The present invention relates to a method for stabilising an aqueous solution of β-amylase, in particular by the use of glycerol, potassium sorbate and sodium carbonate. The cocktail of additives is particularly effective at maintaining the enzymatic activity of β-amylase over time. Another aim of the present invention consists of using the cocktail for the specific function of maintaining the enzymatic activity of the β-amylase. Another aim of the present invention is to provide an aqueous solution of β-amylase containing the aforementioned cocktail. A final aim of the present invention consists of using the β-amylase aqueous solution in bread-making, in malting, as a food additive, as a digestive agent, for sweetener production, in pharmacy and, finally, for maltose and maltose-enriched syrup production.
