Fermentation is an important step in processing cocoa beans to make chocolate. In fermentation, beans that have been removed from their pods are put together in close proximity. Yeasts , lactic acid bacteria and acetic acid bacteria break down pulp surrounding the beans and develop flavor precursors within the bean that create chocolate flavors ...
Cocoa powder may have a fat content of about 12%, [101] but this varies significantly. [102] Cocoa butter is used in chocolate bar manufacture, other confectionery, soaps, and cosmetics. [citation needed] Treating with an alkali produces Dutch process cocoa, which is less acidic, darker, and more mellow in flavor than untreated cocoa. Regular ...
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Chocolate before conching has an uneven and gritty texture. The conching process produces cocoa and sugar particles smaller than the tongue can detect (typically around 20 μm) and reduces rough edges, hence the smooth feel in the mouth. The length of the conching process determines the final smoothness and quality of the chocolate.
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. [1] It also promotes flavor development through frictional heat, release of volatiles and acids, and oxidation.
Cocoa beans and cocoa harvest processing. Ghana's cocoa production grew an average of 16 per cent between 2000 and 2003. [18] Cocoa has a long production cycle, far longer than many other tropical crops, and new hybrid varieties need over five years to come into production, and a further 10 to 15 years for the tree to reach its full bearing potential.
The crop is grown in Ivory Coast mostly by smallholder farmers planting on 1 to 3 hectares. [10] The pods containing the beans are harvested when a sufficient number are ripe, opened to separate the seeds and pulp from the outer rind, and the seeds and pulp are usually allowed to ferment somewhere on the farm, before the seeds are dried in a central location.
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, and ...
