Abstract:
This study comprehensively analyzes various powdered milk samples to elucidate their structural, surface, and mechanical properties. Through detailed examination, diverse characteristics among the samples were observed, shedding light on their behavior under different conditions. Notably, findings reveal intriguing insights into surface energy profiles, Harkins spreading coefficient, powder rheological properties, and sound absorption efficiency of the powdered milk samples. The intricate relationship between surface properties and bulk characteristics influenced the cooperative behavior of freely poured and consolidated milk powder beds, resulting in varying flowability from free-flowing to cohesive. Surface energy played a significant role in cohesiveness and dispersibility, with milk fat acting as a key mediator leading to changes in bulk dynamic-mechanical stiffness. These findings hold practical implications for formulating innovative aerosol-based dairy and cosmetic products, thereby enhancing everyday experiences.

The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
