Preparation method of high-transparency and stable tea bran water-phase extracting solution

The invention discloses a preparation method of a high-transparency and stable tea bran water-phase extracting solution, which comprises the following steps: (1) extracting; (2) flocculation and impurity removal; (3) decoloring; and (4) stabilizing. According to the method, plant debris, macromolecular proteins, pigments and emulsified tea seed oil in the tea saponin water extract are effectively removed, and then the tea bran water-phase extracting solution with high transparency is obtained. The obtained tea bran extracting solution has extremely high transparency, light color, high stability and high protein removal rate, and can be popularized and applied in daily chemical products. 本发明公开了一种高透明度和稳定化的茶麸水相提取液制备方法，由以下步骤组成，(1)提取；(2)絮凝除杂；(3)脱色；(4)稳定化。本发明有效去除茶皂素水提物中的植物碎屑、大分子蛋白与色素，以及被乳化的茶籽油，进而得到高透明度的茶麸水相提取液。本发明得到的茶麸提取液具有极高的透明度，较浅的颜色和高稳定性，蛋白去除率高，能够在日化产品中推广应用。
