The Fermentation Process
Yakult is produced through a fermentation process where the Lactobacillus casei Shirota bacteria convert lactose into lactic acid. This process not only gives Yakult its distinct tangy taste but also helps prolong the shelf life of the product.
The lactic acid created during fermentation plays a crucial role in preventing the growth of harmful bacteria, fungi, and other microorganisms that can spoil the product. The low pH level resulting from the lactic acid fermentation helps preserve the probiotic bacteria and maintain their viability.
The Role of Lactobacillus casei Shirota
Lactobacillus casei Shirota is a strain of beneficial bacteria that has been extensively studied for its potential health benefits. It is known to have a high tolerance to acidity and bile salts found in the stomach and intestines.
When consumed, the Lactobacillus casei Shirota bacteria in Yakult can survive the harsh acidic conditions of the stomach and reach the intestines intact. Once in the intestines, these bacteria can colonize and interact with the existing gut microbiota, potentially providing various health benefits.

It’s important to note that while Yakult doesn’t require refrigeration, storing it in a cool place can help preserve its taste and quality. Additionally, once opened, the product should be consumed within a specific timeframe to ensure the bacteria remain viable.
