中文摘要: 以烷基糖苷(C08~10APG)、脂肪醇聚氧乙烯醚硫酸钠(AES)、碳酸钠(Na2CO3)、硅酸钠(Na2SiO3)、柠檬酸钠(Na3C6H5O7)及戊二醛为主要成分配制乳制品设备原位清洗低泡清洗剂。通过摇瓶泡沫体积法筛选表面活性剂组分的配方量，通过正交试验确定助剂配方量。实验结果表明：当C08~10APG/AES的质量比为3∶1，总活性物含量为4%，质量分数为0.4%的二甲基硅油为消泡剂时发泡力较低，当Na2CO3/Na2SiO3/Na3C6H5O7质量比为6∶5∶9，助剂总质量分数为20%时，所配制的清洗剂去污率达到95.3%，并且具有很好的稳定性。杀菌试验结果表明：含戊二醛0.001%的样品对大肠杆菌和金黄葡萄球菌的杀灭率分别为92.33%和93.14%，放置7 d后对二者的杀灭率分别为91.08%和92.93%。
Abstract:The low foam cleaning agent for in situ cleaning of dairy equipment was formulated with alkyl polyglycoside (C08-10APG), sodium polyethoxy fatty alcohol sulfate (AES), sodium carbonate (Na2CO3), sodium silicate (Na2SiO3), sodium citrate (Na3C6H5O7) and glutaraldehyde as main constituents. The composition and dosage of the surfactants were screened and determined in accordance with the standard of low foam volume requirement through the Shaking-flask method. The formulation of additives was decided by using orthogonal experimental design results. The laboratory test results show that with the mass ratio of C08~10APG to AES as 3∶1 and the total surfactant content as 4%, foaming power of the detergent product achieves rather lower level with a mass fraction of 0.4% dimethicone as the defoaming agent. With the mass ratio of Na2CO3/Na2SiO3/Na3C6H5O7 as 6∶5∶9 as well as the total additives content as 20%, the product offers a high cleaning rate of 95.3% with high stability. The antibacterial test results show that the sterilization rate for Escherichia Coli and Staphylococcus aureus of the sample with 0.001% glutaraldehyde achieves 92.33% and 93.14% respectively, as well as 91.08% and 92.93% respectively after 7 d.
