Stable complex of sodium caseinate and hexaglycerol monooleate with improved oil-in-water emulsion stability and curcumin encapsulation
To improve the emulsifying property of sodium caseinate (NaCas) as stabilizer of oil-in-water emulsions and encapsulation of bioactive compounds, three hexaglycerol mono-fatty acid esters were chosen as small molecular weight surfactants to complex with NaCas. Hexaglycerol monooleate (HGMO) was found to be the optimal surfactant and the optimal mass ratio was 1:1, through characterization of particle size, Zeta-potential, and turbidity. Fluorescence and FTIR spectra indicated that the hydrophobic interaction and hydrogen bond provided driving forces to the formation of stable complex. The complexation of HGMO to NaCas increased the surface hydrophobicity and decreased surface tension compared with NaCas, and strengthened the EAI and ESI. The NaCas-HGMO complex had good stabilization on rice bran oil-in-water emulsions, in a wide pH and ionic strength, and the forwarding Cur encapsulation in O/W emulsions dramatically reduced the degradation during storage at 4℃. Therefore, the present NaCas-HGMO complex might be employed as an effective emulsifier to stable O/W emulsions that load lipophilic bioactives in functional foods or beverages.
期刊介绍：
Biophysical studies of foods and agricultural products involve research at the interface of chemistry, biology, and engineering, as well as the new interdisciplinary areas of materials science and nanotechnology. Such studies include but are certainly not limited to research in the following areas: the structure of food molecules, biopolymers, and biomaterials on the molecular, microscopic, and mesoscopic scales; the molecular basis of structure generation and maintenance in specific foods, feeds, food processing operations, and agricultural products; the mechanisms of microbial growth, death and antimicrobial action; structure/function relationships in food and agricultural biopolymers; novel biophysical techniques (spectroscopic, microscopic, thermal, rheological, etc.) for structural and dynamical characterization of food and agricultural materials and products; the properties of amorphous biomaterials and their influence on chemical reaction rate, microbial growth, or sensory properties; and molecular mechanisms of taste and smell.
A hallmark of such research is a dependence on various methods of instrumental analysis that provide information on the molecular level, on various physical and chemical theories used to understand the interrelations among biological molecules, and an attempt to relate macroscopic chemical and physical properties and biological functions to the molecular structure and microscopic organization of the biological material.
