Cluster Dextrin (Highly Branched Cyclic Dextrin)

Cluster Dextrin (Highly Branched Cyclic Dextrin) is a carbohydrate-dominant ingredient derived from waxy corn starch via branching enzyme treatment. Macronutrient composition per 100g: Carbohydrates approximately 95-98g (primarily as complex cyclic dextrin chains), Protein less than 0.5g, Fat less than 0.5g, Dietary Fiber approximately 0-1g. Caloric density approximately 380-400 kcal per 100g (4 kcal/g as a carbohydrate source). Micronutrient content is minimal given its highly purified processing; trace amounts of sodium (approximately 10-30mg per 100g) may be present depending on manufacturing. Contains no significant vitamins or minerals in meaningful quantities. Bioactive profile centers on its unique cyclic and highly branched molecular structure with a high molecular weight of approximately 160,000 Da and narrow molecular weight distribution (low polydispersity index of approximately 1.06), which distinguishes it from maltodextrin (MW approximately 1,000-10,000 Da). Osmolality is notably low at approximately 40-60 mOsm/kg at a 10% solution concentration, compared to maltodextrin at approximately 500-700 mOsm/kg, facilitating rapid gastric emptying. Glycemic index is estimated to be moderate-to-low relative to simple sugars due to the branched structure slowing enzymatic digestion. Bioavailability is high with preferential absorption in the small intestine; gastric emptying rate is significantly faster than glucose or maltodextrin solutions, contributing to sustained plasma glucose elevation without sharp insulin spikes.
