Lactic acid powder is produced by spray drying liquid lactic acid onto a suitable carrier such as calcium lactate, maltodextrin, or modified starch. This creates a free-flowing, easy-to-handle powder. The encapsulation process protects the lactic acid from premature interaction with other ingredients during storage and dry blending.
The powder typically contains 50-60% lactic acid on a dry basis and provides controlled acid release when dissolved or hydrated in the final application. It offers significant handling advantages over liquid lactic acid including reduced equipment corrosion, easier metering, and simplified dry blending operations. Lactic acid powder maintains the same mild, clean sour taste profile as liquid lactic acid while enabling applications that require dry ingredient formats.
