摘要： A process for producing maltitol includes at least: producing a maltose syrup, by hydrolysis of a granular starch, in a first stage of liquefaction of granular starch to form a liquefied starch, followed by a stage of saccharification of the liquefied starch to which an aqueous solution of beta-amylase has been added, to form the maltose syrup; hydrogenating the maltose syrup to form an aqueous maltitol composition; and recovering the maltitol composition. The aqueous solution of beta-amylase also includes potassium sorbate, glycerol, and sodium carbonate.

摘要： A method for determining the degree of polymerization of a polymer is disclosed, the polymer being contained in a sample (2), the method comprising the following steps: a) illuminating the sample (2) using a laser beam (11) and acquiring (100) a Raman spectrum (S) representative of the polymer; b) identifying (110) a peak of interest (Pi) and determining (120) a position (vi) of the peak of interest in the Raman spectrum; c) on the basis of the position of the peak of interest, using a calibration function (ƒ) to determine a degree of polymerization (DP, DE) of the polymer, the calibration function expressing a variation in the position of the peak of interest as a function of the degree of polymerization of the polymer.

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.
