Dutch process chocolate or Dutched chocolateis chocolate that has been treated with an alkalizing agent to modify its color and give it a milder 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 cocoa, and baking.
Chocolate is a usually sweet, brown food preparation of roasted and ground cacao seeds. It is made in the form of a liquid, paste, or in a block, or used as a flavoring ingredient in other foods. The earliest evidence of use traces to the Olmecs (Mexico), with evidence of chocolate beverages dating to 1900 BC. The majority of Mesoamerican people made chocolate beverages, including the Maya and Aztecs. Indeed, the word "chocolate" is derived from the Classical Nahuatl word chocolātl.
In chemistry, an alkali is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element. An alkali also can be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline is commonly, and alkalescent less often, used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases.
In chocolate making, the Broma process, is a method of extracting cocoa butter from roasted cocoa beans. The Broma process consists of hanging bags of roasted cocoa beans in a very warm room, above the melting point of cocoa butter, and allowing the cocoa butter to drip off the beans, where it is collected. The Dutch process differs from the Broma process in that, after the cocoa butter has been drained off the beans as described above, the beans are then soaked in an alkaline solution to make them chemically neutral.
The Dutch process was developed in the early 19th century by Dutch chocolate maker Coenraad Johannes van Houten, whose father Casparus is responsible for the development of the method of removing fat from cacao beans by hydraulic press around 1828, forming the basis for cocoa powder. These developments greatly expanded the use of chocolate, which had been mostly used as a beverage in Europe until that time.[ citation needed ]
The Netherlands is a country located mainly in Northwestern Europe. The European portion of the Netherlands consists of twelve separate provinces that border Germany to the east, Belgium to the south, and the North Sea to the northwest, with maritime borders in the North Sea with Belgium, Germany and the United Kingdom. Together with three island territories in the Caribbean Sea—Bonaire, Sint Eustatius and Saba— it forms a constituent country of the Kingdom of the Netherlands. The official language is Dutch, but a secondary official language in the province of Friesland is West Frisian.
Coenraad Johannes van Houten 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 from roasted cocoa beans, though this was in fact his father's invention.
Cocoa butter, also called theobroma oil, is a pale-yellow, edible vegetable fat extracted from the cocoa bean. It is used to make chocolate, as well as some ointments, toiletries, and pharmaceuticals. Cocoa butter has a cocoa flavor and aroma. Its melting point is just below human body temperature.
Dutch processed cocoa has a neutral pH, and is not acidic like natural cocoa, so in recipes that use baking soda as the leavening agent—which relies on the acidity of the cocoa to activate it—buttermilk, yoghurt or sour milk should be substituted for the milk in the recipe, or a dash of cream of tartar can be used to provide some acidity in the batter. There is no need to add acidity when Dutch process cocoa is used in recipes that use baking powder instead of soda (UK: "bicarb") for leavening.
In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, basic solutions have a higher pH. At room temperature, pure water is neither acidic nor basic and has a pH of 7.
A leaven, often called a leavening agent, is any one of a number of substances used in doughs and batters that cause a foaming action that lightens and softens the mixture. An alternative or supplement to leavening agents is mechanical action by which air is incorporated. Leavening agents can be biological or synthetic chemical compounds. The gas produced is often carbon dioxide, or occasionally hydrogen.
Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid-base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. The first single-acting baking powder was developed by food manufacturer Alfred Bird in England in 1843. The first double-acting baking powder was developed by Eben Norton Horsford in America in the 1860s.
The Dutch process:
An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).
Compared to other processes, Dutch process chocolate contains lower amounts of flavonols (antioxidants). [ citation needed ]The effect this has on nutritional value is disputed. Professor Dr. Irmgard Bitsch of the Institut für Ernährungswissenschaft, Justus-Liebig-University Giessen claims that the reduction of antioxidants due to the process is not significant and enough polyphenols and procyanids remain in the cocoa. One study determined that 60% of natural cocoa's original antioxidants were destroyed by light dutching and 90% were destroyed by heavy dutching. A new study found "...protection against synaptic deficits by Lavado cocoa extract, but not Dutched cocoa extract... since much of the polyphenol content is lost by the high alkalinity in the Dutching process." However, natural cocoa has such high levels of antioxidants that even a 60% reduction leaves it high on the list of antioxidant-rich foods.
