Mint gum is made through a process that combines a specially prepared gum base with sweeteners, flavors, and other ingredients, followed by shaping and packaging. The distinctive mint flavor is added during the mixing stage.
The Gum Making Process
The creation of mint chewing gum involves several key stages, beginning with the preparation of the foundational ingredient: the gum base.
1. Preparing the Gum Base
The making of our gum begins by melting and purifying the gum base. This base is the non-nutritive, chewable core of the gum. Historically, gum bases came from natural sources like tree sap (chicle), but today they are often made from synthetic polymers, waxes, and softeners for consistency and quality.
2. Mixing the Ingredients
Once melted and purified, the gum base is poured into a large industrial mixer. These mixers are capable of handling significant volumes, like holding up to one tonne of ingredients.
- Adding Sweeteners: Sweeteners, such as sugar or sugar substitutes (like xylitol or sorbitol), are added to provide the gum's sweetness.
- Adding Flavors: Flavors, including natural or artificial mint, are crucial for the gum's taste and aroma. Other flavor enhancers might also be included.
- Adding Softeners and Other Additives: Glycerin, softeners, and sometimes coloring agents are added to achieve the desired texture and appearance.
All these ingredients are added at just the right moment and in just the right amounts and then slowly mixed together with the gum base. Precise measurement and timing are essential to ensure the final product has the correct consistency, flavor, and chewability.
3. Cooling and Kneading
After mixing, the warm gum mass is transferred to cooling belts or tables to lower its temperature and allow it to firm up slightly. It is then often kneaded or rolled to achieve a uniform texture and consistency, much like dough.
4. Forming and Cutting
The cooled and kneaded gum mass is then shaped. Depending on the desired final product (sticks, pellets, cubes), the gum is typically rolled into thin sheets or extruded into ropes. These are then cut into individual pieces. For pellet gum, the pieces might be shaped into small pillows or spheres.
5. Coating (for Pellet Gum)
Many pellet gums undergo a coating process. This involves tumbling the gum pieces in rotating pans while applying layers of liquid sweetener and sometimes flavorings. This creates a hard, crunchy outer shell that protects the gum and provides an initial burst of flavor and sweetness. Mint pellet gums often have multiple layers of mint-flavored coating.
6. Packaging
The final pieces of gum, whether sticks or pellets, are then moved to packaging machinery. They are wrapped, bagged, or boxed into their final retail packaging. This protects the gum from moisture and air, maintaining its freshness and quality until it reaches the consumer.
The specific process can vary slightly between manufacturers and types of gum, but these steps outline the general method for making mint chewing gum.
