摘要： An object of the present invention is to provide an α-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 α-glucan mixture without adding any plasticizer.The above object is solved by providing an α-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.

摘要： The invention provides a process for enabling the production of a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside that does not significantly cake even when the production yield of ascorbic acid 2-glucoside does not reach 35% by weight. The process for producing a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside, which comprises allowing a CGTase to act on a solution containing either liquefied starch or dextrin and L-ascorbic acid and then allowing a glucoamylase to act on the resulting solution to obtain a solution with an ascorbic acid 2-glucoside production yield of at least 27%, purifying the obtained solution to increase the ascorbic acid 2-glucoside content to a level of over 86% by weight, precipitating anhydrous crystalline ascorbic acid 2-glucoside by a controlled cooling method or pseudo-controlled cooling method, collecting the precipitated anhydrous crystalline ascorbic acid 2-glucoside, and ageing and drying the collected anhydrous crystalline ascorbic acid 2-glucoside.
