A starter culture is a mixture of microorganisms (such as bacteria or yeast) used to initiate fermentation or growth in various food products, pharmaceuticals, and biotechnological applications Its primary purpose is to:
1. Ferment sugars and produce compounds like lactic acid, ethanol, or carbon dioxide.
2. Enhance flavour, texture, and nutritional value.
3. Preserve food by creating an environment inhospitable to pathogens.
4. Produce antibiotics, enzymes, or other valuable compounds.
The common application of starter cultures can be found in yoghurt and cheese production
In essence, starter cultures kickstart the fermentation process, allowing the desired microorganisms to thrive and create the desired products.
