Product Introduction
Polyfructose, also known as oligofructose, is a type of fructan, which is a polymer of fructose molecules. It is often used as a food additive, valued for its prebiotic effects and its ability to improve the texture and taste of food products. Polyfructose is typically derived from inulin, a naturally occurring polysaccharide found in plants like chicory root.
Production Process
The production of polyfructose generally involves extracting inulin from chicory roots, followed by enzymatic hydrolysis. The inulin is cleaved using enzymes, such as inulinase, to produce shorter chains of fructose molecules. These shorter chains are then purified, concentrated, and dried to obtain the final polyfructose product. The specific conditions of the enzymatic hydrolysis, such as enzyme concentration, temperature, and reaction time, can be controlled to influence the average chain length and properties of the resulting polyfructose.
Functions and Effects
Polyfructose acts as a prebiotic, meaning it promotes the growth of beneficial bacteria in the gut. These bacteria, such as Bifidobacteria and Lactobacilli, ferment polyfructose in the colon, producing short-chain fatty acids (SCFAs) like acetate, propionate, and butyrate. SCFAs provide energy for colon cells, enhance gut barrier function, and exert systemic effects on metabolism and immunity [1]. By selectively stimulating the growth of beneficial bacteria, polyfructose helps improve gut health, enhance nutrient absorption, and regulate bowel movements.
Application Scenarios
Polyfructose is widely used in the food and beverage industry. It can be added to yogurt, dairy products, cereals, baked goods, and beverages to improve their nutritional profile and texture. In dairy products, it can enhance creaminess and mouthfeel. In baked goods, it can improve moisture retention and reduce sugar content. Polyfructose is also used in dietary supplements and functional foods to promote digestive health and overall well-being. Its mild sweetness makes it a suitable sugar substitute in various applications.
Packaging and Storage
Polyfructose should be packaged in airtight containers to prevent moisture absorption and maintain its quality. It should be stored in a cool, dry, and ventilated place, away from direct sunlight and heat sources. Under these conditions, polyfructose typically has a shelf life of 24 months. Proper storage is essential to prevent clumping, discoloration, and degradation of the product.
