It covers the properties, applications, safety considerations, identification methods, storage, and handling of sucrose benzoate, offering valuable insights for professionals in the food industry and researchers.
Introduction to Sucrose Benzoate
Sucrose benzoate, also known as E211, is a food additive commonly used as a preservative and flavor enhancer. It is a salt of benzoic acid and sucrose, which is a disaccharide composed of glucose and fructose. This compound is widely used in the food industry due to its effectiveness in preventing the growth of bacteria, yeast, and molds, thereby extending the shelf life of various products.
Properties of Sucrose Benzoate
Sucrose benzoate is a white, crystalline powder that is odorless and slightly sweet-tasting. It is highly soluble in water and has a melting point of approximately 180°C. The compound is stable under normal storage conditions and does not degrade easily, making it a reliable preservative.
Applications of Sucrose Benzoate
Sucrose benzoate is used in a wide range of food products, including baked goods, confectionery, dairy products, and beverages. It is particularly effective in preventing the growth of molds and yeasts in these products, which can lead to spoilage. Additionally, it is used as a flavor enhancer in certain applications, such as in the production of chewing gum and hard candies.
Safety Considerations for Sucrose Benzoate
Sucrose benzoate is considered safe for consumption by the general population when used within the recommended limits. The acceptable daily intake (ADI) for sucrose benzoate is set at 5 mg/kg body weight by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). However, individuals with allergies to benzoates or other food additives should exercise caution when consuming products containing this compound.
Identifying Sucrose Benzoate
Identifying sucrose benzoate can be done through various methods, including chemical tests and instrumental analysis. One common chemical test involves adding a few drops of ferric chloride solution to a sample of the compound. If a purple color develops, it indicates the presence of benzoic acid, a key component of sucrose benzoate. Additionally, instrumental methods such as nuclear magnetic resonance (NMR) and mass spectrometry can be used for more precise identification.
Storage and Handling of Sucrose Benzoate
Proper storage and handling of sucrose benzoate are crucial to maintain its effectiveness and safety. The compound should be stored in a cool, dry place, away from direct sunlight and heat. It is also important to keep it in a tightly sealed container to prevent moisture absorption and contamination. When handling sucrose benzoate, it is advisable to wear gloves and a mask to avoid skin and respiratory irritation.
Conclusion
The Ultimate Guide to Identifying and Using Sucrose Benzoate CAS 12738-64-6 serves as a valuable resource for professionals in the food industry and researchers. By providing detailed information on the properties, applications, safety considerations, identification methods, storage, and handling of sucrose benzoate, this guide equips readers with the knowledge necessary to make informed decisions regarding the use of this food additive.
