So you’re wondering “How is Chocolate Made in Factories?” Then read on to learn more about the process, ingredients, quality standards, and artificial flavorings. Then, you’ll know how your favorite confectionery is made. We’ll take a look at some of the most common methods and the actual equipment used. You can even see the machines in action and get a glimpse of how your favorite confectionery is made!


The cocoa beans used in making chocolate are first roasted and then graded. They are then packed into sacks or containers, and then sent on a ship to a chocolate factory. From there, chocolate is made by blending beans from various estates and origins, or keeping the cacao pure and making single-origin chocolate. After the beans are roasted, they are separated from the shell and nibs. The finished product is then packaged and shipped to stores and other chocolate makers.

Roasting the cocoa bean is one of the first steps in chocolate production. Cocoa beans are roasted at high temperatures between 120 to 140 degrees Celsius, which is important for Maillard reactions, which form the flavor and aroma. The roasting process also decontaminates the cocoa bean by removing unwanted components. This process also helps in developing the chocolate’s distinctive flavor. In the second phase, the chocolate mass is conched and cooled, and a complex chemical reaction takes place to produce the chocolate.

Production process

The Production Process of Chocolate in a Factory begins with tempering chocolate. The chocolate is heated to 31 degrees Celsius to make it firm. Excessive heating destroys the temper of chocolate. To maintain the luster and crisp texture, the chocolate is cooled slowly to prevent it from becoming crumbly or brittle. During the next stages, the chocolate is molded and packaged according to customer orders. In a chocolate factory, tempering takes place at different stages of the process.

Chocolate is then tempered and then passed through vibrating screens. This process removes large particles from the chocolate, as well as “radicles,” the hard stem of the bean that gives chocolate its gritty texture. Some chocolate factories incorporate magnets into the sifting process to eliminate the worry of hard metals contaminating the product. However, you cannot completely eliminate the risks associated with hard metal particles and are advised to use a screen that can withstand high temperatures.

Quality standards

In order to make sure consumers are getting high-quality chocolate, manufacturers must follow certain quality standards. The label of a chocolate bar must state how much vegetable fat is added to it. This fat must be compatible with the physical properties of cocoa powder and acquired through a refining or fractionation process. It must not have been modified through enzymatic processes, such as hydrogenation or hydrolysis. This information is vital for the consumer’s safety.

The rules of the food manufacturing process must be followed to prevent contamination of the chocolate product. The Food and Drug Administration (FDA) sets strict standards for how chocolate should be handled. Chocolate manufacturing involves several steps, each introducing increased risk of contamination. Consequently, each step should be equipped with adequate safety protocols. Listed below are the standards for chocolate manufactured in factories. Let us consider the details of these standards and how they affect the quality of the chocolate.

Artificial flavorings

Most chocolates are made from natural ingredients, such as cacao beans. But some chocolate makers add artificial flavorings to improve the taste of their products. Cacao beans are dumped on mesh screens, where they are heated to loosen their shells. A machine called a winnower then removes the shells. Then, the chocolate beans are melted and flavored. In some cases, artificial flavorings are not used at all.

To determine whether a chocolate product contains artificial flavorings, one must know its ingredients. There are two kinds of artificial flavorings: natural and synthetic. While natural flavors are cheaper to make, the process of extracting them is more environmentally harmful. Also, artificial flavorings are cheaper and more environmentally friendly than their natural counterparts. If you’re concerned about artificial flavorings, check the label carefully.

Temperature at which chocolate is made

The production of chocolate is complicated by two factors: temperature and humidity. The ideal storage temperature for chocolate is between 15 and 17 degrees Celsius with humidity levels less than 50%. These conditions increase the shelf life and prevent fat blooming. The shelf life of milk chocolate is about two months while that of dark chocolate can reach two years. Chocolate production begins with the cocoa beans that are then packaged in jute bags and transported via sea. The ideal temperature for transporting cocoa beans is between 70 and 75 percent relative humidity, while their moisture content is six to nine percent.

The temperature at which chocolate is made in factories varies according to the type of chocolate. Dark chocolate is made at temperatures of 176 degrees Fahrenheit, while milk chocolate is made at 131 degrees Fahrenheit. It must be temper-treated to obtain a tight, shiny structure. The chocolate must also be free of fingerprints. The tempering process is a highly controlled process. As part of the tempering process, the cocoa butter is cooled and solidified.

Ingredients used to make chocolate

There are several ingredients that go into making a good piece of chocolate. Typically, the final product is at least 50% sugar. Added sugar is usually sucrose, but can also be lactose in milk chocolate. Other sugars used in chocolate making recently include fructose, sorbitol, and polydextrose. Chocolates must be tempered properly to prevent brittleness. High humidity is one of the main causes of sugar bloom. It occurs when moisture condenses on the surface of the chocolate. The sugar in the chocolate extracts out and recrystallizes on the surface.

Industrial chocolate manufacturers use a cocoa liquor and sugar as the main ingredients. Depending on the brand, some manufacturers substitute soy lecithin for cocoa butter. The soy lecithin is GMO-free. Other chocolate manufacturers use a synthetic emulsifier called PGPR derived from castor oil. Both sugar and cocoa butter are present in milk chocolate. Adding soy lecithin to milk chocolate can result in a smoother texture.
