2026-05-10

1. Sensory Characteristics

White powder; odorless, free of impurities, and free of lumps.

2. Key Physicochemical Parameters

Purity: ≥99.5%

Moisture Content: ≤8.0%

Degree of Substitution: 0.20–1.50 (0.65–1.40 is commonly used in food applications)

pH Value: 6.0–8.5

Chloride Content: ≤1.2%

Sodium Glycolate: ≤0.4%

Viscosity: Classified into Low, Medium, or High viscosity grades depending on the specific model; select the appropriate grade based on requirements.

3. Heavy Metal Safety Limits

Lead (Pb) ≤2.0 mg/kg; Arsenic (As) ≤3.0 mg/kg; Mercury (Hg) ≤1.0 mg/kg; Cadmium (Cd) ≤1.0 mg/kg.

4. Implementation Standard & Usage

Implementation Standard: GB 1886.232-2016

Used in food products as a thickening, stabilizing, and emulsifying agent; added in appropriate quantities based on production requirements.
