Dextran is an homo-exo-polymer of glucose (HoPS), naturally produced through fermentation by food-grade Lactic Acid Bacteria. Long-chain, low-branched, high-molecular-weight polymer that dissolve or disperse in water to give improved rheological (gelling, thickening) or physic-chemical (emulsion stabilization, particle suspension, etc.) properties, are important tools for food product formulation. Clean-label product formulation (impact on food choise). Hydrocolloid. Tasteless. Fat replacer (or reductor), gelling agent, stabilizer, emulsifier. It helps to improve product’s texture, rheological, chemical and sensory properties. Optimal water-binding capacity.
– Extremely versatile product (potential addiction in wide variety of foodstuff): it can be used for beverage, topping, dessert, yogurt, ice-cream, sauce, mousse, etc..
– The best option for gluten-free recipes: improve the quality parameters and sensory properties of gluten free products and extend significantly the shelf-life. Dextran addiction is important to achieve an enhanced quality such as better crumb structure and softness and high loaf volume of final product.
Adding BIOerg’s NEXTDEXT®: a promising clean label approach to replace hydrocolloid additives as texturizer both in vegetable containing products or in milk based products.
Dextran is also an ingredient in COSMETIC and PERSONAL CARE (especially skin care) industry, classified as VISCOSITY CONTROLLING BINDING (in cream, lotion, balm formulations, filler, etc.) and moisturizer. Dextran enhances the anti-aging activity of the weak acids and reduces skin irritation; present in natural anti-stretchmark cream formulations.
New fields to explore:
NEXTDEXT® is a strategic natural ingredient, which should be used not only as a thickener (emulsifier, stabilizer, viscosizing agent) but also as gluten-replacer, fat-replacer and as a prebiotic substrate. New applications means new opportunities and business creation by developing standardization of quality and production process and finding out scientific characterization of NEXTDEXT® for food and nutraceutical markets.

Dextran was initially studied in the 1950s as food ingredient, particularly as a thickener. The US Food and Drug Administration currently lists dextran as GRAS (Generally regarded as safe) as ingredient for food and feed applications. In 2001, the European Commission approved the use of dextran in baked goods, up to levels of 5%

Dextran finds a wide range of application in waste water management. Many industries are searching for environmentally acceptable products for treating waste water effluent. Dextran offers many useful features like the stabilisation of alkali and acids at room temperature. It binds metal ions at an alkaline pH and is biodegradable and economical. It is used extensively in waste water treatment during the flocculation process.
