Frequently Asked Questions
What is the CAS number for Guar Gum?
The CAS (Chemical Abstracts Service) number for Guar Gum is 9000-30-0. This unique identifier is used worldwide for procurement, regulatory compliance, and chemical databases. Guar Gum is also identified by EINECS number 232-536-8 and E number E412 in the European food additive system.
What is the HS code for Guar Gum?
The Harmonized System (HS) code for Guar Gum is 1302.32.30 (mucilages and thickeners derived from locust beans, guar seeds). This code is used for international trade, customs classification, and import/export documentation worldwide.
What mesh sizes is Guar Gum powder available in?
Guar Gum powder is available in 100 mesh (coarse), 200 mesh (standard), 300 mesh (fine), and 400 mesh (superfine). Higher mesh numbers indicate finer particle size and faster hydration. 200 mesh is most common for food applications; 100-200 mesh is used industrially.
What is the viscosity range of Guar Gum?
Guar Gum viscosity ranges from 3,500 to 5,500+ centipoise (cps) measured at 1% concentration using a Brookfield viscometer (RVT, spindle #3, 20 RPM). Higher viscosity grades (5,000+ cps) are preferred for food and pharmaceutical use, while lower viscosity grades suit industrial applications.
What are the chemical specifications of Guar Gum?
Standard chemical specifications: Moisture ≤12%, Protein ≤5%, Ash ≤1.5%, Acid Insoluble Residue (AIR) ≤3%, Fat ≤0.8%, Crude Fiber ≤2%, Gum Content ≥80%, pH 5.5-7.0. These values may vary by grade (food, pharmaceutical, industrial).
What microbiological limits apply to food grade Guar Gum?
Food grade Guar Gum microbiological limits: Total Plate Count (TPC) ≤5,000 CFU/g, Yeast & Mould ≤500 CFU/g, E. coli — Absent in 25g, Salmonella — Absent in 25g, Staphylococcus aureus — Absent in 25g. These comply with JECFA, FCC, and EU specifications.
What packaging options are available for Guar Gum?
Guar Gum is packaged in 25 kg multi-wall paper bags, 50 kg HDPE bags with inner liner, 500 kg / 1 MT jumbo bags (FIBCs), and custom packaging per buyer requirements. All packaging is food-grade certified and designed for moisture protection during shipping.
What international standards does Guar Gum comply with?
B D Guar's Guar Gum complies with JECFA (Joint FAO/WHO Expert Committee), FCC (Food Chemicals Codex), EU Regulation 231/2012 for E412, US FDA 21 CFR 184.1339 (GRAS status), IP (Indian Pharmacopoeia), and BP/EP (British/European Pharmacopoeia) specifications.
