Description
Lactic Acid 80% Food Grade (E270)
We are a bulk lactic acid supplier of 80% food grade (E270). Lactic Acid 80% Food Grade (E270) (CAS 79-33-4, molecular formula C3H6O3) is a food-grade ingredient supplied to a published specification for food, beverage and nutrition manufacture, with traceability from batch through to certificate. China Chemicals supplies it at 80% w/w in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as E270, 2-Hydroxypropanoic Acid, Milk Acid. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Acidulant and preservative in beverages and confectionery
- Antimicrobial carcass wash in meat processing
- pH regulation in brewing and fermentation
- Descaling agent in food-plant CIP systems
- Monomer for polylactic acid bioplastic

What Is Lactic Acid 80% Food Grade?
Lactic acid exists as two mirror-image forms, L(+) and D(-). Food-grade production, including this lactic acid, uses fermentation of natural carbohydrates such as corn or sugar to produce the L(+) form, because it is the form the human body metabolizes efficiently and naturally produces itself, for example in muscle tissue during intense exercise. This 80% solution is a colourless to yellowish, nearly odourless, syrupy liquid with a mild acid taste. It is heat stable, so it holds up through typical food processing temperatures without degrading.
More Than Just Acidity
Lactic acid does more than lower pH. It acts as a bacteriostatic agent, inhibiting the growth of pathogenic bacteria, with documented effectiveness against organisms such as Salmonella and Listeria. It also depresses water activity, which further suppresses microbial growth independently of pH. That combination of acidulant, antimicrobial and water-activity control is why lactic acid performs several jobs at once in a food formulation.
Applications
Lactic acid is used for pH regulation and tartness balancing in dairy products and beverages, and to adjust pH during fermentation in brewing, winemaking and spirits. In baked goods and preserved fruit and vegetables it helps preserve colour and limit discolouration, and in meat and processed foods it contributes antimicrobial protection. For a sharper tartness profile, compare it with DL-Malic Acid, and for buffering see Trisodium Citrate. Outside food, lactic acid is valued in descaling products for its effective, biodegradable scale removal.
Handling & Safety
Lactic acid is non-toxic to humans and readily biodegradable in its diluted, in-use form. However, concentrated solutions, including this 80% grade before dilution, can cause skin irritation or corrosion and eye damage on direct contact. Wear gloves and eye protection when handling the concentrate. In Europe, E270 is permitted in foodstuffs on a quantum satis (as needed) basis except where specific product rules restrict it.
Frequently Asked Questions
Why is the L(+) form of lactic acid preferred for food?
It is the form the human body metabolizes more efficiently and naturally produces, which is why food-grade production targets pure L(+) lactic acid via fermentation.
Does lactic acid do more than lower pH in food?
Yes. It is a bacteriostatic agent with documented effectiveness against pathogens such as Salmonella and Listeria, and it also depresses water activity, adding microbial control beyond acidity alone.
Is concentrated lactic acid 80% safe to handle directly?
It is non-toxic in typical in-use concentrations, but the concentrated solution can cause skin irritation or corrosion and eye damage on direct contact, so gloves and eye protection should be used.
What does heat stable mean for this lactic acid?
It means the solution holds up through typical food processing temperatures without degrading, which matters for consistent performance in cooked, baked or thermally processed products.
What packaging and order quantities are available?
We supply lactic acid in a range of container sizes through to bulk IBC quantities. Contact us with your required volume for current pricing and lead time.
