Abstract In this study, rice bran protein was prepared by ultrasound-assisted extraction, and its physicochemical and emulsifying properties were also evaluated. Results demonstrated that a significant increase in protein yield was observed when ultrasound-assisted method was employed for extracting protein. Noticeably, obtained rice bran protein possessed excellent physicochemical properties, such as oil absorption capacity, protein solubility and foaming property. More hydrophobic groups were exposed in the process of ultrasound-assisted extraction, which led to the increase of surface hydrophobicity. More importantly, the ultrasound-assisted extraction could improve emulsifying properties of rice bran protein, and the emulsions prepared using protein samples exhibited the great stability. Besides, it was also found that emulsifying properties of protein samples presented a decrease trend with increasing ultrasound power and time. All in all, ultrasound-assisted extraction is a suitable alternative process for preparing rice bran protein.

Ultrasonic Wave was used to assist alkali extraction and acid precipitation of peanut protein isolate from defatted peanut powder. Based on the single factor test, the response surface analysis results shows that the Ultrasonic Wave-assisted Extraction condition is: ultrasonic power 210W, ultrasonic time 30min, ultrasonic temperature 40°C ,solid to liquid ratio 1:10.7, and under this improved condition the extraction yield could reach 80.09%.

There is a worldwide demand for phenolic compounds (PC) because they exhibit several biological activities. This work aimed at extracting phenolic compounds from peanut meal. The methods of extraction were mainly: conventional solvent extraction (traditional methods) and ultrasound assisted extraction (recent methods) and comparing their results. Peanut meal (PM) was prepared by defatting with n-hexane, and then extracted by the two previous methods. First, the conventional solvents used were 80% methanol, ethanol, acetone, isopropanol, and distilled water. Then studied Different parameters such as meal: water ratio, also the effect of temperature and the pH on the extraction process. Second, ultrasonic assisted extractions (USAE), the parameters investigated were temperature, time and speed of sonication. Finally, all the extracts were analyzed by HPLC for their phenolic contents. Results indicated that the highest extracted PC achieved by solvents was in distilled water where 1:100, Meal: Water ratio which extracted 40 mg PC / g PM at 30& 35°C. Highest extracted PC was achieved by alkaline medium at pH 12 more than acidic and neutral medium. While (USAE) at speed 8 ultrasonication and temperature 30ᵒC, extracted 49.2mg PC /g PM. Sothe ultrasound assisted extraction exhibited great influence on the extraction of phenolic compounds from peanut meal. The ultrasonic peanut extract was examined for its antioxidant, antimicrobial and anticarcinogenic activities. The antioxidant activity of PM phenolic extract prepared by ultrasonic technique, was measured by, β-carotene, and DPPH methods, and reducing antioxidant power. Results revealed values: 84.57, 57.72 and 5960 respectively. The PM extract showed different levels of antimicrobial activity against the pathogenic bacteria used. As for the anticarcinogenic effect PM phenolic extract most effective on inhibiting colon carcinoma and lung carcinoma cell lines with IC50 = 20.7 and 20.8 µ/ml., respectively. This was followed by intestinal carcinoma and liver carcinoma cell lines with IC50= 39.6 and 40.2µ/ml.
