Product Overview
Amino acids are the building blocks of proteins and, in free form, the most readily absorbed nitrogen source a plant or an animal can take up. JINGFENG’s amino acid range is produced from plant protein (soybean) or animal protein by acid or enzymatic hydrolysis, which breaks the protein chain down into free amino acids, short peptides and water-soluble nitrogen. The result is a 100% water-soluble input used as a foliar and fertigation biostimulant, a chelating agent for trace elements, and a feed-grade protein source.
80% Acid Hydrolyzed Amino Acid Powder Ⅱ is the high-purity compatibility grade of our plant-source amino acid range. The protein is broken down by acid hydrolysis and then purified, which delivers a guaranteed ≥ 80% total amino acids with ≥ 75% in the free form — the fraction that plants and animals absorb directly, without a further breakdown step. It is the grade to specify when the powder has to survive demanding liquid formulations.
It is supplied as a fine, free-flowing white powder that is 100% water soluble and carries a ≤ 3% chloride ceiling, so it is safe for chloride-sensitive crops and for feed rations where salt load matters. In concentrated liquid fertiliser systems the white grade holds its solubility where ordinary hydrolysates can drop out, and the clean white appearance is also preferred for premium water-soluble blends and visual quality checks.
Because the free amino acid share is high, the response is fast: the material is taken up through the leaf or the gut as single amino acid molecules rather than as protein that has to be digested first.
Key Benefits
≥ 80.0% total amino acids
A guaranteed floor of ≥ 80.0%, with ≥ 75.0% in the free form that plants and animals absorb directly.
Dissolves completely
100% water soluble with no residue, so it can go straight into the spray tank or through a drip line.
High free amino acid share
A large part of the load is in the free form, which plants and animals absorb without further breakdown.
Low chloride option
Low-chloride grades avoid salt burn on chloride-sensitive crops and keep the salt load down in feed rations.
Blend-friendly
A free-flowing powder that disperses evenly into NPK, organic fertilizer and feed premixes, even at low inclusion rates.
COA on every batch
Each lot ships with a Certificate of Analysis stating the tested total amino acids, free amino acids, total nitrogen, chloride and heavy metals against the stated Chinese industry standards.

Form & Solubility
Form: fine, free-flowing powder with low dust, easy to weigh out by the bag and to blend into dry mixes.
In water: 100% water soluble. It wets out quickly and dissolves cleanly under light agitation, leaving no residue to block filters, spray nozzles or drip lines.
Handling: use standard dust protection when handling bulk. Reseal opened bags to keep moisture out.
Why a compatibility grade. A water-soluble fertiliser formulation is a crowded solution: NPK salts, trace elements, and a pH that is often pushed upwards to keep everything in solution. Protein hydrolysates are sensitive to that environment — in a concentrated, high-pH NPK + trace-element system a standard hydrolysate can lose solubility and drop out. Grade Ⅱ is the white, compatibility-selected grade: it keeps a uniform solution under those conditions instead of going cloudy or settling out.
How to mix it. Dissolve the powder in water first, then bring in the NPK and trace-element fractions under agitation, and keep the tank moving. Run a 100 mL jar test before the first production batch — it is still the safe habit. For neutral to acidic sprays and dry blends, our original 80% Acid Hydrolyzed Amino Acid Powder Ⅰ does the same job.

How the amino acid grades compare
| Grade | Form | Total amino acid | Free amino acid | Total nitrogen | Best for |
|---|---|---|---|---|---|
| Salt-Free Amino Acid Liquid 30% | Liquid | ≥ 300 g/L | — | ≥ 7.0% | Chloride-sensitive crops; foliar and drip |
| 50% Hydrolyzed Amino Acid Powder | Powder | ≥ 45% | ≥ 40% | ≥ 15% | Cost-efficient foliar and fertigation programmes |
| 60% Hydrolyzed Amino Acid Powder | Powder | ≥ 60% | ≥ 55% | ≥ 12% | General-purpose foliar, drip and flushing |
| 80% Acid Hydrolyzed Amino Acid Powder Ⅱ — Compatibility (this product) | White powder | ≥ 80.0% | ≥ 75.0% | ≥ 12.5% | High-pH liquid NPK and trace-element compounding |
| 80% Acid Hydrolyzed Amino Acid Powder Ⅰ | Powder | ≥ 80.0% | ≥ 75.0% | ≥ 12.5% | Foliar, fertigation, dry blends and feed premixes |
All grades are 100% water soluble and are hydrolysed from plant-source protein. Higher grades carry a larger free amino acid share, so less product is needed per hectare for the same response.

Frequently Asked Questions
What is the difference between Grade Ⅰ and Grade Ⅱ?
Both carry the same guaranteed analysis — ≥ 80% total amino acids, ≥ 75% free, ≥ 12.5% total nitrogen, ≤ 3.00% chloride and 100% water solubility — and both dissolve completely in plain water. The difference is behaviour and appearance once the tank is loaded. Grade Ⅱ is a white powder selected for compatibility: it stays in solution in concentrated, high-pH NPK and trace-element formulations, which is where a standard hydrolysate can go cloudy or settle out. Grade Ⅰ, the original grade, is the cost-efficient choice for foliar, fertigation, dry blending and feed premixes.
Can one product really be used for both feed and fertilizer?
Yes. Its purity, balanced amino acid spectrum, low chloride and heavy-metal control make it suitable for both. In feed it works as a bioavailable protein and amino acid source; in agriculture it supplies nitrogen and free amino acids as a biostimulant.
What is the difference between total and free amino acids?
Total amino acids include both the free molecules and the amino acids still bound in short peptides, measured after full hydrolysis. Free amino acids are the single, unbound molecules that a plant leaf or an animal gut can take up immediately. This grade guarantees ≥ 80% total and ≥ 75% free, so most of the load needs no further breakdown.
Is it plant source or animal source?
This grade is plant source, hydrolysed from soybean protein. We also produce animal-source grades; tell us which your market or certification body requires and we will quote the matching product.
How do I dilute it?
For foliar spraying dilute 1:2000 to 1:2500 with clean water; for drip or fertigation 1:1500 to 1:2000; for seed soaking 1:2000 to 1:3000; for root drenching 1:1000 to 1:1500. Always add the product to the water, not water to the product, and run a jar test before tank-mixing with agrochemicals.
What is the chloride content and why does it matter?
The guaranteed ceiling is ≤ 3.00%. A low chloride load avoids salt burn on chloride-sensitive crops such as strawberries and tobacco, and keeps the salt burden down in monogastric feed rations.
Is it suitable for organic farming?
Hydrolysed plant-source amino acids are widely accepted in organic production. Rules differ by market and certifier, so please check with your certification body and ask us for the input list and technical data sheet you need.
How is it packed and what is the minimum order?
Standard pack is a 20 kg or 25 kg bag with inner liner, with 1 kg and 10 kg options for sampling. MOQ one pallet; 7–15 days ex-works. Private-label printing and custom blends are available on request.
