In vivo studies show GSG has ≤0.01% BBB permeability (vs 0.03-0.05% for standard steviol glycosides) due to increased molecular size from glucosylation, confirmed by LC-MS/MS analysis of cerebrospinal fluid in primate models.

GSG creates 35-45% lower osmotic pressure than sucrose at equivalent sweetness, measured at 250-300 mOsm/kg for 10% GSG solutions vs 450-500 mOsm/kg for sucrose, reducing dehydration effects in sports nutrition applications.

GSG's glucosyl groups form molecular capsules that protect volatile flavor compounds (23-35% less evaporation at 60°C vs sucrose), while reducing astringency by 40-60% in tea/coffee applications through polyphenol interaction modulation.

In vitro studies show GSG selectively stimulates Bifidobacterium (2.1× growth) and Lactobacillus (1.8×) without feeding E. coli or C. difficile, with fermentation producing short-chain fatty acids at 60-75% the rate of fructooligosaccharides.

At 10% concentration, GSG solutions show only 1.2-1.5cP viscosity (vs 2-3cP for maltitol or 5-6cP for polydextrose), allowing easy pumping and mixing while providing clean sweetness without textural drawbacks.

The glucosyl groups in GSG reduce hydrophobic interactions with casein by 40-60% (confirmed by SPR analysis), preventing bitterness amplification in dairy, while maintaining 98% stability in UHT milk processing at 140°C for 4s.
