Is E270 (Lactic acid) Halal?
Generally halal
E270 (Lactic acid) is usually made by bacterial fermentation of plant sugars and is generally accepted as halal; despite the name it is not necessarily from milk.
What is E270?
Lactic acid is a mild acid used to adjust acidity and preserve foods. Despite its name (from Latin for milk), commercial lactic acid is normally produced by fermenting plant sugars with bacteria, not from dairy.
Produced by bacterial fermentation of carbohydrates (such as corn or beet sugar), then purified. A dairy substrate is very rarely used.
Why is it generally halal?
Lactic acid is generally classified as halal because it is normally made by fermenting plant sugars, with no animal or alcohol component. The 'lactic' name does not mean it is from milk. As always, the finished product still needs its own verification.
