Protein Hydrolysate 16.9% (Plant Source) (Liquid)
Read the FCO composition, plant source, free amino acid, pH, specific gravity and solubility specifications for Protein Hydrolysate 16.9% Plant Source Liquid.
FCO Composition
| Ingredient | Requirement |
|---|---|
| Protein hydrolysate from Glycine max and Zea mays seeds in 5.5:4.5 ratio through enzymatic (food-grade Alcalase) hydrolysis | Minimum 16.90% by weight |
| Potassium Sorbate and Vegetable-base Fatty Acid | Minimum 21.00% by weight |
| Water | QS |
| Total | 100% |
Finished-Product Specifications
| Parameter | Requirement |
|---|---|
| Free Amino Acids | Minimum 6.3% by weight |
| Specific Gravity | 1.1–1.3 |
| pH (10% aqueous solution) | 4–6 |
| Solubility | Minimum 98.58% |
Why 16.9% Does Not Mean 16.9% Free Amino Acids
The 16.9% number refers to the Protein Hydrolysate component in the formulation. Free amino acids are a different finished-product parameter and are specified separately at minimum 6.3%.
Source / Process
The notified plant source is soybean + maize in a 5.5:4.5 ratio. The notified process uses enzymatic hydrolysis with food-grade Alcalase.
How to Interpret Source, Process and the Finished Specifications
The soybean + maize 5.5:4.5 source ratio and enzymatic hydrolysis with food-grade Alcalase describe the notified formulation context. They should not be read as a shortcut for predicting field performance. Protein hydrolysates are complex mixtures, and scientific reviews show that source material, hydrolysis process, peptide/amino-acid profile, crop and application conditions can all influence biological response.
- 16.9% is the Protein Hydrolysate composition requirement; it is not the free-amino-acid percentage.
- Free amino acids are a separate finished-product specification: minimum 6.3%.
- pH 4–6, specific gravity 1.1–1.3 and minimum 98.58% solubility are conformity parameters for this technical. A value being numerically higher or lower is not automatically “better” unless the applicable specification says so.
- For procurement, compare this technical with the same technical and physical form first; then compare batch COA, source/process consistency, traceability, supply support and commercial terms.
How to Check a Product Using This Technical
- Match the exact technical name and Plant Source wording.
- Check soybean + maize source disclosure where applicable.
- Check the free amino acid, pH, specific gravity and solubility specifications.
- Check batch number, company identity and authorised source.
- Use batch-specific COA/test data when available.
