The content of pineapple protease in pineapple stems is much higher than that in pineapple pulp. Therefore, the goal is to develop a low-cost and high-yield purification method for pineapple protease from pineapple stems, and use chromatographic technology to separate high-purity pineapple protease into high-unit Enzyme dosage, and use the remaining pineapple stems as raw materials to make candied fruit, reducing the waste of biological resources and increasing the high added agricultural value of pineapple products. |
