Erythritol Cas 149-32-6

Erythritol is a four-carbon sugar alcohol (polyol) and natural sweetener classified chemically as meso-1,2,3,4-butanetetrol (C4H10O4).

Chemical and Physical Specifications

• Chemical Name: meso-1,2,3,4-butanetetrol / meso-erythritol

• CAS Number: 149-32-6

• Molecular Formula: C4H10O4

• Molecular Weight: 122.12 g/mol

• Appearance: White, odorless, crystalline powder, granules, or flakes

• Melting Point: 121 °C – 122 °C

• Boiling Point: 329 °C – 331 °C

• Density / Specific Gravity: ~1.45 g/cm³

• Water Solubility: ~37% to 61% w/w (~370 to 500+ g/L at room temperature, increasing with heat)

• pH Stability: Stable across a broad pH range from pH 2 to pH 10

• Thermal Stability: Heat-stable up to more than 160 °C (resistant to Maillard browning)

• Hygroscopicity: Non-hygroscopic (does not significantly absorb moisture until relative humidity exceeds 80%)

Key Characteristics

• Sweetness: Approximately 60% to 70% the sweetness of sucrose (table sugar)

• Caloric Value: Near-zero calories (roughly 0.2 kcal/g or practically 0 cal/g, as it is mostly not metabolized)

• Glycemic & Insulin Impact: Does not raise blood glucose or insulin levels (glycemic index = 0)

• Dental Health: Non-cariogenic; does not promote tooth decay

• Digestive Tolerance: High digestive tolerance compared to other polyols (such as sorbitol or xylitol) because about 80% to 90% is absorbed in the small intestine and excreted unchanged in the urine.

• Cooling Effect: Exhibits a distinct endothermic heat of solution, producing a mild cooling sensation in the mouth.

• Regulatory Status: Approved as food additive E 968 in the European Union and designated as GRAS

Keep in cool and dry place away of sun, packaging 25 Kg.
