Scope

Main Technical Content: 4.1 Requirements for Polyglutamic Acid Raw Materials Polyglutamic acid raw materials are divided into powder form and liquid form. For powder form, the molecular weight should be 5,000 Da to 3,000,000 Da, and for liquid form, the molecular weight should be 100,000 Da to 3,000,000 Da. Liquid form should also meet the requirements of Table 1. Table 1: Requirements for Polyglutamic Acid Raw Materials (Liquid Form) Item Indicator Appearance Light yellow to brown Polyglutamic acid content (%) 3.5–17.5 pH 5.0–7.5 Water-insoluble matter (%) ≤1.0 4.2 Requirements for Polyglutamic Acid Diammonium Phosphate 4.2.1 Appearance Uniform color, granular form, no mechanical impurities. 4.2.2 Technical Indicators Polyglutamic acid diammonium phosphate should meet the requirements of Tables 2 and 3, and also comply with the declared values. Table 2: Requirements for Granular Polyglutamic Acid Diammonium Phosphate Item Indicator Superior Grade First Grade Pass 18–46–0–15–42–0 14–39–0 Total Nutrients (N + P2O5)/% ≥64.0 57.0 53.0 Polyglutamic Acid (mg/kg) ≥140 Total Nitrogen (N)/% ≥17.0 14.0 13.0 Effective Phosphorus (P2O5)/% ≥45.0 41.0 38.0 Water-Soluble Phosphorus as a Percentage of Effective Phosphorus/% ≥87 80 75 Moisture (H2O)/% ≤2.5 2.5 3.0 Particle Size (1.00 mm–4.00 mm)/% ≥90 80 80 a Moisture is a recommended requirement. The formulations below each grade are typical formulations for that grade. Enterprises can produce products with other formulations, but the total nitrogen and effective phosphorus must have an absolute negative deviation of 1.0% from the declared values, and all items must meet the requirements of the corresponding grade in the table.
