first chocolate bar, made by the Fry family in 1847.
Thanks to van Houten's inventions, chocolate became far more accessible and popular, marking the beginning of a new era for this food beloved all over the world.
A food with aphrodisiac properties
For centuries, chocolate — and dark chocolate in particular — has been considered a powerful natural aphrodisiac: according to legend, the Aztec emperor Montezuma drank 50 cups of xocoatl a day, the ancestor of chocolate, to keep his sexual reputation alive. But is that really the case? Let's see what science says:
- Chocolate contains phenylethylamine (PEA), a chemical released in the brain when a person falls in love. PEA stimulates the formation of endorphins, the happiness molecules responsible for the state of euphoria and pleasure.
- Cocoa raises levels of serotonin, the good-mood hormone, which also promotes sexual arousal and desire.
- Chocolate fosters the mental chemistry of love, acting on the mechanisms of satisfaction and pleasure thanks to anandamide, the molecule of bliss, found only in cocoa.
- Cocoa improves vasodilation thanks to nitric oxide, boosting the flow of blood and oxygen to every organ, just like Viagra!
So, while not a true aphrodisiac in the strict sense, dark chocolate can help improve mood, circulation and the brain chemistry linked to pleasure and sexual arousal. However, to avoid side effects — especially for those already living with conditions such as diabetes — it is best to limit consumption to small amounts.
But dark chocolate, when eaten in moderation, can also offer several health benefits thanks to the presence of substances such as flavonoids, polyphenols, theobromine and tryptophan:
- Benefits for the heart and cardiovascular system. It reduces insulin resistance, improves endothelial function, lowers blood pressure, helps arteries stay flexible and healthy thanks to antioxidants and, finally, contains theobromine, which has a cardiostimulant effect useful in preventing heart attacks
- Positive effects on mood and the immune system. It contributes to the production of serotonin, the well-being hormone, has a natural antidepressant effect thanks to phenylethylamine, modulates the immune system positively and has anti-inflammatory properties.
- It regulates body-fat levels. It protects against hepatic steatosis (fatty liver), improves insulin resistance in overweight individuals, is rich in antioxidants that reduce the effects of free radicals and contains minerals such as magnesium, phosphorus and potassium.
That said, dark chocolate remains a calorie-rich food, so it should be eaten only in small amounts as part of a balanced diet. What's more, the tannins it contains can stain teeth, so it's important to brush your teeth after eating it!
Not all cocoa is the same
Not all chocolate is the same: there are 3 types of cocoa, each with different properties:
- Accounting for just 0.001% of world production, the Criollo is regarded as the finest and highest-quality cocoa: it has a light colour, a floral aroma and a flavour marked by notes of honey and red berries. The Criollo cocoa is a variety native to the Venezuelan Andes, cultivated since ancient times by pre-Columbian civilisations such as the Maya and the Aztecs; the plant, however, is very delicate and prone to pest attacks, which makes its cultivation a considerable risk for growers, who need very specific environmental conditions.
- The Forastero cocoa accounts for about 85% of global cocoa production, ranking as the world's most widespread variety. Native to the Brazilian Amazon, the Forastero stands out for its very dark colour and its particularly bitter, astringent taste: it is used mainly for cocoa powder, bulk chocolate and other baked goods. Although it contains fewer aromatic substances and more bitter ones such as theobromine, the Forastero cocoa still retains health-beneficial properties thanks to the flavonoids and polyphenols present in cocoa.
- The Trinitario cocoa is a hybrid of the prized Criollo varieties and the more common Forastero ones, and accounts for about 10% of the world's cocoa production. Considered a fine, aromatic variety, the Trinitario has a darker colour than Criollo and a less bitter taste than Forastero. It is grown in various regions of the world such as Peru, Colombia, Ecuador, Tanzania, Madagascar and Venezuela.
How is chocolate made?
The cocoa plants manage to yield one or two harvests a year: the fruits, known as pods or cabosses, are shaped like elongated nuts and hold the beans inside. But how is cocoa obtained from these large beans? Let's find out together!
- Harvesting and fermenting the cocoa beans. The beans are gathered from the pods and fermented for 5–7 days to develop aroma and flavour, then dried in the sun.
- Roasting. The beans are roasted at temperatures between 100–130 °C for 1–2 hours, so that they can develop their aroma and flavour further.
- Shelling and grinding. The roasted beans are shelled to remove the hard husk, then ground in a roller mill that reduces them to a liquid paste called cocoa mass or liquor.
- Pressing. The resulting cocoa mass is pressed to extract the cocoa butter: this yields a solid cake that is ground into cocoa powder.
- Refining and conching. The cocoa liquor is refined and conched for 12–72 hours in a machine that mixes and heats the mass; this step helps develop the aroma and texture further.
- Tempering. Tempering is a crucial stage in the processing of chocolate, which involves heating, cooling and reheating the cocoa mass to achieve a stable crystallisation of the cocoa butter: this process is essential to give chocolate a glossy surface, a firm texture and a consistency that does not flake or crumble. The chocolate is first heated to a temperature between 45–50 °C to melt all the cocoa butter crystals present. It is then cooled to around 27 °C, so that stable cocoa butter crystals can form. Finally, it is reheated to 31–32 °C to melt the unstable crystals and obtain a smooth, glossy mass. This delicate procedure calls for skill and experience on the part of the chocolatier, since temperatures and cooling times must be perfectly calibrated to achieve the desired result. Only well-tempered chocolate can guarantee a velvety texture and a long shelf life, without the risk of turning dull or whitish.
- Forming and cooling. The tempered chocolate is poured into moulds and left to cool to obtain the desired shapes, such as bars or pralines.
Described as a precious gift of the gods, chocolate has journeyed through centuries of history, evolving and adapting to the tastes of every age, to become one of the world's most loved and most consumed treats. Now all you have to do is start tasting, experimenting and letting yourself be enchanted by this extraordinary food, which holds within it the history of entire civilisations.
And chocolate, in all its forms, is far more than a simple sweet: it is a unique sensory experience, a journey into taste, a moment of pure well-being for body and soul.
