What is Silicon Dioxide E551

Additive E551, also known as silicon dioxide, is a substance commonly used as a food additive. It comes in powder or gel form and is used as an anti-caking agent, thickener, absorbent and stabilizer. Silicon dioxide is produced from silica, a natural compound found in sand and rock. It is a safe and non-toxic additive, so it is considered suitable for use in foods and supplements. The main function of E551 is to prevent ingredients from agglomerating during food manufacturing, processing or storage. It helps keep foods in powder or granule form and prevents lumps from forming. In addition to its anticoagulant function, silicon dioxide can also act as a moisture absorber, preventing foods from becoming wet or sticky. It can also function as a stabilizer by improving the texture and consistency of food products. Importantly, the E551 additive is used in a wide variety of processed foods, such as baked goods, baking mixes, condiments, sauces, desserts, dairy products, meat products, and many others. However, its use is subject to regulations and limits established by food safety authorities. In summary, E551 additive or silicon dioxide is a food additive used to prevent caking, absorb moisture, and stabilize foods. It meets safety standards and is present in many processed food products.

How do you get Silicon Dioxide or E551?

The additive E551, also known as silicon dioxide, is obtained through chemical processes from silicon, which is an abundant chemical element in the Earth’s crust. Below are the main steps to obtain the E551 additive

Silicon extraction Silicon is extracted from materials such as sand or quartz, which are rich in this element. There are different methods to extract silicon, but in general, they involve using purification and separation techniques to obtain pure silicon.

Oxidation of silicon The silicon obtained undergoes an oxidation process by which it is converted into silicon dioxide. In this process, silicon combines with oxygen present in the air to form silicon dioxide.

Purification and refining The resulting silicon dioxide is subjected to purification and refining processes to eliminate impurities and obtain a product of high quality and purity. These processes may include techniques such as filtration, evaporation or crystallization.

Form and presentation of the additive Depending on the specific use of the E551 additive, silicon dioxide can be presented in different forms, such as powder, gel or granules. The final form of the additive will determine its application and how it will be used in different industries. It is important to keep in mind that obtaining the E551 additive is a process carried out by specialized industries and specific scientific technical knowledge is needed to carry it out. As consumers, it is not possible to obtain this additive directly at home.

Food use of Silicon Dioxide E551

The additive E551, known as silicon dioxide, is commonly used in the food industry as an anti-caking agent, thickener and moisture absorber. Below are some of the most common food uses of this additive

Chocolates and confectionery products Silicon dioxide is used in the production of chocolates and confectionery products to prevent them from sticking each other, which helps maintain their shape and appearance.

Spices and Seasoning Blends Many powdered spices and seasoning blends contain silicon dioxide to prevent clumping and maintain fluidity.

Powdered soups and sauces The E551 additive is used in dehydrated powdered soups and sauces to prevent them from caking and facilitate their rapid dissolution when added to hot water.

Baked Goods Silicon dioxide is used in baked goods such as breads, cookies and cakes to improve their texture, preventing lumps from forming and maintaining their sponginess.

Food supplements In the production of different food supplements, E551 is used as an anti-caking agent to prevent the formation of lumps and improve mixing. It is important to note that, although the E551 additive is safe for human consumption in the permitted quantities, it is recommended to follow a balanced and varied diet that includes natural and fresh foods whenever possible. Additionally, if you have any food allergies or intolerance, it is essential to read product labels and consult a health professional before consuming foods that contain additives.

Industrial use of Silicon Dioxide E551

The additive E551, also known as silicon dioxide, has several industrial uses. Some of them are detailed below

Pharmaceuticals Silicon dioxide is used in the production of medicines and dietary supplements as an anti-caking agent. It helps prevent ingredients from agglomerating and ensures correct dosage of pharmaceutical products.

Food E551 is used in the food industry as an anti-caking agent in powders and granules, such as salt, sugar, spices, soup powders, among others. It helps prevent ingredients from sticking to each other and allows for better dispersion and fluidity.

Beverages In beverages, the additive E551 is used as a fining agent. It helps eliminate suspended impurities and improve the visual appearance of beverages, especially wines, juices and beer.

Cosmetics In the cosmetics industry, silicon dioxide is used as a moisture-absorbing agent. It is present in products such as face powder, powder makeup, hair care products and deodorants to absorb excess moisture and control shine.

Chemical industry E551 is used as a filler or filler in some chemical products, such as sealants and rubbers, to improve their mechanical properties and the workability of the materials. It is important to note that, although silicon dioxide has been evaluated and approved as safe for use in foods and products, it is always advisable to read labels and follow manufacturers’ recommendations for use.

Recommended consumption of Silicon Dioxide E551

The European Food Safety Authority (EFSA) has set an acceptable daily intake (ADI) for the additive E551, also known as silicon dioxide, at 40 mg/kg body weight. This means that it is safe to consume up to this daily amount of the additive. However, it is important to note that silicon dioxide is used in a wide variety of food products, such as chocolates, baked goods, condiments, and dietary supplements, so it is possible for it to accumulate if multiple foods with this additive are consumed. throughout the day. Therefore, it is recommended to follow a balanced and varied diet, and to read product labels to determine if they contain the additive E55

Improves texture Silicon dioxide is used as an anti-caking agent in many powdered foods, such as spices, to prevent that lumps form. It helps improve the texture and fluidity of these products, facilitating their handling and dispersion.

Stabilizes emulsions This additive is used as an emulsifier in food products such as salad dressings and sauces. It helps maintain the stability of the emulsion, avoiding unwanted separations between the ingredients.

Absorbs moisture Silicon dioxide has hygroscopic properties, which means it can absorb moisture from the environment. For this reason, it is used in food products that need to keep their moisture content controlled, such as certain sweets or dried foods.

Protects against moisture In addition to absorbing moisture, E551 also acts as a protective barrier against it. It is used as a coating on foods such as dried fruits, preventing environmental humidity from affecting and deteriorating them.

Increases shelf life Silicon dioxide is used as a preservative in dehydrated foods, such as instant soups or canned foods.
