豌豆可溶性蛋白与苹果果胶的复合凝聚沉淀Complex Coacervation and Precipitation Between Soluble Pea Proteins and Apple Pectin 使用格哈特Dumatherm N Pro杜马斯定氮仪快速测定豌豆可溶性蛋白和苹果果胶中蛋白质含量,苹果果胶使用6.25蛋白质系数,豌豆可溶性蛋白使用5.36蛋白质系数 The apple pectin was analyzed for protein content by determining elemental nitrogen (Dumatherm N Pro, Gerhardt GmbH & Co. KG, Königswinter, Germany) according to Dumas method by applying a nitrogen-to-protein conversion factor of N x 6.25. The pea protein isolate and soluble pea protein solutions (0.5% w/w) at pH 3–7 were centrifuged at 20,000 rpm for 30 min (Z 32 HK, Hermle Labortechnik GmbH, Wehingen, Germany). The protein content of the supernatant was measured by applying the Dumas combustion method using a Dumatherm N Pro device (Gerhardt GmbH & Co. KG, Königswinter, Germany). A nitrogen-to-protein conversion factor of 5.36 was used.
