Abstract
Background: Milk is considered one of the most widely recognized natural nutritious drinks in the world due to its importance in growth and health. This study aimed to prepare new functional milk drink formulas rich in nutrients and natural energy sources. Methods: This experimental analytical study was conducted by the Faculty of Public Health, Aljemail, Libya. Four new milk drink formulas were prepared: Formula 1 (fresh cow milk, date honey, banana, matcha, peanut butter, and white oats), Formula 2 (fresh cow milk, date honey, avocado, dark chocolate, and whey protein), Formula 3 (fresh cow milk, date honey, ginger, banana, dark chocolate, peanut butter, and whey protein), and Formula 4 (fresh cow milk, date honey, avocado, ginger, matcha, and whey protein). These formulas were assessed for their chemical quality characteristics (carbohydrates, protein, fat, ash, moisture, pH, total acidity, and total soluble solids), energy content, and sensory evaluation. Results: The results of the chemical analysis revealed a significant increase in the average percentage of carbohydrates, protein, fat, and ash, particularly for Formula 3, which presented the highest values of carbohydrates, protein, and fat (22.01 ± 2.127%, 11.21 ± 0.030%, and 3.79 ± 0.061%, respectively). The study also demonstrated that the new milk formulas contained high levels of total energy, especially Formulas 1 and 3, which had energy content of 143.47 kcal and 184.13 kcal, respectively. Sensory evaluation revealed that the panelists preferred all formulas, with general ratings of "excellent" and "very good." Conclusion: This study confirmed that natural additives can increase nutritional value and energy content. It is recommended to include these new milk drink formulas in the diets of youth,…
