[0043] Example 1
[0044] A method for making orange juice based on membrane technology, including:
[0045] (1) Wash citrus and fresh orange fruits to remove foreign bodies on the peel;
[0046] (2) Peel and squeeze the cleaned citrus and fresh orange fruits to obtain the original fresh orange juice;
[0047] (3) The raw orange juice is filtered and separated by a ceramic membrane, the concentrated liquid obtained by the separation is fruit pulp, and the permeate is clear juice;
[0048] (4) The clear juice is concentrated by the forward osmosis membrane to obtain concentrated orange juice;
[0049] (5) The fruit pulp concentrate obtained in step (3) is pasteurized and thoroughly mixed with the concentrated orange juice obtained in step (4) to obtain the reconstituted raw juice, which is the final orange juice product.
[0050] The washing water in step (1) is preferably the product water produced during the regeneration process of the draw solution used in the forward osmosis membrane c...
