    This study involved the addition of gelatin and tannin in order to precipitate the colloidal materials which cause the turbidity of SHAHANI date juice.
    Different amounts of gelatin at different pH used, the best pH for clarification of date juice is 3.
    Best clarification was obtained when 0.4 cc of gelatin was added to 10cc date juice Brix 10, 15. Tannin has no effect on clarification, and at Brix above 20 gelatin unable to clarifying Date juice.
