Lactic acid, 80 % (E 270) (5 kg) -

CAS-Nummer: 50-21-5 (unspez.),
Synonym: 2-hydroxypropanoic acid, 2-hydroxypropionic acid

Lactic acid (racemate), natural. Approved as food additive E 270. Organic acid for industrial purposes. Use in food and technical applications.

Application

Liquid lactic acid (racemate), as a 1:1 mixture of levorotatory and dextrorotatory lactic acid, is very commonly used for acid regulation in bakery and confectionery products or in beverages and for preservation. Likewise, lactic acid is used in lactofermentation and is used to preserve silages in feed production. In technical applications, lactic acid provides support through its biocidal effect and is therefore a component of disinfectant solutions and other cleaners. In addition, lactic acid is used for gentle decalcification.

Further information

Lactic acid is largely produced by fermentation. In the main, milk or whey is fermented by different Lactobacillus strains for this purpose in the food sector. Fermentative production enables the precise production of the L-isomer, which is in great demand for many innovative processes.

Storage

Store only in the original container in a cool, well-ventilated area. Keep container closed when not in use.
