چکیده
Abstract Background Mechanochemical-assisted extraction (MCAE) and mechanochemical-assisted enzyme catalysis (MCAEC) methods were developed for enzymatic hydrolysis of calcium phytate from defatted rice bran, respectively. Results The MCAE conditions optimized by response surface methodology: 10% sodium carbonate as the solid reagent, 33 min grinding time, 18:1 ball–material ratio, 330 rpm ball milling speed, pH 5.5 extraction. Under these conditions, yield was 97.0 mg/g. MCAEC follows: 2% addition, MM400 time 36 min, PM400 speed 262 rpm, frequency 27 Hz, addition acetate buffer 3 mL. rate 39.7%. Conclusion Compared with traditional methods, could obtain higher yields rates, Graphical

Cellulase-assisted extraction of oligosaccharides from defatted rice bran.
Defatted rice bran was subjected to cellulase treatment in order to increase its extractable oligosaccharides. Various combinations of enzyme concentration (0%, 0.5%, 1.0%, and 2.0%), temperature (room, 30, 40, and 50 degrees C), and time (1, 3, 5, and 16 h) were tested to identify the optimum extraction conditions. The saccharide content and composition of the extracts were analyzed by high-pe...
متن کاملEffect of microwave and enzymatic treatment on the recovery of protein from Indian defatted rice bran meal.
Defatted rice bran meal is an important source of protein along with other micronutrients. Rice bran meal has been utilized to produce protein isolates for potential application in various food products. Attempt has been made to increase the protein solubility by physical means like microwave digestion as well as by microwave digestion followed by homogenization. Simple 40 sec microwave treatme...
متن کاملSubcritical Butane and Propane Extraction of Oil from Rice Bran
Rice bran oil was extracted using hexane, as well as subcritical butane and propane. The quality of rice bran oils obtained using these three solvents was comparatively studied. The results showed that subcritical fluid extraction oil showed higher concentrations of health-conducive components (such as vitamin E, oryzanol, and phytosterol) compared with hexane-extracted oil. Extraction solvent ...
متن کاملUltrasound Assisted Extraction of Oil from Rice Bran: A Response Surface Methodology Approach
In the present study, ultrasound-assisted extraction of oil from rice bran was investigated through response surface methodology (RSM), where process variables were amplitude level (50–100%) and sonication time (5-30 min). It was found that all process variables had significant (p<0.05) effects on the response variable. A central composite design (CCD) was used to determine the optimum process ...
متن کاملKinetic Modeling of Enzymatic Hydrolysis of Pretreated Sorghum Bicolor and Rice Husk
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...
