Messi Biology states that gummies, with their chewy texture and rich flavors, are deeply loved by consumers of all ages. In gummies, the primary function of magnesium carbonate is to act as an anti-caking agent. The manufacturing process of gummies is a drying process involving water evaporation, and the moisture content of the final product is typically very low. In such a low-moisture, high-sugar environment, powdered sugar or raw material particles are extremely prone to absorbing moisture and subsequently clumping together, which leads to poor product flowability and an inability to maintain a loose, granular form.
Magnesium carbonate particles are extremely fine and possess a large specific surface area. They can evenly adhere to the surfaces of sugar particles or ingredients, forming a very thin isolation film. This is akin to putting an “anti-slip suit” on the sugar particles, effectively blocking direct contact between them, thereby preventing caking and ensuring the smooth flow of gummy raw materials during production, processing, and storage.
Magnesium carbonate also acts as a desiccant and carrier. In gummy production, to prevent the products from sticking together, a layer of granulated sugar or powdered sugar is usually dusted on the surface of the molded gummies. However, if this outer layer of sugar absorbs moisture from the air, it can instead become sticky, causing the gummies to adhere to one another or even stick to the packaging bag. Adding an appropriate amount of magnesium carbonate can absorb excess moisture, keeping the outer layer of sugar dry and smooth, and ensuring that every single gummy remains distinct and provides a refreshing mouthfeel.
The addition of magnesium carbonate helps regulate rheological properties. In modern automated production lines, the colloidal base needs to be precisely injected into molds. If the viscosity of the raw materials is unstable or their flowability is poor, it may lead to uneven molding and affect the appearance of the finished product. The lubricating properties of magnesium carbonate can improve the flow performance of the materials, making them easier to handle mechanically and thereby increasing production efficiency.
