Inulin，as a kind of functional food ingredient，is added to the pearl milk tea for research and produce nowtype inulin pearl milk tea.In order to acquire the optimum extraction conditions of tea juice，influencing factors including tea and water ratio，extraction temperature，time of first and second extraction are studied by orthogonal test.The sensory scores of pearls are determined by evaluating the effect of the adding amount of inulin and brown sugar，starch gelatinization temperature and time through single factor and orthogonal experiments are implemented to get optimized formulation and preparation process for pearls.
