The invention relates to a method for fractionating soluble fractions of peas, including, in sequence, a step of microfiltering or centrifuging, followed by a step of ultrafiltering, and optionally a reverse-osmosis step. A reduction of the leakage of proteins toward the soluble fractions, an improvement of the yield of the single concentration step by evaporating the soluble fractions, and the selective isolation of proteins of interest are thus achieved. The method is easy to implement, the devices used at each single step are conventional and well known to the person skilled in the art. Also, the method of the invention does not use any organic solvent other than water.

The present invention relates to maltooligosaccharides, the content of &#x3b1;-1,4-glycosidic bonds of which is between 70% and 80% of the total number of 1,4-type glycosidic bonds. The invention also relates to the method for manufacturing these maltooligosaccharides. Said maltooligosaccharides afford all the benefits of fiber-based foods, with an extremely low nutritional value. Such a compromise is particularly advantageous for use in healthy balanced diets, but also in the treatment and/or prevention of the pathology of diabetes. The invention also relates to the use of said maltooligosaccharides in the fields of human food and animal feed.
