Coenraad Johannes Van Houten
Coenraad Johannes van Houten (15 March 1801 – 27 May 1887) was a Dutch chemist and chocolate maker known for the treatment of cocoa mass with alkaline salts to remove the bitter taste and make cocoa solids more water-soluble; the resulting product is still called "Dutch process chocolate". He is also credited with introducing a method for pressing the fat (cocoa butter) from roasted cocoa beans, though this was in fact his father, Casparus van Houten's invention. Father and son van Houten Coenraad Johannes van Houten was the son of Casparus van Houten (1770–1858) and Arnoldina Koster. His father opened a chocolate factory in Amsterdam in 1815, with a mill turned by laborers. At that time, cocoa beans were ground into a fine mass, which could then be mixed with milk to create a chocolate drink or, with addition of sugar, cinnamon, and vanilla, made into cookies. Cocoa press In 1828, Casparus van Houten Sr. (and not his son, who is usually credited) patented an inexpensive m ...

Conching
upright=1.35, Conche (in the Imhoff-Schokoladenmuseum) Conching is a process used in the manufacture of chocolate whereby a surface scraping mixer and agitator, known as a conche, evenly distributes cocoa butter within chocolate and may act as a "polisher" of the particles. It also promotes flavor development through frictional heat, release of volatiles and acids, and oxidation. The name arises from the shape of the vessels initially used which resembled conch shells. When ingredients are mixed in this way, sometimes for up to 78 hours, chocolate can be produced with a mild, rich taste. Lower-quality chocolate is conched for as little as 6 hours. Since the process is so important to the final texture and flavor of chocolate, manufacturers keep the details of their conching process proprietary.McClements, D. Julian ''Understanding and Controlling the Microstructure of Complex Foods'', Woodhead Publishing, 2007, , page 654. There are numerous designs of conches. Food scien ...

Jugendstil
''Jugendstil'' ("Youth Style") was an artistic movement, particularly in the decorative arts, that was influential primarily in Germany and elsewhere in Europe to a lesser extent from about 1895 until about 1910. It was the German counterpart of Art Nouveau. The members of the movement were reacting against the historicism and neo-classicism of the official art and architecture academies. It took its name from the art journal '' Jugend'', founded by the German artist Georg Hirth. It was especially active in the graphic arts and interior decoration. Its major centers of activity were Munich and Weimar and the Darmstadt Artists' Colony founded in Darmstadt in 1901. Important figures of the movement included the Swiss graphic artist Hermann Obrist, Otto Eckmann, and the Belgian architect and decorator Henry van de Velde. In its earlier years, the style was influenced by Modern Style (British Art Nouveau style). It was also influenced by Japanese prints. Later, under the Secessio ...

John Cadbury
John Cadbury (12 August 1801 – 11 May 1889) was a Quaker and English proprietor, tea and coffee trader and founder of Cadbury, the chocolate business based in Birmingham, England. Life John Cadbury was born in Birmingham on 12 August 1801 to Richard Tapper Cadbury and his wife Elizabeth Head. He was from a wealthy Quaker family that moved to the area from the west of England. John went to school at Joseph Crosfields Quaker School at Hartshill, Warwickshire. As a Quaker in the early 19th century, he was not allowed to enter a university, so could not pursue a profession such as medicine or law. Founding Cadbury As Quakers are historically and typically pacifist, a military career was also out of the question. So, like many other Quakers of the time, he turned his energies toward business. After being apprenticed to a tea dealer in Leeds in 1818, he opened a grocer's shop at 93 Bull Street, Birmingham in 1824. He prepared drinking chocolate, and eventually decided to start co ...

Groningen (city)
Groningen (; gos, Grunn or ) is the capital city and main municipality of Groningen province in the Netherlands. The ''capital of the north'', Groningen is the largest place as well as the economic and cultural centre of the northern part of the country; as of December 2021, it had 235,287 inhabitants, making it the sixth largest city/municipality of the Netherlands and the second largest outside the Randstad. Groningen was established more than 950 years ago and gained city rights in 1245. Due to its relatively isolated location from the then successive Dutch centres of power (Utrecht, The Hague, Brussels), Groningen was historically reliant on itself and nearby regions. As a Hanseatic city, it was part of the North German trade network, but later it mainly became a regional market centre. At the height of its power in the 15th century, Groningen could be considered an independent city-state and it remained autonomous until the French era. Today Groningen is a university ci ...

Dutch Chocolate
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 (and darker colour) 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. Alkalizing agents employed vary, but include potassium carbonate (E501), sodium carbonate (E500), and/or sodium hydroxide (E525). Dutching greatly reduces the levels of certain phytochemicals in cocoa. Nutrition History The Dutch process was developed in the early 19th century by Dutch chocolate maker Coenraad Johannes van Houten, whose father Casparus was responsible for the development of the method of removing fat from cocoa beans by hydraulic press around 1828, forming the basis for cocoa powder. These developments greatly expanded the use of cocoa, which had been mostly used as a beverage in Europe ...
