本文研究了十二烷基氯和琥珀酸酐酰化的胃酶增溶的I型胶原的表面活性。与天然胶原相比，酰化胶原具有更好的表面活性，如吸油性、乳化活性和稳定性、泡沫膨胀性和泡沫稳定性，但吸水率较低。与吐温80相比，酰化胶原具有更高的乳化活性和稳定性，而吐温80具有更高的泡沫膨胀性和稳定性。酰化后，胶原蛋白的表面张力随储存时间的增加而降低，疏水性和润湿性随浓度的增加而增加。同时，随着氯化钠浓度在20~100 mm o l/L范围内的增加，酰化胶原的乳化活性和稳定性降低，在中性pH值下，当酰化胶原的浓度为0.4 mg/m L、温度较低(<；35°C)时，酰化胶原的乳化活性和稳定性较高。©2013威利期刊公司J.应用。波兰姆。SCI。2014年，131,40174。
The surface activity of pepsin-solubilized type I collagen acylated by lauroyl chloride and succinic anhydride was investigated in this article. Compared with native collagen, acylated collagen exhibited better surface activity such as oil absorption capacity, emulsion activity and stability, foam expansion, and foam stability but presented lower water absorption capacity. Acylated collagen also had higher emulsion activity and stability than Tween 80, whereas Tween 80 displayed higher foam expansion and stability than acylated collagen. After acylation, the surface tension of collagen decreased with the storage time increased, the hydrophobicity and the wetting power increased with the increase of the concentration. Meanwhile, the emulsion activity and stability of acylated collagen decreased with the increase of NaCl concentration ranging from 20 to 100 mmol/L. Under neutral pH value, acylated collagen reached higher emulsion activity and stability at acylated collagen concentration of 0.4 mg/mL and lower temperature (<35°C). © 2013 Wiley Periodicals, Inc.
