MTC-30 Gel
A 30 g/serving carbohydrate gel built on a 1:0.8 maltodextrin-to-fructose ratio, delivering multi-transportable carbohydrates with a moderate sodium load optimised for 1–3 hour efforts.
Race-day fuel for events lasting 1–3 hours. Take one gel every 20–30 minutes alongside water.
Per 40 g serving
Primary carbohydrate — glucose-transporter substrate
DE 10-15 gives a neutral flavour profile and manageable viscosity at this concentration.
Secondary carbohydrate — GLUT-5 transporter substrate
Paired with maltodextrin to saturate both SGLT-1 and GLUT-5 pathways.
Electrolyte / alkalising buffer
Contributes ~100 mg sodium; milder on GI than sodium chloride at this dose.
Electrolyte / osmolality tuning
Contributes ~100 mg sodium. Standard food-grade salt.
Electrolyte — potassium replacement
Contributes ~50 mg potassium.
pH adjustment / flavour
Drops pH to ~3.8–4.2; improves palatability and acts as mild preservative.
Thickener / texture agent
0.08 g per 40 g serving (0.2%) gives a viscous gel texture without being sticky.
Preservative
GRAS preservative; active against yeast and mould at ≤0.1% use level.
Flavour
WONF (with other natural flavors) — source-dependent. Placeholder cost used.
Carrier / activity water
Deionised or RO water. Exact amount adjusted to hit 40 g total.
Multi-transportable carbohydrate strategy (maltodextrin + fructose) aligns with the 2023/24 Critical Reviews meta-analysis finding 2:1 or higher ratios maximise oxidation rates.
Sodium load (~200 mg/serving) is consistent with race-day sweat loss replacement recommendations.
Designed to pair with ~200–250 mL water per gel to achieve isotonic conditions in the stomach.
Gel viscosity (via xanthan gum) remains pumpable at temperatures above 10°C.
Hypertonic when consumed without water — always instruct athletes to chase with 150–250 mL water.
Fructose content may cause GI distress in athletes with fructose malabsorption; tolerance should be tested in training.
No tested shelf-life data available; potassium sorbate at 0.1% provides baseline protection but commercial shelf-life requires validation.
Batch production: dissolve sodium citrate and NaCl in water first, blend in maltodextrin and fructose, then add xanthan slurry. Citric acid and potassium sorbate added last. Fill into 40 g foil sachets.
