Zeaxanthin is a yellow carotenoid antioxidant concentrated in the macula. This pigment in many foods and beverages is very problematic due to its extreme hydrophobicity and poor chem. stability. Solid lipid nanoparticles (SLNs) and nanostructure lipid carriers (NLCs) were prepared using a combination of high shear homogenization and ultrasonic methods to load zeaxanthin and reduce its hydrophobicity. In this study, NLCs containing zeaxanthin were produced and optimal formulation was determined and their physicochem. properties were investigated. 20% percent of solid lipid was replaced with Medium-chain triglyceride (MCT) as a liquid lipid to produce NLCs. Results showed that the particle size (PS) of NLCs did not exceed 130 nm, but SLNs did show larger sizes. In addition, particle dispersion index (PDI) showed 0.23 卤 0.01 to 0.34 卤 0.01 and 0.23 卤 0.01 to 0.30 卤 0.01 for SLN and NLC, resp. Zeta potential (ZP) represented -20.03 卤 0.48 to -12.11 卤 0.80 and -22.23 卤 0.41 to -16.88 卤 0.61 for SLN and NLC, resp. Encapsulation efficiency and loading were higher for NLCs than SLNs. The morphol. study of nanocarriers performed by scanning electron microscope (SEM) showed smooth spherical nanoparticles. Results of Fourier transform IR spectroscopy (FTIR) anal., and differential scanning calorimeter (DSC) showed that zeaxanthin was trapped in the nanocarriers without any chem. interaction with the coating material. Glycerol mono-stearate containing zeaxanthin showed phase separation after 60 days at 4 and 25掳C, while this was not observed in nanocarriers produced by glycerol distearate. Together, these nano-based carriers can be applied in many products, especially as nanocarriers for hydrophobic bioactive compounds in nutraceutical beverages. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Application of 31566-31-1).
Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application of 31566-31-1
