Effect of utilizing heart of date palm powder as a new source of dietary fibers, carbohydrates, and protein on the characterization and biological properties of low-fat bio-Labneh.

The heart of date palm powder serves as a valuable source of various biological macromolecules, such as dietary fibers and proteins, which contribute to its benefits as a health-enhancing ingredient. The main component of the heart date palm is carbohydrates, which provide a rapid energy source and its fiber content aids digestion and promotes feelings of fullness, thereby enhancing any diet. This research studied the possibility of incorporating the heart of date palm powder at varying concentrations (0, 3 %, 6 %, 9 %, and 12 % w/v) into low-fat bio Labneh made from a mix of camel and corn milk (75 %: 25 %). Over a 21-day cold storage period, adding the heart of date palm powder improved the textural properties, sensory qualities, and bioactive compound content of low-fat bio Labneh. Furthermore, no mold, yeast, or coliform bacteria were present throughout the 21-day cold storage. The total cell count of Bifidobacterium animalis ssp. lactis BB12 steadily increased until the 14th day of the cold storage. According to the sensory evaluation results, up to 12 % heart of date palm powder can be added to produce low-fat bio Labneh. This study lays the groundwork for further research into the use of heart of date palm powder as an innovative functional ingredient in dairy products.
