abstract

introduction: the consumption of dietary fiber plays an important role in the prevention of illnesses such as diabetes type 2, hypercholesterolemia. dietary fibers are not only desirable for their nutritional properties but also for their functional and technological properties. this study was undertaken to investigate the possibility of alkaline hydrolysis to remove fiber from rice bran. material and methods: in this study, the extraction of fiber from rice bran was carried out in the presence of sodium hydroxide as an alkaline media and under autoclave condition. the response surface methodology was evaluated by the central composite design (ccd) to build a model based on three variables including the time (x1), temperature (x2) and the concentration of hydrogen peroxide (x3) for the extraction of fiber, and water binding and fat binding capacity of produced fiber. results and discussion: results showed that the optimum conditions for the maximum production of extracted fiber were 35min, 99.6 °c and 13.47% for time, temperature and the concentration of hydrogen peroxide, respectively. results indicated that temperature was the most significant factor influencing considerably on fiber extraction and fiber fat binding capacity and none of the parameters had significant effect in the level of (0.05) on the water binding capacity of fiber

Ultrasound 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 ...
