Food Grade vs Construction Grade Sodium Gluconate Purity Index & Application Guide

Sodium Gluconate is divided into construction grade and food grade according to production standards and impurity control indicators. The two grades have obvious differences in purity, heavy metal content, and safety performance, and must be selected strictly according to actual application scenarios.

Construction grade Sodium Gluconate is mainly used in concrete additives, industrial cleaning, and water treatment. Its purity is above 98%, with conventional control of trace impurities. It focuses on chelating and retarding performance, meeting the large-scale low-cost use needs of the construction and industrial fields.

 

Food grade Sodium Gluconate implements strict food safety production standards, with purity above 99% and ultra-low heavy metal and microbial residue. It is non-toxic and harmless to human body, and is widely used as food additives, nutritional supplements, and beverage stabilizers in the food and beverage industry.

 

In terms of index differences, food grade products have stricter limits on lead, arsenic, and microbial colonies, while construction grade products relax partial safety indicators and focus on industrial use performance. In terms of price, food grade Sodium Gluconate has higher production cost and unit price due to multiple purification processes.

 

In actual selection, construction engineering and industrial cleaning scenarios choose construction grade to control procurement costs; food processing, beverage production, and pharmaceutical auxiliary fields must choose food grade to ensure product safety and compliance. Correct grade selection can avoid quality risks and maximize product use value.
