摘　　要：以木薯淀粉为原料、十二烯基琥珀酸酐为改性剂,制备了两亲性木薯淀粉(ACS)。利用FT-IR、XRD、SEM表征了ACS的结构。通过表面张力探讨ACS在不同温度、不同盐环境及其与LAS、SDS、BS-12复配的表面活性;研究了ACS乳化性能和洗涤应用。结果表明,ACS的表面活性随温度升高而增大;无机盐提高ACS表面活性的能力大小依次为:MgCl_(2)、NaCl、KCl、CaCl_(2),MgCl_(2)降低表面张力高达25.7%;LAS、SDS、BS-12与ACS复配具有协同增效提高表面活性的作用,增效能力大小依次为:BS-12、SDS、LAS。ACS具有优良的表面活性和洗涤性能,与LAS、SDS协同洗涤效应显著。Amphiphilic cassava starch(ACS)is prepared with cassava starch as raw material,and dodecadenyl succinic anhydride as modifier.The structure of ACS is characterized by means of FT-IR,XRD,and SEM.By testing the surface tension,the surface activity of ACS is explored in different temperature and salt environment,and the surface activity of ACS combined with sodium dodecyl benzene sulfonate(LAS),sodium dodecyl sulfate(SDS),dodecyl dimethyl betaine(BS-12),respectively is also investigated.The emulsification property and washing application of ACS are studied.Study results show that the surface activity of ACS increases with increasing temperature.The ability of inorganic salts to improve the surface activity of ACS is successively MgCl_(2),NaCl,KCl and CaCl_(2).MgCl_(2)reduces the surface tension of ACS by 25.7%.LAS,SDS,and BS-12 all have a synergistic effect with ACS,improving the surface activity,and the synergistic capacity is successively BS-12,SDS,and LAS.ACS has excellent surface activity and washing performance,and has significant synergistic washing effect with LAS and SDS.
