the hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of h+ to nabh4. the sulfonated porous carbon (spc) is used as a source of hydrogen ion and catalyst. it is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of nabh4 to generate hydrogen gas at room temperature in comparison to amberlyst-15 and nafion-nr50. the ki...

despite a highly beneficial role of water soluble arabinoxylans, the information about the effect of their addition on the properties of rye dough is lacking. the aim of this study was to check the influence of their modification methods and properties on water binding capacity of rye flour and suggest some possible explanations for the action of various fractions of arabinoxylans. three modifi...

Neutrase 0.8L and N120P proteases were used for oligopeptide production from apricot almonds meal, and response surface design was carried out to optimize the effect of hydrolysis conditions on hydrolysis degree (DH) and oligopeptide yield rate. Four independent variables were used to optimize the hydrolysis process: hydrolysis temperature (X(1)), enzyme-to substrate ratio (E/S) (X(2)), substra...

In this study, the hydrolysis of pretreated sorghum stem and rice husk was investigated at various initial enzyme concentrations and substrate loadings. The slowdown in enzymatic hydrolysis of lignocellulosic materials with conversion has often been attributed to decreasing the activity of enzyme. A kinetic model was developed and expressed mathematically based on enzyme deactivation for enzyma...

pectin is used as gelatinizing agent in food industry. in this study pectin was extracted from five commercial sugar beet varieties namely: doroty, rasul, 7112, br1 and ic using pre-hydrolysis technique. experiments were conducted using factorial design to verify the effect of temperature, time, percentage of hcl and water requirements on the extraction rate of pectin. the qualitative factors o...

lipase from candida antarctica, fixed on macroporous acrylic resin, has been used for the intermediate production of mono- and diolein by hydrolysis of triolein. the effect of altering concentrations of triolein and glycerol and the function of the molecular sieve on the hydrolysis reaction of triolein were investigated. the highest hydrolysis yield was observed for the utmost concentration of ...
