“…Fat crystal dispersions were prepared by mixing MFC (Münüklü & Jansens, ) with sunflower (SF) oil (dispersion A) or a mixture of bean oil and palm kernel oil (dispersion B) at room temperature. The TAG composition of MFC and FA composition of the dispersions are presented in Supplementary Information (Tables S1 and S2).…”

The techniques that are currently available to assess fat crystal networks are compromised with respect to invasive sample preparation and ability to quantify compositional and structural features. Raman confocal hyperspectral imaging coupled to analysis with multivariate curve resolution can address these bottlenecks, as it provides label‐free, noninvasive chemical information in three dimensions (3D). We demonstrate the ability to acquire compositional maps of dispersions of micronized fat crystals (MFC) in oil, which contain local concentrations of liquid oil and solid fat with submicron spatial resolution and with acquisition times in the order of 10 min. From the compositional maps, we can derive quantitative information on the size and porosity of fat crystal flocs, as well as the solid fat content of the embedding continuous phase. Furthermore, the fractal dimension of the fat crystal network could be determined from the compositional maps via the box‐counting method and via the porosities of the crystal flocs. This makes it feasible to assess the validity of the weak‐link network theory under industrial relevant conditions. The confocal imaging mode allows for straightforward acquisition of 3D compositional cubes by recording a stack of two‐dimensional (2D) images. The box‐counting fractal dimension analysis performed on 2D maps can be extended to 3D cubes, which allows for straightforward verification that MFC networks are self‐similar rather than self‐affine.

“…To explore the potential of Raman confocal imaging for structural analysis of fat crystal networks, we will use dispersions of micronized fat crystals (MFC) in oil (Münüklü & Jansens, ). These systems can be considered models for the fat crystal networks that are present in margarine and chocolate.…”

“…124–126. Particle from gas‐saturated solutions (PGSS) stands out among other supercritical strategies since it for the foremost part does not require organic solvents. This procedure comprises the immersion of eatable liquid fats with SC‐CO 2 that are hence extended through a spout 127–129. Within the PGSS process, the polymer suspension and CO 2 is stacked into the high‐pressure cell, which is warmed and pressurized to SC‐CO 2 conditions to reach phase equilibrium.…”

Supercritical carbon dioxide (SC‐CO2) is CO2 that is stored beyond its critical point of 7.4 MPa and 31.1 °C. Given the request for consumption of a green solvent for the environment, SC‐CO2 is widely utilized in chemical, food, and pharmaceutical industries. To design material and drug production processes using supercritical fluid (SCF) technology, knowledge of their solubility is important. Temperature and pressure are the main factors in the study of solubility. Solubility data are then evaluated using equation of state, semi‐empirical, and intelligence models to establish suitable correlations. SC‐CO2 is one of the most important materials used in SCFs to study solubility. Another application of SC‐CO2 is in the field of material extraction to reduce the consumption of organic solvents. Nanoparticles production in drug industry is another advantage of SC‐CO2. Micro and nanoparticles can be produced using SCF techniques. In this review, the applications of SC‐CO2 in drug solubility, extraction of valuable materials, and nanoparticles production for pharmaceutical processes are reported and discussed. Finally, the main challenges are explained.

“…PGSS é usado para materiais com temperaturas de fusão relativamente baixas, como polímeros e lipídios. Esta técnica consiste na saturação do material de interesse com CO 2 supercrítico, seguida por expansão através de um bico aspersor Münüklü, Jansens, 2007). No processo RESS, o CO 2 supercrítico é usado como meio de extrair o material alvo em alta pressão; posteriormente, a solução supercrítica é despressurizada para atingir alta supersaturação para a geração de partículas finas (Yang et al, 2020).…”

Para a minha Tidinha... SÁBIA MULHEREu sou uma pessoa de sorte! Tenho uma avó sensível e, ao mesmo tempo, muito forte.Ela é matriarca de uma família cheia de amor.Plantou uma semente em nós e a levamos para onde for.O sorriso, sempre presente em seu rosto, ofusca qualquer marca da idade em seu pescoço.Os braços abertos, prontos para oferecer um abraço apertado para quem aparecer.Seu maior ensinamento é que o amor supera qualquer tormento.Falo e repito para quem quiser: Minha avó é uma sábia mulher. Talita, 2017 ... minha inspiração e saudade de todos os dias. Ai do céu, saiba que sempre vou te amar "Esta vida é breve, mas em sua brevidade nos oferece alguns momentos esplêndidos, algumas aventuras significativas. Na segunda estrela, vire à direita e siga em frente até o amanhecer. Viver é a coisa mais rara do mundo, a maioria das pessoas apenas existe" Destaque do livro "Sem ar" de Jenifer Niven ⸙ "Deus nos dá a parte feia para que possamos dar valor à parte bonita da vida" Destaque do livro "O lado feio do amor "de Colleen Hoover RESUMO BITTENCOURT, G.
