An object of the present invention is to provide a konnyaku product in which scum causing smell and unpleasant taste is effectively reduced and that does not require a pretreatment for removing them, a production method therefor, and an alkaline coagulant suitable for the production of such a konnyaku. The object can be achieved by using, as an alkaline coagulant for konnyaku production, an alkaline solution containing non-reducing sugar, calcium hydroxide as an alkaline component for coagulation, and water, in which the non-reducing sugar and the calcium hydroxide are dissolved in the water.
