Overview
Laevulose, commonly known as fructose, is a naturally occurring monosaccharide found in fruits, honey, and root vegetables. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion. Fructose is widely used in the food industry due to its sweetening properties, which are approximately 1.2 to 1.8 times sweeter than sucrose. In addition to its role as a sweetener, fructose is used in medical applications, particularly in intravenous nutrition for patients who cannot metabolize glucose. Its rapid absorption and metabolism make it a preferred choice in certain therapeutic contexts. The compound is also a key ingredient in sports nutrition products, providing quick energy to athletes.
Physical and Chemical Properties
Laevulose is a white crystalline powder with a sweet taste and hygroscopic properties, meaning it readily absorbs moisture from the environment. Its molecular formula is C6H12O6, and it has a molecular weight of 180.16 g/mol. The compound melts at 103°C (217°F) and is highly soluble in water, making it easy to incorporate into liquid formulations. As a reducing sugar, fructose can participate in the Maillard reaction, which is responsible for browning in cooked foods. This property is leveraged in baking and food processing to enhance flavor and appearance. The density of fructose is 1.69 g/cm³, and it is stable under normal storage conditions, though it should be kept away from moisture to prevent clumping.
Main Applications
The primary use of laevulose is as a sweetener in the food and beverage industry. It is found in soft drinks, baked goods, candies, and dairy products. Due to its high sweetness level, it is often used in reduced-calorie products to achieve the desired sweetness with less quantity. In the medical field, fructose is used in parenteral nutrition solutions for patients with glucose intolerance or diabetes. It is also utilized in sports drinks and energy gels to provide quick energy for athletes. Additionally, fructose serves as a precursor in the production of high-fructose corn syrup (HFCS), a widely used sweetener in processed foods.
Safety and Storage
Laevulose is generally recognized as safe (GRAS) by regulatory agencies when consumed in moderate amounts. However, excessive intake can lead to metabolic disorders such as insulin resistance and fatty liver disease. It is advisable to monitor fructose consumption, especially in individuals with preexisting health conditions. For storage, fructose should be kept in a cool, dry place away from moisture to prevent clumping and degradation. Properly sealed containers are recommended to maintain product quality. Industrial users should ensure that storage areas are well-ventilated and free from contaminants to avoid compromising the purity of the compound.
B2B Procurement Guide
When procuring laevulose, it is essential to verify the supplier's compliance with food-grade standards, such as those set by the FDA or equivalent regulatory bodies. Key factors to consider include purity levels, moisture content, and the absence of contaminants. Certificates of analysis (CoA) should be requested to confirm these parameters. Price ranges for fructose typically vary between $1.50 to $3.00 per kg, depending on quantity and supplier. Bulk purchases may offer cost savings, but buyers should also consider logistics and storage capabilities. Establishing long-term relationships with reputable suppliers can ensure consistent quality and reliable delivery schedules.
