salt extraction 解釋
鹽萃取
  • salt : SALT ＝Strategic Arms Limitation Talks 限制戰略武器會談。n 1 鹽，食鹽。2 【化學】鹽；酸類和鹽基化...
  • extraction : n. 1. 抽出，拔出。2. 【化學】提取（法）；萃取（法）；回收物，提出物；精煉。3. 精選，摘要。4. 血統，家世，出身。5. 【數學】開方，求根。

  3. With the increasing salt concentration, milk - clotting activity became higher and higher, then reached its peak, and then decreased gradually ; in the early extraction, the speed was quick, the milk - clotting activity was increased obviously. after it amounted to the maximum, the activity became steadily lower steadily ; the increasing temperature in extracting could improve the extraction activity, but too high temperature could result in the denaturation and inactivation ; the greater the ratio of abomasums and butter and was, the quicker speed was when the enzymes was drawn out, and after extracting for twice, most of the enzymes in the abomasums could be drawn out

    隨著食鹽濃度增大，凝乳活性逐漸提高，當達到一定濃度后，凝乳活性又逐漸降低；在提取初期，提取速度較快，凝乳活性明顯提高，當提取達到最大值后，凝乳活性又逐漸下降；隨著提取溫度的升高，凝乳活性逐漸增大，但溫度過高時，會導致酶變性失活；隨著提取液與皺胃比例的增大，酶溶出速度加快，提取次數越多，皺胃中酶提取越充分，提取2次后，皺胃中絕大部分酶被提出。
