水化条件对大豆浓缩磷脂色泽品质的影响

Effect of Hydration Conditions on the Color and Qualities of Soybean Concentrated Phospholipid

研究传统的大豆油水化脱胶工艺中,水化温度、水化时间和水添加量对大豆浓缩磷脂Gardner色泽和理化性质的影响。结果发现,水化条件的选择应该综合考虑大豆浓缩磷脂的色泽、得率和丙酮不溶物的含量等因素,大豆浓缩磷脂的色泽随着水化温度增加,水化时间的延长而加深,水化时间过短会使水化不完全,大豆浓缩磷脂和大豆油的品质会受到影响,水的添加量不宜过少,否则磷脂得率会减少,影响大豆油品质。

In the traditional soybean oil hydration degumming process,the effects of hydration temperature,time and water addition on Gardner color and physicochemical properties of soybean concentrated phospholipids were investigated,it was found that the choice of hydration conditions should consider the color,yield and yield of soybean concentrated phospholipids.Factors such as the content of acetone insolubles,the color of soybean concentrated phospholipids increases with the hydration temperature,the hydration time was prolonged,the hydration time was too short,the hydration was incomplete,and the quality of soybean concentrated phospholipids and soybean oil was affected.Influence,the amount of water added should not be too small,otherwise the phospholipid yield will be reduced,making the quality of soybean oil worse.
