INDUSTRIAL METHOD FOR PREPARING ALKALINE HYDROLYSATES OF VEGETABLE PROTEINS

摘要

The invention relates to a method for preparing alkaline hydrolysates of vegetable proteins, characterised in that it includes the following steps: 1) placing the vegetable proteins in suspension in water such as to have a concentration of 15 to 30 dry weight %, at a temperature of 70 to 80 °C and a pH of 9.5 to 10.5 by adding an alkaline hydroxide selected from the group made up of sodium hydroxide and potassium hydroxide; 2) allowing said suspension to incubate for 10 to 15 hours, at a temperature of 70 to 80 °C and a pH of 9.5 to 10.5; 3) neutralising said heated suspension by means of a mineral acid; and 4) drying the neutralised suspension such as to obtain the alkaline hydrolysate.
