Brief Introduction

monosodium glutamate refining activated carbon is tailor-made for MSG production industry, adopting premium coconut shell as raw material and processed via precise carbonization and activation. It owns matched mesopore structure targeted at pigment molecules, delivering stable and lasting decolorization effect for MSG mother liquor continuous refining. Low iron impurity avoids influencing finished product brightness, which perfectly fits food-grade decolorization demands.

Iodine value	1100-1300 mg/g
Methylene blue decolorization value	11-15 ml
Iron content	≤0.1 ppm
Granularity	20-50 mesh
Hardness	≥98%
Ash content:	≤3%
Moisture	≤5%
pH	4-7.5

Core Advantages

Special mesopore layout greatly enhances adsorption of yellow-brown pigment in MSG mother liquor, realizing efficient continuous decolorization;
Ultra-low iron content ≤0.1 ppm, prevents discoloration of final monosodium glutamate products;
Moderate bulk density ensures smooth flow inside continuous production equipment, less resistance for industrial pipeline operation;
Stable physical indexes, uniform particle size, fewer fine powder to reduce filtration pressure;
Mild pH range 4-7.5, no extra chemical disturbance to MSG liquid system.
