SusCarb™ Dextrin - Premium Energy Source

SusCarb™ Dextrin - Sustainable Carbohydrate

SusCarb™ is a unique highly branched cyclic dextrin (HBCD) from Zymebase Inc., utilizing cutting-edge green biotechnology. HBCD is a new type of maltodextrin produced from waxy corn starch using the cyclization reaction of a branching enzyme [1]. SusCarb™ has a higher branching ratio and a narrower and more uniform molecular weight distribution than other HBCD’s on the market [2] , but maintains the physio-biochemical attributes of HBCD including high molecular weight, low osmolarity, and high solubility.

Suscarb is ideal for sports and fitness enthusiasts who want to enhance their endurance, exercise performance by supplying energy for a longer period. It can be used as a pre, intra, and post-workout supplement.

Apparent Characteristics

Highly soluble in water
SusCarb™ Dextrin
  • Highly soluble in water
  • Transparent
  • Colorless
  • Odorless

Moisture Absorption and Stability

·Moisture Absorption and Stability
  • Low moisture absorption (<18% at 40°C, 75% humidity)
  • Highly stable

Molecular Weight Distribution and Purity

Molecular Weight Distribution and Purity

Compared to HBCD products on the market, SusCarb™ has:

  • Narrower and more uniform molecular weight distribution
  • Almost no oligosaccharides
  • The average molecular weight is around 60, 000 ‒ 70, 000 Da

Branching Ratio

glycosidic bonds

SusCarb™ has more α-1, 6-glycosidic bonds:

  • 11% higher than other commercially available HBCD products
  • 40% higher than maltodextrin

The higher branching percentage of α-1, 6-glycosidic bonds correlates with a slower release of glucose in vivo.

Lower Osmolarity

The significantly lower osmolarity of HBCD makes it an ideal sports drink ingredient. Compared to other carbohydrates, HBCD can not only easily replenish energy, but also effectively manipulate and deliver essential electrolytes and other solutes.
Lower Osmolarity
Osmotic pressures of different carbon sources [4]

Prompt Gastric Emptying Time

A lower change in flatulence score was observed in the HBCD group , mainly attributed to faster gastric emptying and absorption.
