摘要:
The present invention relates to a process for the purification of 1,3-propanediol from a fermentation medium of a 1,3-propanediol-producing microorganism, comprising 1,3-propanediol and fermentation coproducts consisting at least of glycerol, wherein the 1,3-propanediol-producing microorganism is separated from the other components of the fermentation medium to give a clarified aqueous solution, clarified aqueous solution is passed over a cation exchange resin to give at least one fraction comprising purified 1,3-propanediol and at least one fraction comprising the fermentation coproducts, and the 1,3-propanediol is recovered.
摘要:
The present invention relates to a process for the separation and purification of lactic acid from a fermentation medium wherein the lactic acid is totally or partially in the form of a salt or salts. The lactic acid producing microorganisms are separated from the other components of the fermentation medium. This solution is concentrated and then acidified to a pH below or equal to 3. The acidified solution is passed over a cation exchange resin to give a fraction that has maximum of 25% lactic acid salts relative to the dry weight of the solution. This fraction is subjected to bipolar fractionating electrodialysis. The resulting lactic acid is further purified, concentrated and then recovered.
摘要:
The subject matter of the invention is branched maltodextrins, characterised by the fact that they present between 22% and 35%, preferably between 27 and 34%, glucosidic linkages 1→6, a content of reducing sugars lower than 20%, a polymolecularity index lower than 5 and a number average molecular weight Mn at most equal to 4500 g/mole, and the method of obtaining these branched maltodextrins.
摘要:
A process for the conversion of an organic material comprising an oxidation step during which an organic material undergoes the oxidising action of an enzymatic means capable of generating hydrogen peroxide, wherein said oxidation step is carried out, wholly or partly, in the presence of 0.001% to 1% of a metal selected from ruthenium, palladium and mixtures thereof.
摘要:
The invention relates to a method of manufacturing a maltose-rich syrup, comprising the successive stages consisting of: (a) carrying out a liquefaction of a starch milk; (b) carrying out a saccharification of the liquefied starch milk in the presence of a maltogenic &agr;-amylase; (c) continuing the saccharification of the liquefied starch milk in the presence of a &bgr;-amylase and at least one debranching enzyme chosen from the group consisting of pullulanases and isoamylases with a view to obtaining a syrup which is rich in maltose.
摘要:
The invention concerns an immobilized maltogenic &agr;-amylase, which is adsorbed on particles of at least one porous substrate selected from the group consisting of phenolic resins, acrylic resins and polystyrene resins. The present invention also relates to the use of such an &agr;-amylase for the preparation of a maltose-rich syrup.
摘要:
The present invention relates to a process for crosslinking proteins, according to which the crosslinking agent is a ketose containing 3 to 5 carbon atoms and said proteins are chosen from the group comprising proteins from animal tissues, from milk or from blood, such as in particular casein, gelatin or collagen; proteins from cereals, such as in particular maize, wheat or rice proteins; protein from high-protein plants, such as in particular pea, alfalfa, lupin, barley, millet or sorghum proteins; proteins from oleaginous plants, such as in particular soybean proteins, for instance soybean cakes, rapeseed or flax proteins, for instance rapeseed cakes, sunflower, groundnut or cotton proteins; and proteins from tubers, such as in particular from potato or manioc.
摘要:
The invention concerns a process for the preparation of crystallised maltulose monohydrate, characterised in that it comprises the steps of preparing an aqueous maltulose solution of a strength above 65% by weight, concentrating the aqueous maltulose solution to a dry matter ratio of more than 50% by weight and at a temperature such that the degree of maltulose supersaturation is less than 1, cooling the concentrated solution so as to take the degree of maltulose supersaturation to a value above 1, crystallising the maltulose in said supersaturated solution by cooling it at a controlled speed and by stirring, obtaining the separation, recuperation and drying of the maltulose monohydrate crystals.
