Product Overview:
Isomalto-oligosaccharide (IMO), also known as Isomalto-oligosaccharide, Isomaltooligosaccharide, and Branched Oligosaccharide 1-3:, is classified as Isomalto-oligosaccharide according to China's light industry standards. It is a type of starch sugar, mainly composed of glucose molecules linked by α-1,6 glycosidic bonds in the form of isomaltose, panose, and oligosaccharides with three or more sugar units.
In nature, Isomalto-oligosaccharide rarely exists in a free state but is found as part of branched starch or polysaccharides. It can be found in small amounts in certain fermented foods like soy sauce, yellow wine, or enzymatically produced glucose syrup.
Isomalto-oligosaccharide syrup is a colorless or pale yellow, transparent viscous liquid with a mild sweetness and no off-flavors, free from visible impurities. The sugar powder is an amorphous powder with a mild sweetness, no off-flavors, and free from visible impurities. The final product typically appears as a white powder with a subtle sweetness, similar in texture to white sugar. It can be dissolved in warm water or added to beverages like milk or coffee.
Production Process:
There are two main methods for producing Isomalto-oligosaccharide:
- Using the reverse action of glucoamylase to convert high-concentration glucose solutions into isomaltose, maltose, and other oligosaccharides. However, this method has drawbacks such as low yield, complex products, and a long production cycle, making it difficult for industrial-scale production.
- Using high-concentration glucose syrup derived from starch as a substrate, catalyzed by α-glucosidase to facilitate a glucose transfer reaction. Industrial production of Isomalto-oligosaccharide generally uses starch as the raw material and employs a full enzymatic process, with technology being most advanced in Japan.
Production flow: Starch → Jet Liquefaction → β-Amylase Saccharification → α-Glucosidase Conversion → Decolorization → Ion Exchange → Vacuum Concentration or Spray Drying → Finished Product.
Industrial production of Isomalto-oligosaccharide from starch requires an enzyme known as α-glucosidase, also called glucosyltransferase, or simply α-glucosidase. This enzyme can cleave the α-1,6 glycosidic bonds in maltose and maltodextrin molecules and transfer the free glucose residue to another glucose molecule or to maltose or maltotriose molecules at the α-1,6 position, forming isomaltose, isomaltotriose, isomaltotetraose, isomaltopentaose, and panose.
Benefits and Effects:
Isomalto-oligosaccharide is a type of starch sugar with a certain level of sweetness and relatively stable properties, making it suitable for addition to various foods. Upon ingestion, it can enhance satiety, provide energy, and regulate gut microbiota.
Enhance Satiety: Isomalto-oligosaccharide is made from starch through enzymatic reactions, containing dietary fiber that, when consumed before meals, can enhance satiety and reduce food intake during meals.
Provide Energy: Isomalto-oligosaccharide contains various types of sugars, providing some calories, but it doesn't easily raise blood sugar levels. Moderate intake can provide the body with a certain amount of energy.
Regulate Gut Microbiota: Isomalto-oligosaccharide is not hydrolyzed or digested in the gastrointestinal tract. It can reach the large intestine directly, where beneficial bacteria utilize it, promoting their growth while inhibiting harmful bacteria and the production of toxins and putrefactive substances, helping to maintain the balance of intestinal microflora.
Promote Digestion: Isomalto-oligosaccharide contains dietary fiber that can stimulate gastrointestinal motility and help maintain gut microbiota balance, thus aiding in food digestion and absorption, and preventing or alleviating constipation.
Prevent Tooth Decay: Isomalto-oligosaccharide is not broken down by enzymes in the mouth and is not utilized by cariogenic streptococci. When combined with sucrose, it inhibits the synthesis of insoluble glucan, making it difficult for dental plaque to adhere to teeth, and it can help prevent the formation of dental calculus, thereby helping to prevent tooth decay.
Food Applications: Health Foods, Food, Medicine, Beauty
Due to its excellent quality and safety, Isomalto-oligosaccharide, as a superior prebiotic, has been widely used in industries such as livestock, healthcare, daily care, and food additives.
Infant Products:
Isomalto-oligosaccharide is widely used in infant products for the production of prebiotic glucose, infant formula, rice powder, and other products.
High-Purity Health Supplements:
As a functional health supplement, prebiotics are not widely used in the health supplement industry, and high-purity products are mainly offered by the Lijian brand. With functional components reaching 90%, they fully showcase the advantages of prebiotics and maximize their functionality. Since these are non-pharmaceutical applications, the user base is very broad, especially suitable for people with intestinal problems.
Daily Flavor Additives:
Sweeteners.
