Food Grade Pure Glycerol Triacetate¹

Product Description Glycerol triacetate, also known as triacetin, is an organic compound with the chemical formula C9H14O6. It is a clear, colorless, and odorless liquid that is soluble in many organic solvents such as ethanol, ether, and chloroform, and also miscible with water to some extent. Glycerol triacetate is produced by the esterification reaction of glycerol with acetic acid. Industrially, this process typically involves using catalysts like sulfuric acid and carrying out the reaction under controlled temperature and pressure conditions to ensure high yield and purity. In terms of applications, it has a wide range of uses. In the tobacco industry, it serves as a humectant and plasticizer, helping to maintain the moisture content and flexibility of tobacco products. In the food industry, it is utilized as a food additive, functioning as an emulsifier, thickener, and flavor fixative. It is also employed in the cosmetic industry, where it acts as an emollient and solvent in various personal care products. From a safety perspective, glycerol triacetate is generally considered safe for use in the aforementioned applications when used in accordance with established regulations. It has low toxicity and does not pose significant hazards under normal handling conditions. However, as with any chemical, proper handling procedures, including wearing appropriate personal protective equipment and working in well-ventilated areas, should be followed to ensure safety.SpecificationDetailsProduct NameFood Grade Pure Glycerol Triacetate (Triacetin)Chemical Properties- Molecular Formula: CHO- Molecular Weight: 218.20 g/mol- Appearance: Clear, colorless, odorless liquid with a mild, sweet taste.- Solubility: Miscible with water, ethanol, ether, and most organic solvents; insoluble in oils and fats.- Boiling Point: 258°C (at 760 mmHg)- Melting Point: -78°C- Density: 1.156 g/cm3 (at 20°C)Purity & Quality- Purity: ≥99.5% (food-grade standard), with minimal impurities (e.g., free glycerol ≤0.1%, acetic acid ≤0.05%).- Food Safety Compliance: Meets FDA 21 CFR 172.878, EU EFSA, and JECFA standards for food additives, ensuring suitability for direct or indirect food contact.- Microbiological Control: Free from pathogens, with total plate count ≤10 CFU/g, ensuring safety in food applications.Functional Properties- Plasticizing Effect: Acts as a safe plasticizer in food packaging materials (e.g., cellulose films) to improve flexibility and durability without leaching harmful substances.- Solvent Capability: Serves as a solvent for flavors, colors, and preservatives in food and beverage formulations, enhancing solubility and stability.- Moisture Retention: Helps maintain moisture in baked goods, confectionery, and processed foods, extending shelf life.- Non-Toxicity: Classified as GRAS (Generally Recognized as Safe) with no reported adverse effects at typical usage levels.Applications in Food Industry- Confectionery: Used in chewing gum, candies, and chocolates as a plasticizer for gum bases and a softening agent.- Bakery Products: Added to cakes, pastries, and bread to retain moisture and improve texture.- Beverages: Functions as a solvent for natural flavors and colorants in fruit juices, soft drinks, and alcoholic beverages.- Dairy Products: Used in processed cheeses and spreads to enhance smoothness and prevent oil separation.- Food Packaging: Incorporated into edible films and coatings (e.g., for fruits, vegetables) to improve barrier properties and extend freshness.Handling & Storage- Storage Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight and heat sources.
