Effect of low-dose irradiation of starter culture on fermentation and physicochemical properties of set-type yogurt

Key Points

• The aim is to explore how low-dose irradiation affects yogurt fermentation and its physicochemical properties.
• Applied low-dose irradiation to starter culture before fermentation.
• Measured fermentation time and viability of the starter culture.
• Assessed post-acidification and syneresis during storage.
• Evaluated physicochemical properties of yogurt samples.
• Increased fermentation time was observed.
• Decreased viability of the starter culture was noted.
• Improved post-acidification and syneresis during storage.
• Physicochemical changes were not significant enough to affect yogurt quality.
