摘要： The present invention relates to maltooligosaccharides, the content of α-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.

摘要： The present invention relates to a method for obtaining a preparation of β-amylases from the soluble fraction of starch plants, characterized in that the soluble fraction of starch plants is selected from the group consisting of the soluble fractions of wheat, pea, broad bean, horse bean, rice, barley, rye, buckwheat, potato and sweet potato, and preferably of wheat and barley, a clarification of said soluble fractions is carried out in such a way as to remove therefrom the insoluble substances and the colloids and, optionally, an ultrafiltration of said clarified soluble fractions is carried out in such a way as to obtain an ultrafiltration retentate containing the concentrated β-amylase and an ultrafiltration permeate, said ultrafiltration retentate containing the concentrated β-amylase is diafiltered and the resulting β-amylase is recovered.

摘要： An improved method for extracting β-amylases from a soluble fraction of a starch plant, includes a step of clarification by microfiltration and a step of concentration and purification by ultrafiltration. This method is characterized in that it uses a protease during the microfiltration step, making it possible to greatly reduce the fouling of the membranes used, which increases the production time before washing. Simultaneously, perfectly clear permeates are obtained, which assists with the subsequent ultrafiltration step and makes it possible to improve the transmission of β-amylase. Finally, the protease has no negative effect on the β-amylase activity.

摘要： A method for fractionating soluble fractions of peas, includes, 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 does not use any organic solvent other than water.