Flavonols are a class of flavonoids that have the 3-hydroxyflavone backbone. Their diversity stems from the different positions of the phenolic -OH groups. They are distinct from flavanols such as catechin, another class of flavonoids.

Giessen, spelled Gießen in German (German pronunciation: [ˈɡiːsn̩]], is a town in the German federal state of Hesse, capital of both the district of Giessen and the administrative region of Giessen. The population is approximately 86,000, with roughly 24,000 university students.
Bread is a staple food prepared from a dough of flour and water, usually by baking. Throughout recorded history it has been a prominent food in large parts of the world and is one of the oldest man-made foods, having been of significant importance since the dawn of agriculture.
Nutella is a brand of sweetened hazelnut cocoa spread. Nutella is manufactured by the Italian chocolate and confectionery company Ferrero. It was first introduced to the European public in 1964, although it was first formulated the year prior.
Cake is a form of sweet dessert that is typically baked. In their oldest forms, cakes were modifications of breads, but cakes now cover a wide range of preparations that can be simple or elaborate, and that share features with other desserts such as pastries, meringues, custards, and pies.
A chocolate chip cookie is a drop cookie that originated in the United States and features chocolate chips or chocolate morsels as its distinguishing ingredient. Circa 1938, Ruth Graves Wakefield added chopped up bits from a Nestlé semi-sweet chocolate bar into a cookie.
Cheesecake is a sweet dessert consisting of one or more layers. The main, and thickest layer, consists of a mixture of soft, fresh cheese, eggs, and sugar. If there is a bottom layer, it often consists of a crust or base made from crushed cookies, graham crackers, pastry, or sometimes sponge cake. It may be baked or unbaked.
Devil's food cake is a moist, airy, rich chocolate layer cake. It is considered a counterpart to the white or yellow angel food cake. Because of differing recipes and changing ingredient availability over the course of the 20th century, it is difficult to precisely qualify what distinguishes devil's food from the more standard chocolate cake, though it traditionally has more chocolate than a regular chocolate cake, making it darker. The cake is usually paired with a rich chocolate frosting.
"On hot chocolate: It flatters you for a while, it warms you for an instant; then all of a sudden, it kindles a mortal fever in you." — Marie Marquise de Sévigné
Red velvet cake is traditionally a red, red-brown, mahogany, maroon, crimson or scarlet colored chocolate layer cake, layered with white cream cheese or ermine icing. Common modern red velvet cake is made with red dye; the red color was originally due to non-Dutched, anthocyanin-rich cocoa.
Quick bread is any bread leavened with leavening agents other than yeast or eggs. An advantage of quick breads is their ability to be prepared quickly and reliably, without requiring the time-consuming skilled labor and the climate control needed for traditional yeast breads.
Maltesers are a British confectionery product manufactured by Mars, Incorporated. Maltesers consist of a spheroid malted milk centre surrounded by milk chocolate. Maltesers are sold in a variety of packaging, including plastic bags, larger cardboard boxes and tubes, and plastic buckets. They also have medium-sized "teasers" in Celebrations boxes. Maltesers are also one of the types of chocolate included in Mars's Revels assortment.
Chocolate syrup is a sweet, chocolate-flavored condiment. It is often used as a topping or dessert sauce for various desserts, such as ice cream, or mixed with milk to make chocolate milk or blended with milk and ice cream to make a chocolate milkshake. Chocolate syrup is sold in a variety of consistencies, ranging from a thin liquid that can be drizzled from a bottle to a thick sauce that needs to be spooned onto the dessert item.
Dry cocoa powder is the constituent of cocoa beans remaining after cocoa butter, the fat component, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 50% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the solids sold as an end product.
Chocolate is a range of foods derived from cocoa (cacao), mixed with fat and finely powdered sugar to produce a solid confectionery. There are several types of chocolate, classified according to the proportion of cocoa used in a particular formulation.
Chocolate ice cream is ice cream with natural or artificial chocolate flavoring. Chocolate is the second most common flavor of ice cream in the United States, after vanilla.
