Overview
Rebaudioside is a steviol glycoside extracted from the leaves of the Stevia rebaudiana plant, native to South America. It is one of the sweetest and most stable compounds derived from stevia, making it a popular natural sweetener in the food and beverage industry. Unlike artificial sweeteners, rebaudioside offers a zero-calorie alternative to sugar without compromising on sweetness. Rebaudioside A (Reb A) is the most commonly used form due to its superior taste profile and minimal aftertaste compared to other steviol glycosides. Its natural origin and health benefits have led to widespread adoption in products targeting health-conscious consumers, including diabetic-friendly and low-calorie foods.
Physical and Chemical Properties
Rebaudioside appears as a white crystalline powder with a molecular weight of 967.03 g/mol. It is highly soluble in water and slightly soluble in ethanol, making it versatile for various food and beverage applications. The compound is heat-stable, retaining its sweetness even under high-temperature processing, which is ideal for baked goods and canned products. With a melting point of 196-198°C, rebaudioside remains stable under normal storage conditions. Its high sweetness intensity, approximately 200-300 times that of sucrose, allows for minimal usage in formulations, reducing costs and caloric content. The compound’s stability and solubility profile make it a preferred choice for manufacturers seeking natural sugar alternatives.
Main Applications
Rebaudioside is primarily used as a sugar substitute in the food and beverage industry. It is incorporated into products such as soft drinks, yogurts, candies, and baked goods to provide sweetness without added calories. Its natural origin aligns with consumer demand for clean-label ingredients. Beyond food, rebaudioside is used in dietary supplements and pharmaceutical formulations where sugar reduction is critical. Its ability to maintain sweetness under various processing conditions makes it suitable for a wide range of products. The compound’s versatility and safety profile have also led to its inclusion in tabletop sweeteners and flavored waters.
Safety and Storage
Rebaudioside is generally recognized as safe (GRAS) by the FDA and other regulatory bodies worldwide. However, excessive consumption may cause mild gastrointestinal discomfort in sensitive individuals. It is advisable to adhere to recommended daily intake levels to avoid potential side effects. For storage, rebaudioside should be kept in a cool, dry place away from direct sunlight to maintain its stability and shelf life. Properly sealed containers are recommended to prevent moisture absorption, which could affect the powder’s consistency and performance in formulations.
B2B Procurement Guide
When procuring rebaudioside, businesses should prioritize suppliers who provide certificates of analysis (COA) to verify purity and compliance with food-grade standards. The price typically ranges from $50 to $100 per kg, depending on purity and supplier reputation. Bulk purchasing may offer cost savings, but it’s essential to evaluate storage capabilities to prevent degradation. Partnering with reputable suppliers ensures consistent quality and reliability, which is critical for large-scale production. Additionally, consider suppliers who offer technical support for formulation adjustments to optimize product performance.
