Plant pollens, naturally occurring microparticles, have gained much interest from various research areas owing to the unique architecture, mechanical properties, and resistance to biological degradation as well as chemical attack. In this study, we revisit the properties of Pickering emulsions of oil and water mixtures stabilized by the bee pollens. Interfacial tensions of various types of oils and water containing the dispersed pollen microparticles were systematically investigated. The significant reduction in the measured IFTs from those of the oils with pure particle-free water, in virtually all oil-water cases, strongly suggest the amphiphilic nature of the bee pollens, and hence the potential of the bee pollens in utilization as Pikcering emulsifers for versatile oil-water interfaces. Pickering emulsions prepared with the bee pollens in various experimental conditions, which were oil-in-water in most cases, displayed the remarkable stability for several months. |
