Product type
Lactic acid culture is a type of fermentation agent used in food processing to produce lactic acid through the fermentation of carbohydrates. These cultures consist of specific strains of bacteria that convert sugars into lactic acid, contributing to the preservation, flavor, and texture of various food products. They are commonly used in dairy products, fermented vegetables, and meat processing, enhancing both safety and quality.
| Bacterial strains | Lactobacillus, Streptococcus, and Leuconostoc |
| Form | Powder or liquid |
| pH range | 4.0 to 6.0 |
| Fermentation temperature | 20°C to 45°C |
| Storage conditions | Cool, dry place, typically below 25°C |
When selecting lactic acid cultures, buyers should consider the specific bacterial strains needed for their application, as different strains can impart unique flavors and textures. It's also important to specify the desired fermentation conditions, such as temperature and pH, to ensure optimal performance. Certifications for food safety and quality standards may be required depending on the industry, so it's advisable to confirm these with suppliers.
