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 ...
متن کاملComparative Studies between Conventional and Microwave Assisted Extraction for Rice Bran Oil.
The present work deals with comparison of microwave assisted extraction to that of conventional solvent extraction for the extraction of rice bran oil (RBO); focusing on extraction yield and oil composition. Microwave assisted extraction act as a green process over other method and proved that it is effective method for extraction of oil. The investigation also focuses on the study of functiona...
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 کاملTherapeutic Uses of Rice Bran and Its Components
Rice bran is the cuticle existing between the rice and husk of the paddy and consists of embryo and endosperm of the seeds of Oryza sativa, family Graminae. It is obtained as a byproduct in rice mill during polishing of rice obtained after dehusking of paddy. Rice bran contains about 15% of fixed oil and is obtained by solvent extraction method. It contains oleic acid, linolenic acid as unsatur...
متن کاملStudy on the Preparation Process of Rice Bran Oil by the Ultrasonic Enzymatic Extraction
The influence of oil rate and quality of rice bran oil by enzymatic extraction ultrasonic assisted were studied through designed experiment. The optimum enzymatic hydrolysis conditions were determined by the way of the orthogonal test. The results showed: after lipase enzyme in the rice bran (40 mesh sieve) was killed by the hot steam, the solution compounding material liquid ratio was 1:5 (W/V...
