Physicochemical characterization and emulsifying properties evaluation of RG-I enriched pectic polysaccharides from Cerasus humilis

Obtaining and studying the functional properties and determining the subsequent purpose in the practical use of pectin substances requires a thorough study of physical and chemical characteristics of the polysaccharide. By using the acidic hydrolysis method, pectic polysaccharides were isolated from nonconventional raw materials of natural origins - basidial fungus mushrooms Fomes fomentarius, Ganoderma lucidum, Inonotus hispidus, Polýporus squamosus. The polysaccharides isolated were characterized: such as content of free and etherifying carboxyl groups, total -СООН groups, -ОСН3 groups, degree of etherification and by data of the IR-spectroscopy. The pectic polysaccharides isolated in identical conditions from the basidial mushrooms were powders with colors from light yellow to is light-brown by the appearance, possess sub-acidic taste, have no extraneous smack and a smell. The pectin from Inonotus hispidus was much lighter than other pectins (Fomes fomentarius, Ganoderma lucidum, Polýporus squamosus). The pectin’s isolated were similar to the apple pectin by the organoleptic properties. They can classified as averagely etherified pectins regarding the degree etherification. Etherification degree of the studied pectins was in the range of 50.00–66.67%. The methoxyl groups were ranged between 8.47–11.43%. Content of free carboxylic groups in the range of 2.25–5.40%.

In this study, Hydrolysate from angelwing clam (Pholas orientalis) was produced at 0, 1, 2 and 3 hrs and E/S ratio of0.5 and 3%using alcalase where the pH and temperature were kept constant at pH 8.5 and 60°C, respectively. The hydrolysates were analysed for antioxidant and functional properties such as solubility, emulsifying properties and water and oil holding capacity. Degree of hydrolysis (DH), yield, functional and antioxidant properties were influenced by the hydrolysis time and E/S ratio. Higher enzyme concentration (E/S 3%) and longer hydrolysis time increased the DH. Yield was higher at E/S 3% but reduced with hydrolysis time. Longer hydrolysis time produced more soluble hydrolysate and higher metal chelating activity but lower in emulsifying properties and DPPH activity. Higher enzyme concentration resulted in increase only in solubility and metal chelating activity. This study revealed that enzymatic hydrolysis using alcalase should be performed at shorter hydrolysis time using intermediate concentration of enzyme (E/S between 0.5 to 3%) in order to produce angelwing clam hydrolysate with collectively good functional and antioxidant properties.

Solid dispersions are one of the most promising strategies to improve the oral bioavailability of poorly water soluble drugs. By reducing drug particle size to the absolute minimum, and hence improving drug wettability, bioavailability may be significantly improved. This article reviews the various preparation techniques for solid dispersion and compiles some of the recent technology transfers. The different types of solid dispersions based on the molecular arrangement have been highlighted. Some of the practical aspects to be considered for the preparation of solid dispersions, such as selection of carrier, solvent and methods of physicochemical characterization, along with an insight into the molecular arrangement of drugs in solid dispersions are also discussed. In this review, it is intended to discuss the recent advances related on the area of solid dispersions.
