膜浓度诱导酪蛋白胶束结构和胶体变化及其对环境交换条件的关系Structural and colloidal changes of casein micelles induced by membrane concentration and their dependence on the milieu exchange conditions 使用格哈特公司杜马斯定氮仪检测脱脂乳中酪蛋白含量和总蛋白含量 Casein content of retentates： Total protein contents of skim milk, UF and MF retentates, and their centrifugal supernatants were determined by nitrogen analysis using a Gerhardt Dumatherm (C. Gerhardt GmbH & Co.KG, K¨ onigswinter, Germany) and a conversion factor of N × 6.38. The protein contents referring to casein micelles (PCM) in skim milk and retentates were calculated by subtracting the protein content of their centrifugal supernatants (PSN) from the total protein contents (Ptotal): PCM = Ptotal − PSN
