The World Health Organization (WHO), in their recent ground-breaking guidelines, advised against the use of non-sugar sweeteners (NSS) for weight control and reducing the risk of noncommunicable diseases (NCDs). A systematic review found no long-term benefits in reducing body fat with NSS and indicated potential risks such as type 2 diabetes and cardiovascular diseases. It is essential to emphasize that IMOs (Isomalto-Oligosaccharides), in contrast, are a naturally occurring type of sweetener with minimal sugar content. They have a longstanding history of being utilized as prebiotic fiber sweeteners in Asian cuisine for over three decades. IMOs, with approximately 50% of the sweetness of sugars, are regarded as a low-calorie carbohydrate source. Multiple well-controlled randomized trials have consistently shown that IMO is safe and well-tolerated by individuals.
In the dynamic realm of functional foods and beverages, where innovation knows no bounds, IMOs stand out as one of the most buzz-worthy ingredients. IMOs’ unique properties and versatility makes them a powerhouse ingredient in the world of food and beverage formulation. In this article, we will explore the exciting world of IMOs and how they can enhance the texture, taste and overall quality of food and beverages. Get ready to unwrap the secrets of this incredible ingredient!
What are IMOs?
Oligosaccharides are carbohydrate chains typically containing 3 to 10 sugar (monosaccharide) units joined together by glycosidic bonds, sometimes including disaccharides and smaller chains than polysaccharides. Oligosaccharides can be found naturally in various foods. IMOs, which occur naturally in various fermented foods such as miso, sake, soy sauce, and sourdough, as well as honey, are glucosyl saccharides that contain one or more α -1,6-glycosidic linkages sometimes accompanied by α-1,4, α-1,3 and/or α-1,2 linked glycosidic bonds. The production of commercial IMOs is primarily derived from a diverse range of starch sources. These commercially available IMOs are a mixture of oligosaccharides with the main degrees of polymerization (DPs) ranging from 2 to 102.
How to Make Soluble IMOs from Insoluble Starch?
Commercial IMOs are produced through advanced enzymatic processes. The starting material used is starch, a complex arrangement of glucose molecules linked together primarily through alpha-1,4 glycosidic linkages which are easily broken down by digestive enzymes in the body. As shown in Figure 1, the starch polysaccharides can be enzymatically broken down by α-amylase(s) into smaller glucose chains, such as dextrins, maltodextrins, and smaller malto-oligosaccharides. Next, with the aid of a cutting-edge enzyme called α-transglucosidase, the glucose units are reassembled with slowly digestible alpha-1,6 glycosidic bonds. Downstream purification steps ensure the production of high-quality IMOs. The end-product can be obtained in either syrupy or powder forms, ready for use in various applications. This innovative enzymatic process allows for the conversion of insoluble starch into soluble IMOs, providing a versatile ingredient for multiple industries.
What is VitaFiber® IMO?
As the exclusive producer of VitaFiber® IMO in North America, BioNuetra North America Inc. proudly manufactures this exceptional product using its patented process. With a focus on utilizing high purity starch (98 to 99% on a dry basis), the primary sources of starch for VitaFiber® IMO are tapioca, pea and corn for their quality and popularity. Employing BioNeutra’s patented manufacturing process, VitaFiber® IMO is produced as a remarkably pure IMO substance, with less than 3% of glucose and over 90% IMOs (on a dry basis), regardless of the starch source used.
