Direct product answer

What is Food Grade Phosphoric Acid 85%?

Food grade phosphoric acid 85% is a concentrated aqueous solution of orthophosphoric acid used in permitted food processes for acidification, pH control, sequestration and related technical functions.

Commercial suitability depends on the exact formulation or source, current signed specification, intended function, complete food process and destination-market rules. A webpage is qualification guidance; the agreed specification and batch COA govern supply.

Buyer-intent guide

How to source Phosphoric Acid 85% in bulk

Use these qualification points when comparing a China supplier, manufacturer source, distributor offer, bulk quotation or sample.

Food grade phosphoric acid 85% supplier

Qualify E338 identity, concentration, colour, chloride, sulfate, iron, arsenic, heavy metals and source-specific food documents.

85% phosphoric acid bulk quotation

State annual demand, packing preference, pallets, destination port, Incoterm and required delivery window.

Phosphoric acid for beverages

Provide beverage type, target pH and titratable acidity, mineral system, process and destination-market requirements.

E338 acidulant and pH control agent

Evaluate flavor impact, buffering demand, corrosion-compatible equipment, dosing accuracy and final-food compliance.

Application screening

Phosphoric Acid 85% food application screening

These are screening areas, not universal approvals, dosage recommendations or guaranteed outcomes. Confirm legal use and performance in the finished food.

Beverage acidification

Can be evaluated for suitable cola-style, flavored or processed beverages after taste and pH trials.

Food pH control

May provide strong acidification in permitted sauces, processed foods and ingredient systems.

Sequestration

Can support mineral-ion management in compatible formulations and processing steps.

Fermentation processing

May be evaluated for pH adjustment or nutrient-system control where the process and regulations permit.

Data note: Only the food-grade column from attachment 10 is shown. The source uses “no” for oxidizable matter and fluoride and does not state the colour method; these entries are preserved rather than converted into invented numerical limits. Confirm analytical definitions, methods and release criteria on the signed specification.

Technical selection

Questions to resolve before approving Phosphoric Acid 85%

Concentration basis

Confirm 85% w/w assay, density or concentration verification method and acceptable tolerance.

Equipment compatibility

Use corrosion-resistant storage, transfer and dosing systems based on the current SDS and site assessment.

Food impurity limits

Do not substitute an industrial-grade specification; approve the exact food-grade source and current COA.

Application validation

Set target pH and sensory endpoints through bench and plant trials rather than selecting a dosage from a generic webpage.

Qualification support

Documents and evidence to request

Product documents

Request the current signed specification or TDS, SDS, methods, representative COA and batch COA.
