Emulsified solid particles adsorbed at the oil-water interface can stabilize Pickering emulsions by acting as a phys. barrier to the coalescence of oil droplets. Cellulose nanofibres (CNFs) have been used in food-grade Pickering emulsions because of their excellent performance as a low cost and sustainable material. NMN (NMN) is a small-mol. zwitterion with polar functionality capable of interacting with the CNFs. The ability of cationic CNFs and NMN to co-stabilize sunflower oil Pickering emulsions was investigated under various conditions using methods such as contact angle measurement, creaming stability, rheol., microscopy, thermal stability, and water-holding capacity. Emulsions with ultra-high stability, good gelation, and high plasticity were obtained using single-step shear dispersion with 0.25 wt% CNFs, 0.05-0.3 wt% NMN, and near-neutral pH. NMN stabilized the oil-water interface through electrostatic interactions and hydrogen bonding with CNFs. NMN transferred into the aqueous phase and interacted with CNFs to form a complex with a three-dimensional network structure, which improved the bulk viscosity and steric hindrance of the emulsion and created more compact adsorption of CNFs at the oil-water interfaces. Overall, the synergistic effects of various factors allow NMN to effectively co-stabilize Pickering emulsions with CNFs, making it an exciting method that can be used to encapsulate oil-soluble substances. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Category: amides-buliding-blocks).
((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Category: amides-buliding-blocks
