    • The present invention discloses a method for treating pectin containing plant material. The fresh plant material is adjusted to a pH between 3.2 and 3.9 at a temperature below 90°C to render the native pectin esterase in the plant material inactive. Thus, minimal deesterification takes place during transportation of the plant material, nor during subsequent washing and/or conventional drying of the plant material. Since the enzyme remains inactivated, the activity of the enzyme can be reestablished at a later point by increasing the Ph to above about 4.0. Pectin made from such treated plant material has a higher molecular weight and a lower calcium sensitivity than pectin made from the same plant material, which has not been subjected to said treatment.
    • 本发明公开了一种处理果胶含植物材料的方法。 将新鲜植物材料在低于90℃的温度下调节至3.2至3.9之间的pH,使得植物材料中的天然果胶酯酶不活动。 因此,在植物材料的运输过程中,也不在随后的植物材料的洗涤和/或常规干燥期间发生最小的脱酯化。 由于酶保持失活,因此通过将Ph增加到约4.0以上可以在稍后的时间点重新建立酶的活性。 由这种处理的植物材料制成的果胶具有比未经过所述处理的相同植物材料制成的果胶更高的分子量和更低的钙敏感性。
