High-Performance Food-Grade Silicon Dioxide by Grace: Purity, Safety, and Versatile Applications in Food Processing, Brewing, and Personal Care

Here is an introduction to Grace's food - grade silicon dioxide: • Basic Information ◦ Company Background: Grace is a world - renowned high - performance specialty chemicals company with more than 4,300 employees, providing services to customers in more than 60 countries and regions around the world. ◦ Product Overview: Grace's food - grade silicon dioxide mainly includes product lines such as SYLOID®, PERKASIL®, SYLODENT®, SYLOBLANC®, and DARACLAR®. • Features ◦ High Purity: The purity of silicon dioxide is usually more than 99%, with extremely low impurity content, meeting strict food - grade standards. For example, the silicon dioxide purity of SYLOBLOC® silicon dioxide anti - caking agent exceeds 99%. ◦ Chemical Inertness: It has chemical inertness, is insoluble in most solvents, and does not react with ingredients in food. It will not affect the color, taste or aroma of food, and can maintain the original quality of food. ◦ Amorphous Structure: The amorphous, non - crystalline structure gives it good stability and safety. It will not crystallize or precipitate during food processing and storage. For instance, DARACLAR® silicon dioxide has amorphous, non - crystalline and high - quality characteristics. ◦ Good Fluidity: It can improve the fluidity of food, prevent adhesion and caking between particles, so that powdery and granular food can maintain a good dispersed state during processing, storage and transportation, facilitating handling and use. ◦ Selective Adsorption: Some products have the property of selective adsorption, which can specifically remove or retain certain components in food. For example, DARACLAR® FA 300 silicon dioxide only adsorbs sensitive proteins in beer, but not the hydrophobic proteins necessary for maintaining foam stability. • Application Fields ◦ Beer Industry: DARACLAR® silicon dioxide is a product specially developed for the brewing process. As a protein adsorbent, it can selectively remove hydrophilic proteins in cold turbidity, extend the shelf life of beer, and does not affect the stability of foam. DARACLAR® FA 300 silicon dioxide can also be used as a filter aid. LUDOX® silica sol is an excellent clarifying agent, suitable for dry beer, cold aging and hot wort. ◦ Food Processing Industry: SYLOID® and PERKASIL® series of silicon dioxide can be used as anti - caking agents and glidants to prevent caking of food raw materials during processing and storage, improve their fluidity, and are widely used in powdery food, nutritional products, seasonings, cereal products, etc. They can also be used as carriers to carry and stabilize active ingredients, vitamins, spices, etc. in food, improving their stability and bioavailability. ◦ Edible Oil Refining Industry: Synthetic amorphous silicon dioxide is used in the refining and processing of edible oils and fats, including post - treatment and enzymatic transesterification. It can help remove impurities, pigments and other unwanted components, improving the quality and stability of edible oils. ◦ Toothpaste and Other Personal Care Industries: SYLODENT® and SYLOBLANC® silicon dioxide are used in toothpaste formulations to provide teeth cleaning and thickening effects. They have excellent whitening performance and fluoride compatibility, and can meet the functional requirements of different toothpaste products such as cleaning, whitening and preventing dental caries. • Safety ◦ Regulatory Certification: Grace's food - grade silicon dioxide products comply with the regulations and standards of many countries and regions, such as the United States Food Chemicals Codex (FCC), European Commission Regulation No. 231/2012 (E551), Japanese food additive specifications and standards, etc. ◦ Authoritative Recognition: The European Food Safety Authority (EFSA) reaffirmed that silicon dioxide (E551) is safe as a food additive under the reported dosage and usage. This conclusion further confirms that Grace's synthetic amorphous silicon dioxide can be safely used as a food additive.
