    摘要: PROBLEM TO BE SOLVED: To provide a method for producing an ascorbic acid 2-glucoside anhydrous crystal-containing powder, capable of producing a powder that will not show significant solidification, even when the percentage of ascorbic acid 2-glucoside produced is less than 35 mass%.SOLUTION: A method for producing an ascorbic acid 2-glucoside anhydrous crystal-containing powder comprises: a step in which a solution containing either liquefied starch or dextrin and L-ascorbic acid is exposed to CGTase and then to glucoamylase in order to obtain a solution where the percentage of ascorbic acid 2-glucoside produced is 27 mass% or greater; a step of purifying the resulting solution such that the ascorbic acid 2-glucoside content exceeds 86 mass%; a step of precipitating the ascorbic acid 2-glucoside anhydrous crystals by controlled cooling or semi-controlled cooling; and a step of recovering, aging, and drying the precipitated ascorbic acid 2-glucoside anhydrous crystals.
