History of Eating Chocolate

History of Eating Chocolate
Having used the presses to remove some of the cocoa butter, the coco powder producers were left trying to find a market for this fat.

This was solved by confectioners finding that eating chocolate could be produced by adding it to a milled mixture of sugar and cocoa nibs.

Only the sugar and cocoa nibs were milled and mixed together they would produce a hard crumbly material.

Adding the extra at enabled all the solid particles to be coated with fat and thus form the hard uniform bar that we know today which will melt smoothly in the mouth.

Almost twenty years after the invention of the press, in 1847, the first British factory to produce a plain eating chocolate was established in Bristol in the UK by Joseph Fry.

With the development of eating chocolate the demand for cocoa greatly increased. Initially much of the cocoa came from the Americas.

The first cocoa plantation in Bahia in Brazil was established in 1746.

The chocolate made by Fry was initially a plain block and it was only in 1876 that the first milk chocolate was made by Daniel Pater in Switzerland.

Chocolate can not contain much moisture, because water reacts with the sugar and turns melted chocolate into a paste rather than a smoothly flowing liquid.

He was helped in this by the recent development of a condensed milk formula by Henri Nestlé. This meant that he had much less water to evaporate.

Also he was able to remove the remaining moisture using relatively cheap water powered machines.

In 1880 Rodolphe Lindt, in his factory in Berne in Switzerland, invented a machine which produced a smoother, better tasting chocolate.

This was known as a conche, because its shape was similar to that of the shell with that name. It consisted of a granite trough, with a roller, normally constructed of the same material, which push the warm liquid chocolate backwards and forwards for several days.

This broke up the agglomerates and some of the larger particles and coated them all with fat.

At the same time moisture and some acidic chemicals were evaporated into the air, producing a smoother, less astringent tasting chocolate.

Chocolate Processing

Chocolate Processing
Although it is not intended to describe in detail the many specialized techniques used in chocolate making, certain steps in the process are critical in determining both quality and cost of the finished goods.

Whole beans are roasted for a few minutes in order first to develop their flavor and second to loosen the shells form the nibs.

After passing though cracking rolls, the nib and shell are separated in a winnower.

The nib is then ground; the heat produced in the process is sufficient to melt the cocoa butter and this results in cocoa “liquor” in which fine cocoa particles are dispersed in a continuous fat phase.

Some of the liquor will go straight to chocolate making.

The rest will go though hydraulic presses that reduce the butter content of the cocoa form its level of about 50% to a level of 20% or lower.

The press-cake will subsequently be pulverized for cocoa powder, and the expressed cocoa butter go to chocolate making.
