    摘要: PROBLEM TO BE SOLVED: To provide a method for producing ascorbic acid 2-glucoside anhydrous crystal-containing powder, which enables production of powder that is hard to solidify significantly, even when a yield of ascorbic acid 2-glucoside produced is less than 35 mass%.SOLUTION: A method for producing ascorbic acid 2-glucoside anhydrous crystal-containing powder comprises the steps of: causing CGTase to act on a solution containing either liquefied starch or dextrin and L-ascorbic acid, and causing glucoamylase to act on the solution to obtain a solution in which a percentage of ascorbic acid 2-glucoside produced is 27 mass% or greater; purifying the resulting solution such that the ascorbic acid 2-glucoside content exceeds 86 mass%; precipitating the ascorbic acid 2-glucoside anhydrous crystals by controlled cooling or semi-controlled cooling; and recovering, aging, and drying the precipitated ascorbic acid 2-glucoside anhydrous crystals.

    摘要: [Object] An object of the present invention is to provide a process for enabling the production of a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside that significantly, more hardly cakes, even when the production yield of ascorbic acid 2-glucoside does not reach 35% by weight. [Construction] The above object is solved by providing a 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.
