    • A method for flocculation of root or tuber juice is described having the advantage that dissolved protein remains unaffected and that clear potato juice with an OD620 below 0.8 is obtained. This is important for applications in which soluble protein is to be extracted from root or tuber juice, because it increases lifetime of the used equipment. The method involves a) use of a coagulant comprising a cationic coagulant and a flocculant comprising an anionic polyacrylamide with a specific viscosity of 4 - 6 m Pa•s and a charge density between 45 and 75 %; or b) use of a coagulant comprising a polymeric silicate of formula SiO 3 2- and a flocculant comprising a cationic polyacrylamide with a specific viscosity of 3 -5 m Pa•s and a charge density of at most 30 %; or c) use of a coagulant comprising a cationic or neutral coagulant and a flocculant comprising carrageenan. The invention further provides valuable root- or tuber derived materials, such as the floc material, a potato lipid isolate or an amino acid material.
    • 描述了根或块茎汁的絮凝方法,其优点是溶解的蛋白质不受影响,并且获得OD620低于0.8的澄清的马铃薯汁。 这对于可溶性蛋白质从根或块茎汁中提取的应用是重要的,因为它增加了二手设备的使用寿命。 该方法包括:a)使用包含阳离子凝结剂和絮凝剂的凝结剂,所述絮凝剂包含比粘度为4-6mPa·s的比例的阴离子聚丙烯酰胺和45-75%的电荷密度; 或b)使用包含式SiO 3 2-的聚合物硅酸盐的凝结剂和包含比较粘度为3 -5 m Pa·s且电荷密度至多为30%的阳离子聚丙烯酰胺的絮凝剂; 或c)使用包含阳离子或中性凝结剂的凝结剂和包含角叉菜胶的絮凝剂。 本发明还提供有价值的根或块茎衍生物质,例如絮状物质,马铃薯脂质分离物或氨基酸物质。
