From cacao to chocolate

Từ cacao to chocolate

The Cacao Bean

Ca cao originates from the cacao tree in wet tropical countries. The cocoa production territories are concentrated around the equator e.g.: Ivory Coast, Ecuador, Brazil Ghana and Zaire.

Các cocoa pod is 15-30 cm long and has a red or yellow color. Each pod contains 25-50 seeds or beans. Cacao trees produce pods throughout the year, but large harvests occur twice annually and may take weeks to complete.

Harvesting

Ở đó are no machines for harvesting cacao. Instead, workers must harvest the pods by hand, using short, hooked blades mounted on long poles to reach the highest hoa quả. The pods’ thick shells are then opened and the pulp-covered cacao beans are scooped out.

The Fermenting

Các beans are then fermented in trays or heaps on the ground and covered with lá chuối. For the next three to nine days, the seeds will ferment like wine, giving the seed their chocolate flavor. During fermentation, the beans turn a rich, deep brown. Fermented seeds are then dried in the sun, or some use special air drying equipment, to prevent mold growth. The cocoa beans are then packed into burlap sacks and shopped to chocolate and cocoa producing factories khắp thế giới. One of the larges chocolate producers is Callebaut in Nước Bỉ.

Cleaning and Roasting

Các beans of different origin are sorted and then cleaned and roasted, which is the key to excellent chocolate flavor. The seed loses much of its moisture and turns a deep brown color. The roasting also simplified the separation of shell and nibs.

Winnowing and Crushing

Tiếp theo the roasting process, the beans go through a machine called a winnower, which removes the outer hulls and separates the nibs of the beans by size. The nibs are the basic product used for chocolate production.

Các nibs are then milled—crushed by heavy steel discs. This process grinds them into a thick paste called chocolate liquor.

Một vài of the chocolate liquor is placed to large presses, which squeezes out the cocoa bơ. This fatty, yellow substance can be added to dark or milk chocolates, used as the basis for white chocolate, or used in cosmetics and medicine. Các remaining solid cocoa is crushed, ground and finely sifted into cocoa powder—the product used in beverages, cooking, and baking.

Blending

Ca cao paste, cocoa butter, sugar and milk are the four basic ingredients for making sô cô la. By blending these ingredients, with specific recipes, the basis of every chocolate product is made: dark chocolate, milk chocolate, and white sô cô la. The extra cocoa butter keeps the chocolate solid at room nhiệt độ. This explains why chocolate doesn’t spoil—and why it melts in the warmth of your mouth.

Refining and Conching

Kế tiếp, the chocolate mixture goes through a series of steel rollers which refines the chocolate and breaks down the tiny particles of cocoa, and sugar. The refined chocolate paste is poured into a vat in which a large heavy roller kneads, blends, and grinds the mixture.

Trong this process, called “conching”, the paste is refined again by agitating, heating and mixing, giving the chocolate a silky texture and pure đặc trưng. Aerating the paste allows acids and moisture to evaporate causing the bitter taste to gradually disappear and the flavor is to be fully đã phát triển.

Tempering

Cuối cùng, the refined chocolate is cooled and warmed repeatedly in a process called “tempering. ” This gives chocolate its glossy sheen, and ensures that it will melt properly.

Các finished chocolate is molded and packaged to be used by chocolate manufacturers to create the bars, truffles, and other fine confections that sweeten our life.
