FAQ – Natural Sweetener Solutions

How does GSG perform in acidic conditions?

GSG shows superior stability with only 3-5% degradation at pH 2.5/37°C for 60 days (vs 15-20% for Reb A), making it perfect for carbonated soft drinks and citrus products.

What is the crystallization behavior of GSG?

GSG shows improved crystallization control with 40-50% lower tendency to form crystals than standard steviol glycosides due to glucosyl branches disrupting molecular stacking. Our controlled crystallization achieves 90-120μm particle size with

How does light exposure affect GSG stability?

GSG demonstrates superior photostability with only 2-3% degradation after 1000 lux hours UV exposure (vs 8-10% for Reb A), due to glucose units acting as photoprotectants by absorbing at 280-320nm wavelengths.

Is GSG suitable for diabetic products?

Yes, GSG maintains zero glycemic index (GI=0) and near-zero caloric content (0.2kcal/g) despite glucosylation, with clinical studies showing no impact on blood glucose levels at recommended doses.

How does GSG interact with dairy proteins?

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.

What viscosity impacts does GSG create?

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.

Does GSG show prebiotic effects?

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.

Does GSG cross the blood-brain barrier?

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.

How is GSG metabolized differently?

While conventional steviol glycosides are hydrolyzed by colonic bacteria (7-12h), GSG shows dual-phase metabolism: 40-50% undergoes slow gastric hydrolysis (18-24h) and 50-60% passes through unmodified, as verified by 13C-tracer studies.
