Abstract: The present invention relates to a method for preparing a legume starch with a high content of slowly digestible fraction (SDS), a heat-moisture treatment method characterized in that it comprises the following steps: 1) Adjusting the water content of the native pea starch to a value of less than 35%, preferably between 20 and 30% by weight, even more preferably between 20 and 25% by weight, 2) Heating the starch thus prepared to a temperature of more than 100° C., preferably from 105° C. to 135° C. for more than 5 hours, preferably for more than 10 hours, and even more preferentially for 24 hours, 3) Recovering and optionally drying the starch thus treated.

Abstract: A method for preparing a legume starch with a high slowly digestible fraction content (SDS), a hydrothermal treatment method wherein it comprises the following steps: 1) preparing a starch milk with a dry matter content of between 30 and 40% by weight; 2) heating the starch milk prepared in this way to a temperature of between 50 and 60° C., preferably 55° C., in a continuous reactor so that the residence time of the starch milk is less than 5 minutes, preferably less than 2 minutes; and 3) recovering, filtering and drying the starch milk treated in this way.

Abstract: The present invention relates to a method for preparing a legume starch with a high content of slowly digestible fraction (SDS), a hydrothermal treatment method characterized in that it comprises the following steps: 1) Preparing a starch milk with a dry matter content of between 30 and 40% by weight, preferably 32% by weight, 2) Heating the starch milk prepared in this way to a temperature 10 to 15° C. lower than its gelatinization temperature, 3) Stirring the starch milk obtained in this way at this temperature for between 45 minutes and 7 hours, preferably between 1 hour and 6 hours, 4) Recovering, filtering and drying the starch milk treated in this way.

Abstract: The invention relates to legume starches having a slowly digestible starch (SDS) content of 30 to 34% by weight, characterized in that they also have a very slowly digestible starch (vSDS) content of 34 to 40% by weight.
