An object of the present invention is to provide an ±-glucan mixture in a preferable molecular weight range, which can be made into a transparent film with advantageous strength and water solubility when an edible film is made by using the ±-glucan mixture without adding any plasticizer. The above object is solved by providing an ±-glucan mixture, which is obtainable by a process comprising the steps of gelatinizing waxy starch and liquefying the resulting gelatinized waxy starch by allowing an amylase to act on it, having the following characteristics (1) and (2): (1) having the weight average molecular weight (Mw) in a range of 150 kDa to 3,000 kDa； and (2) having the value of dividing weight average molecular weight (Mw) with number average molecular weight (Mn), Mw/Mn, of 35.1 or lower.
