The bulgarian name for longevity

Nowadays, there is growing discussion about healthy living, which is associated not only with physical activity but also with nutrition. It is important to understand which foods have a positive impact on human health—one of the key indicators of longevity. This project focuses on Bulgarian yoghurt. A study was conducted to explore its significance for a healthy lifestyle, and the yoghurt-making process was examined through experimentation. Using descriptive and comparative methods, along with analysis of conducted experiments, the project achieved its goal: testing the conditions required for yoghurt fermentation—the optimal milk temperature and environment, and the influence of different starter cultures on the process. The research concluded that effective starter cultures have a higher fat content in the milk, and that the type of culture also affects the duration of the fermentation process.
