    The invention involves obtaining carbohydrates from vegetal raw materials. By the judicious utilization of adequate hydrolases and transferases it is possible to obtain carbohydrates totally crystallizable and soluble that might be stored over long periods without decomposition. Specific enzymes are added to pre-established substrates in four steps for reaction times of from 20 to 90 minutes at temperatures between 18`C to 67`C. Once the initial stage is ended the temperature in the heaters (3) is raised to 90/100`C to clot all impurities that remain then proceeding to a filtration or centrifugation to obtain the clean syrup about 13` Brix; the syrup is led to the vacuum concentrators (5) to eliminate practically all water, at a temperature not beyond 70`C around 70` Brix. Once the adequate saturation is reached to form the crystals, the product is mixed at low speed in the crystallizers (6) till the granules separate by themselves. The end product must have a relative humidity of less than 0.50%, preferably at 0.25%. The obtained concentrate is composed of carbohydrates without liquid stage. The process permits, as an option, that the concentrate be sent to a spray-dryer to form an even powder or granulate to be used directly or for further industrial use. The carbohydrates thus obtained can be used in industrial processes by means of known reactions, for example, oxidation, hydrogenation and fermentation. The latter includes fermentation processes for producing alcohol, yeasts, acetic acid and glutamic acid.

    The invention relates to a method for producing carbohydrates from vegetable raw materials,
    The method of obtaining the sugars is as follows
    Plant materials, such as sugar cane, beets or other plants containing carbohydrates, are crushed, subjected to extraction with an extractant to obtain juice in which dissolved carbohydrates are located. Then the juice is filtered, heated to. 90-100 ° C for the precipitation of proteins and subjected to enzymatic treatment in four steps at a pH of 3.5-8.0, a temperature of 18-67 ° C, and a process duration at each step of 20-30 minutes. At the first stage of enzymatic treatment, enter 3,2,1, 4-glucan-glucan hydrolase in the amount of 1.5 U and 3,2,1,15-poly-o - 1, 4-galacturon-glu kanhydrolase in the amount 0.9 U, at the second stage - 3,2,1, 20 - (- B-glucoside-glucohydrolase 0.3 U, at the third stage - 3,2,1,2 l - 3-D-glucoside-glu - cohydrase O, Z, 5,3,1,4-o6-arabinose -ketol-isomerase 0.15 U and 5,3,1,5-D-xylase-ketol-isomerase 0.15 U and at the fourth stage - 3.2, l-ci-l, 4-glucan-4-glucan hydrolase, 0.12 U, and 3.3.1, 4-glucan glucohydrolase, 0.22 U.
    The number and dosage of enzymes corresponds to the required amount required for processing 1000 liters of juice under normal conditions. The specified value of U is the amount of enzyme that can hydrolyze in 1 minute 1 mole of starch.
    In the enzymatic treatment process, carbohydrates, such as xylose, arabinose, starch, dextrins, peptides, rhamnose and galactose, are converted to glucose.
    At the end of the enzymatic treatment, the juice is heated to 90-100 ° C to inactivate the enzymes. The juice is then filtered and concentrated at a temperature of about 70 ° C to a CB content of 70. The resulting syrup is subjected to crystallization and dried to obtain granules or powder.
    Example. 1 t of sugar cane is cleaned, washed, crushed, subjected to extraction, the juice thus obtained is filtered. Filtered juice has 16 Briquet or 139.2 kg of dry matter, it is heated and maintained at 60 ° C .; pH of juice is 3.5. The juice
    subjected to enzymatic treatment in four stages.
    At the first stage, 3,2,1,4- - | L-1, 4-glucan-glucanohydrolase in an amount of, 5 and 3,2,1, 15-poly-o (: - 1, 4-galacturb -glucan hydrolase in the amount of 0.9 U; at the second stage - 3,2,1, 20-o -i-glucoside-glucohydrolase
    in the amount of 0.3 U; at the third stage - 3,2,1,21-pD-glucoside-glucohydrin-0.3 and, 5,3, 1, 4-oi-apa6nH03y-ketol-isomerase 0.15 U and 5.3, I , 4-D- -xylase-ketol-isomerase 0.15 U and. on
    Stage 5 - 3.2, l-ct-l, 4-glucan-4-glucan hydrolase 0.12 Pi 3,3,1,, 4-glucan glucohydrolase 0,22U. The duration of the steps is 20-30 minutes.
    An interruption of 15 minutes is effected between steps. After the reactions, the temperature of the juice is increased to 100 ° C for a time sufficient to coagulate the impurities and inactivate the enzymes. Juice after
    5 enzymatic processing contains carbohydrates having 6 and 12 carbon atoms, has a low viscosity and a pleasant smell. Then the juice is decanted, filtered and concentrated in evaporation
    0 vehicles up to 70 briquet. As a result of the enzymatic treatment, the viscosity of the juice is reduced and its evaporation is accelerated. Evaporation was performed under a vacuum of 100 mm Hg. and a boiling point of 52 ° C. After evaporation, the syrup is dried in a fluid-bed dryer and granulated (amorphous) sugar is obtained.
    To obtain crystalline CaQ hara, the syrup is boiled in a vacuum apparatus up to 90 Crixes and then fed into crystallizers and crystallized. After crystallization of the proposed method, the swelling is absent. When reached
    With Brike 96, the mass is cured into a homogeneous mixture of sugar and non-sugar. This mass does not contain substances with high viscosity. The resulting mass is crystalline, partly
    Q is amorphous, is homogeneous.
    The proposed method in comparison with the known reduces the energy consumption of the process and will increase by 30% the yield of the finished product.
