| Abstract: | Objective]The study aimed to explore the study on physical and chemical properties of acacia extract. Method]The acacia juice was extracted by the ultrasonic and its 10 items of physical and chemical properties such as pH value,specific gravity,viscosity,containing fat rate,foam height,ethanol insoluble matter content and poisonous metal element content etc. were determined. Result]Acacia juice had a very good surface activity and the washing effect. It had pH value of 4.42,specific gravity of 1.015 g/ml,viscosity of 0.886 Pa·s,fat content of 1.553%,foam height of 75 mm,ethanol insoluble matter content of 6.004% and its heat resistance and cold resistance were good,reaching the standard of 1 grade product.Its 4 kinds of poisonous metal element content were follows:As was <10-6mg/kg,Cd was 5.55×10-4 mg/kg,Hg was <10-6 mg/kg and Pb was 4.47×10-3 mg/kg. The comparison on the detergency showed that the acacia juice could remove the dirt of 1.473 1 g and the washing liquor bought at market could remove the dirt of 1.324 5 g,indicating that the washing effect of the acacia juice was slightly better than that of the washing liquor bought at market. Conclusion]The acacia juice extracted by the ultrasonic had the stronger surface activity,its ability of removing dirt excelled to that of the washing liquor bought at market and its poisonous metal element contents were lower. |
