Sodium Gluconate – Food Grade & Industrial Grade
What is Sodium Gluconate Used For?
Sodium gluconate is a versatile multi-industry ingredient with excellent chelating, pH buffering, and water-softening properties. WIS Biotech supplies both food grade sodium gluconate for food processing and industrial grade for construction, water treatment, and metal cleaning.
Key Applications
- Food Industry: Food preservative, pH buffer, and flavor enhancer (E576)
- Construction: Concrete retarder — extends workability of ready-mix concrete
- Metal Treatment: Cleaning and surface treatment agent
- Water Treatment: Scale inhibitor in boilers and cooling towers
- Textile: Dyeing auxiliary agent

Frequently Asked Questions
What is the difference between food grade and industrial grade sodium gluconate?
Food grade meets FCC and E576 purity standards for direct food contact. Industrial grade meets construction and cleaning industry standards with relaxed purity requirements and lower cost.
How does sodium gluconate work as a concrete retarder?
Sodium gluconate delays cement hydration by complexing with calcium ions, extending the workability window of fresh concrete — essential for large pours and hot weather concreting.
Is sodium gluconate environmentally friendly?
Yes. Sodium gluconate is readily biodegradable (>98% in 2 days) and non-toxic, making it an environmentally preferred alternative to phosphate-based chelating agents.
What is the MOQ for industrial grade?
500 kg minimum for industrial grade; 25 kg for food grade samples.
Can you supply in bulk bags (1000 kg)?
Yes. 1000 kg jumbo bags available for industrial grade orders.
