摘要:
本发明是关于一种小麦麸质蛋白的提取与改性方法,其特征在于由下列步骤完成:小麦麸皮→脱脂→高温a‑淀粉酶酶解→碱浸提→离心,取上清液→酸沉淀→离心,收集沉淀物→干燥→改性。琥珀酰化所引入的是带负电的琥珀羧基,电负性增加使蛋白质产生更强的静电斥力,降低了氢键的结合,从而减弱了蛋白质之间的相互作用,增强了蛋白质与水的相互作用,从而提高了其溶解性。
摘要(英):
The invention relates to a method for extracting and modifying wheat gluten proteins. The method is characterized by comprising the following steps: selecting wheat bran, degreasing, performing high-temperature alpha-amylase enzymolysis, alkali extracting, centrifuging, collecting supernatant, acid precipitating, centrifuging, collecting precipitates, drying, and modifying. Succinylation introduces succinate carboxyl with negative electricity, by improving the electronegativity, the proteins generate a higher electrostatic repulsive force, and the combination of hydrogen bonds is reduced, so that the interaction of the proteins is weakened, the interaction between the proteins and water is improved, and the solubility is further improved.
