Scientific Foundations
The scientific exploration into Matsoni fermentation involves complex interactions between bacteria and other microbes that enable the transformation of milk into a probiotic-rich product with distinctive qualities.
Microbiology of Fermentation
The microbiology of Matsoni fermentation is a delicate process orchestrated by specific microorganisms that convert lactose, the sugar in milk, into lactic acid. This not only gives Matsoni its tangy taste but also lowers the pH of the milk, which acts as a natural preservative. The presence of Lactobacillus and Streptococcus species primarily drives the acidification. This acidity level is crucial because it inhibits the growth of undesirable bacteria, ensuring both the safety and the unique flavor profile of the fermented milk.
Lactic Acid Bacteria
Lactic acid bacteria (LAB) are pivotal to Matsoni's fermentation, with Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus being the most prevalent strains. These LAB work synchronously: Streptococcus thermophilus produces formic acid which, in turn, stimulates the growth of Lactobacillus delbrueckii subsp. bulgaricus. This synergistic relationship is the backbone of the fermentation process, producing the characteristic tang of Matsoni and an array of beneficial probiotic bacteria. Traditional methods rely on back-slopping, where a portion of previous batches serves as the starter culture for the next.
Role of Yeasts and Other Microbes
In addition to LAB, a variety of other microbes including yeasts and Lactococcus lactis, contribute to the overall organoleptic properties of Matsoni. Yeasts such as Geotrichum candidum, Saccharomyces, and Candida are sometimes present in the microbial consortia and can influence the thickness and aroma of the product. Mesophilic cultures like Leuconostoc lactis and Lactobacillus helveticus may also be involved, operating best at room temperature, which is typically the environment for fermenting Matsoni. Modern techniques employ high-throughput amplicon sequencing to detail the biodiversity and understand the specific roles of these microbes in the fermentation matrix.
