Dark chocolate is a form of chocolate containing only cocoa solids, cocoa butter and sugar. Dark chocolate without added sweetener is known as bitter chocolate [3] or unsweetened chocolate. [4] As with the other two main types of chocolate (milk and white), dark chocolate is used for chocolate bars or as a coating in confectionery.

History

Chocolate is made from the seeds of the tropical Theobroma cacao tree. Chocolate has been consumed over centuries. [5] It may have been developed around 1500 BC [6] in Central and South America as a drink by the Olmecs. [7] Later, it was also made into a drink by the Mayan peoples for ceremonial purposes. [7] [8] They would add honey and cane sugar to make it sweeter, and other additional flavorings as a hot beverage. [7] [9]

Spanish explorers encountered chocolate in the early 1500s and introduced it to Spain. [7] In the late 1600s, milk was also added to the dark chocolate beverage by Hans Sloane, who resided in Jamaica at the time. [5] Chocolate was finally made into a solid form in the 18th century and was mass-produced in the 19th century, with several innovations, in particular by Coenraad Johannes van Houten [7] [10] and Rodolphe Lindt, who invented a machine to mix and aerate chocolate, giving it a smooth texture. [11]

In the late 19th century, Daniel Peter and Henri Nestlé manufactured milk chocolate which became commonly favored. [7] As a consequence, the term dark chocolate was coined to distinguish the traditional chocolate from the new form. In the late 20th century, demand for dark chocolate increased. [5] [7]

Nutrition

Nutrients in dark chocolate include 46% carbohydrates, 43% fats, 8% protein, and 1% water (table). In a 100-gram (3+12-ounce) reference serving, dark chocolate provides 2,500 kilojoules (600 kilocalories) of food energy and is a rich source (defined as more than 20% of the Daily Value, DV) of several dietary minerals, such as iron, copper, manganese, magnesium, phosphorus, and zinc.

As of 2018, high-quality clinical research has not been conducted to evaluate the effects of compounds found in cocoa on physiological outcomes, such as blood pressure, for which only small (1–2 mmHg) changes resulted from short-term consumption of chocolate up to 105 grams and 670 milligrams of flavonols per day. [12] Flavanols found in dark chocolate include the monomers catechin and epicatechin, and (to a lesser extent) the polymeric procyanidins, which remain under laboratory research. [12]

Metal content

Chocolate, particularly dark chocolate, may contain appreciable levels of toxic heavy metals, such as cadmium, which may be present naturally in the soil of cocoa plantations. [13] For products containing over 50% cocoa, the European Commission has set a limit for cadmium of 0.8 mg/kg, while for chocolate containing between 30%–50% cocoa, the limit is 0.3 mg/kg. [13] The state of California recommends a maximum daily intake of 4.1 micrograms of cadmium. [14]

According to a Consumer Reports study in 2022, several dark chocolate products were found to contain high levels of lead and cadmium when compared against California's maximum allowable daily dose levels. [15]

<span class="mw-page-title-main">Chocolate</span> Food produced from cacao seeds

Chocolate, or cocoa, is a food made from roasted and ground cacao seed kernels that is available as a liquid, solid, or paste, either on its own or as a flavoring agent in other foods. Cacao has been consumed in some form for at least 5,300 years starting with the Mayo-Chinchipe culture in what is present-day Ecuador. Later Mesoamerican civilizations also consumed chocolate beverages before being introduced to Europe in the 16th century.

<span class="mw-page-title-main">Chocolate milk</span> Sweetened chocolate-flavoured milk

Chocolate milk is a type of flavoured milk made by mixing cocoa solids with milk. It is a food pairing in which the milk's mouthfeel masks the dietary fibres of the cocoa solids.

<span class="mw-page-title-main">Buttermilk</span> Fermented dairy drink

Buttermilk is a fermented dairy drink. Traditionally, it was the liquid left behind after churning butter out of cultured cream. As most modern butter in Western countries is not made with cultured cream but uncultured sweet cream, most modern buttermilk in Western countries is cultured separately. It is common in warm climates where unrefrigerated milk sours quickly.

<span class="mw-page-title-main">Potassium in biology</span> Use of Potassium by organisms

Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. Potassium is necessary for the function of all living cells, and is thus present in all plant and animal tissues. It is found in especially high concentrations within plant cells, and in a mixed diet, it is most highly concentrated in fruits. The high concentration of potassium in plants, associated with comparatively very low amounts of sodium there, historically resulted in potassium first being isolated from the ashes of plants (potash), which in turn gave the element its modern name. The high concentration of potassium in plants means that heavy crop production rapidly depletes soils of potassium, and agricultural fertilizers consume 93% of the potassium chemical production of the modern world economy.

<span class="mw-page-title-main">Dutch process cocoa</span> Cocoa that has been treated with an alkalizing agent

Dutch processed cocoa, Dutch cocoa, or alkalized cocoa, is cocoa solids that have been treated with an alkalizing agent to reduce the natural acidity of cocoa, giving it a less bitter taste compared to "natural cocoa" extracted with the Broma process. It forms the basis for much of modern chocolate, and is used in ice cream, hot chocolate, and baking.

<span class="mw-page-title-main">Chocoholic</span> Person who craves chocolate

A chocoholic is a person who craves or compulsively consumes chocolate. The word "chocoholic" was first used in 1961, according to Merriam-Webster. It is a portmanteau of "chocolate" and "alcoholic". The term is used loosely or humorously to describe a person who is inordinately fond of chocolate; however, there is medical evidence to support the existence of actual addiction to chocolate. Psychoactive constituents of chocolate that trigger a ‘feel-good’ reaction for the consumer include tryptophan and phenylethylamine, which may contribute to cravings and addiction-like responses, particularly in people with specific genetic alleles. The quantity of sugars used in chocolate confections also impacts the psychoactive effects of chocolate.

White chocolate is a confectionery typically made of sugar, milk, and cocoa butter, but no cocoa solids. It is pale ivory in color, and lacks many of the compounds found in milk, dark, and other chocolates. It is solid at room temperature because the melting point of cocoa butter, the only white cocoa bean component, is 35 °C (95 °F).

Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fatty component of the bean, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 46% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the dry solids with a small remaining amount of cocoa butter. Untreated cocoa powder is bitter and acidic. Dutch process cocoa has been treated with an alkali to neutralize the acid.
