Since excessive sugar consumption causes health problems such as obesity, hypertension, and diabetes, in recent years, product development studies have focused on using natural or artificial low-calorie sweeteners instead of sugar (Beltrami et al., 2018).

The health effects of these products are mostly due to the probiotics they contain, and they have gained an important place among functional
