Concentrated yoghurt is one of the most consumed dairy products in the world and is popularly known as Labneh in the Middle East or as strained yogurt in Greece and the rest of Europe (Senel et al., 2011).Labneh is a semi-solid fermented dairy food produced by draining some of the water and water-soluble compounds from yoghurt. The total solid (TS) content of the product is usually between 23 and 25 g/100 g, of which 8-11 g/100 g is fat, and it has a creamy/white color, a soft and smooth body, strong spreadability with little syneresis, and a clean, slightly acidic flavor (Hilali et al., 2011). However, as milk fat plays an important role in the texture, appearance, flavor, and color formation of dairy products, fat reduction in dairy products can result in defects such as a lack of flavor, a weak body and poor texture.Obesity is now a common cause of health conditions such as coronary artery disease, colon cancer, and adult-type diabetes (Aydinol & Ozcan, 2018;Prosky, 2000). As a result, consumers have recently expressed an interest in reducing their fat intake and increasing their consumption of low-fat foods. The importance of dietary fiber in human nutrition, as well as its effects on fermented dairy products, has resulted in a rising demand for novel fiber-based fat replacers (Aydinol & Ozcan, 2018;Elkot et al., 2020).Recently, in the dairy industry, there has been an increase in interest in using probiotic microorganisms as dietary supplements (El-Shafei et al., 2018). However, adding probiotic bacteria into the starter used to produce cultured dairy products has several drawbacks. In addition, probiotics can enhance lactose digestion with their digestive enzymes, minimize the side effects of antibiotics by improving the quick recovery of the human intestine after treatment
