Application and safety assessment of ultrafine, heavy calcium carbonate in the food industry

Ultrafine heavy calcium carbonate is an important inorganic functional material with broad application prospects. In the food industry, ultrafine heavy calcium carbonate is widely used as a thickener, stabilizer, acidity regulator, and leavening agent. Guangxi Longhua New Materials will introduce the application and safety assessment of ultrafine heavy calcium carbonate in the food industry. The application of ultrafine heavy calcium carbonate in the food industry is mainly reflected in the following aspects:

  Ultrafine heavy calcium carbonate is an important inorganic functional material with broad application prospects. In the food industry, ultrafine heavy calcium carbonate is widely used as a thickener, stabilizer, acidity regulator, and leavening agent.

The application of ultrafine heavy calcium carbonate in the food industry is mainly reflected in the following aspects:

 

 Ultrafine Heavy Calcium Carbonate

 

  1. Thickener: Ultrafine heavy calcium carbonate can increase the viscosity and consistency of food, making the food more delicate and the taste better.

  2. Stabilizer: Ultrafine heavy calcium carbonate can prevent the water in food from separating, thereby extending the shelf life of the food.

  3. Acidity regulator: Ultrafine heavy calcium carbonate can neutralize acidic substances in food, thereby adjusting the acidity of the food and making it more palatable.

  4. Leavening agent: Ultrafine heavy calcium carbonate can release carbon dioxide in food, thereby making the food expand and taste better.

  However, the application of ultrafine heavy calcium carbonate in the food industry also presents certain safety issues. On the one hand, the particle size of ultrafine heavy calcium carbonate is very small, and it is easily absorbed by the human body, thus potentially harming the human body. On the other hand, the preparation process of ultrafine heavy calcium carbonate may leave some harmful substances, such as heavy metals, which pose a potential threat to human health.

  Therefore, a safety assessment is needed for the application of ultrafine heavy calcium carbonate in the food industry. The safety assessment mainly includes the following aspects:

  1. Toxicological assessment: Through animal experiments and other methods, assess the potential harm of ultrafine heavy calcium carbonate to human health.

  2. Residue assessment: Assess the potential harm to human health of harmful substances that may remain in the preparation process of ultrafine heavy calcium carbonate.

  3. Safety standard formulation: Formulate safety standards for the use of ultrafine heavy calcium carbonate in the food industry to protect human health.

  In summary, the application of ultrafine heavy calcium carbonate in the food industry has broad prospects, but safety assessments are also needed to protect human health.

Why is edible calcium carbonate added to toothpaste?

One of the core functions of toothpaste is to clean plaque and stains through abrasives, and edible calcium carbonate, due to its unique physical and chemical properties, has become a widely used choice in the industry. This additive not only needs to meet cleaning needs but also needs to comply with food safety standards. The logic behind it involves multiple considerations of material science, production processes, and consumer safety. Safety: From "edible" to "oral friendly" The "food-grade" attribute of edible calcium carbonate is a prerequisite for its use in toothpaste. According to national standards (such as GB 25584-2010), if toothpaste raw materials claim to be "edible", they must pass strict tests for heavy metals, microorganisms, etc., to ensure safety in case of accidental ingestion. Calcium carbonate itself is chemically stable and can be decomposed into carbon dioxide and calcium ions by gastric acid in the gastrointestinal tract, further reducing the risk. In contrast, industrial-grade calcium carbonate may contain trace amounts of heavy metals or impurities. Although the cleaning effect is similar, there are health risks associated with long-term use. Therefore, the choice of edible calcium carbonate in toothpaste is essentially a double protection against accidental ingestion by consumers. Functionality: Balancing cleaning power and mildness As an abrasive, the hardness and particle size distribution of calcium carbonate directly affect the cleaning effect. Its Mohs hardness is about 3, lower than that of tooth enamel (about 5), which can effectively remove


How to choose the right food-grade calcium carbonate product?

How to choose the right edible calcium carbonate product? In today's era of increasing health awareness, many people are paying attention to calcium supplementation. Whether it is to maintain bone health or to enhance immunity, edible calcium carbonate has become the choice of many people. However, faced with a wide variety of edible calcium carbonate products on the market, how should one choose the right one? Today, let's talk about this topic. Understanding the basics of edible calcium carbonate First, we need to have a basic understanding of edible calcium carbonate. Edible calcium carbonate is a common calcium supplement, which is refined from limestone through chemical reactions. It can not only effectively supplement the calcium elements needed by the human body, but also promote the healthy development of bones. Sounds good, doesn't it? However, choosing the right product is not a simple matter. Product source and production method When choosing edible calcium carbonate, the first thing to consider is the source and production method of the product. Some products may come from unknown sources, or substandard materials may have been used in the production process. Therefore, it is recommended to choose brands that have undergone rigorous testing and have a good reputation. For example, does the product packaging have relevant certification marks, and does it meet national food safety standards? These can help you


Unveiling the Multiple Roles of Calcium Carbonate: From Nature to Food

From nature to food: Unveiling the multiple roles of calcium carbonate Have you ever considered that calcium carbonate is more than just a mineral? In our lives, its roles are astonishingly diverse! From our daily diet to pharmaceutical formulations, it's everywhere. Today, let's talk about this seemingly simple yet extremely important compound - food-grade calcium carbonate. What is calcium carbonate? Calcium carbonate (CaCO3) is a natural mineral commonly found in limestone, marble, and seashells. Its chemical structure allows it to have wide-ranging applications in many fields. You might be thinking, "What does this have to do with my life?" Actually, it has a lot to do with it! For example, food-grade calcium carbonate is one of the important sources of calcium we ingest every day. Sources of food-grade calcium carbonate There are two main sources of food-grade calcium carbonate: natural sources and synthetic sources. Natural calcium carbonate usually comes from minerals, while synthetic calcium carbonate is manufactured in laboratories. Did you know that many calcium supplements and some food additives include food-grade calcium carbonate to increase calcium content and help us maintain better health? Health benefits of food-grade calcium carbonate The biggest selling point of calcium carbonate is its high calcium content; almost every 100 grams provides about 40 grams of elemental calcium. This is suitable for people of all ages.
