“…In the scientific literature emulsions are defined as dispersions obtained from at least two immiscible fluids (such as oil and water) as a result of shearing and dispersion of one phase into the other [1][2][3][4]. The disperse phase droplets are dispersed in a continuous medium (liquid phase) [3,4].…”

Squalene is natural occurring polyprenyl compound with a linear triterpene chemical structure commonly found in animal and vegetal sources such as skin lipids from human body, liver of certain species of fish, especially sharks, crude vegetable oils (e.g olive, amaranth, palm oil etc.). Recently there has been an increasing interest in studying polymers that can be used as promising emulsions for drug delivery and vaccine applications. Recent studies proved that squalene has several beneficial and unique properties such as natural antioxidant, ensure skin hydration, biocompatibility. This can be used as such or for preparing stable and non-toxic emulsions. Herein we present the preparation and characterization of squalene oil-inwater emulsions stabilized by different non-ionic emulsifiers. Emulsion stability is a primary concern, therefore physical stability of squalene emulsions was also investigated. The major aim of the study was to find the optimal preparation conditions and assessing emulsion stability correlated with their viscosity and composition. In order to establish the connection between their physical stability and viscosity were performed rheological studies.

“…Many dispersion techniques have been developed to prevent coalescence inside the bubble getting larger in number. 107,108,164) Several physical processes can occur to decrease the overall free energy and destabilize the foam. 36) Drainage occurs through gravity; light gas bubbles rise, forming a denser foam layer, while the heavier liquid phase is concentrated below.…”

Porous ceramics are promising materials for a number of functional and structural applications that include thermal insulation, filters, bio-scaffolds for tissue engineering, and preforms for composite fabrication. These applications take advantage of the special characteristics of porous ceramics, such as low thermal mass, low thermal conductivity, high surface area, controlled permeability, and low density. In this review, we emphasize the direct foaming method, a simple and versatile approach that allows the fabrication of porous ceramics with tailored microstructure, along with distinctive properties. The wet foam stability is achieved under the controlled addition of amphiphiles to the colloidal suspension, which induce in situ hydrophobization, allowing the wet foam to resist coarsening and Ostwald ripening upon drying and sintering. Different components, like contact angle, adsorption free energy, air content, bubble size, and Laplace pressure, play vital roles in the stabilization of the particle stabilized wet foam to the porous ceramics. The mechanical behavior of the load-displacements curves of sintered samples was investigated using Herzian indentations testes. From the collected results, we found that microporous structures with pore sizes from 30 µm to 570 µm and the porosity within the range from 70% to 85%.

“…Untuk emulsi dengan ukuran droplet relatif besar (diameter >0,05 µm), pergerakan droplet didominasi oleh gaya gravitasi (McClements, 2011). Gaya gravitasi mengakibatkan proses pemisahan berupa kriming atau sedimentasi yang disebabkan oleh perbedaan densitas kedua fase (Leal-Calderon, 2012). Faktor utama yang mempengaruhi kriming pada sampel adalah perbedaan densitas diantara medium pendispersi (densitas air 0,9982 g/mL) dan terdispersi (densitas olein 0,8978 g/mL).…”

Palm oil emulsion drink is one of the food diversification product, containing high provitamin-A. The dispersed phase of the emulsion is palm olein, while the rest was water as the dispersion medium (ratio 7:3). The low content of dispersion medium in the emulsion ABSTRAKMinuman emulsi minyak sawit merupakan salah satu diversifikasi produk pangan dengan kandungan provitamin-A yang tinggi. Fase terdispersi emulsi ialah olein minyak sawit, sedangkan sisanya adalah air sebagai medium pendispersi (perbandingan 7:3). Rendahnya kandungan medium pendispersi dalam emulsi menyebabkan sifat reologi, ukuran dan distribusi droplet, serta tingkat stabilitasnya berbeda dengan produk minuman emulsi komersial lainnya. Penelitian ini mengkaji mengenai pengaruh waktu penyimpanan terhadap sifat reologi, distribusi ukuran droplet, dan stabilitas emulsi. Morfologi emulsi diamati dengan mikroskop polarisasi cahaya, sedangkan ukuran dan distribusinya dianalisis dengan teknik hamburan cahaya dinamis menggunakan Zetasizer. Analisis reologi, termasuk penentuan indeks perilaku aliran dan konsistensi, diukur menggunakan viskometer rotasional dial reading. Hasil penelitian menunjukkan bahwa peningkatan waktu penyimpanan menyebabkan meningkatnya ukuran dan distribusi droplet (nilai d4.3 dari 4,83 menjadi 6,12 µm), nilai indeks perilaku aliran (dari 0,978 menjadi 0,987), dan indeks konsistensi (dari 3,473 menjadi 5,047 Pa.s n ). Namun, kondisi ini juga menyebabkan penurunan stabilitas emulsi (dari 0,880 menjadi 0,823). Menurut koefisien korelasi Pearson, ukuran droplet berkorelasi negatif dengan stabilitas emulsi (R = -0,907; α = 0,01). Sebaliknya, ukuran droplet berkorelasi positif dengan indeks perilaku aliran (R = 0,778; α = 0,01) dan indeks konsistensi (R = 0,939; α = 0,01). Hasil penelitian ini dapat membantu memformulasi minuman emulsi minyak sawit dengan peningkatan stabilitas dan umur simpan.Kata kunci: distribusi ukuran droplet, minuman emulsi minyak sawit, sifat reologi, stabilitas emulsi PENDAHULUAN1Minyak sawit merupakan minyak nabati dengan perbandingan kandungan asam lemak jenuh dan tak *Penulis Korespondensi: Email: ekohari_p@yahoo.com jenuh yang seimbang, yaitu 40% asam oleat, 10% asam linoleat, 45% asam palmitat, dan 5% asam stearat.
