Amino Acid 80 Explained: Composition and Formulation Use

What the Number Describes

The 80 refers to total amino acids in the specification. It does not mean that every batch contains 80% free amino acids, and it does not guarantee a stronger crop response than every lower-concentration product on the market.

The table below gives the current published specification together with an independent result. The 75.37% free-amino-acid value was reported by Eurofins (Chengdu), a CNAS-accredited laboratory, using method GB/T 18246-2019 under certificate AR-26-Y3-008791-02 issued on 29 April 2026, and it describes the tested sample. Use the current specification for contractual requirements and the assigned batch COA for shipment release.

Why Total and Free Values Differ

A protein hydrolysate contains free amino acids, small peptides and other soluble protein-derived components. A total-amino-acid test generally releases amino acids from peptide-bound forms during the laboratory analysis itself, while a free-amino-acid test measures only what is already unbound under the stated method.

Method name, sample preparation, moisture basis and calculation basis all move the result. Ask both the supplier and the laboratory to identify each of them before treating two numbers as equivalent.

Where a High-Concentration Grade Fits

Concentration buys formulation space and reduces the mass moved per unit of amino acid delivered. That matters most in concentrates and in export products where freight is a visible line in the cost model.

• Concentrated water-soluble fertilizer formulations
• Foliar or fertigation products requiring a high amino acid contribution
• Liquid concentrates, after stability testing
• Low-inclusion-rate formulations
• Export products where freight per kilogram of total amino acids matters

The Freight Calculation and Its Limits

On a theoretical total-amino-acid basis, one kilogram of an 80% product carries the same quantity of total amino acids as roughly 1.78 kilograms of a 45% product. In a container of 4,000 tons-per-month scale production shipped FOB Shanghai or Qingdao, that ratio is a real cost argument.

The calculation does not prove equivalent field performance. The free-amino-acid fraction, peptide profile, salts, pH and the final application rate all have to be considered alongside it.

The same ratio works against the grade in a low-value blend. If the finished product only needs a modest amino acid declaration and the bag has space for filler anyway, paying a concentration premium buys nothing but a smaller inclusion rate and a tighter dosing tolerance on the blending line. Concentration earns its price where freight, drum size or formulation space is the binding constraint, and it should be justified on that basis rather than on the assumption that a bigger number sells better.

Higher Concentration Is Not Automatically Better

A higher grade reduces the amount of powder needed to hit a formulation target, but it can also change solution behaviour, osmotic load, cost and crop-safety margins. Some lower-concentration products carry components that happen to be useful in a particular formulation.

The comparison worth running is not simply 45 against 80. It is the following set of parameters, evaluated on the same basis for each candidate.

• Cost per kilogram of the required component
• Verified total and free amino acids
• Nitrogen and salt contribution
• Solubility at the intended concentration
• Compatibility with the full formula
• Crop performance at the intended dose

Agronomic Claims and Application Testing

Protein hydrolysates may support nutrient-use efficiency and crop responses to abiotic stress, but the published evidence shows substantial variation between products and application conditions, and high free-amino-acid concentrations can be inhibitory in some circumstances. Do not assume that twice the amino acid concentration produces twice the agronomic effect, and do not publish a fixed response time or a guaranteed benefit without trials on the exact product and formulation.

Because the grade is concentrated, application rates copied from a 35% or 45% product may be inappropriate. Start from the current TDS or the locally approved label, then work through a defined sequence before scale-up. Avoid blanket statements about compatibility with NPK fertilizers, calcium, phosphate, copper products or pesticides; compatibility is concentration- and formulation-dependent.

• Confirm water quality and the target solution pH
• Run dissolution and filtration tests
• Conduct jar tests with every planned ingredient
• Test crop safety at several concentrations
• Compare performance against an untreated control under the intended conditions

Organic Status and the Buyer's Document Request

Amino Acid 80 is not automatically eligible for organic farming because it is a protein hydrolysate. Acceptance depends on the exact source, process, formulation, intended use and certification program, and buyers have to verify current documentation for the exact product and destination market.

Before approving the grade, request the full package so that every marketing statement can be traced back to a document. Everwell Bio issues a batch-specific COA with each shipment and supplies the TDS and SDS on request, with regular orders running on a 30-day lead time FOB Shanghai or Qingdao.

• Current product specification
• Representative and batch-specific COA
• Total- and free-amino-acid methods
• Total and organic nitrogen values
• Sodium, chloride or other relevant salts
• pH, solubility and insoluble matter
• Raw-material and hydrolysis-process statement
• SDS and storage guidance
• A sample for bench and crop testing
