The objective of this work was to study and identify the necessary processing steps for obtaining good quality sunflower seed protein concentrate and isolate when the oil is extracted with ethanol. This work is part of a research project on using ethanol as renewable solvent for sunflower seed oil recovery and possible further processing of the meal. Both 99 degrees GL and 90 degrees GL ethanol were employed in the extractions to produce the concentrate. Isolates were obtained by treating the concentrate with NaOH and HCl solutions and final rinsing with acidified water. Both products were light in color and almost free from chlorogenic acid.
这项工作的目的是研究并确定在用乙醇提取油脂时，获得高质量向日葵籽浓缩蛋白和分离蛋白所需的加工步骤。这项工作是一个研究项目的一部分，该项目旨在将乙醇用作可再生溶剂来回收向日葵籽油，并对粕进行可能的进一步加工。在提取过程中使用了99度GL和90度GL的乙醇来生产浓缩蛋白。通过用氢氧化钠和盐酸溶液处理浓缩蛋白，并用酸化水进行最终冲洗来获得分离蛋白。两种产品颜色浅，且几乎不含绿原酸。
