Product Overview

Leuconostoc mesenteroides is a Gram-positive lactic acid bacterium widely recognized for its essential role in food fermentation. As a starter culture, it initiates lactic acid fermentation in sauerkraut, pickles, kimchi, and other plant-based ferments, producing lactic acid and carbon dioxide that rapidly reduce pH and suppress spoilage microorganisms. Its ability to thrive in relatively high salt and sugar conditions makes it especially valuable for both vegetable and dairy fermentations.

Alfa Chemistry provides premium-quality Leuconostoc mesenteroides freeze-dried powder, designed to meet the needs of food manufacturers, dietary supplement developers, and fermentation professionals. The product is vegan-friendly and recognized as GRAS (Generally Recognized as Safe) by the FDA.
